float chrampderiv(string channel, float ramppos)
float chrampderiv(string channel, float ramppos, float time)
vector chrampderiv(string channel, float ramppos)
vector chrampderiv(string channel, float ramppos, float time)
Evaluates the derivative of a parm parameter with respect to position.
The ramppos is where on the ramp to evaluate. The ramppos is clamped to the range [0,1]
The time parameter can be used if the ramp is animated to evaluate at other than the current time. Note that this does not take a derivative with respect to time.
