Extracting Triangular 3D Models, Materials, and Lighting From Images
We learn topology, materials, and environment map lighting jointly from 2D supervision. We directly optimize topology of a triangle mesh, learn materials through volumetric texturing, and leverage differentiable split sum environment lighting. Our output representation is a triangle mesh with spatially varying 2D textures and a high dynamic range environment map, which can be used unmodified in st
GET3D: A Generative Model of High Quality 3D Textured Shapes Learned from Images
We generate a 3D SDF and a texture field via two latent codes. We utilize DMTet to extract a 3D surface mesh from the SDF, and query the texture field at surface points to get colors. We train with adversarial losses defined on 2D images. In particular, we use a rasterization-based differentiable renderer to obtain RGB images and silhouettes. We utilize two 2D discriminators, each on RGB image, an
Instant Neural Graphics Primitives with a Multiresolution Hash Encoding
Neural gigapixel images Neural SDF NeRF Neural volume We demonstrate near-instant training of neural graphics primitives on a single GPU for multiple tasks. In gigapixel image we represent an image by a neural network. SDF learns a signed distance function in 3D space whose zero level-set represents a 2D surface. NeRF [Mildenhall et al. 2020] uses 2D images and their camera poses to reconstruct a
Pixar Universal Scene Description (USD)
What is Universal Scene Description? Universal Scene Description is an extensible framework and ecosystem for describing, composing, simulating, and collaborating within 3D worlds. Originally developed by Pixar Animation Studios, USD, also referred to as OpenUSD, is more than a file format. It’s an open-source 3D scene description used for 3D content creation and interchange among different tools.
