Illumination-dependent texture

In this paper, we propose an image-based texture model called IlluminationDependent Texture(IDT), for realisticly rendering objects covered with 3D texture under low-frequency illumination. A framework of IDT is presented, which includes acquisition, analysis, synthesis and rendering. After sampling 3D texture images, we analyze samples based on spherical harmonics. Then the IDT samples could be synthesized on arbitrary surface. Before rendering, we take preprocesses for IDT coordinate transformation and illumination analysis. Then a simple rendering process could be performed in real-time under low-frequency natural environment illumination, or under simple lighting(parallel lighting or point lights). Finally, we demonstrate several IDT rendering examples with real-world and synthetic textures.
