Main Features

ChemDoodle 3D is a powerhouse for working with chemistry in 3D with industry leading molecular modeling tools and best-in-class graphics.

  • 3D Visualization
    Image

    A new perspective on chemistry

    • Beautiful Scientific Models

      We spend a very long time scrutinizing the models generated in ChemDoodle 3D. Take a close look at the renderings as you are rotating them to watch bonds orient towards the camera; every object mesh in the scene is built to merge with the others; and our models are some of the most gorgeously crafted by any software in this industry.

    • Completely Customizable

      All of the rendering in ChemDoodle 3D is controlled by styles defined by you. The styles can apply to the entire scene, selected content or individual objects.

    • Advanced Text System

      ChemDoodle 3D’s advanced 3D graphics engine can render text beautifully. Use this to show atom labels and more. You have full control over font, size and color.

    • Custom Element Color Sets

      In addition to the predefined Jmol, Rasmol, PyMOL and CDK color sets, you can also manually define your own elemntal color set to apply to molecule rendering.

    • Compasses

      Include a compass on the bottom left of the graphic, or in the center overlaying the content, to describe orientation.

    • Projections

      Both orthographic and perspective projections are available and can be switched instantly.

    • Mesh Quality

      You can quickly change between various quality levels to benefit graphics output or to speed up performance.

    • Transparency

      Transparency effects are just that, they let you see through objects in the scene. ChemDoodle 3D allows you to render transparent objects with or without back faces.

    • Surfaces

      ChemDoodle 3D can generate a number of surface types and color functions for any number of atoms. Visualize the space of your structures in ways other editors cannot.

      You can customize mesh algorithms, display types, normals, colors and more.

      Different types of surfaces are available, including van der Waals (VDW), solvent accessible surfaces (SAS) and solvent excluded surfaces (SES, Connolly).

      Color your surfaces through various functions to provide a physical perspective on the structure. Functions include by atom color, charges (Gasteiger, QEq, QTPIE), lipophilicity (AlogP98) and molar refractivity (AMR98).

    • Orbitals

      View atomic orbital models based on quantum numbers with the Orbitals widget. Many options are available for customizing the graphics, which can then be output to an image. A great way to view the different orbital shapes.

    • Gamma Correction

      Gamma correction alters the brightness model of the graphics to compensate for the non-linear brightness physics of your monitor. ChemDoodle 3D defaults to a standard value of 2.2, but you can change this as appropriate for your screen.

  • Art
    Image

    Easily create ultra-realistic images, sketches, cartoons, paintings and more artistic illustrations

    • Shader Programs

      Shader programs are advanced instructions sent to the graphics card on how 3D graphics are generated. ChemDoodle 3D provides you with several built-in shaders to render your graphics, to create realistic styles like plastic and unrealistic styles like cartoons. Shaders in ChemDoodle 3D also provide additional features, such as outlining and shadows.

    • Lighting

      Control the color and direction of the lighting.

    • Shading Model

      A shading model is the method for converting the scene information into colors implemented by the shader program. Ambient-Diffuse-Specular (ADS) theory can be implemented in many different ways to create shaders that produce realistic graphics and non-realistic graphics. ChemDoodle 3D implements the following shading model types to choose from, all based on the ADS shading model:

      • None
      • Flat
      • Cartoon
      • Gouraud
      • Phong
      • Blinn-Phong

    • Renderers

      A renderer is the complete procedure in which we communicate with the graphics card using one or more shaders to produce a final image. In the simplest procedure, a single call is made to the graphics card where we pass in the scene data and produce an image with a single shader program. This is what we call a forward renderer.

      The downside of a forward renderer, is each pixel is calculated in isolation, limiting the techniques we can achieve. We can instead chain several rendering passes through the graphics card together, using the output of one complete pass as input into another. This allows the software to produce some advanced effects.

      In ChemDoodle 3D, you will find styles for 3 different types of renderers: (1) the forward renderer (2) the deferred renderer and (3) after effects.

    • Anti-aliasing

      Anti-aliasing smooths out the rough pixel edges in graphics (known as jaggies). ChemDoodle 3D supports both hardware (MSAA) and software (FXAA) anti-aliasing.

