BlockInfo Record

Description

The dense reconstructed model is represented by triangle mesh, or simply denoted as mesh. Because mesh updates frequently, in order to ensure efficiency, the mesh of the whole reconstruction model is divided into many mesh blocks. A mesh block is composed of a cube about 1 meter long, with attributes such as vertices and indices.

BlockInfo is used to describe the content of a mesh block. (x, y, z) is the index of mesh block, the coordinates of a mesh block's origin in world coordinate system can be obtained by multiplying (x, y, z) by the physical size of mesh block. You may filter the part you want to display in advance by the mesh block's world coordinates for the sake of saving rendering time.

x

x in index (x, y, z) of mesh block.

C: int x

y

y in index (x, y, z) of mesh block.

numOfVertex

Number of vertices in a mesh block.

C: int numOfVertex

C++11: int numOfVertex

Traditional C++: int numOfVertex

Java: public int numOfVertex

Kotlin: public Int numOfVertex

Objective-C: @property (nonatomic) int numOfVertex

Swift: public var numOfVertex: Int32

C#: public int numOfVertex

startPointOfVertex

startPointOfVertex is the starting position of the vertex data stored in the vertex buffer, indicating from where the stored vertices belong to current mesh block. It is not equal to the number of bytes of the offset from the beginning of vertex buffer. The offset is startPointOfVertex*3*4 bytes.

C: int startPointOfVertex

C++11: int startPointOfVertex

Traditional C++: int startPointOfVertex

Java: public int startPointOfVertex

Kotlin: public Int startPointOfVertex

Objective-C: @property (nonatomic) int startPointOfVertex

Swift: public var startPointOfVertex: Int32

C#: public int startPointOfVertex

numOfIndex

The number of indices in a mesh block. Each of three consecutive vertices form a triangle.

C: int numOfIndex

C++11: int numOfIndex

Traditional C++: int numOfIndex

Java: public int numOfIndex

Kotlin: public Int numOfIndex

Objective-C: @property (nonatomic) int numOfIndex

Swift: public var numOfIndex: Int32

C#: public int numOfIndex

startPointOfIndex

Similar to startPointOfVertex. startPointOfIndex is the starting position of the index data stored in the index buffer, indicating from where the stored indices belong to current mesh block. It is not equal to the number of bytes of the offset from the beginning of index buffer. The offset is startPointOfIndex*3*4 bytes.

C: int startPointOfIndex

C++11: int startPointOfIndex

Traditional C++: int startPointOfIndex

Java: public int startPointOfIndex

Kotlin: public Int startPointOfIndex

Objective-C: @property (nonatomic) int startPointOfIndex

Swift: public var startPointOfIndex: Int32

C#: public int startPointOfIndex

version

Version represents how many times the mesh block has updated. The larger the version, the newer the block. If the version of a mesh block increases after calling DenseSpatialMap.updateSceneMesh , it indicates that the mash block has changed.

C: int version

C++11: int version

Traditional C++: int version

Java: public int version

Kotlin: public Int version

Objective-C: @property (nonatomic) int version

Swift: public var version: Int32

C#: public int version
