* fix the perspective projection and add inverse xform functions.rodri2024-05-201-0/+1
|
* add a general primitive with support for points, lines and triangles.rodri2024-05-031-0/+1
| | | | | | | | also got rid of the dependency on OBJ for the entire renderer, instead letting the user load a Model from any given OBJ. this modularity will allow for other formats to be used in the same way, relying on a single, internal representation for the entire pipeline.
* add a texture sampler with nearest and bilinear routines.rodri2024-03-061-0/+1
| | | | | | pass the material reference along with the vertices. also implemented back-face culling, but it's disabled for now.
* add user-defined vertex attributes (varyings) and improve the interpolation ↵rodri2024-03-031-0/+1
| | | | code.
* lay out the grounds for a scene renderer.rodri2024-02-131-0/+1
| | | | | | also fixed an issue with cliptriangle() where an entire tri would get discarded if all its vertices were outside the frustum.
* import the new renderer and clean things up.rodri2024-01-301-2/+28
| | | | | | | | | | | | i integrated the renderer i've been developing on the tinyrend repo and got rid of a bunch of stuff that's no longer necessary. also began structuring things to fit the new interface i have in mind. there are still some artifacts with the projection xforms that cause issues with clipping and division by zero.
* use the system-wide libgeometry.rodri2024-01-261-3/+1
|
* bring flat triangle rasterization back, with some goodies for future shading ↵rodri2020-06-291-0/+1
| | | | work. add uv coordinates to the vertex.
* standalone version release.rodri2020-04-171-0/+12
