i need to use gldrawpixels to place 24 bit bmp images as backgrounds for an opengl screen. For various reasons i cannot use a quad textured for the background eben though i know it would be faster.
My problem is im loading a bmp as a resource file and can successfully get it on screen using gldrawpixels, but i have to loop through every pixel of the bmp file to create an appropriate array for passing to opengl.
Under win2000 using BCB6 c++ is there not a faster way to assign the bmp data to opengl without have to iterate through loops. It dosnt seem possible to jsut pass a pointer as the bmp windows format does not match gldrawpixels requirments
any help appreciated
