About DreamFusion

DreamFusion is an AI tool that utilizes a text-to-image generative model called Imagen to optimize 3D scenes. The tool incorporates Score Distillation Sampling (SDS), which enables the generation of samples from a diffusion model by optimizing a loss function. SDS allows for the optimization of samples in a 3D space or any other arbitrary parameter space. The product employs a 3D scene parameterization similar to Neural Radiance Fields to define a differentiable mapping. DreamFusion features additional regularizers and optimization strategies to enhance geometry, resulting in coherent, high-quality normals, surface geometry, depth, and relightable NeRFs with a Lambertian shading model. DreamFusion is ideal for optimizing 3D scenes for various applications, such as video games, virtual reality experiences, and film production.
