   🤔 I wonder if there's any basic triangle rasterizers available as a C single header library

   And I don't mean like textures and all that bullshit just literally triangles

   Although if it did textures and stuff I guess that could be OK too

     @eniko @gabrielesvelto Parameter interpolation in 3 or just 2 dimensional space? 3 is harder because you either have a 1/Z component to compute or approximate each step, or you orient your scanouts not along a fixed axis but lines where 1/Z is constant. Or you ignore that and your triangles look like an OG PSX. 🙃

     @gabrielesvelto fixed point scanline with some kind of parameter interpolation would be great >_>

     @eniko I would have still dusted off a skill I haven't used since the beginning of this century. What do you need, float or fixed-point inputs? Z-buffering? Some kind of parameter interpolation? Do you have a preference between scanlielne or uniform rasterization?

     @gabrielesvelto what if you make it and I don't wind up using it? >_>

     @eniko I'm finally on vacation and I'd happily write one for you if you'd like

     @eniko @gabrielesvelto Indeed. Actually your naming it that way reminded me tho: you don't need it if you're doing isometric 3D. Probably not relevant, but can be for certain applications. (I always prefer isometric for CAD & sometimes for non first person games.)

     @dalias @gabrielesvelto I think perspective correctness is a nice thing to have
