Viewport Display

Thickness

Factor that scales the thickness of the grid that is currently being displayed.

Slicing

How to slice the volume for viewport rendering.

View

Slice the volume parallel to the view plane.

Axis

Slice the volume parallel to the major axis.

Method

Full

Slice the whole domain object.

Single

Perform a single slice of the domain object.

Axis

Auto

Adjust slice direction according to the view direction.

X/Y/Z

Slice along the X/Y/Z axis.

Position

Position of the slice relative to the length of the respective domain side.

Slice Per Voxel

Determines how many slices per voxel should be generated.

Interpolation

Interpolation method to use for the visualization of the fluid grid.

Linear

Linear interpolation between voxels. Gives good smoothness and speed.

Cubic

Cubic interpolation between voxels. Gives smoothed high quality interpolation, but is slower.

Color Mapping

Use a specific color map for the visualization of the simulation field. This comes in handy during debugging or when making more advanced adjustments to the simulation. For instance, if the actual color of a fire simulation is barely visible in the viewport then changing the color profile can help to see the real size of the flame.

Field

The simulation field used in the display options (e.g. density, fuel, heat).

Comparison of a fire simulation with and without color mapping.

Debug Velocity

Visualization options for the velocity field.

Display As

Streamlines

Choose to display the velocity vectors as “Streamlines”.

Needle

Choose to display the velocity vectors as “Needles”.

Scale

Scale the velocity vectors by this size in the viewport.
