* Vulkan Example - Multisampling using resolve attachments (MSAA)
|
|
|
|
|
*
|
|
|
|
|
* This sample shows how to do multisampled anti aliasing using built-in hardware via resolve attachments
|
|
|
|
|
* These are special attachments that a multi-sampled is resolved to using a fixed sample pattern
