class simvx.graphics.scene.frustum.Frustum¶

View frustum defined by 6 planes for culling.

Initialization

extract_from_matrix(vp: numpy.ndarray) → None¶

Extract frustum planes from view-projection matrix.

Planes: left, right, bottom, top, near, far.

test_sphere(center: numpy.ndarray, radius: float) → bool¶: Test if sphere intersects or is inside the frustum.

test_aabb(min_bounds: numpy.ndarray, max_bounds: numpy.ndarray) → bool¶: Test if AABB intersects the frustum.

cull_spheres(centers: numpy.ndarray, radii: numpy.ndarray) → numpy.ndarray¶

Vectorized frustum cull for many bounding spheres.

Args: centers: (N, 3) array of sphere centers. radii: (N,) array of radii.

Returns: boolean mask (N,) — True = visible.
