3D Rendering

3D Rendering

To go to the 3D mode, check "3D". The rendered image will be similar to linearly interporated 2D data.

The default settings are displayed on the right.

Gray Scale

You can display the data in three gray scales. There are 16 levels in Gray (16), 32 levels in Gray (32), and 256 levels in Gray (256). To select one of them, click "Scale Bar" and pick your choice.

Color Scale

You can display the data in three color scales. There are 16 levels in Color (16), 32 levels in Color (32), and 256 levels in Color (256). To select one of them, click "Scale Bar" and pick your choice.

Translation along The Y Axis

To translate the data along the y axis, adjust "y" slider in the "Translation" panel.

Mesh Rendering

The default rendering mode in 3D is surface rendering. To change it to the mesh rendering mode, check "Lines". The mesh displayed on the right is rendered by quads. To change the elements to triangles, check "Triangle" in the 2D panel.
