* `Geom.Mesh.GenerateObjVerts` is a new function that will generate a series of `Vertex` objects based on the given parsed Wavefront Obj Model data. You can optionally scale and translate the generated vertices and add them to a Mesh. * `Geom.Mesh.GenerateObjVerts` is a new function that will generate a series of `Vertex` objects based on the given parsed Wavefront Obj Model data.

* `Geom.Mesh.ParseObj` is a new function that will parse a triangulated Wavefront OBJ file into model data into a format that the `GenerateObjVerts` function can consume. * `Geom.Mesh.ParseObj` is a new function that will parse a triangulated Wavefront OBJ file into model data into a format that the `GenerateObjVerts` function can consume.
* `Geom.Mesh.ParseObjMaterial` is a new function that will parse a Wavefront material file and extract the diffuse color data from it, combining it with the parsed object data. * `Geom.Mesh.ParseObjMaterial` is a new function that will parse a Wavefront material file and extract the diffuse color data from it, combining it with the parsed object data.
* `Geom.Mesh.RotateFace` is a new function that will rotate a Face by a given amount, based on an optional center of rotation.
* `Loader.OBJFile` is a new File Loader type that can load triangulated Wavefront OBJ files, and optionally material files, which are then parsed and stored in the OBJ Cache. * `Loader.OBJFile` is a new File Loader type that can load triangulated Wavefront OBJ files, and optionally material files, which are then parsed and stored in the OBJ Cache.
* The Mesh constructor and `MeshFactory` signatures have changed to `scene, x, y, texture, frame, vertices, uvs, indicies, containsZ, normals, colors, alphas`. Note the way the Texture and Frame parameters now comes first. `indicies` is a new parameter that allows you to provide indexed vertex data to create the Mesh from, where the `indicies` array holds the vertex index information. The final list of vertices is built from this index along with the provided vertices and uvs arrays. The `indicies` array is optional. If your data is not indexed, then simply pass `null` or an empty array for this parameter. * The Mesh constructor and `MeshFactory` signatures have changed to `scene, x, y, texture, frame, vertices, uvs, indicies, containsZ, normals, colors, alphas`.

* The `Mesh` Game Object now has the Animation State Component. This allows you to create and play animations across the texture of a Mesh, something that previously wasn't possible. As a result, the Mesh now adds itself to the Update List when added to a Scene. * The `Mesh` Game Object now has the Animation State Component.

* `Mesh.getFaceAt` new is a new method that will return an array of Face instances from the Mesh based on the given position. The position is checked against each Face, translated through the optional Camera and Mesh matrix. If more than one Face intersects, they will all be returned but the array will be depth sorted first, so the first element will be that closest to the camera. * `Mesh.getFaceAt` new is a new method that will return an array of Face instances from the Mesh based on the given position.

* `Mesh.faces` is a new array of `GameObject.Face` instances, which is populated during a call to methods like `addVertices` or `addModel`. * `Mesh.faces` is a new array of `GameObject.Face` instances, which is populated during a call to methods like `addVertices` or `addModel`.
* `Mesh.totalRendered` is a new property that holds the total number of Faces that were rendered in the previous frame.
* `Mesh.setDebug` is a new method that allows you to render a debug visualisation of the Mesh vertices to a Graphics Game Object. You can provide your own Graphics instance and optionally callback that is invoked during rendering. This allows you to easily visualise the vertices of your Mesh to help debug UV mapping. * `Mesh.setDebug` is a new method that allows you to render a debug visualisation of the Mesh vertices to a Graphics Game Object. You can provide your own Graphics instance and optionally callback that is invoked during rendering. This allows you to easily visualise the vertices of your Mesh to help debug UV mapping.
* The Mesh now renders by iterating through the Faces array, not the vertices. This allows you to use Array methods such as `BringToTop` to reposition a Face, thus changing the drawing order without having to repopulate all of the vertices. Or, for a 3D model, you can now depth sort the Faces. * The Mesh now renders by iterating through the Faces array, not the vertices.

* The `Mesh` Game Object now extends the `SingleAlpha` component and the alpha value is factored into the final alpha value per vertex during rendering. This means you can now set the whole alpha across the Mesh using the standard `setAlpha` methods. But, if you wish to, you can still control the alpha on a per-vertex basis as well. * The `Mesh` Game Object now extends the `SingleAlpha` component and the alpha value is factored into the final alpha value per vertex during rendering.
