Path-Traced Rendering

Clavis PRO includes a GPU-accelerated path tracer for creating publication-quality images with physically accurate lighting, shadows, and depth of field effects.

​

Features

​

Global Illumination

Path tracing simulates real light behavior, producing soft shadows, ambient occlusion, and realistic material interactions automatically.

​

Depth of Field

Create professional-looking renders with adjustable focus and aperture:

​

Interactive Controls

​

Click-to-Focus (iPhone-style)

1. Enable Depth of Field in the RENDER tab
2. Click SET FOCUS to enter Focus Mode
3. Click on any atom to set the focus point
4. Drag vertically to adjust aperture:
   • Drag up = higher f-stop (sharper image)
   • Drag down = lower f-stop (more blur)

A yellow focus indicator will appear at the selected focus point.

​

Click-to-Position Light

1. Click SET LIGHT to enter Light Mode
2. Click anywhere in the 3D scene to reposition the light source
3. The light indicator sphere shows the current light direction

Post-Processing

​

Denoising

Enable the denoiser to reduce noise in lower-sample renders:

• Denoise Strength: 1-10 (higher = smoother but may lose detail)

Best Practices

1. Start with low samples (32-64) for previewing, then increase for final render
2. Use AUTO FOCUS to quickly center the focal plane on the scene
3. Enable shadows for more realistic renders
4. Adjust exposure if the image is too bright or dark
5. For publication figures, use the OSPRAY AO preset for clean, clear images

​

Export

Click EXPORT when the render is complete to download a high-resolution PNG image. The filename will include _pathtraced to distinguish it from standard screenshots.
