texture crash

Recommended Posts

when I load some bmps with gluBuild2DMipmaps() my program will crash and some bmps will load fine. I thought gluBuild2DMipmaps() would load any bmp and resize it. --------------------------- The pipes clangor all the time.

gluBuild2DMipamps() will load any bmp and resize it. But:
1. Your data must be valid
2. Check the width and height params you are passing to gluBuild2DMipmaps. If width*height*components is greater than the size of the allocated buffer, it will crash.
3. set
glPixelStorei(GL_PACK_ALIGNMENT, 1);
glPixelStorei(GL_UNPACK_ALIGNMENT, 1);
brefore scaling.
EDIT: You can set it to the default value (4) after scaling. When I didnt set it to 1, the image wasnt scaled correctly.
Hope this will help
