Hi everybody,
I wrote this code that create a scene and add a vtkUnstructuredGrid to
it:
Note: the object i pass to AddGridToScene (cloud) is derived from
vtkUnstructuredGrid, so i need to call AsVTK() for passing it to the
to_tvtk function:
class RenderWindow:
def __init__(self):
self.engine = Engine()
self.engine.start()
if len(self.engine.scenes) == 0:
self.engine.new_scene()
self.scene = self.engine.scenes[0]
self.scene.scene.disable_render = True
#set up initial props
self.scene.scene.background = (0,0,0)
self.scene.scene.parallel_projection = True
self.scene.scene.x_minus_view()
self.xrotation = 0
self.yrotation = 0
self.PointPicker = PointPicker(self)
self.scene.scene.disable_render = False
def AddGridToScene(self, cloud):
self.source_cloud = cloud
self.scene.scene.disable_render = True
self.tvtksource = tvtk.to_tvtk(cloud.AsVTK())
self.source = VTKDataSource(data = self.tvtksource)
self.engine.add_source(self.source, self.scene)
surfacef = Surface()
self.engine.add_filter(surfacef,
self.engine.scenes[0].children[0])
self.scene.scene.disable_render = False
How can i update the object seen into my scene if i have modified the
"cloud" object?
For example: i call AddGridToScene, and after that i delete some points
from "cloud", how can i update the scene ?
I tried with self.tvtksource.update(), self.tvtksource.modified(),
self.source.update() but those does not work!!
Any idea??
Thanks

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
