WebOct 9, 2014 · Then I undo the panning effect like in the first example. However this seems to have no effect, and the coordinates are converted as if there was no zoom. In case it is unclear, the camera transformations using glTranslatef and glScalef are used at the beginning of the render function before the first glPushMatrix call. WebScaling an object is done by using void glScalef(float x, float y, float z) method of GLMatrixFunc interface. This method accepts three floatingpoint parameters, using which we specify the scale factors along the x, y, and z axes respectively. For example, in the following program, a triangle is diminished to 50%.
