    I've found the issue, the base value i was assigning was the offset in the indices buffer, not the offset in the positions/normals buffers. I was even (un)lucky that it rendered sometime even with so...

    I've created a test program with static data. The positions and normals of the two cubes next to each other (12 triangles, 8 vertices/normals each) are:



    GLfloat vertices[] = {
    1.00000f,...
  3. glDrawElementsBaseVertex problems with base value

    Hi!

    I'm importing some meshes using Assimp and putting them inside 3 buffers, positions, normals and indices, queueing each data after the previous one and building sets of drawing ranges indices...

    Is it possible that the offset you need to specify for the flush command is relative to the interval set in glMapBufferRange itself?

    For example glMapBufferRange has 1000 as offset and 500 as size...
  5. glFlushMappedBufferRange and GL_INVALID_VALUE

    Hi!
    I'd like to upload a bunch of vertices of meshes (simple arrays of float values x,y,z) into a single vbo. I've created a unique buffer with the total ammount of bytes needed to contains all the...

    Rendering similar camera views in one go

    Hello,
    i am implementing a radiosity processor using hemicube renderings on the GPU and i was thinking about rendering multiple camera views inside the same rendered image buffer (with different...
  7. Composing static with realtime rendering

    Hello,
    i'm creating an OpenGL scene where i'd like to mix static raytraced renderings with dynamic 3D meshes, something seen in the adventure games as Grim Fandango, Monkey Island 4, Dark Mirror,...
