Re: [gl4java-usergroup] rendering to offscreen buffer?

[Robert A. W. <raw...@mi...>]

Have you looked for anything like a QuadBuffer, SwapBuffer, or
QuadSwap?  BufferedImage definately sounds like a reasonable buffer name,
but I would suggest looking around for any keywords on
Quad-Buffering.  Moreover, you might want to take a gander at
Stereographics.com's developer program.  Typically, there is a double
buffer as the OpenGL/Java3D/GL4Java gets the images ready for
rendering.  Only, there are two threads of OpenGL/Java3D/GL4Java going at
a time (Left & Right), so there are _four_ offscreen buffers that are
drawn before the image gets 'shown' on the screen.
  Specifically, I would look for any references to quad, pre, post,
double, swap, image, buffer, and so forth.  Sorry, I don't have the
GL4Java specs on hand, but I've worked with the Java3D and OpenGL stuff...
