Detailed Description

Forward rendering path.

Renders opaque geometry directly to the color/depth attachments using a single forward pass, then handles transparency and post processing passes. Suitable for scenes with many materials requiring complex shading (PBR, alpha test, etc.) without a G-Buffer.

overrideprotectedvirtual

Records the pipeline-specific color pass for the concrete renderer. Implementations dispatch scene draws into colorAttachment and depthAttachment.

Parameters

commandList	Command list to record into.
scene	Per-frame scene data.
viewport	Viewport rectangle for this frame.
scissors	Scissor rectangle for this frame.
clearAttachment	If true, the color attachment is cleared before rendering.
frameIndex	Index of the frame in flight.
