e the existing text-to-image diffusion models such as Stable Diffusion which only generates an image. With almost the same number of parameters, LDM3D achieves to create a latent space that can compress both the RGB images and the depth maps. Two checkpoints are available for use: ldm3d-original. The original checkpoint used in the paper ldm3d-4c. The new version of LDM3D using 4 channels inputs instead of 6-channels inputs and finetuned on hig
