gotta love Z-FIGHTING....*cough*

ok, i hate Z-FIGHTING, lmao, now, for some reason....i've noticed something

in my redraw code, i was setting up the view like so:

Code:

gluPerspective(45.0f,(GLfloat)width/(GLfloat)height,0.1f,300.0f);

and that was giving me a hubbada lot of Z-FIGHTING when i got too far from something....

then, i changed the code to this:

Code:

gluPerspective(90.0f,(GLfloat)width/(GLfloat)height,0.1f,300.0f);

and now it miraculasly.....wow, horrible mis-spelling....got rid of all the Z-FIGHTING!!!

but, the thing is, now, whenever anything nears the edge of the screen, it looks like it's the Voyager going to warp 9, and it stretches out.......

so, is there ANY way to get rid of those Z-FIGHTING, and not have to have distorted edges of the screen?

>ok, i hate jaggies, lmao, now, for some reason....i've noticed something

its called aliasing.

because all that accomplished was distorting your view.

Anti-Aliasing.

anyways, arg, i'm sorry, i said the wrong thing. *smacks head*

i didn't mean jaggies

i meant Z-FIGHTING....

sorry, maybe that'll make a bit more sense.....

I had the same problem. I changed my depth buffer from 16 to 32 bits.

Code:

static PIXELFORMATDESCRIPTOR pfd= // pfd Tells Windows How We Want Things To Be { sizeof(PIXELFORMATDESCRIPTOR), // Size Of This Pixel Format Descriptor 1, // Version Number PFD_DRAW_TO_WINDOW | // Format Must Support Window PFD_SUPPORT_OPENGL | // Format Must Support OpenGL PFD_DOUBLEBUFFER, // Must Support Double Buffering PFD_TYPE_RGBA, // Request An RGBA Format bits, // Select Our Color Depth 0, 0, 0, 0, 0, 0, // Color Bits Ignored 0, // No Alpha Buffer 0, // Shift Bit Ignored 0, // No Accumulation Buffer 0, 0, 0, 0, // Accumulation Bits Ignored 32, //Depth buffer 0, // No Stencil Buffer 0, // No Auxiliary Buffer PFD_MAIN_PLANE, // Main Drawing Layer 0, // Reserved 0, 0, 0 // Layer Masks Ignored };

that's really strange, it worked for me. how far are the objects causing jaggies.

EDIT:
I don't know if you noticed but I've been using your model jverkoey. I won't use it if I do an 'official' release or if i bring my game to the NYL forum, but I have included it with my project a couple of times (I mentioned that it's your model though) when posting it on this board

The reason for that is gluPerspective takes the field of view Y so therefore to have 90 degrees horizontal field of view you need 67.5
