Drawing stripes on a mesh? #177

Open r03ert0 opened 6 months ago

r03ert0 commented 6 months ago

Hello!

Question 1. Is there some code around that I could use to see how to draw stripes (computed using computeStripePattern and extractPolylinesFromStripePattern) on top of a mesh in polyscope?

Question 2. Is there a way of using computeStripePattern in a tetrahedral mesh (i.e., stripes on the the whole volume, not only the surface)

Thank you!

cheers,

roberto

Hey Roberto,

  1. The extractPolyLinesFromStripePattern() gives you set vertices and edges that you can then register as a curve network in polyscope using something along the lines of polyscope::registerCurveNetwork("my stripes", vertices, edges) where vertices and edges are what's returned from the extract polyline function.

  2. Currently there is no (public?) implementation of computing stripes on volumes in geometry-central.

Cheers, Rahul
