Detailed Description

A full global illumination renderer.

This class implements an rsm_renderer and enhances it to provide a full scale GI solution. This is done via Light Propagation Volumes or Voxel Cone Tracing. Because both are volumetric solutions and share almost all code, you can switch between both with a define #LPV. If #LPV is set, a Light Propagation Volume is used, otherwise a Sparse Voxel Octree will be instaniated.

void gi_renderer::render_gi ( ID3D11DeviceContext *  context, float *  clear_color  )

inlineprotected

Compute global illumination for the scene.

This method first makes sure that the RSM/GI solution needs to be updated. If so, a new RSM is rendered for one directional light, which will then be injected into a volume and further processed.
