Thread: clipping triangles.

hello im new to this forum so please bear with me,
i have been looking for some help on clipping triangles,everything i have found is written in c,and i dont use c myself,but i know that c can make lib for qbasic,hence why im here,if anyone would be able to help me,please do,i have lots of links for c code that clips the screen properly,and i just need it made into a qb lib? is that possible? alls that i need is the triangle points moved ,and maybe i would be able to use the result of the percentage clipped to do the math for the texture source clip. ive already posted for help in other forums,and most people dont have a clue what im talking about!!! hehehe

It's not hard to implement a simple clipping algo (even in qbasic id assume). Look up the Sutherland-Hodgeman clipping algorithm (yes, algorithm, not C code) and start from there.

thanbks perspective,i looked it up but could only find c code for it

C can be used for that but not the ones mentioned under the compiler list on the main page of this site. The only version of C I know of that might be able to do this is Microsoft Quick C.

My advise to you is to drop QBasic. Don't take this as a "QBasic is crap and sucks switch to C" bit of advise, I used to use QBasic constantly and I know it is a fairly decent language for being 16-bit and DOS. The reason I say drop it is that you aren't going to get very far with 3d graphics in it for a number of reasons with the two biggest reasons being speed and memory limitations.

If you're switching from QBasic I'd recommend MinGW. The reason is that it is command prompt and, as it always seems to be, QBasic people are good with the command prompt. The tutorials on this site are okay but not the greatest so it'd probably be best to check a library or bookstore for a book of some sort (I personally used "The Complete Idiot's Guide to C++" and I also used one of the Sams 21 days books).

well if your interested in what i have done,ive made a game,fps,full modeling,sorting,ect,ect

heres the links

i know all about qbasic probs,ive used basic for like 20 years how can i switch to something else when i can program with qb while im sleeping!!!!! hahahha

if you can program basic that well then c would be a breeze to learn and you would never look back.
