Web22 de ago. de 2012 · In legacy OpenGL, this is accomplished by the gluLookAt () function, so we'll call this the "look-at" camera. Let C be the camera center, p be the target point, and u be up-direction. The algorithm for computing the rotation matrix is (paraphrased from the OpenGL documentation ): Compute L = p - C. Normalize L. Compute s = L x u. (cross … Web8 de jul. de 2024 · 1. Translation: Translation refers to moving an object to a different position on the screen. Formula: X = x + tx Y = y + ty where tx and ty are translation coordinates The OpenGL function is glTranslatef ( tx, ty, tz ); 2. Rotation: Rotation refers to rotating a point. Formula: X = xcosA - ysinA Y = xsinA + ycosA, A is the angle of rotation.
