Image 3-D

The image3D draws images or functions as 3-D surfaces (Fig. 1)

.

Figure 1 ZnTe HAADF as a 3-D image.

The toolbar contains tool buttons to:

Drawing controls are located on the right pane and allows to change the lights or lights color, to shade the surface or make it transparent (Fig. 2, 3). By default, 3-D rendering is disabled.

Displaying experimental images in 3-D enhances the background of ring the pattern (Fig. 4).

Functions can be plotted in 3-D. They are defined using a Mathematica like syntax (Fig. 5).

Figure 6 3-D display of the gaussian.

Note
  1. The observator position is changed by moving the mouse with the left mouse button down. A translation of the observator is obtained when the mouse is moved with the right button down. Mouse movement with Alt key and left button zoom in or out the drawing.

  2. Culling is used to suppress the rendering of hidden polygons. This option uses opengl commands not available on some operating system.
