Hi everyone,
Quick question. I've put together a little function to find the
matrix_world Z location of a point on a displaced mesh (plane with ocean
mod) given the X and Y coordinates. I'm using an empty with a shrinkwrap
modifier to achieve this.
I was wondering if there is a faster or more direct way in python to do
this.
Here's what I have so far.
*****************************************
import bpy
def getZLocation(xLoc, yLoc, targetMeshName):
o = bpy.ops.object
d = bpy.data.objects
targetMesh = d[targetMeshName]
o.add(type='EMPTY', location=(xLoc, yLoc, 0))
empOb = bpy.context.active_object
empOb.name = 'empLocate'
o.constraint_add(type='SHRINKWRAP')
empOb.constraints['Shrinkwrap'].shrinkwrap_type='NEAREST_SURFACE'
empOb.constraints['Shrinkwrap'].target = targetMesh
o.select_all(action='DESELECT')
return empOb.matrix_world.to_translation()[2]
print(getZLocation(xLoc=2.2, yLoc=4.1, targetMeshName='Ocean'))
*****************************************
Also, it seems to take a few seconds to actually compute this value, so
something faster would also be great.
