Documentation
This tool generates ig from primitive files
- Load the landscape zone. Load all the *.zonew found in the InLandscapeDir and add them in a landscape
- For each primitive files found in PrimDirs
- Look for points with the "prim" primitive class
- Get the good height on the landscape
- Get the .plant georges file associed with the point
- Add an entry in the good ig file
- Set the shape filename
- Set the plant name
- Set the final position (x and y come from the primitive and z from height test with the landscape, the rotation comes from the primitive)
- Set the ig date
- The date is the most recent date between the .zonew .plant .primitive files associed with the ig.
- Snap to ground only modified or created ig
- Save the modified or created ig files
