The dot product X*Y is the length of the projection of X onto Y.

Most often it is used to find the angle between two vectors. In graphics, normally Y is a normal vector, and the dot product is...

z = z < 0 ? 0 : z

is exactly equivalent to

if (z < 0)
{
z = 0
}
else
{

Do you have an actual reference for that? Sorry, I'm not in the habit of just taking people's recollections at face value http://www.opengl.org/discussion_boards/ubb/smile.gif

I have imported a very large VS 6 project (thousands of source files) and the only thing that didn't work automatically were the "custom build steps" (we run perl on some scripts to generate some...

And what, exactly, are you basing that belief on? Millions of things changed when you went from Mdk to RH, including video drivers, X version, kernel version, etc. etc., not just your compiler...

"the GPL site" ?

Uh... it bombs right there because TextureImageTemp is NULL.

So, like, make it non-NULL, or something.

Well, see, when the linker complains then you are getting linker problem, not compiler problems.

Linker problems are usually the result of not properly specifying the proper libraries to link...

The 50s and 60s were the Space Age.

The 70s were, uhm, a blur.

The 80s and 90s were the Information Age.

Nowadays it's either still the Information Age or the Biotech Age, depending on who...

You should familiarise yourself with the use of a "debugger", and have the debugger tell you exactly where in your program the crash occurs, what the state of the variables are, etc.

Without that...

Well, unfortunately, they seem to be linking against a different version of Mesa than I have, and they don't give out source, so, I can't run these things at all.

Sorry.

A URL as to where we can download it to try it would really help... Google keeps replacing "libpshade" with "lampshade" :P

Works for me, except I had to add -lm to the compile command-line.

This is on a Mandrake 8.3 (Cooker) system using a Matrox G450.

Are you sure you have GL set up correctly? Do the Mesa demos...

Although, there is absolutely no reason why you need this header file to do OpenGL work... something else is...

You have two options:


Add more exclamation points to your subject so that you get noticed better.

Write a WinMain function. Consult your compiler's manuals on this.

It doesn't get much faster than this (note: GNU syntax here, adapt as needed. Also note this is x86 only)

Putting on my Amazing RTS the Mentalist hat, without seeing your code, I'm going to guess you want to say "unsigned char" instead of plain old "char" in your BMP stuff.

Just a guess. Posting code...
