Caster

Real-Time Physically-Based Renderer

Caster implements Google Filament's material model entirely in your browser using WebGL 2. Explore metallic, dielectric, cloth, and subsurface materials with real-time lighting, shadows, and post-processing.

Load your own models by dragging an OBJ or STL file onto the viewport, or use the file picker in the sidebar. Loaded models are processed locally — nothing leaves your browser.

Record turntable animations of your scene as WebM or MP4 video, and save screenshots at any time from the sidebar controls.
