    hi i am using a pvr SGX chipset and am running a sample application to test opengl 2.0 compliance. a part of the application is to read a triangle mesh for a terrain and other objects which are then rendered onto the screen. what i see is an incomplete mesh as in there are lots of triangle which appear to have not gone through the gl pipeline.

    i have used lots of glFinish() calls just to ensure completion of pipeline and then a swap buffer but without results.

    the logs gathered during the application showed one line consistently:
    “OSEventObjectWait: failed [1634, osfunc.c] TLSId:70
      PVR:(Error): PVRSRVEventObjectWait: Error 6 returned [522, ../../../../services4/srvclient/env/nucleus/common/osfunc_um.c] TLSId:70
     PVR:(Error): WaitForRender: PVRSRVEventObjectWait failed [106, sgxif.c] TLSId:70″

    any suggestions as to what might be the problem and possible solutions.
    i am not working in a multi-threaded environment.

    thanks a ton…..

    Which platform are you using and which version of the drivers for that platform?

    How are you submitting your geometry – what vertex format are you using, are you submitting strips or lists etc.?

    we are using a proprietary platform on a mobile. vertices are of the type GL_FLOAT. we are using indices to create the geometry. GL_TRIANGLES is our basic and only primitive. there is a vbo that contains all data including vertices, tex coords, normals and so on. glDrawElement is used to render the mesh.
    driver version in use – DDK 1.4 (2724)

    This looks like it might be driver problems with your platform.

    For us to support you properly can you send an email to devtech@imgtec.com so the relevant people can talk to you directly, please?
