I have a fairly good experience in C programming using DJGPP, but now I'd like to start 3D graphics programming (just in dos window/real dos, nothing fancy). I have found a lot of info about formulae etc on how to plot 3d coordinates and how to draw polygons. Now the only thing I need to start actually writing all the functions are two basic functions: switching screen modes and plotting a colored pixel at XY coordinates on the screen. I would theoretically know how to write these functions in assembly (calling an interrupt and modifying the video memory), but are there any DJGPP functions that do these two things for me? I don't really need anything else (I'd like to learn the actual logic of 3D, not just call openGL functions)... Also, writing assembly code that taps into the video memory and calls interrupts is a risky buisness in windows... If I start a Dos program that does these two things in a dos window, wil windows manage interrupts and the like without crashing out? Thanks in advance for your help David Anderson, beginner 3D programmer
