class simvx.graphics.renderer.skybox_pass.SkyboxPass(engine: Any)

Renders a cubemap skybox behind the scene.

The skybox is drawn as a unit cube with depth test set to LESS_OR_EQUAL and depth written as 1.0 (far plane), so it renders behind all geometry.

Initialization

setup(cubemap_view: Any, cubemap_sampler: Any, render_pass: Any = None) → None

Initialize skybox pipeline with a cubemap texture.

When render_pass is provided, the graphics pipeline is compiled against it — needed when the skybox is drawn inside the HDR post-process render pass (R16G16B16A16_SFLOAT) rather than the engine’s default swapchain pass (B8G8R8A8_SRGB). Mismatched formats trigger VUID-vkCmdDraw-renderPass-02684 at draw time.

render(cmd: Any, view_matrix: numpy.ndarray, proj_matrix: numpy.ndarray, extent: tuple[int, int]) → None

Render skybox. Call after clearing but before scene geometry.

cleanup() → None

Release GPU resources.
