Class BlockInfo

The model obtained from dense reconstruction is represented using a triangular mesh, referred to as a mesh. Since the mesh undergoes frequent updates, to ensure efficiency, the entire reconstructed model's mesh is divided into numerous mesh blocks. A mesh block consists of a cube with a side length of approximately 1 meter, containing elements such as vertices and indices. BlockInfo is used to describe the content of a mesh block. Here, (x,y,z) is the index of the mesh block. Multiplying (x,y,z) by the physical size of each mesh block gives the origin coordinates of this mesh block in the world coordinate system. By using the position of the mesh block in the world, the parts that need to be displayed can be filtered in advance to save rendering time.

The number of vertices contained in a mesh block.

The starting position of vertex data stored in the vertex buffer, indicating from which vertex it belongs to the current mesh block. It is not equal to the byte offset; the offset of the starting position is startPointOfVertex34 bytes.

The number of indices contained in a mesh block, where every three consecutive vertices form a triangular face.

Similar to startPointOfVertex. The starting position of index data stored in the index buffer, indicating from which index it belongs to the current mesh block. It is not equal to the byte offset; the offset of the starting position is startPointOfIndex34 bytes.
int startPointOfIndexint startPointOfIndexpublic int startPointOfIndexpublic Int startPointOfIndex@property (nonatomic) int startPointOfIndexpublic var startPointOfIndex: Int32public int startPointOfIndexversion
The number of times the current mesh block has been updated; a higher version indicates more updates. If the version of a mesh block increases after calling updateSceneMesh, it means that its content has changed.