    • Shadows

      Fully customizable, real-time, dynamic shadows add a major sense of realism to your graphics.

    • 3D Textures

      Textures apply a surface styling to the objects rendered in the scene. This is done by defining some pattern in three dimensions, similar to how you would see three dimensional patterns if you were to cut into a block of wood. The objects are then crafted out of this pattern to produce the graphics, allowing you to produce a number of interesting styles. Choose from granite textures, wood, stripes and more.

    • Fogging

      Define fogging using linear, exp1 and exp2 algorithms. Give incredible depth to your graphics or focus on specific sections with these features.

    • Screen Space Ambient Occlusion

      Screen space ambient occlusion (SSAO) simulates the occlusion of ambient light in corners and crevasses of 3D objects. If you look in the corner of your room, it will appear slighly darker than the centers of the walls. This technique adds a significant amount of realism to the image and greatly helps with perception of topography. This technique is fully customizable in ChemDoodle 3D.

    • Outlining

      Outline effects are created by finding significant changes in cached data values from pixel to pixel. There are two types of outline algorithms provided in ChemDoodle 3D: Trace and Artistic. You can control colors, thicknesses, sketchiness and more!

    • Depth of Field

      A depth of field effect focuses in on a specific portion of your scene, emulating images made with camera lenses. You can define the beginning and ending focus depths as well as the extent of the unfocused blur and dilate effects.

    • After Effects

      After effects are advanced image filters. ChemDoodle 3D includes the following after effects:

      • Blur (Gaussian)
      • Blur (Kuwahara)
      • Blur (Median)
      • Dilate
      • Edge Detection
      • Pixelize
      • Posterize
      • Sharpen

  • Modeling
    Image

    Interact with your structures in real-time with advanced physical simulations

    • Real-time Optimization

      ChemDoodle 3D's molecular modeling procedures can be run in real-time (using the Minimizer widget) so you can interact with molecules while you are building them or easily change between conformations. Our modeling engine is fast and efficient, allowing you to quickly generate relevant 3D coordinates for your built structures.

    • The Optimization Function

      Define the optimization function used to minimize energies from several built-in search directions including steepest descent, conjugate gradients, FIRE, and BFGS, with several line search options.

    • Accurate Force Field Implementations

      ChemDoodle 3D includes implementations of several published force fields. Our implementations are some of the most accurate and consistent in the industry.

    • Universal Force Field

      The Universal Force Field (UFF) is excellent for quickly building partial and complete chemical structures for demonstrations and images as it can handle the vast majority of the periodic table. A complete implementation is included in ChemDoodle 3D.

    • Merck Molecular Force Field

      The Merck Molecular Force Field (MMFF94) and its static variant (MMFF94s) are both accurately implemented in ChemDoodle 3D. Use this force field to generate experimentally accurate geometries for measurements and calculations.

    • General Amber Force Field

      The General Amber Force Field (GAFF) is compatible with the Amber Force Field for proteins and nucleic acids.

    • VSEPR Force Field

      The Valence Shell Electron Pair Repulsion (VSEPR) force field is a very specific Points-On-a-Sphere (POS) force field. The entire purpose of this force field is to produce ideal shapes for VSEPR theory. The VSEPR force field is perfect for students and instructors to use and demonstrate why certain atom centers, along with electron pairs, lead to certain shapes in molecular structures. Up to 8 connections on a center and multicenter structures are acceptable.

      Because the purpose of the VSEPR force field is to generate shapes, energy calculations are irrelevant to the user, as they have no physical significance. When using the VSEPR force field, the Minimizer widget will instead display the current molecular geometry and VSEPR shape of the atomic center you are editing.

    • Scope

      Most small molecule force fields are optimized for describing individual discrete molecular structures. ChemDoodle 3D therefore will optimize molecular structures separately and individually as you are editing them. However, you may wish to optimize several discrete molecular structures at the same time and in relation to each other. To do this, you can change the optimization scope to optimize the entire scene.

