1.1. How to extract a Numpy Array from a Channel

In this example we access the Channel numpy array.

First create a example channel:

from ORSModel import Channel
channel = Channel()
#set it sizes, since we use the default voxel size, the channel is for now 100 meter cube
channel.setXYZTSize(100,100,100,1)
channel.setXSpacing(0.01)
channel.setYSpacing(0.01)
channel.setZSpacing(0.01)
#now the channel is 1 meter cube
#initilize it for float32 data
channel.initializeDataForFLOAT()
#publish it so that it is visible in the Object properties list
channel.publish()

And access it NDArray:

array = channel.getNDArray()
#modify it data
array[::2,::2,::2] = 1
#tell the channel that it data was modified (this can trigger event)
channel.setDataDirty()
