function
MinSG::TriangleTrees::Builder::mergeGeometry

public

static

Rendering::Mesh * mergeGeometry(	const std::vector< GeometryNode * > &	geoNodes )

Collect all meshes from the GeometryNodes and store them together in a single mesh. The global transformation of the GeometryNodes is respected.

Parameters

geoNodes

Container with GeometryNodes.

Returns

A new mesh containing all the mesh data.

Exceptions

Exception

describing what went wrong.

function
MinSG::TriangleTrees::Builder::buildMinSGTree

public

static

Node * buildMinSGTree(	Rendering::Mesh *	mesh,
	Builder &	builder
)

Take the triangles from the given mesh and organize them in a hierarchical spatial data structure.

Parameters

mesh

Container holding the triangles.

builder

Builder specifying the way in which the tree will be built.

Returns

Root node of the tree.

function
MinSG::TriangleTrees::Builder::buildTriangleTree

public

virtual

TriangleTree * buildTriangleTree(	Rendering::Mesh *	mesh )

Take the triangles from the given mesh and organize them in the way that is defined by this builder.

Parameters

mesh

Container holding the triangles.

Returns

Root node of the tree.

function
MinSG::TriangleTrees::Builder::convert

protected

static

Node * convert(	const TriangleTree *	treeNode,
	const Rendering::VertexDescription &	vertexDesc
)

Convert TriangleTree nodes into MinSG nodes. Inner nodes will be converted to ListNodes. Leaves will be converted to GeometryNodes.

Parameters

treeNode

Root node of the tree to convert.

vertexDesc

Vertex description for the mesh data stored in the tree.

Returns

Converted MinSG node.
