Unigine.StructuredBuffer Class
StructuredBuffer is a buffer for structures: it represents a uniform array of structures.
StructuredBuffer resource can specified via the following flags:
- USAGE_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.
- USAGE_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.
- USAGE_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.
- USAGE_STAGING specifies a resource that supports direct data transfer from the GPU to CPU.
- USAGE_SHARED specifies that a resource is accessible by an external graphics API.

StructuredBuffer Class
Properties
string DebugName#
The friendly name of the structured buffer used 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.
int NumElements#
The number of elements in the structured buffer.
bool IsUsageShared#
The value indicating if the resource has the USAGE_SHARED flag enabled.
bool IsUsageStaging#
The value indicating if the resource has the USAGE_STAGING flag enabled.
bool IsUsageCPUResource#
The value indicating if the resource has the USAGE_CPU_RESOURCE flag enabled.
bool IsUsageImmutable#
The value indicating if the resource has the USAGE_IMMUTABLE flag enabled.
bool IsUsageGPUResource#
The value indicating if the resource has the USAGE_GPU_RESOURCE flag enabled.
