Houdini模块：toolutils

• 查询某一类型所有节点，比如查询所有的File Cache节点

import toolutils

nodes = toolutils.findAllChildNodesOfType(hou.node("/obj"), "filecache", dorecurse=True)

for node in nodes:
    print(node.path())

• 与Scene View窗口交互，比如只能选择相机得到结果。

import toolutils

scene_viewer = toolutils.sceneViewer()
selected_objects = scene_viewer.selectObjects("Select a camera and press Enter", allowed_types = ["cam"])
print(selected_objects)

• 设置当前视图相机

>>> import toolutils
>>> scene_view = toolutils.sceneViewer()
>>> viewport = scene_view.curViewport()
>>> viewport.setCamera(hou.node("/obj/cam1/"))
>>>

import toolutils

kwargs["pane"] = None

toolutils.createOrShowPythonPanel(kwargs, "attribmanager", "Attribute Manager", 4)

>>> import toolutils
>>>
>>> scene_view = toolutils.sceneViewer()
>>>
>>> scene_view
<hou.SceneViewer panetab1>
>>> scene_view.pwd()
<hou.Node at /obj>
>>> scene_view.pwd()
<hou.ObjNode of type geo at /obj/geo1>
>>> scene_view.curViewport()
<hou.GeometryViewport persp1 of type Perspective>
>>>
>>> viewport = scene_view.curViewport()
>>> viewport
<hou.GeometryViewport persp1 of type Perspective>
>>> settings = viewport.settings()
>>> settings
<hou.GeometryViewportSettings>
>>>
>>> settings.camera()
>>> settings.camera()
<hou.ObjNode of type cam at /obj/cam1>
>>>
