Features
Path-Traced Lighting
Every pixel is computed by tracing light paths through the scene. The result captures ambient occlusion, soft shadows, and color bleeding between nearby atoms - subtle cues that give the viewer an intuitive sense of three-dimensional structure.
Depth of Field
Simulate a camera lens to draw the viewer's eye to a region of interest.
Depth-Aware Outlines
Depth-aware outlines can reveal structure that may otherwise be obscured.
Rendering Styles
Mix and match rendering options to find the right look. Presets provide quick starting points - Default, Toon, Illustration, and Licorice - or dial in your own.
Video & Image Export
Record smooth camera animations with keyframe control, including rotation, rocking, and fully custom camera paths. Trajectory playback can be synchronized with camera animation for molecular dynamics visualizations.
Molecular Dynamics
Load multi-frame XYZ files and scrub or play back trajectories in real time.
