Implementation of Separating Axis Theorem intersection tests.
Test for an intersection between a line and an Axis-Aligned Bounding Box (AABB).
Returns 1 if they intersect, 0 otherwise.
|
extern |
Test for an intersection between a line and an Oriented Bounding Box (OBB).
Returns 1 if they intersect, 0 otherwise.
|
extern |
Test for an intersection between a triangle and an Axis-Aligned Bounding Box (AABB).
Returns 1 if they intersect, 0 otherwise.
|
extern |
Test for an intersection between a triangle and an Oriented Bounding Box (OBB).
Returns 1 if they intersect, 0 otherwise.
|
extern |
Test for an intersection between an Axis-Aligned Bounding Box (AABB) and an Oriented Bounding Box (OBB). The latter is defined by a center point and three perpendicular vectors from the center to the centers of the various faces.
Returns 1 if they intersect, 0 otherwise.
|
extern |
Test for an intersection between two Oriented Bounding Boxes (OBBs). The boxes are defined by a center point and three perpendicular vectors from the center to the centers of the various faces.
Returns 1 if they intersect, 0 otherwise.
