Rendering
GroIMP includes different approaches for rendering the current scene with accurate lighting and details.
Twilight renderer
This is the so-called “Twilight” renderer. Included are a the “standard ray tracer”, a path tracer, photon mapping, a bidirectional path tracer, and processors for radiosity as well as metropolis light transport. The raytracers can be used for both light modelling within your RGG model as well as for rendering your scene. The following introduction covers the raytracing settings when used for rendering. To use the Twilight renderer,
Flux renderer
The GPUFlux plugin also provide a renderer on the GPU. This renderer is accessible from the 3D view, under Render View>Flux Renderer.
External renderer
External renders can be used to create a 3D view of higher quality. The POV-Ray Plugin provides a scene export to the POV-Ray format which makes it possible to use the free ray-tracer POV-Ray as an external renderer, see the POV-Ray manual. The resulting image is directly shown in GroIMP's 3D view.
