Add Isosurface Variable¶
Introduction¶
The Add Isosurface Variable function adds a field variable that is computed at the isosurface vertices. Whereas the Isosurface Field UDF and associated value define where to draw the isosurface, the Isosurface Variable defines what field values to map along the counter surface. This function is calculated on a voxel-by-voxel basis using the local fluid properties.
Access¶
When you select Add Isosurface Variable on the isosurface context-specific toolbar, a new child geometry is formed and the property grid below will launch.
Property Grid¶
General¶
- Data Type
Data type for field computed on isosurface.
- Scalar
Each cell value contains a single floating point value.
- Vector
Each cell value contains a three-component vector.
- Isosurface Contour UDF
user-defined units | This UDF defines the contour values to be computed along an isosurface. One output must be defined within the UDF: a floating point variable named
value. Whereas the Isosurface Field UDF and associated value define where to draw the isosurface, the Isosurface Contour UDF defines what field values to map along the counter surface. This is a voxel-based local UDF, calculated on a voxel-by-voxel basis using the local fluid properties.
