Mesh class is a container and provides an interface for mesh loading, manipulating and saving.

By using this class, you can create a mesh, add geometry to it (e.g. box, plane, capsule or cylinder surface), add animations and bones (if you want to create a skinned mesh) and then use it to create the following objects:

Also you can get geometry of all of these objects via the Mesh class.

Features of the mesh are listed below:

Each surface of the mesh supports several morph targets.
Each surface has a quaternion-based tangent basis for the better loading speed.
8-bit vertex colors are supported.
Each vertex of a surface has 2 sets of indices: coordinate and triangle indices. It improves the loading speed and reduces data duplication.
Each vertex of a surface has 2 UV sets.
A bind pose transformation is stored for each mesh (even if there are no animations and animation frames). See also the getBoneTransfroms() method.
Notice
The 1st animation frame should not contain the bind pose.

Vertex Data and Indices

Each surface of the mesh consists of triangles, and each triangle has 3 vertices. Thus, for each mesh surface we have:

Total number of vertices = 3 * number of triangles.

If a vertex belongs to several triangles, we have to store several copies of such vertex. Each of these copies would store information about position, normal, binormal, tangent and texture coordinates. In order to reduce data duplication and increase loading speed UNIGINE uses the optimization described below.

There are 2 separate vertex data buffers are used:

CVertices coordinate buffer, which stores only vertex coordinates.
TVertices triangle buffer, which stores vertex attributes such as normal, binormal, tangent, color, UV coordinates.

On the picture below, arrows are used to show normals:

Surface that contains 2 adjacent triangles. Here C0...C3 are coordinate vertices, T0...T5 are triangle vertices

The coordinate buffer is an array of coordinate vertices. For example, the coordinate buffer for the surface presented on the picture above is the following:

Output

CB = [C0,C1,C2,C3]

Each coordinate vertex contains coordinates ( float[3]) of the vertex.

Notice

The number of vertices and coordinate vertices is the same.

The triangle buffer is an array of triangle vertices. For example, the triangle buffer for the surface presented on the picture above is the following:

Output

TB = [T0,T1,T2,T3,T4,T5]

Each triangle vertex can store:

Normal
Binormal
Tangent
1st UV map texture coordinates
2nd UV map texture coordinates
Color

Notice

The number of vertices and triangle vertices can be different.

The number of triangle vertices depends on the number of triangles, to which the vertex belongs. For example, if 2 triangles have 1 adjacent vertex with different normals for each triangle, 2 triangle vertices will be stored (the 1st and the 3rd vertices on the picture above). However, if the components are the same for all of the adjacent triangles, only 1 triangle vertex will be stored.

Both the coordinate and triangle vertices have indices. There are 2 index buffers to get proper cvertex and tvertex data for each vertex of mesh surface:

CIndices buffer — coordinate indices, which are links to CVertices data.
TIndices buffer — triangle indices, which are links to TVertices data.

The number of elements in these index buffers is equal to the total number of vertices of a mesh surface.

Coordinate Indices

Each vertex of a mesh surface has a coordinate index - a number of the corresponding element of the coordinate buffer, where the data is stored. For the given surface the array of the coordinate indices is as follows:

Output

CIndices = [Ci0,Ci1,Ci3,Ci1,Ci2,Ci3]

Here:

The first 3 elements are the coordinate indices of the first (bottom) triangle.
The second 3 elements are the coordinate indices of the second (top) triangle.

Triangle Indices

Each vertex of a mesh surface also has a triangle index - a number of the corresponding element of the triangle buffer, where the data is stored. For the given surface the array of the triangle indices is as follows:

Output

TIndices = [Ti0,Ti1,Ti5,Ti2,Ti3,Ti4]

Here:

The first 3 elements are the triangle indices of the first (bottom) triangle.
The second 3 elements are the triangle indices of the second (top) triangle.

Notice

The number of the coordinate and triangle indices is the same.
