## Detailed Description

General utility class for building edge lists for geometry.

Remarks
  You can add multiple sets of vertex and index data to build and edge list. Edges will be built between the various sets as well as within sets; this allows you to use a model which is built from multiple SubMeshes each using separate index and (optionally) vertex data and still get the same connectivity information. It's important to note that the indexes for the edge will be constrained to a single vertex buffer though (this is required in order to render the edge).

## Constructor & Destructor Documentation

## ◆ EdgeListBuilder()

Ogre::EdgeListBuilder::EdgeListBuilder | ( |  | ) |

## Member Function Documentation

## ◆ addVertexData()

void Ogre::EdgeListBuilder::addVertexData | ( | const VertexData * | vertexData | ) |

Add a set of vertex geometry data to the edge builder.

Remarks
  You must add at least one set of vertex data to the builder before invoking the build method.

## ◆ addIndexData()

void Ogre::EdgeListBuilder::addIndexData | ( | const IndexData * | indexData,
|  | size_t | vertexSet = `0`,
|  | RenderOperation::OperationType | opType = `RenderOperation::OT_TRIANGLE_LIST`
| ) |  |

Add a set of index geometry data to the edge builder.

Remarks
  You must add at least one set of index data to the builder before invoking the build method.

Parameters

  indexData | The index information which describes the triangles.
  vertexSet | The vertex data set this index data refers to; you only need to alter this if you have added multiple sets of vertices
  opType | The operation type used to render these indexes. Only triangle types are supported (no point or line types)

## ◆ build()

EdgeData* Ogre::EdgeListBuilder::build | ( | void |  | ) |

Builds the edge information based on the information built up so far.

Remarks
  The caller takes responsibility for deleting the returned structure.

## ◆ log()

void Ogre::EdgeListBuilder::log | ( | Log * | l | ) |

Debugging method.
