WebJOGL - Rotation. 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. http://duoduokou.com/cplusplus/30792266922936389508.html free people white western boots
