Detailed Description

Simple 8-point Vec3f cube compound having z-far <= z-near @endiliteral.

8-points from far to near (z), left to right (x) and bottom to top (y) in AABB case, otherwise arbitrary

lbf, rbf, rtf, ltf
lbn, rbn, rtn, ltn

A cube can be used to transform an AABBox from object-space to e.g. model-view (Mv) space via Cube(AABBox) and transform(Matrix4f) as required for an Mv Frustum presentation, see updateFrustumPlanes(Frustum).

◆ updateFrustumPlanes()

Frustum com.jogamp.math.geom.Cube.updateFrustumPlanes ( final Frustum frustum )

Calculate the frustum planes using this Cube.

One useful application is to transform an AABBox, see Cube#Cube(AABBox) from its object-space into model-view (Mv) and produce the Frustum planes using this method for CPU side object culling and GPU shader side fragment clipping.

Frustum plane's normals will point to the inside of the viewing frustum, as required by the Frustum class.

Parameters

frustum the output frustum

Returns: the output frustum for chaining
