8-bit texture problem

glTexImage2D(glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB8, info.Width,
info.Height, 0, GL_RGB, GL_UNSIGNED_BYTE, info.Data);

the second GL_RGB shouldnt have a size specifyer since the GL_UNSIGNED_BYTE is the specifyer for this.

not working. get a crash! need help desperately

what''s the crash? What does glError report? Do you really mean 8 bits per pixel, or 8 bits per channel? How many channels does it have? What are the dimensions?

glTexImage2D(...) crashes. glError reports "Invalid Enumerant". basically i am loading half life bsp file. the images in it are contained in WADs (WAD is a file format). i have a WAD loader that gives me raw image data. there are three channels (R, G and B) and the raw data i get has RGB values for each pixel in 8 bits (3 for R, 3 for G and 2 for B). glaux loads the image properly but it converts the data in 24 bits (inflates the data) and i don''t want that because if i were to keep 24 bpp data in memory i would just have 24bpp detailed image right? . neverthless, these are all the answers to ur question. if anyone else has a question then feel free to ask . if someone has already written an 8 bit texture loader (which does not contain pallete indices but actual RGB data in 8 bits) then please help me out. thanks again. its great to know such supporting ppl in the community.

What you probably have to do is, inflate it to R3G3B2 format(means not dependant on the indexed color format), then use a GL_R3G3B2 like enum(Check MSDN) and pass that in to glTexImage2D.

Edit: the constant is GL_R3_G3_B2

You might want to convert it to 24 bits anyway since it''s probably what the card is going to do after it''s loaded.
