Detailed Description

Shovel object used to interact with a terrain via an active zone that converts solid terrain to dynamic terrain which can be moved by the shovel rigid body.

A shovel object consists of a rigid body, two edges and a cutting direction. A convex inner shape is created between the two edges, the top edge and the cutting edge, and the attached rigid body. When the cutting edge intersects a terrain surface an active zone is created in the cutting direction inside the terrain, which then converts solid mass into dynamic mass. The shovel receives feedback forces through a rigid body aggregate constructed from the intertia of the soil particles in the active zone.

The shovel has 4 modes for deforming terrain: PRIMARY, DEFORM_BACK, DEFORM_LEFT and DEFORM_RIGHT. See the Shovel::ExcavationMode enum for details.

Constructor & Destructor Documentation

◆ Shovel() [1/2]

agxTerrain::Shovel::Shovel	(	agx::RigidBody *	shovelBody,
		const agx::Line &	topEdge,
		const agx::Line &	cuttingEdge,
		const agx::Vec3 &	cuttingDirection,
		Shovel *	connectedShovel = `nullptr`
	)

Basic constructor.

Parameters

shovelBody	- The base body of the shovel.
topEdge	- The top edge of the active zone, specified in the LOCAL shovelBody frame that will be created in front of the shovel.
cuttingEdge	- The lowest edge on the shovel, specified in the LOCAL shovelBody frame that serves as the cutting edge of the active zone.
cuttingDirection	- The cutting direction of the shovel where the penetration resistance will be active, which is usually parallel to the lowest shovel plate that is used to initially penetrate the soil.
connectedShovel	- Set if the shovel should be connected to another shovels InnerBody for purposes of simulating composite shovels with varying shovel vectors in along the shovel geometry. This means you can have multiple cutting edges with varying orientation per shovel where you have a central shovel with a single inner shape. (Default: nullptr)
