shapes is a package for Ebitengine (the 2D game library written by Hajime Hoshi) that allows rendering some common shapes and effects in complementary ways to the official vector package. Some examples:
- Smooth triangles, hexagons, ellipses and rects (all with the option of rounding).
- High quality image outlines, expansions and blurs.
- Simple patterns like dots, rhombuses and triangles.
- Some color functions and gradients.
Unlike vector, shapes relies more on simple Kage shaders instead of raw triangles rasterization. This means rendering tends to be smoother, but extra care has to be taken as changing shaders or some of its parameters will break batching.
