Voxel grid

This type of visual element controls the visual appearance of voxel grid data objects, which are structured grids made of 2- or 3-dimensional cells (voxels), each being associated with numeric property values.

The color mapping function of the visual element visualizes the selected scalar cell property using a pseudo-color map. Alternatively, it’s possible to control each voxel cell’s RGB color explicitly by setting the Color property of the voxel grid data object using modifiers in the pipelines.

A three-dimensional voxel grid is rendered as a solid box, showing just the values of the grid cells located on the outer boundaries of the domain. To visualize the interior values of the three-dimensional voxel grid, you can use the Slice modifier to extract a two-dimensional cross-section or use the Create isosurface modifier to compute an isosurface of the scalar field.

Parameters

Surface transparency: The degree of semi-transparency of the grid surfaces.
Show grid lines: Activates the rendering of wireframe lines along the edges of the grid cells.
Color interpolation: Smoothly interpolate between the discrete colors of adjacent cells.
