Hello,
artist trying to learn math here.
what is parametric uv?
is it describing coordinates using a function with two parameters u & v?
so it nothing to do with uv's (as in texturing)?
also does prim_attribute vex function find the point nearest to the parametric position (by distance?) to get its attribute?
thanks
J

hello, is there anyway I can read these intrinsic UVs of the points in a vex wrangle?
I can't seem to find any functions that returns it.
parametric uvs are not property of points, but primitives of certain types
so if there are more primitives attached to a single point it may be different uv per primitive so not a single uv value per point
in simpler cases like curves you can for example use xyzdist() to sample the paramteric uv on the curve the point belongs to
