[vtkusers] vtk-theory: some questions about "behind the curtains"

[Fabian]

Hi,

First of all thank You for your help and ideas. I am Newby and have just a
little idea of vtk's possibilities.

1. What I want to do is to write a little program, that gives me control
about most important model parameters. For example I want to set the exact
number of polygons, the exact texture volume, the number of lights, etc...
Then I measure rendertime. With this measurement I would like to analyze the
whole rendering process and to identify which parameter has which influence
on rendertime. Of course: the more polygons the longer is rendertime but I
want to know it exactly. Maybe its some kind of benchmark.

I chose many planes, because I have a lot control about the number of
polygons. Does this number change when using the AppendDataFilter? I could
imaging that easy shapes like polygons are merged?

I tried to use different techniques like TriangleStrips or vtkPolygon, but
firstly I didnt mange to run it properly and secondly I didnt like it ;-)
due to little control.

2. I am not sure about the CPU vs. GPU thing. The CPU usage rate for this
sinle core is 100% and that looked to me, as if further computing power
would be used if available?!


Thank YOU,
Fabian
