Click on the Options button for the Render Isosurface operator in the Operators list.
The Isosurface Options box appears.
The display at the top of the savi3D Controls window changes from the time display to the label "Rendering" when the graphics window (saviWIN) is calculating and drawing a new image.
A blue isosurface appears, displaying an irregularly shaped surface passing through the locations in the grid where the selected variable (C) has the specified value (1.0). The selected variable's values determine the shape and default color of the isosurface. Color is used to shade the surface giving it depth and shape and not to indicate values.
The isosurface created here represents the shape of a plume of benzene, below ground, at 1 ppb concentration. In this case, the loser the Isosurface Value, the larger the plume because this data depicts a chemical slowly dispersing from higher to lower concentration.
