Spherical Harmonic Gradients for Mid-Range Illumination
(The Eurographics Association, 2004)
Spherical harmonics are often used for compact description of incident radiance in low-frequency but distant lighting environments. For interaction with nearby emitters, computing the incident radiance at the center of an ...
Connectivity Transformation for Mesh Metamorphosis
(The Eurographics Association, 2004)
In previous mesh morphing techniques, the vertex set and connectivity of an in-between mesh are fixed and only the vertex positions are interpolated between input meshes. With this restriction, to accurately represent both ...
