How to generate isosurface plots?

[jtristano]

I've seen in the gallery how people generate beautiful isosruface/level surface plots in glvis but I cant find the commands to generate them. What's the secret to generating level surfaces based on min/max ranges?

Thanks Joe

First, press the e key to hide the boundary elements; then press u/U to move the level set value; to add/remove more level sets use v/V. This is documented here: https://github.com/GLVis/glvis/blob/master/README.md#key-commands and in the more advanced keys for 3D scalar data, here: https://github.com/GLVis/glvis/blob/master/README.md#3d-scalar-data. You can also use the cutting plane to see inside the level sets (without that you'll probably see just the outermost level set) -- use the i key for that (see the above docs). By default, the cutting plane is colored using solution values, however you can hide it with the E key (see the docs). The cutting plane can be rotated and moved using x/X, y/Y, and z/Z (see the docs).

Beautiful! Thanks!
