| 英文摘要 | In this paper, we present a new sh operation, called spherical harmonics scaling, to shrink or expand a spherical function in the frequency domain. we show that this problem can be elegantly formulated as a linear transformation of sh projections, which is efficient to compute and easy to implement on a gpu. spherical harmonics scaling is particularly useful for extrapolating visibility and radiance functions at a sample point to points closer to or farther from an occluder or light source. with sh scaling, we present applications to low-frequency shadowing for general deformable object, and to efficient approximation of spherical irradiance functions within a mid-range illumination environment. |
