Constructor & Destructor Documentation

◆ BulletDskShape() [1/2]

Isis::BulletDskShape::BulletDskShape ( )

Default empty constructor.

Definition at line 51 of file BulletDskShape.cpp.

◆ BulletDskShape() [2/2]

Isis::BulletDskShape::BulletDskShape ( const QString & dskfile )

Construct a BulletDskShape from a DSK file.

Parameters

dskfile The DSK file to load into a Bullet target shape.

Definition at line 59 of file BulletDskShape.cpp.

References loadFromDsk(), and Isis::BulletTargetShape::setMaximumDistance().

◆ ~BulletDskShape()

Isis::BulletDskShape::~BulletDskShape ( )

virtual

Desctructor.

Definition at line 68 of file BulletDskShape.cpp.

Member Function Documentation

◆ body()

btCollisionObject * Isis::BulletTargetShape::body ( ) const

inherited

Return a pointer to the Bullet target object/shape.

Returns: btCollisionObject A target to the Bullet collision object.

Definition at line 167 of file BulletTargetShape.cpp.

References Isis::BulletTargetShape::m_btbody.

Referenced by Isis::BulletWorldManager::addTarget(), and Isis::BulletTargetShape::setTargetBody().

◆ getNormal()

btVector3 Isis::BulletDskShape::getNormal	(	const int	indexId,
		const int	segment = `0`
	)		const

virtual

Return normal for a given triangle index.

This method is particularly useful to return the normal of a triangle plate in a mesh-based target body.

Author: 2017-03-28 Kris Becker

Parameters

indexId The index of the triangle in the mesh.

Returns: btVector3 The local normal for the triangle.

Definition at line 130 of file BulletDskShape.cpp.

References getTriangle().

◆ getNumTriangles()

int Isis::BulletDskShape::getNumTriangles ( ) const

Return the number of triangles in the shape.

Returns: int The number of triangles. If nothing has been loaded, then 0 is returned.

Definition at line 87 of file BulletDskShape.cpp.

◆ getNumVertices()

int Isis::BulletDskShape::getNumVertices ( ) const

Return the number of verticies in the shape.

Returns: int The number of verticies. If nothing has been loaded, then 0 is returned.

Definition at line 105 of file BulletDskShape.cpp.

◆ getTriangle()

btMatrix3x3 Isis::BulletDskShape::getTriangle	(	const int	index,
		const int	segment = `0`
	)		const

virtual

Get the vertices of a triangle in the mesh.

Parameters

index The index of the triangle in the mesh.

Returns: btMatrix3x3 Matrix with each row containing the coordinate of a vertex. The vertices are ordered counter-clockwise around the surface normal of the triangle.

Definition at line 147 of file BulletDskShape.cpp.

◆ load()

BulletTargetShape * Isis::BulletTargetShape::load	(	const QString &	dem,
		const Pvl *	conf = `0`
	)

staticinherited

Load a DEM file into the target shape.

Parameters

dem	The DEM file to load.
conf	PVL config for the DEM load. Currently unused.

Returns: BulletTargetShape A target shape containing the DEM

◆ loadCube()

BulletTargetShape * Isis::BulletTargetShape::loadCube	(	const QString &	dem,
		const Pvl *	conf = `0`
	)

staticinherited

Load an ISIS cube type DEM in Bullet.

Note: Currently not implemented

Parameters

dem	The DEM file to load.
conf	PVL config for the DEM load. Currently unused.

Returns: BulletTargetShape A target shape containing the DEM

◆ loadDSK()

BulletTargetShape * Isis::BulletTargetShape::loadDSK	(	const QString &	dem,
		const Pvl *	conf = `0`
	)

staticinherited

Load a DSK in Bullet.

Parameters

dem	The DEM file to load.
conf	PVL config for the DEM load. Currently unused.

Returns: BulletTargetShape A target shape containing the DEM

◆ loadFromDsk()

void Isis::BulletDskShape::loadFromDsk ( const QString & dskfile )

private

! Triangular mesh representation of the target shape.

Load the contents of a NAIF DSK and create a Bullet triangle mesh.

The vertex ordering is the same as in the DSK file, except the DSK uses 1-based indexing and this uses 0-based indexing.

Author: 2017-03-28 Kris Becker

Parameters

dskfile The DSK file to load.

NAIF DSK parameter setup
< The DAS file handle of the DSK file.
