targetFramebuffer

protected int[] targetFramebuffer

AbstractDepthPeelingAlgorithm

Method Details

saveTargetFramebuffer

protected void saveTargetFramebuffer(org.jzy3d.painters.IPainter painter)

Remember the framebuffer and draw buffer the algorithm must render the final image to.

bindTargetFramebuffer

protected void bindTargetFramebuffer(org.jzy3d.painters.IPainter painter)

Bind the framebuffer the algorithm must render the final image to.

checkFramebuffer

protected void checkFramebuffer(org.jzy3d.painters.IPainter painter,
 String name,
 int width,
 int height)

Verify the framebuffer currently bound can be rendered to. A GL implementation not supporting the format of one of its attachments would otherwise silently render nothing.

Throws:

IllegalStateException - if the framebuffer is incomplete.

bindTargetFramebufferAndDrawBuffer

protected void bindTargetFramebufferAndDrawBuffer(org.jzy3d.painters.IPainter painter)

Bind the framebuffer and draw buffer the algorithm must render the final image to.
