VTK (Visualization ToolKit) is a file format for 3-D computer-aided design and modeling.

This format has both text-based and binary variants.

It does not support coloring.

The plottools[importplot] and plottools[exportplot] commands can be used for data exchange between this format and Maple 3-D plots. Currently, only the text-based variant is supported.

The general-purpose commands Import and Export also support this format.
