Référencer le node courant
==========================

.. code-block:: python

    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
-------------------------------

.. code-block:: python

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

Ajouter des attributs
---------------------

.. code-block:: python

    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
------------------------

.. code-block:: python

    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
-------------------------------------

.. code-block:: python

    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
-------------------------------------------

.. code-block:: python

    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))
