Detailed Description

AttachmentImage is intended for use, primarily, as an attachment on a pass. Image data can be produced by the GPU or uploaded directly from CPU data. Use this class to represent color / depth stencil targets, read-write images, etc.

◆ Create()

static Data::Instance<AttachmentImage> AZ::RPI::AttachmentImage::Create ( const AttachmentImagePool imagePool,
const RHI::ImageDescriptor imageDescriptor,
const Name &  imageName,
const RHI::ClearValue optimizedClearValue = nullptr,
const RHI::ImageViewDescriptor imageViewDescriptor = nullptr 
)
static

Creates an AttachmentImage

Parameters
imagePoolThe attachment image pool which the AttachmentImage is created from
imageDescriptorThe ImageDescriptor for this AttachmentImage
imageNameThe name of this image. It will be used as RHI object name (for gpu debug).
optimizedClearValue(Optional) set the default clear value for this image
imageViewDescriptor(Optional) The imageViewDescriptor for this image which overides the default ImageViewDescriptor.
