New methods accelerate Heat Kernel Textures computation

Researchers have developed two novel methods to accelerate the computation of Heat Kernel Textures (HKTex), a technique used for representing surface appearance. The first method, LocalHK, replaces spectral evaluation with local unfolding and an analytic log-map kernel, significantly reducing initialization time and enabling larger mesh processing. The second method, ThermalRF, uses randomized range finding and Chebyshev actions to construct global low-rank heat factors without mesh-sized eigenvectors, leading to reduced end-to-end preprocessing and optimization times while maintaining high fidelity.
