Rotation Center Behavior

When double-clicking to set rotation center:

Move Camera: Camera slides on view plane to center clicked point. Keep Camera: Only rotation target changes, camera stays in place. Keep Distance: Camera moves to maintain same distance from new center.

Color & Lighting

Gamma affects original vertex colors. Unlit PLY ignores scene lights. Choose Normal or Flat lighting for scene illumination.

Shading options are only effecting PLY files with faces.

Eye Dome Lighting enhances depth perception by darkening edges and silhouettes. Works with all geometry types and combines with any lighting mode.

Performance

Screen-Space Scaling: Distance-based point sizes for better visuals. Allow Transparency: Re-enables alpha blending (impacts performance).
