This paper aims at achieving high-fidelity 3D-aware images synthesis. We propose a novel framework, termed as VolumeGAN, for synthesizing images under different camera views, through explicitly learning a structural representation and a textural representation. We first learn a feature volume to represent the underlying structure, which is then converted to a feature field using a NeRF-like model. The feature field is further accumulated into a 2D feature map as the textural representation, followed by a neural renderer for appearance synthesis. Such a design enables independent control of the shape and the appearance. Extensive experiments on a wide range of datasets show that our approach achieves sufficiently higher image quality and better 3D control than the previous methods.

Qualitative Results

Independent control of structure (shape) and texture (appearance).

    This is totally not runable.

    And there is a typo in here: https://github.com/genforce/volumegan/blob/21110dcc85f01a96156b0042c7e604d08ea911e7/render.py#L198

    Finally I would like to ask if the training code has been tested?
