cull_to_frustum – if True, triangles outside the view frustum will be culled.Ĭulling involves removing all faces which fall outside view frustum.ĭefault is False so that it is turned on only when needed.

See clip.py for all the extra computation that is required. Should only be turned on if explicitly needed. This avoids camera projections that go to infinity as z->0.ĭefault is None as clipping affects rasterization speed and Subdivided into smaller triangles) such that z >= z_clip_value.

The camera can be used to set the pixel aspect ratio.
