    I hate to drag this back out into the light, but I still have no idea why this isn't working, and I don't know how to debug the situation. As far as I can tell, I set up the frame buffer and texture...

    Anyone? I just need to know if the code I presented is correct so I can narrow my debugging. I'm not sure how to examine the internals of the frame buffer during real-time. . .
  4. Drawing to background frame buffer

    Hello all,

    I'm trying to get my feet wet with using frame buffers. I've set up a frame buffer based off of a number of online tutorials, but the texture that I attached to it doesn't seem to be...

    Specular light shader

    Hello all,

    I have the following function within a vertex shader that I got from "Egon Rath's Notes" on www.matrix44.com. Unfortunately, I can't seem to get it to work.

    Cool! Thanks! That should give me a place to start.

    Started the account a long time ago, then was pulled away from OpenGL for a while. . . It's changed a bit. Thanks again! :)
  8. Interesting, and good to know! Thanks! :)

  9. When is data sent into the pipeline?

    I've been coding OpenGL purely by example, and I'm at the point where I want (and need) to understand what I'm doing rather than just mimic code. :( Especially considering the project I'm working...
  10. Render onto previous frame with blending

    Hello all,

    I'm a relative beginner, but I've created a simple program where I'd like to render each additional frame onto the previous frame, ignoring the color black and all other colors are...

    The matrix is generated separate from OpenGL. For a variety of reasons, I keep a history of the transformations separate from OpenGL, for now anyway.

    I've tried looking through the posts that have already been made regarding the topic of Euler angles, but I'm not sure if Euler angles are the route to take for my current problem. My...

    glGetName?

    Supposing I use the glPushName() . . . glPopName() functions, how would I be able to retrieve the current name pushed? I need it for debugging purposes.

    Thank you.

    Re: GL_UNSIGNED_INT_8_8_8_8 is undefined

    Perhaps I'll look into the glew headers.

    I'm not sure why the glext.h file isn't working. :( I went to the website, hit "select all", "copy", and then pasted the code as-is into my own file...

    Re: GL_UNSIGNED_INT_8_8_8_8 is undefined

    I just got around to downloading glext.h. Unfortunately, we I add a file glext.h and copy all the contents of the online file into it, I get the following error:

  18. Re: A glfont that is not Windows dependent

    Rats. :( Based on what I can tell, that is what glfont2 does.
    Has anyone been able to get glfont2 to work? I really don't want to recode the entire thing.
  19. Re: A glfont that is now Windows dependent

    That's what I was afraid of. . .

    Does anyone have a working glf file, like say "timesnewroman.glf" I can try? I'd like to minimize variables in order to figure out why glfont2 doesn't work. I...
  20. A glfont that is not Windows dependent

    Does anyone know a simple way to print text using OpenGl that is not Windows dependent? I tried using glfont2, but I can't get it to work. :( What are the options?

  22. Re: GL_TEXTURE_MIN_FILT dims entire screen

    Unfortunately, that brings me back to the original state of the program. When I added:


    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);

    it causes the color of the quad to...
  23. Re: GL_TEXTURE_MIN_FILT dims entire screen

    I added the line as you suggested, elFarto, but it says that GL_GENERATE_MIPMAP is undefined. I downloaded glext.h, but my compiler insists there is a #endif mismatch in the document. :(

  25. GL_TEXTURE_MIN_FILT dims entire screen

    I've been observing a strange behavior that I've managed to capture in a very watered-down version of my program. Basically, I have the line:
