You can use this type of Channel Modifier to measure the angle formed between any three 3D items in the scene.
Position From: Use to link the World Position transform channel of a 3D item or the Position transform output of another Channel Modifier item into this channel.
Position To A: Use to link the World Position transform channel of a second 3D item or the Position transform output of another Channel Modifier item into this channel.
Position To B: Use to link the World Position transform channel of a third 3D item or the Position transform output of another Channel Modifier item into this channel.
Angle Output: Modo passes the floating-point value of the angle between the three items to this channel.
You can use the Measure Distance Channel Modifier to measure the distance between any two items in the scene.
Position From: Use to link the World Position transform channel of a 3D item or the Position transform output of another Channel Modifier item into this channel.
Position To: Use to link the World Position transform channel of a second 3D item or the Position transform output of another Channel Modifier item into this channel.
NOTE: If you leave either of these input channels unlinked Modo outputs the distance from the World origin.
The Measure Speed Channel Modifier takes a transformation matrix (such as a World Position) and passes a single value, which represents the overall speed of the input item measured in meters per second. Modo draws a blue line in the viewport with the numerical readout to provide a visual representation of the speed.
World Position: Use to link the World Position matrix of the moving item into this channel.
Speed: Shows the speed per frame of the input item in meters per second.
The Measure Velocity Channel Modifier takes a transformation matrix (such as a World Position) and passes a vector that represents the velocity of the input item. Each output of the vector represents the speed of the item for an axis and is given in meters per second. Modo draws a blue line in the viewport to provide a visual representation of the velocity.
World Position: Use to link the World Position matrix of the moving item into the World Position input of the Measure modifier.
Velocity X/Velocity Y/Velocity Z: Modo calculates the velocity per frame in meters per second from the input item and passes a vector for each axis.
