How to create geometry in standalone hython script?
Aug. 18, 2020 3:04 p.m.
import hou
import sys
def main ( output_hip ):
geo_node = hou . node ( '/obj' ) . createNode ( 'geo' )
nurb_surface = hou . Geometry () . createNURBSSurface ( 10 , 10 )
hou . hipFile . save ( file_name = output_hip )
if __name__ == "__main__" :
if len ( sys . argv ) == 2 :
main ( output_hip = sys . argv [ 1 ])
How do I associate the newly create nurb_surface with the ‘geo’ node ? My created hip file only has ‘geo1’ but not the NURBS surface geometry.
Cheers

A hip file typically doesn't contain any geometry, but the instructions for creating it. Put the code creating hou.geometry in a python sop's code snippet.

Something like this maybe.
import hou
import sys
def main ( output_hip ):
geo_node = hou . node ( '/obj' ) . createNode ( 'geo' )
pysop = geo_node . createNode ( 'python' )
code = \
'''
node = hou.pwd()
geo = node.geometry()
geo.createNURBSSurface(10,10)
'''
pysop . parm ( 'python' ) . set ( code )
hou . hipFile . save ( file_name = output_hip )
if __name__ == "__main__" :
if len ( sys . argv ) == 2 :
main ( output_hip = sys . argv [ 1 ])
