We propose a hybrid method for computing apparent ridges, expressive lines recently introduced by Judd et al. Unlike their original method, which works entirely over the mesh in object space, our method combines object-space and image-space computations and runs partially on the GPU, taking advantage of modern graphic cards processing power and producing faster results in real time.
