You can simply add the color to the vertexData with `vertexData.colors`

Thank You so much. the problem is how can I split the arrGeo to make three vertex data, I know it is the JavaScript Problem, But is it possible to help me to know How can I do it?

I mean, I want to make arrGeo = [[pos1], [pos2], [pos3] ] then make three vertexData with pos1,pos2 and pos3

I think it should be easier to ask on stackoverflow for javascript questions 🙂
