I present a data-driven method for the real time rendering of deformable objects that accounts for global illumination effects on diffuse surfaces in low frequency lighting conditions. The approach is viable in situations where the space of potential object deformations is known beforehand, so that model appearance information can be pre-computed for a representative sampling of deformation states of the model. Data reduction, primarily via principal component analysis is performed on the pre-computed appearance data to determine a low rank approximation to the complete appearance space. Runtime computation of appearance data for an arbitrary point in appearance space can then be performed in real time in software or on programmable graphics hardware by taking a linear combination of a small number of basis vectors spanning the reduced appearance space.
