Amazing work,Congratulations !

Just a small question, the algorithms used for rendering use floating point or fixed point math ?

[haruka282]

Thanks.

This is 12bit-fixed point at arithmetic.

Geometry operation(matrix and perspective transformation),Polygon setup and shading is all.

floating point is not used anywhere.

@haruka282 what did you used as an acceleration structure, bounding interval hierarchy (BIH) or kd-tree?

Hi Haruka,

Great post! I am designing an OpenGL 1.1 (lite) compliant graphics card and would like to use this car model for testing. Do you mind sending me the model? Thanks

sure is

what the hell is fpga!!!!!!

[embeddedboards]

WoooWW! awesome work man! :)

[morgangamer22]

COOL

[heeroyui1777]

UUUUAAAAA!!!!!

AMAZING!!!!!

GREAT WORK!!!!

Rendering is made on software (Nios II) or u

made the accelerator? (sorry i dont undestand japanaese)

[jguarin2002]

How does perform the system with a raytracing renderer? I guess this is pure raster..
