A Generalizable Light Transport 3D Embedding for Global Illumination

This paper introduces a transformer-based 3D embedding that efficiently approximates global illumination in computer-generated scenes, allowing for generalizable and view-independent rendering without traditional ray tracing. The model learns to encode scene geometry, materials, and lighting into latent codes, which can then be decoded to predict indirect lighting effects, with preliminary results showing potential for complex tasks like glossy reflections and path guiding.

WAN-ANIMATE: UNIFIED CHARACTER ANIMATION AND REPLACEMENT WITH HOLISTIC REPLICATION

This paper introduces Wan-Animate, a new open-source framework for animating and replacing characters in videos, built upon the Wan-I2V model. It uses a modified input paradigm and control signals for body motion and facial expressions to create more realistic and expressive character animations, even outperforming some closed-source commercial products.

LEARNING TO GENERATE 3D SHAPES WITH GENERATIVE CELLULAR AUTOΜΑΤΑ

This paper introduces a new method called Generative Cellular Automata (GCA) to create 3D shapes with a computer. GCA is like building with digital LEGOs, starting with a single block and adding more based on learned rules. It performs well at completing missing parts of shapes and generating entirely new ones, but mainly tests on computer-generated, not real-world, shapes.

A Large-Scale Comparison of Tetrahedral and Hexahedral Elements for Solving Elliptic PDEs with the Finite Element Method

In a surprising upset, quadratic tetrahedral elements performed similarly or better than hexahedral elements for a range of elliptic PDEs, particularly when considering the entire FEM pipeline from meshing to solving. This suggests that robust, automatic tetrahedral meshing, coupled with quadratic elements, can be a strong choice for many common simulation scenarios without sacrificing performance.

Application of Artificial Intelligence in Modern Art Teaching

This paper explores the application of artificial intelligence (AI) in modern art teaching, identifying current limitations and proposing strategies to enhance AI's role. It suggests expanding AI's adaptability, improving intelligent teaching modes, and enriching the artistic experience through personalized learning and virtual reality integration. A performance analysis model based on AHP and grey clustering is introduced to evaluate AI's application effect.
