|3D graphic features|
Extreme OpenGL implementation for an incredible real-time rendering quality: lighting (4 customizable light sources + ambient light), alpha blending, hardware anti-aliasing, material management, 3D backgrounds.
Stereo view (shutter or anaglyphic glasses).
|-||10 bit output for each color channel for a smoother view (230 = 1.073.741.824 vs. 224 = 16.777.216 colors).|
Cluster rendering (WireGL).
3D molecule view: wireframe with multivector bonds, CPK, ball & stick, stick, trace and tube. All representations can be mixed thanks to the selection tool.
Atom labels (atom name, element, atom type, atom number, atomic charge, chirality, fixing value, residue, residue name, residue number).
Enhanced atom coloring methods: atom, residue, chain, segment, molecule, constraints and custom.
Atom selection & picking.
3D surface: dotted, mesh, solid, solid transparent. Thanks to the HyperDrive technology, the calculation is very fast. The surfaces can be colored by atom, residue, chain, segment, molecule, surface ID and property. The color gradient used in the property coloring mode can be customized by the user defining the number and the type of colors.
Multiple surface management.
All 3D object can be managed with mouse, joystick and dials (rotation, translation, scale and animation).
3D interactive monitors calculated in real time (distance, angle, torsion and angle between two planes).
Simulation trajectory visualization and animation with full support for Accelrys archive file (.arc), AutoDock 4 DLG, BioDock output, CSR (Accelrys conformational search), DCD, ESCHER NG, Gromacs XTC, IFF/RIFF (32 and 64 bit), MDL Mol multi-model, Tripos Mol2 multi-model, PDB multi-model and PDBQT multi-model formats.
Snapshot, hardware and software image rendering with the capability to create images bigger than the monitor size. The software rendering includes an anti-aliasing algorithm with user-selectable 4x or 16x super sampling. The supported output formats are: BMP, GIF 256 colors, JPEG, PCX, PNG, PNM, RAW, SGI, TGA and TIFF.
Vector graphic rendering engine. It's possible to export the view in LaTex, PostScript, Encapsulated PostScript, PDF, POV-Ray, SVG and VRML 2.0 formats.
Native video compression for animations: the trajectory files can be converted in real animation files (AVI, MPEG-1 and MPEG-2) without external software. VEGA uses the Windows codecs for the standard AVI files and a built-in library to encode MPEG-1 & 2 streams. The MD animations can be converted in DVD, Super Video CD, Video CD and video streams for the Web in easy way.
