C4D's Range mapper in ICE

[TheDutchOracle]

hi i was trying to figure out something (no solution yet)
maybe someone here knows the answer?

I was trying to recreate the 'Range Mapper' node from Cinema 4D in Ice.
(i figured it would be really simple but it hasn't been yet)

A while ago i did a little kitche animation where all objects were animated without keyframes. (setting starttime and end time by hand typed)
(see pictures) That's the range mapper.

(the basic kitchen scene where all objects were animated)


(The Xpresso nodes I used for animating them)


(the node-settings (in yellow highlight) for animating each object)


in short let's say i want to move 1 cube somewhere at frame 51
i want to type eventualy:
* Start frame
* End Frame
* Start Position
* End position
just like in the range mapper node from Cinema 4D
Someone knows if this is possible at all with ICE?

My first guess was to do something simple like this (then afterwards insert everything 1 one compound when i'm done)
this one is not corrected right yet, it does move from position A to position B based on time, but not with nice fcurve yet etc)

So this is just the basic idea 1.1 (not good execution yet)
This node when done will make simple SRT animations possible without keyframes.

my first attempt (1.2)
It does move to the new position at the right time (after 3 seconds) without keyframes , but not in fluid motion yet.





If anybody here is familiar with C4D's range mapper, ideas how to make this work in ICE is always welcome : )
Aftwrwards when it's done i can post the compound here + make a short project based tutorial on how to put it to use in a real project.

Could be "rescale" node, input is current frame, "source start" is start frame of animation, "source end" is end frame of animation. Output of rescale goes into lerp (linear interpolate), in lerp, you can set positions, to blend in between. If you want smooth interpolation, there is fCurve node to put in between rescale and lerp. That's just one way, there are other ways to.

In any way, you don't want to interpolate between matrices directly. If there's some rotation involved, matrix blend can do some kind of skew.

Also, if you're in un-simulated ICE tree, "current frame" probably won't catch, so you can use some animated parameter, instead of current frame, let's say rotation of some animated null.

Ah, using a null for that is a great idea, will try that (with rescale node now)

c4d rangemapper = ICE rescale

hi guys,
thanks for the replies, i just figured that out a second ago, i feel so dumb now : )
atm trying to combine an ice tree to create something like: http://c4dtools.net/psr-animator/
just to practice some ICE.

The basic setup is now (correct):
just posting this picture in case someone find it usefull...
