When/how to use setVerticesData vs. updateVerticesData

[Evgeni_Popov]

updateVerticesData is better for perf when you can use it, see my answer here:

Correct/performant way to build my own mesh/geometry?

mesh.setVerticesData creates a new VertexBuffer each time it is called. So, if you have to update data each frame, it’s better to use mesh.updateVerticesDataDirectly instead. Are you calling mesh.updateVerticesData with a true value as the 3rd parameter? If you do, you should pass false, or use mesh.updateVerticesDataDirectly instead, which never updates the bounding box and which executes a little less code than updateVerticesData. The bounding box is still created/set at creation time: doN…
