Detailed Description

A PSD (Position Sensitive Device) Sensor. A PSD sensor returns the distance between its location and direction and the nearest object. The process of doing so usually involves casting a ray and determining the intersection point to calculate the distance. The PSD sensor is therefore sometimes refered to as raycasting or raytraceing.

The diagram indicates the body to which the sensor is attached (the cube), the position at which the PSD sensor is located (the bottom of the arrow), and the direction which the PSD is facing (the tip of the arrow). The diagram illustrates the operation of the PSD, showing the PSD ray intersecting a neighbouring object. The length of the arrow is the distance returned when the PSD is queried.

virtual Float palPSDSensor::GetDistance

(

)

[pure virtual]

Returns the distance Casts a ray from the sensors current location and orientation to determine the nearest intersection point.

Returns:

The distance to the closest object

void palPSDSensor::Init	(	palBody *	body,
		Float	x,
		Float	y,
		Float	z,
		Float	axis_x,
		Float	axis_y,
		Float	axis_z,
		Float	range
	)			[virtual]

Initializes the PSD sensor. Attaches a PSD sensor to a given body, at specified position, and pointed in a given direction, with a maximum range.

Parameters:

	body	The body which the sensor is attached to.
	x	The position (x)
	y	The position (y)
	z	The position (z)
	axis_x	The direction vector the PSD is facing (x)
	axis_y	The direction vector the PSD is facing (y)
	axis_z	The direction vector the PSD is facing (z)
	range	The maximum range the PSD has
