Ubisoft Entertainment filed 1 patent this quarter in Graphics.
The filing covers an AI-powered texture compression system that stores high-resolution physically based rendering materials as neural networks directly on GPUs. This approach allows for real-time 4K rendering while reducing video memory requirements.
Ubisoft's single Graphics patent tackles texture compression by replacing traditional mathematical transformations with neural networks trained specifically for each material. Rather than using fixed block compression schemes like BC1 through BC7, the system trains a compact neural network that performs both decompression and trilinear filtering in fewer than 200 GPU operations. The network weights are stored as 16-bit floating point values in GPU buffers, while the underlying latent features still use conventional block compression formats such as BC6 or ASTC. By training end-to-end with backpropagation against a perceptual loss function, the neural approach can identify and compensate for compression artifacts during the learning process, something static compression codecs cannot achieve.
