Hi  
I am not sure what you mean but look at this

> Hello all, the reference has Quad\_Strip, but only for one line of quads. How can I make a bigger grid of QUAD\_STRIP? Actually, the main problem is the line break at the end of one line in the grid. I don’t want the right side to be connected with the left side of the next line in the grid. Part of a MUCH bigger project, but here is an example. As you can see, the values are in MyResults, which is a 2D array (grid) of PVector. I struggle with the vertexPV() command . Or do I have to say en…

> Hi @Chrisir , I would just use QUADS. int resolution = 32; PVector[] points = new PVector[resolution \* resolution]; color[] colors = new color[resolution \* resolution]; float scale = 250.0; void setup() { size(720, 405, P3D); int len = points.length; for (int i = 0; i \< len; ++i) { points[i] = new PVector(); } } void draw() { surface.setTitle(nfs(frameRate, 1, 1)); background(#202020); perspective(PI / 3.0, -width / (float)height, 0.001, 1000.0); camera( hei…
