    LuaGL Bug Topic

    Please use this topic to list all functions in LuaGL that are not working (please provide an example for each problem!), or important functions that are absent.

    Deleted my old post

    gl.ColorMask doesn't seem to work. I've tried the same code in Python and it worked fine! Whenever I call gl.ColorMask, nothing renders. it's like all parameters are interpreted as 0/false.

    Re: LuaGL Bug Topic

    Retriever. Just so its here.

    glCopyTexSubImage
    glCopyTexImage

    Both above are quite important in openGL. They also seem to be missing a paramter (target) which would normally be a texture in the texturebank, or one created. Which brings me on to another important one.

    glTexImage

    That is also documented, but not sure how it would work as its also missing the target parameter?

    FBO's (frame buffer objects) would be really good and enable some nice stuff such as deffered renders to be done.

    Thanks
    Andy

    Re: LuaGL Bug Topic

    Maybe it's just me, but i think GL extensions aren't supported, i can't get them going; specifically trying to use the ARB Multitexture extension.


    Retriever2, you've always given exceptional support ( and documentation ) for a seriously great extension!

    Thanks,

    Can you give an example? And this goes to everyone: If you can build an opengl example using the functionality in the way that you think it should work, it can make fixing bugs significantly faster for me, and virtually guarantee that our definitions of "fixed" will align.

    It might even be useful for absent functionality as well.

    SEELE , ARB multitexturing deffinetly works. And is very simple to implement. Simply Activate a multitexture.

    And then us MutliTexCoords command.

    This is also all down to if you graphics card supports it. You can request a callback to all ARB extensions supported by your graphics card.

    Re: LuaGL Bug Topic

    Example for you Retreiver.

    I reattempted VBO's and ran into the issue of it locking mmf2 runtime up again, so ive quickly cobbled together a very simple VBO example that locks up if it makes it any easier.

    Script is embedded.

    Thanks

    Re: LuaGL Bug Topic

    Thanks. I will look at it soon; I have a nasty (mock) grant proposal to get out of the way by Friday first.

    Re: LuaGL Bug Topic

    For the record I've started working on this again, though currently I'm at a snag trying to get textures to render at all.

    Edit: Things are starting to pan out now. You'll now be able to specify pixel data either using static arrays, or by much richer table processing mechanisms. That is, you have very wide leverage over how you structure your pixel tables. For example you could have a 3D table of RGB triples inside columns inside rows, or you could flatten the entire thing into a single dimensional array of size w*h*3, or a few structural organizations in between.

    The new texture functions, which are now split apart into 1D, 2D, etc, take all the SDK parameters, and will respect almost every legal configuration of type and format parameters. Additionally, it will support pixel buffer unpacking, and null pointer creation. Woo.

    It'll still be a few days before the dist is updated though.
