The problem w/ the demo code is that it does not use a VBO buffer (AFAIK), and this is illegal for core profiles - at least starting w/ GL4/ES3. Following 'runs everywhere' philosophy requires users to to patch their code, so it runs on most core profiles. The 'real' bug here is IMHO the lack of handling this case in our code, i.e. throwing an exception that no VBO was used on an VBO only context. Hope it makes sense .. (In reply to comment #9) > The problem w/ the demo code is that it does not use a VBO buffer (AFAIK), > and this is illegal for core profiles - at least starting w/ GL4/ES3. -> GL3/ES3 core profile, that is. OK i understand, according to the JogAmp JOGL spec the code is correct: "GL2ES2 The intersection of the desktop GL3, GL2 and embedded ES2 profile" https://jogamp.org/deployment/jogamp-next/javadoc/jogl/javadoc/javax/media/opengl/GLProfile.html#GL2ES2 Its the intersection of GL3 makes GL2ES2 only guarantee to work with core functionality/use; and this removes the backward compatibility assumption that the demo code relied on. The naming GL2ES2 may be confusing for new users, like myself, who expect it to only include the intersection of GL2 and ES2, like i was assuming when writing the demo code. I will update the demo code to stay compatible with the current JogAmp JOGL spec. https://github.com/xranby/jogl-demos/commit/84a886cf4957e8f55af39abf8e9bad04a1de2e4f Fix bug 821: RawGL2ES2demo: Use VBO buffers and update shaders to stay GL3/ES3 core profile compatible.

Me too .. i.e. awareness of VBO only since GL 3.1 core was earned only a few month ago. Enhancements: A) Throw exception if using a 'pointer/array' method w/o VBO and core profile! B) Remove the array/buffer variant from all core GL profiles, i.e. only provide the VBO offset ones. (A) is easy to do .. (B) will be a good API change .. which we can add for 2.1 (next version/release) ? https://github.com/xranby/jogl-demos/commit/594cba9b34faf0ef2f0f7bf7801c2b228984b02a Fix bug 821: RawGL2ES2demo: Explicit add #version 130 for GL3 core & release VBO using glDeleteBuffers. Signed-off-by: Xerxes Rånby <xerxes@zafena.se> This commit adds support for AMD OpenGL 3 & 4 drivers that have deprecated the implicit GLSL version 1.1. Explicit add #version 130 to the shaders if gl.isGL3core() Release of VBO prevents running out of GPU memory using the NVIDIA Tegra 2 drivers.

I agree A and especially B is good enhancements, makes the API clear and forward compatible. B guarantees that applications stay inside the GL2ES2 spec using compile time checks.

Of course, no intention to remove existing functionality.
I will create a new bug report to tackle this issue properly
w/ reference to the spec.
Bug 852 tackles the API issue and it's runtime validation. *** Bug 260998 has been marked as a duplicate of this bug. *** Seen live from the domain http://volichat.com/adult-chat-rooms Marked for reference. Resolved as fixed @bugzilla. |
