CF_VertexFn¶
Category: draw
GitHub: cute_draw.h
An optional callback for modifying vertices before they are sent to the GPU.
Remarks¶
Setup this callback to apply per-vertex modulations for implementing advanced graphical effects.
Count is always a multiple of three, as this function always processes large batched arrays of
triangles. Since all shapes are rendered with signed-distance functions, most shapes merely generate
a single quad, so you may find triangle counts lower than originally anticipated.
Call cf_set_vertex_callback to setup your callback.
There is no adjecancy info provided. If you need to know which triangles connect to others you should probably redesign your feature to not require adjecancy information, or use your own custom rendering solution. With a custom solution you may use low-level graphics in cute_graphics.h, where any adjacency info can be controlled 100% by you a-priori.
