The GetData method retrieves data from the GPU buffer and stores it in the provided System.Span<T>. This method is useful for accessing the data processed on the GPU and bringing it back to the CPU for further operations or analysis.
The GetData method retrieves data from the GPU buffer and stores it in the provided System.Span<T>. This method is useful for accessing the data processed on the GPU and bringing it back to the CPU for further operations or analysis.
To use the GetData method, you need to have a GpuBuffer instance and a System.Span<T> where the data will be stored. Ensure that the span is appropriately sized to hold the data being retrieved from the GPU buffer.
// Define a data structure
struct MyData
{
public float Value;
}
// Create a GPU buffer with a specific number of elements
using (var buffer = new GpuBuffer<MyData>(8))
{
// Pass the buffer to a compute shader
ComputeShader.Attributes.Set("myData", buffer);
// Dispatch the shader to process data
ComputeShader.Dispatch();
// Prepare a span to receive data from the GPU
Span<MyData> dataSpan = new MyData[8];
// Retrieve the data from the GPU buffer
buffer.GetData(dataSpan);
// Now dataSpan contains the data processed by the GPU
