Does Vulkan have TransformFeedback equivalent

Question

Does Vulkan have support for saving vertices from the pipeline stage? I searched and I can not find any examples or links, maybe someone else knows otherwise?

Answer 1

Transform Feedback did not make a cut for the initial release of Vulkan, and there is no direct equivalent to it.

So you really need to do this yourself, for example. writing SSBOs from a geometric shader using PrimitiveID, or go to computational shaders.

Please note that the geometry shader version may not work on all devices, as it requires support for the vertexPipelineStoresAndAtomics function .
