In 'for' loop inside function shape must be 'i < np' instead of 'i = np', which is always true now and loop is endless.

i = np is not always true, it's that it never satisfies an initial condition. So it's more that it just hangs and doesn't loop at all, rather than endlessly loops.

If you put a delete node before the Null1 to remove all points and then return to the wrangle with i = np you will see it loops at least once since np is 0 and i = 0 in the first iteration - 'allowing it to pass through'. However, since there are no points, there is no attribute values to get and you have an empty array as the result.

Polygon File Format or the Stanford Triangle Format

It depends on the 3d printing company and their requirements.

You can export the model to an stl file and have a 3d company like Shapeways, iMaterialize, etc. print it off.

However, I'm not sure of the process if you want a colored model.

iMaterialize does say they can do colored stl. Not sure if the color should be applied to points or the prims - but there is the step of first how to convert the shop material to a color attribute.(I thought I could find a map of the shop material used in the install directory and use an attribute from map - but no luck).

Shapeways seems to be able to do the same plus they have a voxel based option too. The only information on I found on their website in relation to how to set up the color information involves packing up in a zip file with VRML97/X3D with jpg/png maps. Not sure what steps would have to be taken from Houdini side to get to that though - []

Edit: If one applies color attribute to any point/vertex/prims and save as stl. Loading it back in shows that information is lost. So I think one might have to look at another program that could save out a colored stl.
