---- Reported by raverboy 2004-04-27 11:44:18 ---- In order to get around various artifacts caused by failed pixel ownership tests, I render my offscreen textures to a pbuffer instead of to the framebuffer. This now works correctly on Windows and Linux with 1.1 beta 2, but on Macintosh I get on opengl error 1282 (invalid operation) when I try copying the buffer to a texture. If I've read my docs correctly, 1282 should only happen if I do the copy within a begin/end (I'm not), or if the texture hasn't been initialized (it is). - The line of code that causes the error: gl.glCopyTexSubImage2D(GL.GL_TEXTURE_2D, 0, 0, 0, 0, 0, 256, 256); - The full test case source code: http://www.wurmonline.com/newclient/PBufferTest.java - A JNLP to the test case: http://www.wurmonline.com/newclient/pbuffertest.jnlp ---- Additional Comments From kbr 2004-04-29 14:58:36 ---- It looks like the Mac OS X pbuffer support was never tested. The code has been rewritten and the attached test case now runs properly (though slowly -- not sure if this is a bug in the new code or the GeForce 4 MX I'm running with). The HWShadowmapsSimple and ProceduralTexturePhysics demos still don't work, but I haven't had a chance to look into why. Problems were expected with these demos because of differences in supported extensions between the Mac OS X NVidia OpenGL drivers (which Apple provides) and the Windows and Linux NVidia OpenGL drivers (which NVidia provides). I'm closing this as fixed. Please open a new issue if there are still problems, including performance problems. --- Bug imported by sgothel@jausoft.com 2010-03-24 07:46 EDT --- This bug was previously known as _bug_ 79 at https://jogl.dev.java.net/bugs/show_bug.cgi?id=79
