As a new implementation, our dynamic ray tracing needs some tests to prove its accuracy. The first synthetic model is designed for this purpose. It is a linear velocity model. We can get theoretical solution for this model. The second model is a two-layered model. We use this model to show the importance of smoothing the model. We also show the change of amplitude caused by the interface between the two layers. The third one is a synthetic saltdome model, which is issued by EAEG/SEG velocity modeling committee. This model is much more complicated and therefore presents a real challenge. The result from this model also demonstrates the effectiveness of our approach.

- Synthetic model (linear velocity)
- Synthetic model (two layers, velocity within each layer is constant)
- EAEG/SEG saltdome model
