MeshData

Remarks

The CPU side of MeshDraw. That struct holds buffer handles and a range, because it is read once per object in a frame; this holds arrays, because it is read once per build by something deciding what those buffers should contain.

Parallel arrays, and typed ones. A vertex is not a struct here, because the layout is a compile-time decision — which attributes are present, in what order, at what precision, interleaved or not — and doc 08 puts that in ModelCompiler where the whole model is in hand. Separate arrays let a compiler drop an attribute nothing samples without rewriting the ones it keeps.

An attribute the file did not have is an empty array rather than a null or a defaulted one. Empty says "this mesh has no tangents"; an array of zeros says "this mesh has tangents and they are all degenerate", and a compiler cannot tell the second from a bug in the first.

Fields and properties (20)

• public string Name

  What the mesh is called. Its sub-asset name, and part of its address.

• public Vector3[] Positions

  One position per vertex.

• public Vector3[] Normals

  One normal per vertex, or empty.

• public Vector4[] Tangents

  One tangent per vertex, or empty. W is the bitangent's sign.

• public Vector2[] TexCoords

  One texture coordinate per vertex, or empty.

• public Vector2[] TexCoords1

  A second texture coordinate per vertex, or empty.

• public Vector4[] Colors

  One colour per vertex, or empty. Linear, straight alpha.

• public int[] Indices

  Three indices per triangle.

• public int[] BoneIndices

  Four joint indices per vertex, or empty if the mesh is not skinned.

• public float[] BoneWeights

  Four weights per vertex, summing to one, or empty.

• public int MaterialIndex

  Which of the model's materials this is drawn with.

• public BoundingBox Bounds

  Everything the mesh occupies, in the model's space.

• public AssetReference Clusters

  This mesh's cluster hierarchy and page records, or null if it has none.

• public AssetReference ClusterPages

  Where this mesh's page blob is, or null if it has no clusters.

• public bool IsClustered

  Whether it was built with a cluster hierarchy.

• public int VertexCount

  How many vertices it has.

• public int TriangleCount

  How many triangles it has.

• public bool IsSkinned

  Whether it carries skinning weights.

• public bool HasColors

  Whether it carries per-vertex colours.

• public bool HasTexCoords1

  Whether it carries a second texture coordinate set.
