opengl redbook

[Samuel]

after wasting a lot of time googling and yahooing i still havnt found a website where i can download the opengl redbook. i did find one very dodgy place that cut me off halfway through the download. twice. does anyone know where i can download it???

[Bugdude]

Correct me if I'm wrong but I'm pretty sure that the OpenGL Redbook has to be purchased.

[Samuel]

wrong, i found it in the end, sorry if i wasted anyones time.

or maybe this is an illeagal copy . . . . . .

I'm at odds with this. The original is available for free online (or at least was) legally, but was apparently unfit for download and offline browsing. You needed to be online in order to read it. So this person stripped out all the graphics and extras, leaving just the HTML, and made it available. Now, fundamentally, this violates copyright, since it's a copy without permission, but is it actually "illegal" in the sense that we could get in trouble for it being posted?
It's out of date, at any right. Try here:
http://www.opengl.org/documentation/red_book_1.0/
can be downloaded in PDF or HTML format.

A link to it is also in the Tutorials section of C++ Home!

Samuel: Why would want to go to the dark side ?
use DirectX

Whats wrong with the dark side? I prefere openGl because the DirectX package is somthing like 200mb. (i have dialup)

btw Is the "camera" fixed in directx? eg do you have to rotate the world in the opposite direction give the impression that the camera is turning

OpenGL and DirectX have no concept of the camera, so it's all matrix transformations.

OpenGL has gluLookAt.

For the record: I endorse OpenGL and not using DX.

For what it's worth, I suggest learning both, but using OpenGL.

GLU is the OpenGL Utility Library, I'm pretty sure DX has its equivalent.

For what it's worth, I suggest learning both, but using OpenGL.

I cnocur with the learning both part, but differ with the suggestion to use OpenGL; I recommend that you use which ever is appropriate for the situation.

[Samuel]

what is the difference between OpenGl and DX anyway? i have heard comments like OpenGL has better graphics but DirectX is faster, is this true?

[Wizard]

I recommend OGL over DX on the basis that OGL has a more C++ feel, while DX has a C feel to their respective code. I could probably be more specific, but I can't think of how right now.
And directX does tend to be slightly faster, but only because it's more quickly integrated at the hardware level in graphics cards. For example, nearly all DX functions might be implemented directly on the vidcard hardware, while only half of the OpenGL ones are. That's the usual, from what my graphics prof explained, but with OGL2, it's beginning to change the other.
As per better graphics, not that I've noticed. Everything that can be done in DX can be done in OGL, I think, it's just a matter of how complicated it is.
