    Re: UV Coordinates import from 3DS mesh file

    Generating vertex normals will indeed smooth things out. For each vertex, average the normals of all faces that share that vertex.

    Re: size of normalization cube map

    Thanks for the input. After some more experimenting last night, I noticed that the artifacts definitely vary based up on the surface. Thanks for the mention of the Nvidia paper, I'll go look for it...

  7. Re: glDrawArrays crashes when fed more than 703 vertices?

    It sounds like your vertex array only has 703 elements in it. Do you know how many vertices you are trying to draw? How are you setting up your VertexPointer?

    Re: Invalid Vars Passed to OpenGL

    I'm no expert, but it looks to me like you've got a few things wrong there. First of all it appears you're drawing a vertex array per face, that's got to be a bad idea.

    Second, I think you've got...

    Also, those tutorials are simplified, for beginners to use to learn. You can process the data however you like to use vertex arrays, VAR, VAO, etc.

    As for performance, I've personally seen a...

    Just wanted to clarify so cosmicGirl isn't mislead: the current matrix is copied onto the stack, not the identity matrix.

    Yup, your program also ran fine for me. The lowest framerate I saw displayed was 191 fps.

    When he says ARB2 he's refering to the third code-path for the R300 described in the first paragraph you show.

    Re: Texture wrap question

    How about using glCopyTexSubImage to create a new texture out of the larger texture? This would allow you to tile, mirror, etc.

    Edit: Granted, this takes away the benefit of having many textures...

  22. Re: how change a file .MAX in a file .ASE with 3d studio max ?

    You are correct, when saving a file the default extension is .max. However when exporting, I believe the default is .3ds, which was the point of my comment above.
  23. Re: how change a file .MAX in a file .ASE with 3d studio max ?

    I think File->Export should do it, just change the filetype from the default (I think 3ds) to ase. If Export doesn't do it, try a Save-as.
  24. Re: how can i read in a 3d studio max file to use the object in my open gl program ?

    If you had visited the link given above, http://www.gametutorials.com you would have found that they also have an ASE loader.

    There are also lots of other examples of ASE and 3DS loaders...
