@Armin, in case of 3D charts the creation of the shapes itself takes very long
whereas the completeRedraw-call is very fast in comparison. Adding a new
Shape3DPolygonObject and setting properties at these shapes is what seem to be
most expensive here. It somehow feels if every change in the draw model already
leads to a complete recalculation and view preparation. Please have a look
whether the recalculations can be moved to a later time in process when they are
really needed. This might be related to some of the work you are currently on
:-).
An additional idea. In former times you advised me to create all this single
simple polygon shapes for each data point. If I remember correctly the reason
was that the area fillings, the shadings and/or the surrounding lines didn't
look good with one deep polygon shape. Maybe it is a good time now to reconsider
this decision and the reasons as the drawing engine has been reworked? Please
let me know your suggestions!
