Title: Which comes first: setvertexcontroller or build?
Post by: Irony on November 09, 2014, 03:50:48 pm
When I setvertexcontroller before build(), there is a warning about normals. When I set vertexcontroller after build, applyvertexcontroller seems to have no effect.
I have read and experienced some contradicting things about the topic.

Maybe it's important to mention that there is a rotateMesh call in there as well.

The best way is to call calcNormals(), then set the controller, then call build().

Works perfectly, thanks!

One related question: Why does a cube have 10 vertices and not 8?

vertices are the lines not the faces

Neither...they are the end points of the lines.

Depends on your cube. The ones creates by Primitives have 10, because they are actual lathe objects with addtional points in the center.

Yes I meant the one from Primitives. Thanks.
