Gave it a test and it runs really nice so far!

thank you a lot !

by searching on net some algorithms to create illusion of sorted polygons, I found the usually z-buffer but it's seems that there is a lot better algorithms for speed : s-buffer (and it look like it's work with line of polygones, exactly the way I render them)
the problem is that I don't really understand how it's work (maybe my english level is too slow  ;D)

Yet, I think I found a good tuto :http://www.gamedev.net/page/resources/_/technical/graphics-programming-and-theory/s-buffer-faq-r668

so if anyone can help me ?

Hey, what version of AXE do you use to compile this? I'm using 1.2.1a, and I'm getting black screens at different locations.

Pretty impressive work so far TheMachine :D Looking forward to some more implementations of other textures and clipping

Im not sure the calc has enough memory to constitute a z-buffer or s-buffer. The way i usually do it is to sort each polygon by average z-value if that helps.

it's axe 1.2.1a. That strange you have black screen (can I see a screenshot please ?)
(errr.... don't forget that the plolygones are render with black shapes...)

Im not sure the calc has enough memory to constitute a z-buffer or s-buffer. The way i usually do it is to sort each polygon by average z-value if that helps.
The big problems of this methode I haven't succed to create a fast sort routine ; and because I just can't sort it by the way I render things.
That's why I was looking for something else.
(and as I have understand of s-buffer, it's not taken so memory (but maybe I'm wrong))

This Happens when I turn right (just one triangle supposed to be on the screen):

A black bar appears randomly!

That's all good, its just because he hasn't finished the clipping on the triangle routine yet.

Yeah, it seems to be a clipping issue as it only happens if you go off the screen.

yes ; it's just a clipping issue due to axe numbers.
I will try to fix this soon  ;D

A litlle update :
GREYSCALES and faces definitions (you can choose the color of the face !)

3 levels greyscales and I reduce the size from nearly 4000 bytes to 3000  :thumbsup:

Looking at the screenie, I see that the grayscale is a bit different when changed

I suggest using Pt-Change()r

In case you are wondering where I went, I left Omni back in 2015 to form CodeWalrus due to various reasons explained back then, but I stopped calc dev in 2016 and am now mostly active on the CW Discord server at https://discord.gg/cuZcfcF
