Tiny 3D Engine for SEGA Dreamcast VMU #2

A homebrew demo of my wireframe 3D engine for the Visual Memory Unit.

The VMU got an 8bit CPU that runs with 32 to 600 kHz and a screen of 48x32 pixel.

The engine can draw points and lines, handle objects of type point, line, and polyline, features perspective projection, got 16bit fixed point math, matrix multiplication and a complete matrix stack.

This engine pushes the VMU to it's limits!

is this a game console or an accesory

[TheRealRockinB]

Both. It's an accessory in terms that it is a memory cart for the SEGA Dreamcast. It's a game console, because you can put a game on it (via Dreamcast) and play it standalone.

[SonicPsycho]

You at least have to admit that it's the coolest memory card ever made.

there's a rendering of a 3d tennis court on the vmu when u play power smash 2.

@james42519 My xbox was $5, plus $5 for an AV cable and $33.13 for a new DVD drive. N64 was $40 with 7 games, PlayStation (a 7501 model) was $15 with three AV cables (one being S-Video) and a controller. Oh, I softmodded my xbox and play N64 games I don't yet have on it :D

[james42519]

@kasm279 that's good. they can be a lot of money. still think $50 is too much for a xbox. don't worry about it you will get stuff eventually. just look at thrift stores. i have nes,(new christmas)snes,(traded a $1 yoyo for it and 4 nes games)N64,($40. little high)sega genesis/sega cd,(free with games) gamecube,(free) ps2 slim,(only one bought new $130. got 2 fat free and they work) 3 dreamcast. (no hookups and 1 controller $7.50, 2 controller and hookups, $8, 3 controllers and hookups $10)

@james42519 I don't have a gamecube or PS2 (yet) but I do have an N64, PlayStation, and an Xbox. I'm expecting something a little lower than the Xbox is. I also found out about BlueSwirl, so as soon as I have a dreamcast and cables I'm set!

[james42519]

@kasm279 oh sorry this is about the 3d engine thing. not sure how you would do this but i am sure you need a dreamcast to still do it.

[james42519]

@kasm279 i hate the way youtube does stuff. what i said was in a series of replys can see by clicking on "short by thread" at top when you click on view all comments. keep looking for the dreamcast and some games. you should like it if you liked gamecube and ps2. can give links that show how the dreamcast can do better graphics then others just by the way it does them (drawing only what you can see but not what's behind other stuff off screen).you need a dreamcast to use the vmu tool blueswirl.

@james42519 Well yesterday I found a controller with VMU for $5 so I grabbed it, yet I don't have a system yet...

[dziltener]

@hokman1 But that's rendered on the Dreamcast itself. In contrast, this 3D-Engine runs directly on the VMU.
