- DreamFusion Text-to-3D using 2D Diffusion (01 Sep 2023)
This is my reading note on DreamFusion: Text-to-3D using 2D Diffusion. This paper proposes a method (score distillation sampling or SDS) to distill a pre-trained text to image diffusion model to a 3D model. The 3D model, which is based on NERF, is trained per text prompt.
- Diff-Instruct A Universal Approach for Transferring Knowledge From Pre-trained Diffusion Models (28 Aug 2023)
This is my reading note on Diff-Instruct: A Universal Approach for Transferring Knowledge From Pre-trained Diffusion Models. The paper explains the theory of using a pre-trained diffusion model to guide the training of a generator model.it shows that both DreamFusion and GAN are a special case of it: score distillation sampling (SDS) from DreamFusion uses Dirac distribution to represent the generator while GAN learns a discriminator to represents the distribution of data. To this end, it proposes IKL, which is tailored for DMs by calculating the integral of the KL divergence along a diffusion process (instead of a single step), which we show to be more robust in comparing distributions with misaligned supports.
- ProlificDreamer High-Fidelity and Diverse Text-to-3D Generation with Variational Score Distillation (20 Aug 2023)
This is my reading note on ProlificDreamer High-Fidelity and Diverse Text-to-3D Generation with Variational Score Distillation. This method proposes variational score sampling to replace score distillation sampling to improve the details of text to image or text to 3D models.

- MeshDiffusion Score-based Generative 3D Mesh Modeling (02 Jul 2023)
This is my reading note for MeshDiffusion: Score-based Generative 3D Mesh Modeling. This paper represents the 3D mesh as a reformed tetrahedral which is defined on a regular 3D grid with 4 channel features: 3D positional deformation of the vertex and signed distance function values to define the surface.
