We're all familiar with using Houdini's ramps UI to manipulate existing attributes, but what if we whished to store the "value" of a ramp parameter AS an attribute? I know there's a mathematical definition that describes a ramp curve (or just about any curve), but is there a simple way to access this representation from a ramp parameter and store it as an attribute, and then reference this curve in a vex wrangle?

Or would the best way to do this be storing the ramp parameter's path as a string, and then using chramp()?

If you're doing something like morphing the location of points in a mesh from one location to another, being able to do something like randomly assigning some percentage of the points to use a quadratic interpolation vs a linear interpolation would be useful!

Having a direct reference to a ramp parameter would be useful, so you could make adjustments to the ramp on the fly using houdini's competent ramp UI.

use Attribute From Parameters SOP to store ramp parameters as string, check Flatten Ramps

then you can evaluate those at any position using ramp_lookup() [www.sidefx.com]
or use ramp_unpack() [www.sidefx.com], ramp_pack() [www.sidefx.com] to alter or create that string in VEX
