The DepthWrite field is a member of the ResourceState enumeration within the Sandbox.Rendering namespace. It represents a specific state of a GPU resource where depth writing is enabled. This state is typically used when rendering operations require writing to the depth buffer, which is essential for depth testing and ensuring correct rendering order of objects in 3D space.
Use the DepthWrite state when you need to transition a resource to a state where it can write to the depth buffer. This is commonly used in rendering pipelines where depth testing is necessary to determine the visibility of objects based on their distance from the camera.
// Example of using ResourceState.DepthWrite in a rendering pipeline
void SetupRenderingPipeline()
{
// Assume 'resource' is a GPU resource that needs to be transitioned
// to a depth write state for rendering operations.
TransitionResourceState(resource, ResourceState.DepthWrite);
// Perform rendering operations that require depth writing
RenderScene();
// Transition the resource back to a common state after rendering
TransitionResourceState(resource, ResourceState.Common);
}
void TransitionResourceState(Resource resource, ResourceState newState)
{
// Implementation for transitioning the resource state
// This would typically involve setting up a barrier or similar mechanism
