So Far i was using this method in VEX to measure a thickness value, blur it after but as i could see some inconsistency, im looking for a more precise methods without having to do a render/baking…

Below is my actual code. Any suggestion for improvement?
Cheers

Measure Thickness

————————–

vector dir = normalize(@N) * -chf(“rayLength”);
vector hitPoint;
float hitu, hitv;

int ray = intersect(0, @P + dir*0.01, dir, hitPointt, hitu, hitv);

if(hitPt != -1)
{
f@meshThickness = distance(@P, hitPoint);
@Cd.r = f@meshThickness;
}
else
{
f@meshThickness = 0;

what a tease! was just looking for some thickness mapping solutions!

Use a vdb?

Hello,
There is a new calculate_thickness in the SideFxLabs (release 18.5.624)
