示例1: vkUpdateDescriptorSets
//.........这里部分代码省略.........
ref = eFrameRef_Read;
break;
case VK_DESCRIPTOR_TYPE_STORAGE_IMAGE:
case VK_DESCRIPTOR_TYPE_STORAGE_TEXEL_BUFFER:
case VK_DESCRIPTOR_TYPE_STORAGE_BUFFER:
case VK_DESCRIPTOR_TYPE_STORAGE_BUFFER_DYNAMIC:
ref = eFrameRef_Write;
break;
default:
RDCERR("Unexpected descriptor type");
}
// We need to handle the cases where these bindings are stale:
// ie. image handle 0xf00baa is allocated
// bound into a descriptor set
// image is released
// descriptor set is bound but this image is never used by shader etc.
//
// worst case, a new image or something has been added with this handle -
// in this case we end up ref'ing an image that isn't actually used.
// Worst worst case, we ref an image as write when actually it's not, but
// this is likewise not a serious problem, and rather difficult to solve
// (would need to version handles somehow, but don't have enough bits
// to do that reliably).
//
// This is handled by RemoveBindFrameRef silently dropping id == ResourceId()
