Render features

RenderFeature is responsible for drawing a given type of RenderObject.

Render phases

Render features have several phases.

Collect

collect phase determines what needs to be processed and rendered. It’s usually driven by the graphics compositor. The collect phase:

• -

  Extract

  extract phase copies data from game states of previously collected objects to short-lived render-specific structures. It’s usually driven by the RenderSystem and RenderFeatures. Prepare.

  Note

  prepare and draw phases are finished. Example tasks:
• -

  Prepare

  prepare phase prepares GPU resources and performs heavy computations. This is usually driven by the RenderSystem and RenderFeatures. Example tasks:
• -

  Draw

  draw phase fills the GPU command list. Example tasks:
• -

  Example

  Pipeline processors

  Pipeline processors are classes called when creating the pipeline state. This lets you do things such as enable alpha blending or wireframe rendering in a specific render stage. Xenko includes several predefined pipeline processors. You can also create your own.
