The vertex delta model, which uses a GPU based neural network. This model acts more as an example of how to implement a model that only uses the GPU. It is not as efficient as the Neural Morph Model, even though that model runs on the CPU. Unlike the Neural Morph Model this Vertex Delta Model does not generate any morph targets. All the vertex deltas are directly output by the neural network. This buffer of output deltas remains on the GPU and is then used as input buffer directly inside an optimus deformer graph.
