In Virtual Reality (VR) and computer graphic fields, 3-dimension (3D) matter modeling has been developed for many years and successfully applied to many fields. However, researches on 3D energy field modeling are still not enough owing to challenges of full understanding and real-time calculation of invisible energy fields. In the visual information world, energy field modeling is becoming a new research point and should promote relevant research advancement and widen applications. In the paper, after reviewing the 3D object modeling, light field modeling is addressed from three aspects which contain light propagation characteristic, bidirectional reflectance distribution function (BRDF), sunlight transfer process between solar source and observers. Especially the quantitative radiances at ground level and aircraft/space level are presented. According to the sunlight transfer process, a research framework of Remote Sensing Image Simulation (RSIS) is proposed and an experiment is implemented. Our study shows that light field modeling can make invisible energy fields easily-understood and demonstrate an example of multi-sciences integration research.
