jitter 3d model large polygon count problem

    Feb 14 2013 | 2:21 pm
    hi, for a installation i have to make an obj/stl 3d model loader and player. My problem is, that the object has 1mio polygons. After loading them into the gl model, i see the object on the window but then max hangs each time. What is the maximum polygon count that i can use? Or is there any way to increase the memory? I can't reduce the polygon count of the object, this its needed for the installation. i have an mbp from 2011. thanks in advance.

      i forgot to mention that the .stl file size is about 100mb.

      there's a few things you can try. are you reading in the file while the renderer is being banged? you can try turning off the render qmetro, read the file, bang the render *once* (this causes the opengl structures to be built), and then turn the metro on.
      you can try changing the @mode attribute to vbo or displaylist.
      you can try enabling or disabling various file processing options: find_instances fix_normals gen_normals gen_tangents optimize
      let us know if any of that helps.

      Thanks Rob, your suggestion with the bang before starting the metro works, also the changing in the mode is working. many thanks.
