PYTHON
        import math
node = hou.pwd()
geo = node.geometry()

cuts = node.evalParm('cuts')

clip = hou.sopNodeTypeCategory().nodeVerb('clip')

for i in range(cuts - 1):
    angle = i / (cuts - 1.0)
    dir = hou.Vector3(math.sin(angle * math.pi), 0.0, math.cos(angle * math.pi))
    clip.setParms({
        'dir': dir,
        'clipop': 2
    })
    geo.execute(clip, [])
    if hou.updateProgressAndCheckForInterrupt():
            break

node.geometry().merge(geo)
