class simvx.graphics.renderer.post_process.PostProcessPass(engine: Any)

Renders HDR scene to offscreen target, then tone-maps to swapchain.

The pass owns an HDR render target. When enabled:

• 3D scene renders to the HDR target (pre_render phase)

• Bloom extraction + blur (optional)

• Tone mapping + FXAA + cinematic effects renders to swapchain (main render pass)

Initialization

property enabled: bool

property hdr_target: simvx.graphics.renderer.render_target.RenderTarget | None

property bloom_enabled: bool

setup() → None

Initialize HDR target and tonemap pipeline.

begin_hdr_pass(cmd: Any) → None

Begin the HDR render pass (call before 3D rendering).

end_hdr_pass(cmd: Any) → None

End the HDR render pass.

render_bloom(cmd: Any) → None

Execute bloom pass (extract + blur). Call after end_hdr_pass.

render_tonemap(cmd: Any, width: int, height: int) → None

Render tone-mapped fullscreen quad to current render pass (swapchain).

resize(width: int, height: int) → None

Recreate HDR target and pipeline for new dimensions.

cleanup() → None

Release all GPU resources.
