论文摘要
尽管最近用于2D图像的生成模型获得了令人印象深刻的视觉结果,但它们显然缺乏执行3D推理的能力。这严重限制了对生成对象的控制程度以及此类模型的可能应用。在这项工作中,我们通过利用最新的可区分渲染进展来弥合这一差距。我们设计了一个框架,该框架仅使用单视自然图像中的2D监督,可以生成三角网格和相关的高分辨率纹理图。我们作品的关键贡献是将网格和纹理作为2D表示的编码,这些表示在语义上是对齐的,并且可以通过2D卷积GAN轻松建模。我们在无条件的设置以及模型在类标签,属性和文本上进行条件的设置中,证明了我们方法对Pascal3D+汽车和CUB的功效。最后,我们提出了一种评估方法,该方法可以分别评估网格和纹理质量。
While recent generative models for 2D images achieve impressive visual results, they clearly lack the ability to perform 3D reasoning. This heavily restricts the degree of control over generated objects as well as the possible applications of such models. In this work, we bridge this gap by leveraging recent advances in differentiable rendering. We design a framework that can generate triangle meshes and associated high-resolution texture maps, using only 2D supervision from single-view natural images. A key contribution of our work is the encoding of the mesh and texture as 2D representations, which are semantically aligned and can be easily modeled by a 2D convolutional GAN. We demonstrate the efficacy of our method on Pascal3D+ Cars and CUB, both in an unconditional setting and in settings where the model is conditioned on class labels, attributes, and text. Finally, we propose an evaluation methodology that assesses the mesh and texture quality separately.
