isVisible() [1/3]

C3D_API bool castor3d::Frustum::isVisible	(	castor::BoundingBox const &	box,
		castor::Matrix4x4f const &	transformations ) const

Checks if given BoundingBox is in the view frustum.

Parameters

[in]	box	The BoundingBox.
[in]	transformations	The BoundingBox transformations matrix.

Returns

false if the BoundingBox is completely out of the view frustum.
