  This is a comparative study of the traditional 3D computer graphics technique
of geometric modelling and image-based rendering techniques that were surveyed
and implemented.We have discussed the classifications and representative
methods of both the techniques. The study has shown that there is a strong
continuum between both the techniques and a hybrid of the two is most suitable
for further implementations.This hybridisation study is underway to create
models of real life situations and provide disaster management training.
