37. Granular Coloring

Note

Feature requires a Momentum Granular license

Color bodies emitted by an emitter by property.

37.1. Usage

1. Select Color Granular Shapes from the ribbon menu.

2. Select a coloring mode you want to color the bodies by.

3. Select a minimum value and maximum value. The body will be colored based on what value compared to the minimum and maximum value

37.2. Coloring Modes

It is currently possible to color emitted bodies by velocity and max impact energy.

37.2.1. Velocity

If we choose to color by velocity the color of the bodies will depend on their current velocity.

37.2.2. Max Impact Energy

If we choose the color by max impact energy the color of the bodies will depend on the maximum impact the bodies has registered. The maximum impact a body has registered is equal to the maximum energy dissipated in any contact the body has been a part of. The dissipated energy for a contact is computed as:

(37.1)\[\begin{equation} W = \lambda \frac{( v_t + v_{t + 1})}{2} \end{equation}\]

Where \(\lambda\) is the impact lambda, \(v_t\) is the pre impact speed and \(v_{t+1}\) is the post impact speed.
