Hide front faces
Hides the binary front faces so that the inside of the binary volume is more visible.
Mesh line thickness slider
Adjusts the thickness of the mesh line.
Density
Sets the density of the triangular mesh.
Remeshing
Remeshing adjusts the grid to the most regular equilateral triangles. Uniform remeshing makes all triangles the same size; it adaptively adjusts the size of the triangles and thus the density of the mesh according to the local complexity of the shape. Adaptive remeshing has a minimum triangle size the same as uniform, so it is allowed to reduce the grid density on large simple areas, but does not densify around details. This is because the mesh is mainly used to achieve binary transparency, so that a dense, opaque mesh does not form around fine details.
Centroid radius slider
Adjusts the size of the binary centroid(s).
Detailed description can be found here: Displaying a Grid.

Sets how much of the RAM memory can the full-res mode use. For optimal running, it is best to keep as much of the document ready in RAM as possible, but please keep in mind that the system and other processes within NIS-Elements also need some memory to run.
Sets the quality of displaying images. The level of detail in full-res varies according to the current view angle and especially the zoom factor. This factor determines how “pixelated” the data can be. In practice, this means that at a value of 1 the highest quality will be preferred. At a value of 5, you will need to zoom in for detail, but the smaller data volume will make the viewing much faster.
Sets how to handle preloading of oversized datasets.
The user is prompted every time there is a need to generate the acceleration file.
Only portions of the dataset which are needed for the current view load automatically. It displays the image faster than the Preload option at first, but it subsequent manipulation is slower.
