2 questions
Author
Hey guys, i have 2 questions.
1)
I did the NeHe tutorial 14, and learned how to make 3d text, which is pretty cool :) How can i "fix" it to the camera so that it ALWAYS stays in one place on the screen?
2)
I have altered a 3ds loader i downloaded to load multiple 3ds models i have made. How can i do skeletal animation?
Thanks :)

Well, the easiest way i can think of would be to
render scene
push a modelview matrix,
set it to identity,
move your text into position
render text
pop matrix
(of course if your scene transform changes every frame as i suspect it does, you could instead of pushing and popping the modelview matrix, simply set the current matrix to identity and then move your text. since theres no sense in saving a state that wont be used again anyways)
i have a question for you though: Unless you have your text at a little angle so you can see the bottom of the text, whats the point of having 3d text anyways? you might as well use bitmap fonts if you ask me.
as far as the 3ds skeletal animation question goes, i'm sure there are some tutorials out there, though i gotta ask, why do 3ds anyways? there are other formats far more suited for games anyways
cheers (hope that helps)

Be patient with gamedev, it'll take some time, but it will go. You can edit/modify 2 of your posts, and in the page, you should see a delete checkbox where you can delete the post.

ok. It's working. Only problem is this - when i turn the camera with the mouse or keyboard, the text doesn't turn with it - meaning that if i turned the camera 90 degrees for example, i see the side of the 3d text
Well if you're setting the modelview to identity, and then translating your text into position (in screen space), it should stay anchored to the camera, because the translations and rotations associated with the camera arent applied
hope that helps

I think that you're rotating the camera around the text. The glLoadIdentity function will clear the current matrix to an identity matrix. Can you post some code?
