mrpt::nav::ClearanceDiagram Class Reference

Detailed Description

Clearance information for one particular PTG and one set of obstacles.

Usage:

• Declare an object of this type (it will be initialized to "empty"),
• Call CParameterizedTrajectoryGenerator::initClearanceDiagram()
• Repeatedly call CParameterizedTrajectoryGenerator::updateClearance() for each 2D obstacle point.
