well just another test, this time ussing locke's MGS VR misions meshes.

These are zbufferedtextured poligons.

The controls;
a,b distance to snake
L,R more/less snakes
stick rotate

If at startup you move the stick or push abutton it will run on 133 else it will start at 166mhz in 3 secs

Here it is View attachment 182

Excellent !

no lightning ?

Thor

Thanks!!
Sorry no lighting this time, this was intended to be only a reallity check to see how many textured poligond could handle the engine, infact Its restricted to only one texture :) but I wante to hace some numbers to check aganist the poligono count os psx1 games...

Ah, so you're planning to make a PSX emulator? Hmmm? ;)
Not really, only thinkig on beeing able to do psx1 like games, or remakes of existing ones. Psx emulation is not only polgon drawing.

File format with texture ?

nbv
nbt
nbv*(x,y,z,u,v)
nbt*(a,b,c)

?
num_vertex
num_poligons
num_vertex*(x,y,z) fixed16.16 in centimeters
num_poligons(a,b,c)
num_vertex*(u,v) fixed point, you have to multiply u,v by textureSize and v=1-v (3ds coordinates)

Are you doing this with floating point or fixed point math?


yes that's what i was wondering too.no,actually i have no idea what that means
:)

1.347 is a floating-point number
1347 is not

dunno... looks a bit fixed-point to me :p

Actually, if you used 16:16, then the float 1.347 would be 65883 as a fixed point number :p

Also, the second are a hell of a lot easier to for the processor to handle, and so a lot faster, but do roughly the same job :)
