◆ alloc_dummy()

RayTraceResult blender::eevee::RayTraceModule::alloc_dummy ( RayTraceBuffer & rt_buffer)

Only allocate the RayTraceResult results buffers as dummy texture to ensure correct bindings.

◆ render()

RayTraceResult blender::eevee::RayTraceModule::render ( RayTraceBuffer & rt_buffer,
GPUTexture * screen_radiance_back_tx,
eClosureBits active_closures,
View & main_view,
View & render_view )

RayTrace the scene and resolve radiance buffer for the corresponding closure_bit.

IMPORTANT: Should not be conditionally executed as it manages the RayTraceResult. IMPORTANT: The screen tracing will be using the front and back Hierarchical-Z Buffer in its current state.

  • rt_buffer is the layer's permanent storage.
  • screen_radiance_back_tx is the texture used for screen space transmission rays.
  • screen_radiance_front_tx is the texture used for screen space reflection rays.
  • screen_radiance_persmat is the view projection matrix used for screen_radiance_front_tx.
  • active_closures is a mask of all active closures in a deferred layer.
  • main_view is the un-jittered view.
  • render_view is the TAA jittered view.
  • force_no_tracing will run the pipeline without any tracing, relying only on local probes.
