1. 3d gl camera
ok heres the problem, i am able to get camera fluctuations from the
program, like X points to the right or left and up or down, i am
having an extremely hard time sending these values to an equation to
get a desirable 3d camera feel. i have trawled the net and everything
out there either wants to be a class or structures and now i see a
piece of c++ code i feel like crash tackling my computer off the desk.
can any 1 suggest a simple camera translation algorithm for rotating
the camera around its own y axis and x axis i can handle the rest
thanx Joe
2. Re: 3d gl camera
i came close to the desired feel using the following code
gl_translatef({-camdiff[X],-camdiff[Y],0.0})
gl_rotatef(1.0,{camdiff[Y],0.0,0.0 })
gl_rotatef(1.0,{0.0,camdiff[X],0.0 })
it just doesn't cut it tho :(

In case you didn't see these:
http://www.cklester.com/euphoria/?eu_opengl
Also, Evan Marshall has translated a lot of NeHe's OpenGL tutorials...
http://nehe.gamedev.net/
There is Euphoria code for a LOT of those OpenGl tutorials. It's awesome.
Evan has done great work with that. Check it out!

4. Re: 3d gl camera
ok thanx for the help, i have already been thru most of the NeHe
OpenGl tuts and found that where there is a camera class involved
there is no Eu code, i think mainly due to the nightmare of
implementing classes and structure styles in Eu, not to say it cannot
be done tho. i have seen your GL stuff maybe that can help, i will
look in more detail, i dont remember seeing anything to do with a
dynamic 3d camera in there tho :/
thanx Joe

I don't even know exactly what you mean by a "dynamic 3d camera," so I
know I can't be of much help. But I know that there is camera movement
code at NeHe and on my site... let me know if you find what you need,
or define "dynamic 3d camera" for me! :)

I've been thinking about porting the camera class. Been busy writing a
board game. I need a break from it though, so maybe I'll look into the
camera.
7. Re: 3d gl camera
ill be forever in your debt if you port that class for me, i attempted
it about 6 months ago , ended in disaster and turned me off gl, is
good code if u can wrap it without losing alot of it's class features
by the way ck, by dynamic i mean free from and independant of the
gl_begin and gl_end or draw() routine, i need to be able to assign
other transforms aswell as be able to assign the cam to an object etc
etc
* prolly not the best choice of word in that case
thanx joe
