📝 摘要(中文)

3D物体生成技术已经取得显著进展,但在用户控制方面仍显不足,常常无法满足用户期望,限制了其应用。现有方法主要通过文本指令或2D图像重建3D对象,导致定制化受限并可能引入不必要的伪影。本文提出Interactive3D,一个创新的交互式3D生成框架,允许用户通过丰富的3D交互能力精确控制生成过程。该框架分为两个阶段,第一阶段使用高斯点云实现直接用户交互,第二阶段则通过互动哈希细化模块进一步增强细节和提取几何形状。实验表明,Interactive3D显著提高了3D生成的可控性和质量。

🔬 方法详解

问题定义:本文旨在解决现有3D生成方法在用户控制方面的不足,现有方法通常只能通过文本指令或2D图像进行生成,限制了用户的定制化能力,并可能在3D提升过程中引入伪影。

核心思路:Interactive3D框架的核心思路是通过丰富的3D交互能力,使用户能够在生成的每个中间步骤中进行直接的修改和引导,从而实现更高的可控性和灵活性。

技术框架:Interactive3D框架分为两个阶段。第一阶段使用高斯点云实现用户的直接交互,支持添加、删除组件、可变形和刚性拖动、几何变换及语义编辑。第二阶段将高斯点云转换为InstantNGP,并引入互动哈希细化模块以增强细节和提取几何形状。

关键创新:最重要的技术创新在于引入了互动哈希细化模块,使得在生成过程中用户能够实时调整细节,显著提高了生成的质量和可控性。这一设计与现有方法的本质区别在于提供了更为灵活的用户交互能力。

关键设计:在技术细节上,框架设计了多种交互方式,包括组件的添加和删除、几何变换等,确保用户能够在生成过程中进行多样化的操作。

📄 摘要(原文)

3D object generation has undergone significant advancements, yielding high-quality results. However, fall short of achieving precise user control, often yielding results that do not align with user expectations, thus limiting their applicability. User-envisioning 3D object generation faces significant challenges in realizing its concepts using current generative models due to limited interaction capabilities. Existing methods mainly offer two approaches: (i) interpreting textual instructions with constrained controllability, or (ii) reconstructing 3D objects from 2D images. Both of them limit customization to the confines of the 2D reference and potentially introduce undesirable artifacts during the 3D lifting process, restricting the scope for direct and versatile 3D modifications. In this work, we introduce Interactive3D, an innovative framework for interactive 3D generation that grants users precise control over the generative process through extensive 3D interaction capabilities. Interactive3D is constructed in two cascading stages, utilizing distinct 3D representations. The first stage employs Gaussian Splatting for direct user interaction, allowing modifications and guidance of the generative direction at any intermediate step through (i) Adding and Removing components, (ii) Deformable and Rigid Dragging, (iii) Geometric Transformations, and (iv) Semantic Editing. Subsequently, the Gaussian splats are transformed into InstantNGP. We introduce a novel (v) Interactive Hash Refinement module to further add details and extract the geometry in the second stage. Our experiments demonstrate that Interactive3D markedly improves the controllability and quality of 3D generation. Our project webpage is available at \url{https://interactive-3d.github.io/}.