      Please note, while you are able to optimize the entire scene, most force fields are not parameterized for multiple discrete molecular structures, and you will be relying on the through-space forces defined in the force field (mainly van der Waals and electrostatic), if defined at all. While minimizations of several discrete structures using through-space forces may look correct, please understand the theory behind the force field you are using and that any force field not specifically developed or parameterized for intermolecular forces will not lead to experimentally accurate coordinates.

    • Charge Models

      Several charge models are implemented in ChemDoodle 3D: Gasteiger-Marsili PEOE, MMFF94, QEq and QTPIE. You can also use these charge models to color molecular surfaces.

    • Atom Typing

      Atom typing is an essential step in the correct application of a force field. You can see what atom types are defined to the atoms in ChemDoodle 3D for the specific force field you are using. You may even output the atom types for use in other applications.

    • Force Rendering

      Forces can be rendered to show how the molecule will change given the force field gradient calculations.

    • Algorithm Transparency

      In addition to showing you the atom typing and force vector calculations, ChemDoodle 3D will let you know when a structure is not compatible with a specific force field by providing descriptive errors and warnings. Use all of this information for reliability and referencing.

    • Parallel Processing

      Parallel processing allows you to use the power of your multi-core CPU to speed up computations. The force fields in ChemDoodle 3D are specially designed to run in parallel. This means that your structure, which would normally take x seconds to optimize, will now only take a fraction of x seconds to optimize. Enable parallel processing in ChemDoodle 3D when you want to handle the optimization of a large structure or system. Understanding how parallel processing works and is implemented in ChemDoodle 3D is very important. We have an entire section covering parallel processing in the ChemDoodle 3D user guide.

    • Thorough Documentation

      New to molecular modeling? No worries. We have an entire chapter in the ChemDoodle 3D user guide dedicated to molecular modeling and how it is implemented. You will be optimizing structures in no time.

  • Symmetry
    Image

    Easily analyze and visualize the symmetry of your structures

    Symmetry Analysis

    Use the Symmetry widget in ChemDoodle 3D to analyze point groups and orders for your loaded or built chemical structures and selections of atoms.

    Visualization

    ChemDoodle 3D can render symmetry components, including inversion centers, rotation axes, reflection planes, and rotoreflection components. These renderings may be included in your scene, where you may define the colors, transparency, extent and other features of the graphics.

    Animation

    Easily orient and animate the symmetry components of your system using the Symmetry widget. This is a very useful tool for students and a great way to gain insight into your molecular structures.

    Orbits

    ChemDoodle 3D will separate your atoms into symmetrically equivalent groups, called orbits. You may even color your structure by orbit, for another method to portray the symmetry of your system.

    Symmetry features produced in collaboration with Professor Dean Johnston and symotter.org.

  • Stereoscopy
    Image

    Augmented reality on your computer

    Anaglyphs

    Anaglyphs are a stereoscopy technique used to show images in 3D space to our eyes from a 2D image. It works by rendering the scene for each eye's perspective in a different color space. Special glasses are then used to filter out each eye's image so one eye cannot see what the other eye sees. Our brain then pieces the two images together to observe the scene in 3D space.

    Hardware

    Anaglyphs are fully implemented with support for red-cyan, green-magenta, and amber-blue anaglyph glasses, which can be purchased cheaply from online retailers.

    Customization

    The Dubois method has been implemented for the most comfortable anaglyph viewing and you can control both the focal length and eye separation parameters to customize the anaglyph to your preference.

    • Feature Support

      ChemDoodle 3D supports as much of each format as possible, including meshes, normals, materials, transparency, colors and multicolors.

      Note some formats are less capable. For instance, the STL format cannot store colors, so use a more capable format like the VRML formats to suit your application.

    • Options

      Format specific options are also implemented, such as both binary and ASCII support for STL and PLY files and caching and compression for VRML files.


  • Small Molecules
    Image

    Build and visualize your molecules in 3D

    • Intuitive Controls

      ChemDoodle 3D’s building controls are made to clearly model the atoms and bonds they manage. Copious visual feedback is provided. There are also many options for customizing the building tools to your preference.

    • Advanced Selections

      Intuitive selection tools allow you to quickly trace, select and edit objects in 3D. For even more accuracy, use the Selector widget for a comprehensive organization of all the objects in the scene, allowing you to precisely investigate and select content.

