The UnorderedAccess field is a member of the ResourceState enumeration within the Sandbox.Rendering namespace. It represents a state where a resource can be accessed in an unordered manner, allowing for read and write operations without a specific order. This is typically used for resources that are accessed by compute shaders or other operations that require random access.
Use the UnorderedAccess state when you need to perform unordered read and write operations on a resource. This is common in scenarios involving compute shaders where the order of access does not need to be sequential.
// Example of setting a resource state to UnorderedAccess
ResourceState currentState = ResourceState.UnorderedAccess;
// Use this state when configuring a resource barrier
// This is typically done when setting up a compute shader
// or when you need to perform random read/write operations
// Example usage in a resource barrier setup
ResourceBarrier barrier = new ResourceBarrier
{
StateBefore = ResourceState.Common,
StateAfter = ResourceState.UnorderedAccess,
Resource = myResource
};
// Apply the barrier to transition the resource state
GraphicsDevice.TransitionResource(barrier);
