Detailed Description

Deprecated:: This class enables the visualization of 3D scenes by outputting various geometric objects (such as points, segments, and triangles) to a file, which can then be displayed using the Geomview viewer. This viewer is reliable, fast, and minimal. However, despite these advantages, Geomview is outdated and only available on Linux. Therefore, it is recommended to use the VtkWriter class instead, for creating visualizations in the widely supported VTK file format. VTK files are compatible with many viewers, and if you're new to this format, try using Paraview.

See also: VtkWriter A class for creating VTK visualization files.
