class simvx.graphics.renderer.shadow_pass.ShadowPass(engine: Any)

Renders depth from directional light’s POV into a cascaded shadow map atlas.

Atlas layout: CASCADE_COUNT images side-by-side horizontally. Total size: SHADOW_MAP_SIZE * CASCADE_COUNT × SHADOW_MAP_SIZE.

Initialization

setup(ssbo_layout: Any) → None

Initialize shadow map resources.

property shadow_texture_index: int

Bindless index of the shadow map atlas texture.

compute_cascades(view: numpy.ndarray, proj: numpy.ndarray, light_dir: numpy.ndarray, near: float = 0.0, far: float = 0.0) → None

Compute cascade split distances and light-space VP matrices.

Delegates to shadow_math.compute_cascades and transposes to GLSL column-major for the SSBO upload.

render(cmd: Any, instances: list, ssbo_set: Any, mesh_registry: Any) → None

Record shadow depth rendering commands.

cleanup() → None

Release all GPU resources.
