Documentation
An axis aligned bounding box.
aabbTransform :: Mat44 Float -> AABB -> AABBSource
Transforms an 'AABB* using a 4x4 matrix. Note that this may grow the AABB and is not associative with matrix multiplication, i.e.
(m2 `multmm` m1) `aabbTransform` aabb
is usually not the same as
m2 `aabbTransform` (m1 `aabbTransform` aabb)
(The former is preferred as it minimizes the growing of the AABB).
testAABBprojection :: Mat44 Float -> AABB -> IntersectionSource
Try if an AABB is inside a projection frustum. The AABB must be defined in the same vector space as the matrix, e.g. use the model-view-projection matrix for model-local aabb's.
