void gazebo::common::MeshManager::AddMesh ( Mesh * _mesh )

Add a mesh to the manager.

This MeshManager takes ownership of the mesh and will destroy it. See ~MeshManager.

Parameters

[in] the mesh to add.

		const ignition::math::Vector3d &	_sides,
		const ignition::math::Vector2d &	_uvCoords
	)

Create a Box mesh.

[in]	_name	the name of the new mesh
[in]	_sides	the x y x dimentions of eah side in meter
[in]	_uvCoords	the texture coordinates

void gazebo::common::MeshManager::CreateCamera	(	const std::string &	_name,
		float	_scale
	)

Create a Camera mesh.

Parameters

[in]	_name	name of the new mesh
[in]	_scale	scaling factor for the camera

void gazebo::common::MeshManager::CreateCone	(	const std::string &	_name,
		float	_radius,
		float	_height,
		int	_rings,
		int	_segments
	)

Create a cone mesh.

Parameters

[in]	_name	the name of the new mesh
[in]	_radius	the radius of the cylinder in the x y plane
[in]	_height	the height along z
[in]	_rings	the number of circles along the height
[in]	_segments	the number of segment per circle

void gazebo::common::MeshManager::CreateCylinder	(	const std::string &	_name,
		float	_radius,
		float	_height,
		int	_rings,
		int	_segments
	)

Create a cylinder mesh.

void gazebo::common::MeshManager::CreateExtrudedPolyline	(	const std::string &	_name,
		const std::vector< std::vector< ignition::math::Vector2d > > &	_vertices,
		double	_height
	)

Create an extruded mesh from polylines.

The polylines are assumed to be closed and non-intersecting. Delaunay triangulation is applied to create the resulting mesh. If there is more than one polyline, a ray casting algorithm will be used to identify the exterior/interior edges and remove holes from the 2D shape before extrusion.

Parameters

[in]	_name	the name of the new mesh
[in]	_vertices	A multidimensional vector of polylines and their vertices. Each element in the outer vector consists of a vector of vertices that describe one polyline. edges and remove the holes in the shape.
[in]	_height	the height of extrusion

void gazebo::common::MeshManager::CreatePlane	(	const std::string &	_name,
		const ignition::math::Planed &	_plane,
		const ignition::math::Vector2d &	_segments,
		const ignition::math::Vector2d &	_uvTile
	)

Create mesh for a plane.

Parameters

[in]	_name
[in]	_plane	plane parameters
[in]	_segments	number of segments in x and y
[in]	_uvTile	the texture tile size in x and y

void gazebo::common::MeshManager::CreatePlane	(	const std::string &	_name,
		const ignition::math::Vector3d &	_normal,
		const double	_d,
		const ignition::math::Vector2d &	_size,
		const ignition::math::Vector2d &	_segments,
		const ignition::math::Vector2d &	_uvTile
	)

Create mesh for a plane.

Parameters
