Start image rendering Populates the piet-gpu subdir, with an extremely simple renderer. The main program saves the image to a PNG. Contains a few fixes (I was confused about the need for multiple bindings, as opposed to multiple descriptors within a binding). 2020-04-17 07:04:40 +10:00			`# Build file for shaders.`

Render circles WIP 2020-04-18 09:01:37 +10:00			`build image.spv: glsl image.comp \| scene.h`
First draft of kernel 1 Output of kernel 1 is validated by simple inspection, next step is to wire it up properly. 2020-04-21 10:15:36 +10:00
Encode stroke in scene This just adds the first step of polyline stroking, which is adding it to the scene. Also just a bit of cleaning up of dimensions into one header file. 2020-04-25 06:06:47 +10:00			`build kernel1.spv: glsl kernel1.comp \| scene.h tilegroup.h setup.h`
Add first draft of kernel 3 A fairly simple approach, but it adds the translation (not tested yet in scene encoding) and does bounding box culling. 2020-04-22 10:55:17 +10:00
Implement stroked polylines This version seems to work but the allocation of segments has low utilization. Probably best to allocate in chunks rather than try to make them contiguous. 2020-04-29 04:02:19 +10:00			`build kernel2s.spv: glsl kernel2s.comp \| scene.h tilegroup.h segment.h setup.h`

Fills Adds fills, and has more or less working tiger render (with artifacts). 2020-05-01 10:06:01 +10:00			`build kernel2f.spv: glsl kernel2f.comp \| scene.h tilegroup.h fill_seg.h setup.h`
Add draft kernel 4 Render from ptcl rather than original scene. 2020-04-22 12:30:14 +10:00
