# Import velocity and banking parameters

Hello everyone,

I am working on a roller coaster in 3DS Max 2012. I am use to 'still' renderings, so the animation side is new to me.

What do I need help with?
I am looking for a script that will import velocity values at intervals along the path(spline) for intially a camera (doing a Point Of View on the coaster), and then my single car train which I have built.
I don't want to manually set the velocity at each point on the path as it would take too long becuase I have my time intervals at 0.04 seconds.

I have relative (excel document) and absolute (.dat file) information which is detailed below.

I am hoping someone can help me out with a script, mainly for velocity.
Tomorrow I am going to look at the banking again, as I have 2 splines (left and right rail) which can be set as path constraints for the 1 object (camera or single car) thus solving my banking issue <-- I just realised this in the past hour ;-)

Below is part of my post in CGTalk which has led me here

--------------

I have both relative and absolute banking and velocity information.

Relative:

With a time based step size of 0.04 seconds I have the value for banking and speed. I created it in excel with columns for time(0.04s,0.08s,0.12s etc), banking angle (degrees), velocity (m/s),height (elevation from the ground, metres) travel distance on the tack (metres) and also ride percentage covered of the track distance(%). The ride last 69.44s and is 458.9m in travel length.

Absolute: This is in a .dat file....I have the x, y z position (metres) of this path for the camera including slope (degrees) ,banking (degrees) and velocty (m/s). It has a time based step size of 0.04 seconds as well.

I need help on applying the banking and velocity values accurately to my imported 3D polyline from AutoCAD. Or maybe from my excel or .dat file 3DS Max can draw out this path without the need for my import 3D polyline.

### that's ok

I am willing to pay for a script if need be..not got lots of money but hey, I appreciate if someone can help. I do wonder that noone has imported a velocity line for an animation before.
I can't see any other way around it.

### sounds to me like you will

sounds to me like you will have to pay someone to script this for you

Never get low & slow & out of ideas
