Curve to polygon?

[Juzwa]

Hi, 

So I decided that I want to model this in Houdini. It might be painful at the beginning but I want to start using Houdini more on a daily basis. 

I need a folded rolled piece of cloth, something like this:

Folded Rolled Cloth

So at first I thought that bend sop will help. But unfortunately it does some weird bending and I dont have enough control to roll the cloth together. It just creates a curly shape.

So my other idea is to start with curves! Ok owesome, but can I somehow convert curve shapes into polygons?

The Curve SOP in Houdini actually creates polygons by default, so you could actually just draw a rough poly curve and smooth it to get the right shape, but it's really no problem to start with NURBS. In that case, I would immediately follow the curve with a Convert SOP, then a PolyExtrude to get the base surface, followed by another PolyExtrude for thickness, just extrude along local Z axis in both. Remember to tick off the Output Front parameter in the first PolyExtrude though, otherwise the second won't work properly.

You can build surfaces from curves using rail, sweep, and skin. I attached a .hip that shows one way of doing this. Just a warning I am new to vex wrangles so it's probably not the best vex code and none of the parameters are bound.

I like Aaron's skinning of the carpet. I found a spiral unrolling line on the forum and mixed those two HIP files together to produce a 1st draft of a red carpet unrolling. You control the radius by simply sizing the cylinder inside the rolling_line_source.

Wow, owesome guys!

I will look at these tomorrow as I am going to sleep now
