Two Minute Papers - NVIDIA Unveils AI For 150x Faster 3D Modeling!
NVIDIA has introduced a groundbreaking AI technique called InstantSplat, which can generate a fully immersive 3D model from just three photos. This represents a significant advancement over previous methods, which struggled to produce clear images due to insufficient data. InstantSplat synthesizes the missing information, creating high-quality 3D models in seconds. This technique is not only faster but also more accurate, capturing complex visual effects like specular reflections that require an understanding of material properties. Users can try this technology by uploading their images, and it even works with unposed photos, making it highly accessible. The method is based on Gaussian Splatting, which efficiently represents surfaces with minimal data storage. While it excels at modeling surfaces, it is less effective for volumetric objects like smoke. However, complementary research is addressing these limitations with advanced light transport simulations. The technology is available for free, offering immense potential for applications in gaming and virtual reality.
