Struct BlockInfo

Assembly

EasyAR.Sense.dll

The model obtained through 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 partitioned into numerous mesh blocks. A mesh block consists of a cube with an edge length of approximately 1 meter, containing elements such as vertices and indices.

 BlockInfo describes the content of a mesh block. The (x,y,z) values represent the indices of the mesh block. Multiplying (x,y,z) by the physical size of each mesh block yields the origin coordinates of this mesh block in the world coordinate system. The required display sections can be pre-filtered based on the position of the mesh block in the world to save rendering time.

Constructors

BlockInfo(int, int, int, int, int, int, int, int)

public BlockInfo(int x, int y, int z, int numOfVertex, int startPointOfVertex, int numOfIndex, int startPointOfIndex, int version)

Parameters

x

y

z

numOfVertex

startPointOfVertex

numOfIndex

startPointOfIndex

version

Fields

numOfIndex

The number of indices contained within a mesh block. Every three consecutive indices form a triangular face.

public int numOfIndex

Field Value

numOfVertex

The number of vertices contained within a mesh block.

public int numOfVertex

Field Value

startPointOfIndex

Similar to startPointOfVertex. The starting position of the index data within the index buffer, indicating the index at which indices belonging to the current mesh block begin. This is not equivalent to the byte offset; the byte offset of the starting position is startPointOfIndex*3*4 bytes.

public int startPointOfIndex

Field Value

startPointOfVertex

The starting position of the vertex data within the vertex buffer, indicating the index at which vertices belonging to the current mesh block begin. This is not equivalent to the byte offset; the byte offset of the starting position is startPointOfVertex*3*4 bytes.

public int startPointOfVertex

Field Value

version

The update count for the current mesh block; a higher version number indicates more frequent updates. If a mesh block's version increases after calling `DenseSpatialMap.updateSceneMesh`_, it signifies that its content has changed.

public int version

Field Value

x

The x-coordinate in the mesh block's index (x,y,z).

public int x

Field Value

y

The y-coordinate in the mesh block's index (x,y,z).

public int y

Field Value

z

The z-coordinate in the mesh block's index (x,y,z).

public int z

Field Value
