Référencer le node courant

node = hou.pwd()
node_name = node.name()  # Get the name of the current node
parent = node.parent()  # Get the parent node
path = node.path()  # Get the full path of the node

geo = node.geometry()
prims = geo.globPrims("0")
print(prims)
name = prims[0].attribValue("name")
node.setName("koko")

Définir la valeur d’un attribut

node = hou.pwd()
geo = node.geometry()
for prim in geo.prims():
    number = prim.number()
    prim.setAttribValue("name", "fragment_" + str(number))

Ajouter des attributs

node = hou.pwd()
geo = node.geometry()
geo.addAttrib(hou.attribType.Prim, "newAttrib", "neAttrib")

for prim in geo.prims():
    number = prim.number()
    prim.setAttribValue("ef", "fragment_" + str(number))

Manipulation des groupes

node = hou.pwd()
geo = node.geometry()


cd = (0,1,0)
geo.addAttrib(hou.attribType.Point, "Cd", cd)
grp = geo.createPointGroup("myptgroup")

mypts = geo.globPoints("0-50")

for pt in mypts:
    grp.add(pt)
    pt.setAttribValue("Cd", (1,0,0))

Créer un groupe avec une bounding box

node = hou.pwd()
geo = node.geometry()

box = node.inputs()[1].geometry().boundingBox()

cd = (0,1,0)
geo.addAttrib(hou.attribType.Point, "Cd", cd)
grp = geo.createPointGroup("myptgroup")


for pt in geo.points():
    pos = pt.position()
    included = box.contains(pos)
    if included == 1:
        grp.add(pt)
        pt.setAttribValue("Cd", (1,0,0))

geo.deletePoints(grp.points())

Points les plus proches : voisins de points

import hou
node = hou.pwd()
geo = node.inputs()[1].geometry()

cd = (0,1,0)
geo.addAttrib(hou.attribType.Point, "Cd", cd)
grp = geo.createPointGroup("myptgroup")

for pt in box.points():
    pos = pt.position()
    nearpts = geo.nearestPoints(pos, 100, None, 1)
    for nearpt in nearpts:
        nearpt.setAttribValue("Cd", (1,0,0))
