public void SetComputeBufferData(ComputeBuffer buffer, Array data);
public void SetComputeBufferData(ComputeBuffer buffer, List<T> data);
public void SetComputeBufferData(ComputeBuffer buffer, NativeArray<T> data);

Parameters

buffer The destination buffer.
data Array of values to fill the buffer.

Description

Adds a command to set the buffer with values from an array.

The input data must follow the data layout rules of the graphics API in use. See Compute Shaders for cross-platform compatibility information.

Note: Because only blittable data types can be copied from the array to the buffer, the array must only contain elements of a blittable type. If you attempt to use non-blittable types, an exception will be raised.

public void SetComputeBufferData(ComputeBuffer buffer, Array data, int managedBufferStartIndex, int graphicsBufferStartIndex, int count);
public void SetComputeBufferData(ComputeBuffer buffer, NativeArray<T> data, int nativeBufferStartIndex, int graphicsBufferStartIndex, int count);
public void SetComputeBufferData(ComputeBuffer buffer, List<T> data, int managedBufferStartIndex, int graphicsBufferStartIndex, int count);

Parameters

buffer The destination buffer.
data Array of values to fill the buffer.
managedBufferStartIndex The first element index in data to copy to the compute buffer.
graphicsBufferStartIndex The first element index in compute buffer to receive the data.
count The number of elements to copy.
nativeBufferStartIndex The first element index in data to copy to the compute buffer.

Description

Adds a command to process a partial copy of data values from an array into the buffer.

The input data must follow the data layout rules of the graphics API in use. See Compute Shaders for cross-platform compatibility information.

Note: Because only blittable data types can be copied from the array to the buffer, the array must only contain elements of a blittable type. If you attempt to use non-blittable types, an exception will be raised.
