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...

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
app: http://macgub.co.pl/win/win3ds02.zip a few 3ds objects: http://macgub.co.pl/menuet/3ds_view/3ds_objects.tgz Last edited by macgub on 16 Jan 2022, 16:14; edited 3 times in total |

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. |

It's stuff like this that makes me wish I had a CPU with AVX...
Looks amazing though |

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 |

All textured are generated. I don't load texture from file.

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... http://macgub.co.pl/win/win3ds04.zip Last edited by macgub on 16 Jan 2022, 16:14; edited 5 times in total |

@macgub
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.

I added *.asc models support, read and write. To write current object to object.asc file press F8.
