颠覆3D建模！GGHead ：实现超高速高质量、角色一致3D头部生成
本文来聊一聊一种新颖的3D 建模技术 ——GGHead。这个技术由慕尼黑工业大学的 Tobias Kirschstein 等人研发，能够在超快的速度下生成高质量、视角一致的3D 人头模型。想象一下，使用普通的消费级 GPU，GGHead 可以实时生成和渲染分辨率达到1024² 的3D 头部图像，这在以往是难以实现的。GGHead 的核心在于它采用了一种叫做 “3D 高斯点云” 的表示方式，结合了3D 生成对抗网络（GAN）的优势。它通过一个强大的2D 卷积神经网络(CNN)来预测模板头部网格在 UV 空间中的高斯属性。这样，GGHead 就可以充分
