I am working on 3D Vector Field Visualization. I have a 30 by 30 by 30 uniform volume data and have the granularity of unit cube in the volume. I am not able to get functions for computing the vector field by taking the gradient of the function of 3 variables. I would very much appreciate if any of you can send information about numerical routines to compute the Gradient. Also, I need to have a function of 3 variables to test the vector field. I have tested using a function ex. exp(cos(sin(x))). Thanks in advance Krishna
