normal point center

[nilsoncardososa]

Hello, I need to create a point in the center of the primitive, this I was able to do. But now I need this point to have the same normal as the primitive, how can I transfer this information to the point.

There is a better way, I'm sure of it but this works.

center_fix.hiplc

int pt = addpoint(0,@P);
setpointattrib(0, "N", pt, v@N);
removeprim(0,@primnum,1);

or if you want interpolated N instead of geometric N

int pt = addpoint(0,@P);
vector N = primuv(0, "N", @primnum, {.5, .5, 0});
setpointattrib(0, "N", pt, N);
removeprim(0,@primnum,1);
