Unigine.StructuredBuffer Class
StructuredBuffer is a buffer for structures: it represents a uniform array of structures.
StructuredBuffer resource can specified via the following flags:
- GPU_RESOURCE specifies a resource that can be read and written by the GPU. It also creates a temporary direct staging buffer to copy the data from the main buffer and gets the data by the CPU.
- IMMUTABLE specifies a resources that can only be read by the GPU. It also creates a temporary direct staging buffer to copy the data from the main buffer and gets the data by the CPU.
- CPU_RESOURCE specifies a resource that is accessible by both the GPU (read only mode) and the CPU (write only mode). It also creates a temporary direct staging buffer to copy the data from the main buffer and gets the data by the CPU.
- STAGING specifies a resource that supports direct data transfer from the GPU to CPU.

StructuredBuffer Class
Properties
string DebugName#
Friendly name of the structured buffer used for GPU debugging (RenderDoc, NVIDIA Nsight).
set
Sets a friendly name for GPU debugging (RenderDoc, NVIDIA Nsight). It can be used to help you determine if the corresponding object interface pointer caused the leak. Memory leaks are reported by the debug software layer by outputting a list of object interface pointers along with their friendly names.
set value -
Friendly debug name to be set.
