Base on GF system,an orthogonal representation algorithm for scattered data is proposed. When k=0 and k=1
GF system are Haar functions and Franklin functions respectively. A new energy model is proposed to solve this problem based on GF system. According to GF spectrum
different hierarchical surfaces could be reconstructed for scattered data. The experiments show that the method proposed is efficient and can produce pleasing results.
