WebWe present a simple method for performing real-time collision detection in a virtual surgery environment. The method relies on the graphics hardware for testing the interpenetration between a virtual deformable organ and a rigid tool controlled by the user. The method enables to take into account the motion of the tool between two consecutive time steps. … WebgluLookAt is just a helper function, it provides a way to conviniently generate a view matrix that corresponds to the specified orientation. Instead of using that you can generate the matrix yourself in a variety of ways. For example you may have an orientation quaternion and a position vector for the camera and create the apropriate transformation

WebgluLookAt creates a viewing matrix derived from an eye point, a reference point indicating the center of the scene, and an UP vector. The matrix maps the reference point to the negative z axis and the eye point to the origin. When a typical projection matrix is used, the center of the scene therefore maps to the center of the viewport. Web24 mrt. 2006 · gluLookAt generates, and postmultiplies the active matrix by, a transformation matrix which includes a translation and a rotation.