    • 6 Bond Types

      6 physically relevant bond types are provided to create any type of chemical representation. No other program compares.

    • Smart Bonds

      ChemDoodle 3D renders multiple bonds that are able to orient themselves towards the camera for the most descriptive graphics.

    • Optimize Zone

      When building 3D structures, ChemDoodle 3D will automatically suggest the best place in three dimensions to add an atom connection. This helps you quickly build molecules. You can then simply turn on the minimizer to optimize physical coordinates. No other program has an optimize zone like ChemDoodle 3D’s!

    • Balls and Sticks

      You have full control over how atoms and bonds are rendered, and you can quickly choose from predefined representations, such as van der Waals spheres, ball and stick, stick, wireframe and line.

    • Show Labels

      ChemDoodle 3D’s advanced graphics engine can render text beautifully. Use this to show atom labels. You have full control over font, size and color.

    • Add Hydrogens

      Hydrogens will be added for you to your structures in appropriate 3D locations.

    • Implicit Hydrogens

      Implicit hydrogens are automatically tracked for your structures, but you can also override them as appropriate.

    • Attributes

      Define charges, radicals and isotopic mass values to atoms. These values are also properly read in and written to chemical file formats.

    • Electron Pairs

      Electron pairs and single electron (radical) objects are rendered on your structure and automatically placed for you (you may also manually place them). Use electron pairs in conjunction with the VSEPR force field to model VSEPR shapes.

    • Aromatic Representations

      Use toruses for aromatic circles or use resonance bonds that automatically orient to the center of rings.

    • Bond Deduction

      Automatically detect bonds in chemical files that do not contain bond data. Commonly, molecule data files do not include any bond information. Files including PDB, XYZ and output from quantum mechanics programs do not officially store bond data. Instead of having to draw bonds by hand, ChemDoodle 3D contains tools for deducing covalent bonds based on just the atom elements and 3D coordinates alone. ChemDoodle 3D can even assign bond orders to those bonds based on several algorithms, including "All Single", Antechamber and Auto-UFF.

    • Stereochemistry

      Perceive stereochemistry for 3D structures. CIP stereochemistry is determined for chiral centers, double bonds and allenes/cumulenes using our advanced and accurate CIP algorithms. Common cis/trans stereochemistry can also be determined for double bonds.

    • 3D Alignment

      Align molecular structures in 3D. Choose the mapping algorithm, whether to overlap the structures, or allow inversions.

    • Optimize Structures

      Quickly generate 3D coordinates for your structures using several algorithms.

    • Measurements

      Measure distances, angles and torsions in your structures.

    • Cheminformatics Functions

      Quickly access powerful functions to help modify your graphics: saturation, Kekulization, ring perception, distance geometry embedding, and more.

    • Database Lookup

      Search databases (PubChem, ChemSpider, ChemExper) for chemical structures and drag them right into your 3D scene using the MolGrabber widget.

  • Macromolecules

    • Macromolecular Transmission Format

      ChemDoodle 3D also fully supports the RCSB Macromolecular Transmission Format for incredibly fast input of Protein Data Bank files with full bond order information.

    • Protein Ribbon Models

      Beautiful protein ribbons and traces are generated. Tubes, cylinder and plank models and cartoon models can also be generated. These models can be segmented, colored and completely controlled through styles. For instance, you can change the ribbon thickness or the alpha helix width.

    • Nucleic Acid Ladder Models

      Accurate nucleic acid ladder models are generated. These models can be colored and completely controlled through styles. For instance, you can change the backbone thickness or the platform height.

    • Interpolation Algorithms

      ChemDoodle 3D can use either a B-Spline algorithm or the Catmull-Rom algorithm for generating models. The Catmull-Rom spline creates more accurate models, but the B-Spline algorithm produces smoother and more aesthetic results.

    • Residue Atoms and Bonds

      Control residue atoms and bonds separately from the rest of the structures for unique graphics.

    • Water

      Show and hide water atoms defined in PDB files and represent them with stars instead of spheres.

  • Periodic Systems
