[Paraview-developers] Rendering in Paraview using python

[sumeet kumar]

Hi Andy,

LoadPlugin() helps in pvpython. But why does
*from  paraview.simple import * *does not work???

Why I need to externally load my plugin even I build with paraview source.
Also, I don't think, Its a good design to set PV_PLUGIN_PATH  or
PV_PLUGIN_CONFIG_FILE even when the plugin is build with source. The file
"plugin.cmake" should take care all of this.

Thanks
Sumeet
