顛覆3D建模！GGHead ：實現超高速高質量、角色一致3D頭部生成
本文來聊一聊一種新穎的3D 建模技術 ——GGHead。這個技術由慕尼黑工業大學的 Tobias Kirschstein 等人研發，能夠在超快的速度下生成高質量、視角一致的3D 人頭模型。想象一下，使用普通的消費級 GPU，GGHead 可以實時生成和渲染分辨率達到1024² 的3D 頭部圖像，這在以往是難以實現的。GGHead 的核心在於它採用了一種叫做 “3D 高斯點雲” 的表示方式，結合了3D 生成對抗網絡（GAN）的優勢。它通過一個強大的2D 卷積神經網絡(CNN)來預測模板頭部網格在 UV 空間中的高斯屬性。這樣，GGHead 就可以充分
