buildFaceArray()

void G3D::ArticulatedModel::Geometry::buildFaceArray	(	Array< Face > &	faceArray,
		Face::AdjacentFaceTable &	adjacentFaceTable,
		const Array< Mesh *> &	meshes
	)

cleanGeometry()

void G3D::ArticulatedModel::Geometry::cleanGeometry	(	const CleanGeometrySettings &	settings,
		const Array< Mesh *> &	meshes
	)

Cleans the geometric data in response to changes, or after load.

• Wipes out the GPU vertex attribute data.
• Computes a vertex normal for every element whose normal.x is fnan() (or if the normal array is empty).
• If there are texture coordinates, computes a tangent for every element whose tangent.x is fnan() (or if the tangent array is empty).
• Merges all vertices with identical indices.
• Updates all Mesh indices accordingly.
• Recomputes the bounding sphere and box.

Does not upload to the GPU.

Note that this invokes clearVertexRanges() and computeBounds().

subdivideUntilThresholdEdgeLength()

void G3D::ArticulatedModel::Geometry::subdivideUntilThresholdEdgeLength	(	const Array< Mesh *> &	affectedMeshes,
		const float	edgeLengthThreshold = 0.1f,
		const float	positionEpsilon = 0.001f,
		const float	normalAngleEpsilon = 0.01f,
		const float	texCoordEpsilon = 0.01f
	)

Subdivides all triangles using an ad-hoc algorithm to be described until each edge of every triangle is less than edgeLengthThreshold.

Then merges vertices
