aabb3_detailed_volume_intersection

Constants

• scratch_aabb_corners : Array.<number>

• scratch_aabb_planes : Array.<number>

• scratch_corner_out_bitfields : Array.<number>

• scratch_v3_array : Array.<number>

Functions

• aabb3_detailed_volume_intersection(destination, destination_offset, x0, y0, z0, x1, y1, z1, planes, plane_mask, plane_count) ⇒ number

Figures out intersection volume between an AABB and a frustum for much tighter bounds

Especially beneficial when trying to intersect a large AABB against a small frustum, where where traditionally only AABB corners would be considered, we're instead able to compute minimum bounds of the overlap of the two
