gradually speed up

Orbaz has a great plugin for Pflow called Stop Gradually. I'm wondering is there also something like start gradually?

Hey hvanzon, you can do it using Data Operators.

Maybe there's a better way to achieve it but it work's fine.

To make it easy to understand, that's my particle view:



and that's what's going on inside the Data Operator:



The Speed Vector on the top (with the arrow pointing down) is an Input Standard (it's set to Speed Vector). This operator will get all the Speed data that this event have. In this case (on the particle view flow) there's a speed operator set to 1.

The # on the top right is a Scalar operator. It will create a real value..

Then we have a function. It says that the first value will be multiplied by the second one. I set it to get a Real Value on the Second Operand R2.

Then this function is connected to an Output Standard set to Speed Vector (just like the Input Standard). It get's this value and send back to the particle view.

The file is attached so you can undertand it better.

I hope it can help you.

Yep. At a first sight it can look's very complex but when you realise what's going on it gets easier.

Add a Condition to one of the switch booleans so when it reaches the desired speed magnitude it will stop increasing

Thank's

On top of my head i would think use ADM (Box#3) and divide age by life span to get a normalized multipiler and add that to the speed. then use a pipe and limit the top speed.

max 2014 file start-gradually

Hey Anselm von Seherr, what is this ADM you're talking about? I'm afraid I don't have it in max 2014 because when I open your file it gives me a warning:

"The MassFX authored in this file was created with a newer version of plugins. Forward compatibility is not supported, so things might not behave properly"

ADM = "Advanced Data Manipulation" ie Max integrated PF Tools Box #3

Nice Ansi by age

This is a bit too simple, I would prefer to make it a little more clear by convert the values to ones you are used to seeing in the Speed Operator and exposing the params but I can't figure out the math for one of the directions. Anyway this one is accel to a given speed:

Nice! works like a charm. And it explains so many about the data operator. It's so powerfull
