Hi,

Great 3d pipeline (from your reddit post, if i remember correctly, on r/chsarp)

i get an exception when checking Triangles normals.

As i'm trying to build my own 3d pipeline too, i must say i have ended with the same graphics implementation as you did : filling a bmp from a int array, with the same pixel format for maximum speed.

i have implemented a triangle rasterization based on tiles, commonly used with SIMD instructions : https://www.uni-obuda.hu/journal/Mileff_Nehez_Dudra_63.pdf

i recently discovered the Span and Memory classes, allowing us to make pixels access by lines (like Scanline in Delphi).
Slicing arrays saves some milliseconds, strangely...

i use a precalculation of startlines, avoiding one multiply by PutPixel call.
ie : if i have a 800x600 pixel array, i have a int[600] array containing the values 0, 800, 1600, etc...
that saves me some milliseconds.

i made an animator library, based on Tasks (triple buffering : clear, draw, copy), but i wonder if it really use multithreading (when compiling in 32 bits).

i successfully migrated my project from .Net Framework to .Net Core3.1, as WinForm designer is back in VS 2019 16.6.

i have not yet pushed my work on github, but seriously think about it.
