WebFeb 9, 2024 · The glTranslatef function produces the translation specified by ( x, y, z ). The translation vector is used to compute a 4x4 translation matrix: The current matrix (see glMatrixMode) is multiplied by this translation matrix, with the product replacing the current matrix. That is, if M is the current matrix and T is the translation matrix, then ...

In this chapter we explained you how to rotate an object using JOGL. Rotation of objects can be done along any of the three axes, using the glRotatef (float angle, float x, float y, float z) method of GLMatrixFunc interface. You need to pass an angle of rotation and x, y, z axes as parameters to this method. hallway trim ideasThe glRotatef function computes a matrix that performs a counterclockwise rotation of angle degrees about the vector from the origin through the point (x, y, z).
