Method Summary

void	initRoutine(javax.media.opengl.GL gl, javax.media.opengl.glu.GLU glu) Initialization of GL context.
void	paintRoutine(javax.media.opengl.GL gl, javax.media.opengl.glu.GLU glu) Routine responsible for GL context repainting.
void	reshapeRoutine(javax.media.opengl.GL gl, javax.media.opengl.glu.GLU glu, int x, int y, int width, int height) Reshape routine is called every time the dimensions of GL context are changed.

Method Detail

initRoutine

void initRoutine(javax.media.opengl.GL gl,
                 javax.media.opengl.glu.GLU glu)

Initialization of GL context. It's called in init-time of every GL context.

Parameters:

gl - GL commands access object.

glu - GLU commands access object.

paintRoutine

void paintRoutine(javax.media.opengl.GL gl,
                  javax.media.opengl.glu.GLU glu)

Routine responsible for GL context repainting.

Parameters:

gl - GL commands access object.

glu - GLU commands access object.

reshapeRoutine

void reshapeRoutine(javax.media.opengl.GL gl,
                    javax.media.opengl.glu.GLU glu,
                    int x,
                    int y,
                    int width,
                    int height)

Reshape routine is called every time the dimensions of GL context are changed. It usually contains projection setup.

Parameters:

gl - GL commands access object.

glu - GLU commands access object.

x - X position of reshaped canvas.

y - Y position of reshaped canvas.

width - Width of reshaped canvas.

height - Height of reshaped canvas.
