Samples of the dataset. From top to bottom, there are the RGB, Albedo, Normal and Depth images.

Introduction

G-buffer Objaverse (GObjaverse) is rendered using the TIDE renderer on Objaverse with A10 for about 2000 GPU hours, yielding 30,000,000 images of Albedo, RGB, Depth, and Normal map. We proposed a rendering framework for high quality and high speed dataset rendering. The framework is a hybrid of rasterization and path tracing, the first ray-scene intersection is obtained by hardware rasterization and accurate indirect lighting by full hardware path tracing. Additionally, we using adaptive sampling, denoiser and path-guiding to further speed up the rendering time. In this rendering framework, we render 38 views of a centered object, including 24 views at elevation range from 5° to 30°, rotation = {r × 15° | r ∈ [0, 23]}, and 12 views at elevation from -5° to 5°, rotation = {r × 30° | r ∈ [0, 11]}, and 2 views for top and bottom respectively. In addition, we mannuly split the subset of the objaverse dataset into 10 general categories including Human-Shape (41,557), Animals (28,882), Daily-Used (220,222), Furnitures (19,284), Buildings&&Outdoor (116,545), Transportations (20,075), Plants (7,195), Food (5,314), Electronics (13,252) and Poor-quality (107,001).

Application

We have used G-buffer Objaverse for training MultiView Normal-Depth diffusion model (ND-MV) and depth-condition MultiView Albedo diffusion model (Albedo-MV), which are employed for 3D object generation through score-distillation sampling (SDS) in RichDreamer .
