Hi,
I was thinking that a nice way to create a display proxy for our hires vegetation blocks would be a reduced point cloud of it.
Can someone help me with that? It should basically work like this:
- select the geometry (mesh) for pointcloud extraction
- extract pointcloud from the selected mesh
- reduce the number of points in the pointcloud by N% (slider) or to a fixed, user defined amount
- create a new pointcloud from the remaining points
- bake pointcloud
I would use the pointcloud as a display placeholder, to show the approximate volume of the object.
Right now I “redraw” the object with curves, which is kind of time consuming and not very accurate.
The real geometry to be rendered is hidden by using a custom made display mode (“invisible”) which is not showing meshes. The display mode is assigned to the object by using the “setObjectDisplayMode” command.
We are using this technique for a few years now to be able to create larger scenes with plenty of hires vegetation blocks, although it works quite well, but I would prefer If McNeel would come up with a build in Rhino solution to be able to define a display proxy.
thank you for any help
Andreas
