示例1: matMulVec
void computeBV<AABB>(const Sphere& s, AABB& bv)
{
Vec3f T = matMulVec(s.getRotation(), s.getLocalTranslation()) + s.getTranslation();
bv.max_ = T + Vec3f(s.radius, s.radius, s.radius);
bv.min_ = T + Vec3f(-s.radius, -s.radius, -s.radius);
}示例2: GraphicsCallback
//
// The Graphics Callback runs in the application "client thread" (qhStart) and sets the transformations
// for the Red Sphere and Green Line of the Cursor. Also, this callback sets the WorldToDevice matrix
// for use in the ServoLoopCallback.
//
void GraphicsCallback(void)
