How do I create a velocity gradient volume?
Follow the steps below to display the vertical gradient of a velocity volume at any point. Using the velocity gradient, large changes in the velocity can be easily seen.
1. Copy volume
To be able to display the velocity gradient, a duplicate of the velocity volume is required.
Follow the steps in Creating a Copy of a Volume to create a copy, export and configure the velocity volume.
2. Set bulk shift
After creating a copy of the velocity volume, shift the duplicate volume by the desired value, e.g. -100 ms (see Manual Mistie Corrections).
3. Volume math
Create another Volume Maths process, and select the original and the duplicate volume. At Formula, type
- v2 = copied and shifted velocity
- v1 = original velocity volume.
As a result of this process, a new volume is available in the Volume tab based on the Formula.
