Example 1
private static void viewOrtho(GL gl, int width, int height) {
    gl.glMatrixMode(GL.GL_PROJECTION);
    gl.glPushMatrix();
    gl.glLoadIdentity();
    gl.glOrtho(0, width, height, 0, -1, 1);

    gl.glPushMatrix();
    gl.glLoadIdentity();
}
 
Example 2
private void render41x41(GL gl, int width, int height) {
    // FBO1/blur on FBO2
    renderBlur(gl, width / 8.0f, height / 8.0f);
    // Add on screen
    gl.glPushMatrix();
    gl.glTranslatef(0.0f, -height * 7.0f, 0.0f);
    renderAddTextureOnScreen(gl, width * 8.0f, height * 8.0f);
    gl.glPopMatrix();
}
 
Example 3
