  1. Tracing and Profiling GLES on Desktop GPUs?

    Could someone point me to a list of the options for either 1) tracing (generating GL call dumps), and/or 2) profiling GLES on desktop GPUs?

    I'm most interested in solutions for Windows on desktop...

    While we're getting our wish list together, how about bindless vertex attribute and index lists? Minimizing time spent/wasted in the driver just getting ready to launch batches is even more...

    Which CL device for GL context?

    I hope this isn't a stupid question, but I'm a bit confused as to how to get "the" OpenCL device associated with a specific GL context. clGetGLContextInfoKHR() returns a list of devices assocated...
  4. Re: Sharing textures with OpenCL (avoiding glFinish/clFinish

    Thanks. Did post on NVidia's site yesterday, but hadn't yet received a response. It's possible I haven't waited long enough.
  5. Sharing textures with OpenCL (avoiding glFinish/clFinish)

    Currently to pass a texture (or renderbuffer) to OpenCL for some fast crunching on the GPU, and to pass the result back to OpenGL, I'm doing:

    Re: Read GL depth buffer from OpenCL?

    Ok, thanks. I was hoping to get out of writing a redundant FLOAT color channel, doubling my write bandwidth, just to use OpenCL for this.

    Read GL depth buffer from OpenCL?

    I want to do some post-processing on a OpenGL depth buffer with OpenCL.

    However, AFAICT, OpenCL can't do this. Is this true? If so, what's the simplest way to shim this so OpenCL will work?

    Happened to notice a while back while reading the NVidia Fermi whitepaper that it supports Concurrent Kernel Execution. This sounds like what you're...
  9. Re: Canvas 3D: can't get a native PBuffer... (firefox-3.7a6)

    Fetched the 6/17 3.7a6 snap from here, and I can confirm that a few of the WebGL Wiki Demos work now (so some improvement), but most still do not.

    Those that do work are a less jerky, but still...
  10. Re: Canvas 3D: can't get a native PBuffer... (firefox-3.7a6)

    It really looks like the older Firefox builds that work are using the NVidia driver not Mesa. lsof reveals that<nvidia_version> is linked into the firefox-bin executable. Also, I don't...
  11. Re: Canvas 3D: can't get a native PBuffer... (firefox-3.7a6)

    Very nice! Chromium WebGL is smooth (unlike Firefox 3.7a5 5/11/10) and all the demos work (also unlike Firefox). Hope Firefox WebGL improves before release as I and everyone I know are hooked on it.
  12. Re: Canvas 3D: can't get a native PBuffer... (firefox-3.7a6)

    That was the ticket. Thanks!

    Even with 3.7a5 (5/11/10) only some demos work, so I'll flip over and give Chromium a shot.
  13. Re: Canvas 3D: can't get a native PBuffer... (firefox-3.7a6)

    And if the former, how do I debug this? Thanks.

    (Sys info: webgl.enabled_for_all_sites = true. glxinfo, glxgears, and my GL apps work fine. NVidia GTX285 with drivers. OpenSuSE...
  14. Canvas 3D: can't get a native PBuffer... (firefox-3.7a6)

    Friend told me Firefox WebGL had improved, so I retried and get this for everything WebGL (e.g. particles demo):

    This demo requires a WebGL-enabled browser.

    In Error log console:
