Hello, Quick question,what is the reason for processing the points first even then odd in the python field example code?

Also, is there somewhere I can find any other example code for use in a python Field?

Thank you,

Nick

```
import c4d
import math
from c4d.modules import mograph as mo
#Welcome to the world of Python Fields
def Sample(op, inputs, outputs, info):
"""Calculate the output values for the specified set
of input points. Allocations should be avoided in Sample
to maximize performance.
Return false on error to cancel sampling.
NOTE: Sample function is mandatory, PythonField cannot
function without it.
Keyword arguments:
BaseObject -- the python field.
FieldInput -- the points to sample.
FieldOutput -- the sampling output arrays (pre-allocated).
FieldInfo -- the sampling informations.

outputs.SetValue(i, offsetValue)
# Second pass on odd points to calculate values

# Just use the sin-cos wave to generate a color.
value = outputs.GetValue(i)
outputs.SetColor(i, c4d.Vector(value, 0.0, 0.0))
outputs.SetAlpha(i, value)
