Function Documentation

◆ dwPointCloud_createBuffer()

DW_API_PUBLIC dwStatus dwPointCloud_createBuffer ( dwPointCloud * buffer )

Allocates memory for point cloud data structure.

Parameters

[out] buffer Pointer to dwPointCloud

Returns: DW_SUCCESS
DW_INVALID_ARGUMENT

Note

User must specify the followings for the argument buffer:

The member variable capacity to indicate the memory allocation size
The member variable type to indicate the memory type, either host memory or device memory

Upon successful return, this API will set size to zero to indicate it contains no element in the memory By default this API will set organized to false

◆ dwPointCloud_destroyBuffer()

DW_API_PUBLIC dwStatus dwPointCloud_destroyBuffer ( dwPointCloud * buffer )

Destroys allocated memory for point cloud data structure.
