Detailed Description

Generic simulation program.

To set up the world and simulation from a command line, call LoadAndInitSim(). To set up the simulation from a world, just InitSim(). To change the default controller, override the InitController(int i) method.

Messages are defined as follows.


In the current format, elements in the world should not be added/deleted after initialization.

Member Function Documentation

void Klampt::SimGUIBackend::DrawSensor ( int  robot = -1,
int  sensor = -1 

Draws sensor readings on the world visualization. If robot < 0, draws all the robots/sensors. If sensor < 0, draws all the sensors on the given robot.

bool Klampt::SimGUIBackend::SendLinearPath ( const vector< Real > &  times,
const vector< Config > &  milestones,
Real  pathDelay = 0.1 

Sends a linear path to the controller. The path starts pathDelay seconds after the current time
