Function Documentation

Tpqp* DefinePQPModel ( double **  v,
unsigned int  nf,
unsigned int *  nvf,
unsigned int **  fv 

Adds a polyhedron to the pqp system. Note that pqp only accepts triangulated geometry. So spsheres and cylinders need to be triangulated to send them to pqp. This implies a reduction in the accuracy of the collision detection. Moreover, non-triangular faces of the polyhedron must be triangulated.

vThe vertexes of the polyhedron.
nfNumber of faces.
nvfNumber of vertices per face.
fvThe indexes of the vertexes forming each face.
The identifier assigned to the new object.

boolean PQPTest ( THTransform t1,
Tpqp m1,
THTransform t2,
Tpqp m2 

Test for collision.

t1The transform to apply to the first PQP model. NULL if no transform need to be applied.
m1The first PQP model.
t2The transform to apply to the second PQP model. NULL if no transform need to be applied.
m2The second PQP model.
TRUE if there is a collision.
