How can I get this to generate points in a curve parameter? I forgot how to use a python expression, any help is appreciated!

for (x,y,z) in zip(range(10),range(10),range(10)):
print “%f,%f,%f ” % (x,y,z)

(Im using a mac btw if that makes it a different story)

Right click Coordinates Parameter first, select expression->toggle expression, then enter the code as follow.


a=' ‘
for (x,y,z) in zip(range(10),range(10),range(10)):
a+=’%f,%f,%f ' %(x,y,z)
return a

seems as though the coords parm doesn't like that…. is there something to let Houdini know when you type in python?

It looks like the coordinates parameter isn't able to change the expression type. A solution is to add a spare parm and use that to contain your code and reference that from the coordinate parameter. See attached.

You might also be able to do it using a custom Python Sop operator.

I'll see about submitting a bug for not being able to change the parameter to Python.

thanks a million!
