3d engine

Catalyst · **Posted:** Sun Jan 26, 2003 4:05 pm

I made this engine today (2-5), it doesnt have any textures but allows for rotation and perspective. The arrow keys move the cube around on the x and y, 1 and 2 move it on the z. To rotate use 4,6,8. It supports more than 8 points but i didnt want to spend the time to make a more complicated figure.

8) looks good

the only thing I want to be added to this is filling those sides with colors and being able to import models from 3D modeling programs as 3DSMAX Wink

I'm really behind on putting my 3D engine together cuz of school work (art is really time consuming) and I can't seem to figure out how to tell if a polygon is visible or not Confused

If someone can tell me how to do that, it'd great for the whole turing community Very Happy

i had something to say but now i don't, sorry...

Looks cool in wireframe but you should make an option for either having it wireframe or textured or just colors. That'd be even cooler but good job.

the thing with having it to fill polygons with colors... you'd have to go into Z-sorting and finding out in which order to fill them... or which polygons will not be visible. Confused

personally I donno how to do that Embarassed

if u look at the 3d editor, (i think its posted here) i made it had full vsd, using z-sorting,along with light shaders, filled polys,etc.

note: noticed didnt have to newest version up, so i reposted it

nice! 8)
hey i'm trying to make a program that can import 3dmax files do u know where i cn get the file formats from ...? and i also need bmp file format! please message me if u can help me =)

Tony · **Posted:** Sun Mar 30, 2003 2:03 pm

you can export 3DSMAX files in .raw format. Its the easiest to understand and to extract information from.

Homer_simpson · **Posted:** Mon Mar 31, 2003 5:07 pm

yes that is true Smile

But now i need to know where to get the 3d formulas from like the formulas for turning (x,y,z) coordinates to (x,y) to be drawn on 2d screen of the monitor! Can u help me with that plz?! Smile

thank u!

you have (x,y,z) right? the 2d version is simply (x/z,y/z) of course, that implies(x,y,0) as your camera angle. one workaround is to move everything to (x,y,z) for some positive z

i do not recommend 3D in turing, it is only good for a school project. if you are going for 3D, might as well go for C++ and Direct3D. much easier, and if i am not mistaken, it has a built in Z-sorting along with many others. i you can make games like freespace, why make a slow and crappy turing program is my perspective on which language to use

bugzpodder · **Posted:** Mon Apr 07, 2003 7:33 am

i guarentee you will not be program in turing after 1st year of university (UoT has the first year turing programs i think)

Tony · **Posted:** Mon Apr 07, 2003 7:47 am

lol, the only reason UoT has turing as its first year, is because Tom cant afford to pay rent, so he still lives on campus, letting university use turing...

Confused

*Tony makes up stories good* Very Happy

shoudnt tom get royalties from turing??

Tony · **Posted:** Mon Apr 07, 2003 10:54 am

royalties? the guy chargest a ****ing $80 a copy! New games cost less then that, and they actually work out of the box, not a year later with a patch.
