Hi guys, maybe a silly question, but I can’t figure out how to fill a Delaunay object created with the mesh library http://leebyron.com/mesh/ Do I need to convert it into a PShape? Any idea? :slight_smile: Thank you!

Hi. From looking at that link you provided I would think the easiest way is to use getRegions() getRegions() returns an array of MPolygons, the order of which correspond to the order of the points entered. MPolygon contains the points of the polygon, and can be drawn to the stage. But you nee…

Thank you MxFxM, but to me it seems like a waste of computational power… is this the only way? Can I get thos array of point and in same way buil a shape or use it for something?

Hi @BrokenCode , I’m not really familiar with Lee Byron’s “mesh” library but here is my two cents: getRegions() only work with Voronoi objects the “Triangulate” library seems more appropriate in your case You just need to: download it here import it in your sketch In setup() put all th…

Thank you for your answer… I’m currently using JAVA and not Python, I can’t understand how to use this: beginShape(TRIANGLES) for t in triangles: fill(random(255), random(255), random(255)) vertex(t.p1.x, t.p1.y) vertex(t.p2.x, t.p2.y) vertex(t.p3.x, t.p3.y) endShape() Where did yo…

[image] BrokenCode: Where did you taken triangles from? triangles is the instantiation of Triangulate.triangulate(plist) It is an array list containing the vertices of every triangles

Yes! I did it! :smiley: For future usage: import org.processing.wiki.triangulate.*; int numPoints = 10; int dimension = 200; ArrayList<PVector> plist; ArrayList<Triangle> triangles; void setup() { size(600, 500, P3D); plist = new ArrayList<PVector>(); triangles = new ArrayList<Triangle>()…

I don’t understand, what’s the point of using a double for loop here ? You could draw the triangles in setup() instead of calling beginShape() at every frame. Also P2D would be more appropriate if you’re not planning to work in 3 dimensions.

Duble for loop was used in the previous vers, because I was using two dimensional array, for storing points… As I can see works good even for creating random PVector, but can for (int i = 0; i < numPoints*2; i++) { PVector newVector = new PVector((int) random(dimension), (int) random(dimen…

Thank you GoToLoop, but I can’t understand how I can use that sketch to achieve what I need… I’ve got a basic functional Delaunay obj, now I want to be able to create more distinctive and separate Delaunay obj. With the mesh library was so easy: ArrayList<Delaunay> delaunayList = new ArrayList<Del…
