Module passes 

Built-in render pass implementations for a deferred rendering pipeline.

Each pass declares its resource inputs/outputs and contains simulated rendering logic. In a production engine, the execute methods would issue real GPU draw/dispatch calls; here they perform the bookkeeping and log what would happen.

Structs

BloomPass

Multi-pass bloom effect: threshold -> downsample chain -> upsample chain.

ClearValues

Simulated clear values.

DebugOverlayPass

Renders debug visualizations: wireframe, normals, G-Buffer channels, etc.

DepthPrePass

Renders scene geometry to the depth buffer only. Used for early-Z optimization and as input for SSAO, shadows, etc.

DrawCall

Simulated draw call for bookkeeping.

FXAAPass

Fast Approximate Anti-Aliasing post-process.

FinalCompositePass

Final compositing: combines all layers and presents to the swapchain.

GBufferPass

Fills the G-Buffer with albedo, normal, roughness/metallic, and velocity.

LightingPass

Deferred lighting: reads G-Buffer, shadow maps, SSAO; outputs HDR color.

SSAOPass

Screen-Space Ambient Occlusion, typically at half or quarter resolution.

ShadowPass

Renders shadow maps for a single light source. Typically instantiated once per shadow-casting light.

SkyboxPass

Renders the skybox / environment behind all geometry.

ToneMappingPass

HDR to LDR tone mapping with auto-exposure.

TransparencyPass

Weighted blended order-independent transparency.

Viewport

Simulated viewport.

Traits

BuiltinPass

Trait implemented by all built-in passes. Provides resource declaration and execution.

Functions

build_deferred_pipeline

Convenience function that builds a complete deferred rendering pipeline with all 12 built-in passes.
