class simvx.graphics.renderer.fog_pass.FogPass(engine: Any)

Compute-based volumetric fog: blends scene color with fog based on depth.

Supports linear, exponential, and exponential-squared distance fog, plus optional height-based fog falloff. Operates in-place on the HDR color image between the scene render and tone mapping.

Initialization

setup(width: int, height: int, depth_view: Any, color_view: Any) → None

Initialize fog compute pipeline and descriptors.

render(cmd: Any, inv_vp: numpy.ndarray, camera_y: float = 0.0) → None

Dispatch fog compute shader. Call after HDR pass ends, before tonemap.

Args: cmd: Active command buffer (outside any render pass). inv_vp: Inverse view-projection matrix (row-major numpy). camera_y: Camera world Y position for height fog.

resize(width: int, height: int, depth_view: Any, color_view: Any) → None

Update descriptors for new dimensions.

cleanup() → None

Release all GPU resources.
