yes, i know how to do it, but is it reliable? will some cards go crazy when doing glCopyxxx and so on? the reason i want to use it is drawing all my stuff in software 2d into a buffer (now doing it...

hi,
i would like to know if somebody knows about how hard it will be to "upgrade" OpenGL 1.x code to 2.0. Maybe it's necessary to completely reorganize stuff (due to vertex buffer management and so...

hi, i've got the genesis 3d engine here, i wonder if there's a port of the graphics driver to OpenGL anywhere,'cause it features only DirectX,Glide and software mode... another question: i've never...

hi,

could someone send me a simple openGL framework app ( res. switching, init code,..) for linux? i dont need special fx, just the setup would be cool...

thanks in advance,

hello!

when i turn on the polygon-smooth hint to GL_NICEST, it seems as if the hardware acceleration gets lost sometimes(not any time http://www.opengl.org/discussion_boards/ubb/confused.gif...

you have to use the openGL selection mode....this is a pain........

cool, this is funny :-)

i also get an exception thrown my way from kernel32.dll, dont know if it is about openGL,though. but my problem is i get some strange graphical errors now and then. all of...

hi,

i sometimes get an unhandled exception with the origin gdi32.dll, i traced a little bit and i think it has to do with the pixel format stuff and/or GL-RC. it's strange,because it doesnt happen...

i know this... http://www.opengl.org/discussion_boards/ubb/mad.gif

the card i ran it on is a intel 2mb, so i didnt expect HW-acceleration. but i want my program to run "fast" in software,too. (...

ok,

i like to see my little engine running on a GeForce or similar with 200 f/s in 1152*864*16 or 32 bpp mode, but when i run it on other systems( old Intel card for example), i get 1 fps maximum....

i think if you wanna do speedy OpenGL programs, do it with the Windows API, because there's very much going on behind the MFC-scene. ( message map, command handler, and in W.API you just have a...

thought i'm the only german speaking guy here.... (why do i write that in english :-) )

there's a new tutorial on gamedev.net about quaternions.it comes along with some useful code.. ( i'm really happy about that one http://www.opengl.org/discussion_boards/ubb/smile.gif...

it's just to rotate the car in the heading it should look, as you can see ...

but finally i dont wanna annoy you with my problem, think i'll heavily learn math now....

hello http://www.opengl.org/discussion_boards/ubb/smile.gif

i've coded and read some math stuff as well( i am really sad about not learning this in school for free ...

thanks, i'll have a look at it http://www.opengl.org/discussion_boards/ubb/smile.gif

hi, my 2nd question for today to keep things going on http://www.opengl.org/discussion_boards/ubb/smile.gif
i posted this question a few weeks ago, but wasnt able to solve the problem...

i have...

great!

if i have any problem now, i'm just too stupid to code openGL stuff http://www.opengl.org/discussion_boards/ubb/smile.gif

hi,

i cant manage this:

i want to draw some objects in my scene, which are partly transparent. example: a fence, a tree and stuff like that. i guess it is done like this: make a bitmap with a...

hi,

just wondering which games everyone works on(if any)...

just asking, coz i'm bored today http://www.opengl.org/discussion_boards/ubb/smile.gif

you have to make use of the gl-selection mode. there're some simple tutorials on how to use it on the web.

could you paste some code?

(short answer,huh? :-) )

hi,
you could "cut out" parts of your sprites,i.e. making parts of it totally transparent(alpha value),i think the technique is called color-keying

"its not the number of triangles so much that drops framerates but the number of state changes."

is it true? how are state changes like glEnable(GL_TEXTURE_2D) made? i always thought it's just...
