Detailed Description

A DrawableMesh which can produce shapes for the Bullet physics library.

When created you should use bit masks for the type of shape you want to produce: a convex hull (fastest for moving objects), a triangle mesh for the bullet physics library (good for static geometry), or both.

[private]

Track::BulletMesh::BulletMesh	(	std::string	filename,
		unsigned int	generators = genererator_triangle_mesh_bit,
		DrawableMesh::RenderMode	render_mode = DrawableMesh::RM_SOLID
	)

Construct some objects from the mesh specifed by the file given.

Parameters:

	filename	The name and path of a file containing the mesh to load.
	generators	A bit mask made from the above three constants to determine which objects to create.
	render_mode	The method to use to draw the mesh.

Definition at line 25 of file BulletMesh.cpp.

Track::BulletMesh::BulletMesh	(	std::istream &	source,
		unsigned int	generators = genererator_triangle_mesh_bit,
		DrawableMesh::RenderMode	render_mode = DrawableMesh::RM_SOLID
	)

Construct some objects from the mesh specified by a stream.

Parameters:

	generators	A bit mask made from the generator constants to determine which objects to create.
	source	The stream to load the mesh from.
	render_mode	The method to use to draw the mesh.

Member Function Documentation

void Track::BulletMesh::create

(

unsigned int

generators = genererator_triangle_mesh_bit

)

[private]

Create the triangle / convex hull shape.

Definition at line 52 of file BulletMesh.cpp.

btConvexHullShape * Track::BulletMesh::get_convex_hull_shape

(

)

Get the convex hull of the vertices in the mesh.

It should be efficent for calculating physics when used for a moving object.

Returns:

Pointer to convex hull shape, which deleted with the BulletMesh.

Definition at line 110 of file BulletMesh.cpp.

btBvhTriangleMeshShape * Track::BulletMesh::get_triangle_shape

(

)

Get a Bullet btBvhTriangleMeshShape representing the faces in the mesh.

It is uesful for static geometry.

Returns:

Pointer to triangle mesh shape, which deleted with the BulletMesh.
