Did you take a look at Quigibo's 3D program he uploaded with one of the updates a while back?  That might be helpfull

Yeah that one might be helpful. After all, in z80 assembly, I believe for 3D tr1p1ea did not use floating points.

*bump*
This was just really cool, and I linked to it on Cemetech, which reminded me of it.  New users might want to check it out :)

Yeah I remember that. It was kinda nice, although I wish it was finished. I wonder if an Axe version would be possible?

Probably, but when I tried to make an Axe version, I failed horribly.  There's some math that's just too complex.  I would *not* want to do perspective projection using only integers.

Yeah. I wonder if fixed points would be effective?

If someone writes a method to get the sin/cos of an angle in fixed point form...maybe.
Does fixed point division work in Axe?
Also, fixing the resolution could cause problems.

Not sure really, it has beena long while since I last looked at Axe. You would have to ask in the Axe sub-forum.

Isn't there a float{ command to allow the use of floating-point-numbers?

That's a nice program. I don't understand how his parents blocked his internet access however. Can't he use proxies to bypass this?

I know that quigibo made a 3D rotating cube a long time ago in Axe for a demo, so I know its definitely possible :)  Maybe I'll take a stab at it, as I messed around with 3D many times in my java excursions

He was ungrounded after this was posted, but then he got grounded again and again. He can somehow manage to sneak in anyway, now, though.

Ah, but the 3D cube isn't perspective projection.

So it must be an orthographic perspective. What formula are you using btw because those matrices slow you down unless there is hardware support for them like directx.

List of stuff I need to do before September:
1. Finish the Emulator of the Casio Prizm (in active development)
2. Finish the the SH3 asm IDE/assembler/linker program (in active development)
3. Create a partial Java virtual machine  for the Prizm (not started)
4. Create Axe for the Prizm with an Axe legacy mode (in planning phase)
5. Develop a large set of C and asm libraries for the Prizm (some progress)
6. Create an emulator of the 83+ for the Prizm (not started)
7. Create a well polished game that showcases the ability of the Casio Prizm (not started)
