render_points(points, render_matrix, camera_cull_threshold=1e-08, return_w=False): 

LLM Docstring

Project a set of points through a render matrix into (culled) screen coordinates.

Points are homogenized, transformed, perspective-divided by their w component, and flagged as in-view when w exceeds camera_cull_threshold.

• points: np.ndarray

  the points to project

• render_matrix: np.ndarray

  the model-view-projection matrix

• camera_cull_threshold: float

  minimum w for a point to be considered in view

• return_w: bool

  also return the homogeneous w component

• :returns: tuple

  (projected_points, in_view_mask) (plus w if requested)
