I ported (partially) my view3ds app for MenuetOS. For now it support several displaying models, please use SPACE key for switching, also make random lights (use TAB) and zoom in/out (use +/- keys).
Until them, enjoy... Cool

win3ds01 - I added several sse4.1 optimizations (using "pblendvb" instruction). When you haven't sse4.1 machine you can use sse2 version but it slower than completly unoptimized x86 code ("maskmovdqu" instruction I used to, operates on non temporal variables). I added viewing edges only drawing model, which plots smooth shaded wire-frame. All without OpenGL touching.

Win3ds02. I added ability load external .3ds file. (App open dialog at start). I implemented on/off motion blur option (press F1 key) and play with float Zbuffer coordinates also using AVX instructions -> flat shading, last drawing model; but it decreases app speed Crying or Very sad

app:

Win3ds03. I added new displaying models based on textured lines (Press space several times). Texture can be like in environment mapping or red-white stripes like in texture mapping displaying model). I added also predefined 3d model as an alternative to model loaded from file (switching beetwen models after hit F2).

Good work ! I know how not easy to write such code.
Be stubborn and believe in yourself !
You can write an article on how load 3ds model.

3ds files support added Madis Kalme in former times. This code take only a few lines. You can analize the win3ds.asm file. Not whole. Only, as I wrote, a few lines. (about 30-40). ...and thanks for your opinion about app.. Cool

It's stuff like this that makes me wish I had a CPU with AVX... Crying or Very sad

Looks amazing though Cool

AVX version is not so fast like you expected, its rather slowly than sse2 version. It was only first try Smile

how about texture? When support textures ?
Best way to direct you work to ray tracing and global illumination.
Because video cards very fast display 3d models and textures.
But raytracing helpfull on CPU witch AVX or SSE4

Win3ds04 can produce images like this:

I implemented bumps map texture dependent, fixed bug badly textured lines, plain lines without z coordinate interpolation (code posted some time ago by PabloReda) etc...

try to use shaders ...
also cuda implementation will be great ... also clean your code ... (sorry about this ...)

Thanks for your replies. Unfortunatelly my hardware don't suport CUDA. Also using shaders is for me rather difficult, any example ?

I added editor wich produce solid object using rotared bezier curve. Result is displayed on fly. Editor mode avialable after pressing F2 key several times.
