Yes. Sorry didnt mean to put fixed 3d there.

It is very in depth math and covers many concepts of 3d that you will not be implementing in luaFX but one book that really helped me understand a lot of 3d games including optimization for specific architectures was Real Time Rendering. I highly reccomend it to anyone who wants to learn a lot about 3d

So in other words, wait until someone gets openGL on a calc. cuz i'm not going to do something that complicated. I think i'll do 2d games instead. could someone help me with the concept of side-scrollers? (LuaFX again)

Ashbad is working on OpenGL84+ somewhere Ill post a link when I find it

yeah but i need it on casio fx-98xx

I did write a rotating cube example a few months ago in Casio Basic and it was fairly simple. If you want I can upload the source and/or the program and it will run on you fx-98xx because prizm basic programs can be down converted.

yeah, but would it help me program in 3d with lua?

z80man · « **Reply #22 on:** August 30, 2011, 08:57:28 pm »

The math is the same regardless of language and if you know casio basic moderately well then it will be easy to port that example to lua. One thing you will have to add though is be able to convert plot points into screen coordinates but if needed I can help you with that part

flyingfisch · « **Reply #23 on:** August 30, 2011, 08:59:46 pm »

oh ok. is it commented?

P.S. I am pretty good at BASIC, if I do say so myself.

LFX is simply as BASIC? but more powerful.
You can use some functions like Pseudo OP...

OK. BTW: veb sent me a demo of LuaFX

Cool menu!

(...and graphics)

I assume in a language like Axe it might be harder, right, due to the lack of floating points? (Although this doesn't really apply here)

Eiyeron · « **Reply #27 on:** September 05, 2011, 06:00:28 am »

Right, but A firend made a system of emulation fixed points, faster than floating.

I know this particular thread is for Casio 3D, but does anyone have a good resource for 3D rendering on the computer, preferably in C#? My main problems with understanding 3D are how its data is stored (something like a really huge matrix seems impractical to me, unless only portions are accessed at any given time) and the rendering itself.

If I should start a separate topic, I'm sorry for interrupting this one. Just let me know and I will.

What API/Library are you leaning towards? Once you choose which path to go with, finding a tutorial is rather simple.
