This setting controls whether ray-traced images are rendered with or without perspective. Note that this can be in conflict with the setting "orthoscopic"; by default, images are rendered with the same orthoscopic setting as the viewport, unless "ray_orthoscopic" is deliberately set otherwise.
set ray_orthoscopic, off # render ray-traced images with perspective (2-4x SLOWER) set ray_orthoscopic, on # render ray-traced images without perspective
- For many images, the difference is hardly visible.
- Especially when straight features parallel to the z axis are shown, the effect may be large.
