-## low poly chains via raymarching
+# rasterized ray marching at scale
 11 Jun 2025
 
 I've long had the dream of creating high resolution chains on characters with
 raymarching. The problem is that Unity's object transform is based on the
 character's hip bone, so making raymarched geometry "stick" to characters

+The idea I've been toying with for a long time is to raymarch inside a
+rasterized box. If you store information in that box's verts, you could do a
+raymarch inside a wholly self contained coordinate system.

+I've pulled this off, but not in a way which is useful for characters.
