====== Ray tracers ====== GroIMP contains two built-in ray tracers, which can utilize a set of different ray processors. The ray tracers can be used for both light modeling and rendering. To use the renderer, select it as your Render View: {{:user-guide:3d_view.png}} When starting any of these renderers, your Scene will be rendered as an image using the current camera viewpoint. In case it takes too long, you can interrupt the process with stop. In some cases, this might not work and GroIMP dies, so be sure to save your project before experimenting with the renderers. When you moove the camera after the renderer has finished, the 3D View switches back to the default "interactive" OpenGL renderer. ====== ====== {{namespace>01_user_documentation:08_light}}
