Texture Generation Using Graph Generative Adversarial Network And Differentiable Rendering.

Novel texture synthesis for existing 3D mesh models is an important step towards photo realistic asset generation for existing simulators. But existing methods inherently work in the 2D image space which is the projection of the 3D space from a given camera perspective. These methods take camera angle, 3D model information, lighting information and generate photorealistic 2D image. To generate a photorealistic image from another perspective or lighting, we need to make a computationally expensive forward pass each time we change the parameters. Also, it is hard to generate such images for a simulator that can satisfy the temporal constraints the sequences of images should be similar but only need to change the viewpoint of lighting as desired. The solution can not be directly integrated with existing tools like Blender and Unreal Engine. Manual solution is expensive and time consuming. We thus present a new system called a graph generative adversarial network (GGAN) that can generate textures which can be directly integrated into a given 3D mesh models with tools like Blender and Unreal Engine and can be simulated from any perspective and lighting condition easily.
