Constructor Detail

MeshReader

public MeshReader(OEMM o)

Constructor.

Parameters:

o - OEMM instance

Method Detail

setLoadNonReadableTriangles

public void setLoadNonReadableTriangles(boolean loadNonReadableTriangles)

Allows reading non-readable triangles. On disk, a triangle is contained in one single leaf. If it contains vertices from octants which are not loaded, this triangle can not be drawn and is said to be non-readable. If argument is true, such vertices are loaded from disk to make these triangles as being readable.

Parameters:

loadNonReadableTriangles - behavior expected.

buildMeshes

public void buildMeshes(MeshTraitsBuilder mtb)

Builds meshes for all octants. This method maintains a map in memory of meshes from all octants; each mesh can be retrieved by getMesh(int).

Parameters:

mtb - mesh traits builder used to create Mesh instances

getMesh

public Mesh getMesh(int leafIndex)

Gets the mesh contained in an octant.

Parameters:

leafIndex - octant index

Returns:

mesh contained in these octants

buildWholeMesh

public Mesh buildWholeMesh()

Builds a mesh composed of all octants.

Returns:

mesh contained in all octants

buildMesh

public Mesh buildMesh(TIntHashSet leaves)

Builds a mesh composed of specified octants.

Parameters:

leaves - set of selected octants

Returns:

mesh contained in these octants

buildMesh

public Mesh buildMesh(MeshTraitsBuilder mtb,
                      TIntHashSet leaves)

Builds a mesh composed of specified octants.

Parameters:

mtb - mesh traits builder used to create Mesh instances

leaves - set of selected octants

Returns:

mesh contained in these octants
