When simulating reservoir data in the oil industry
the eclipse format is often used to store both the results of and the model for the simulation. This format however is not very well suited for visualization,
because among other features it includes redundant
information and stores the data in non-regular grids.
This has implications with regards to the time and
space required to simplify the polygonal representation of each channel (reduce number of faces and vertices) and remove artifacts such as overlapping faces.
To solve this problem we have developed a method
which simplifies the polygonal representation of the
eclipse-data and stores the result as wavefront objects. The theoretical complexity of this algorithm
has been found and the real-world difference in running time, storage usage and result has been compared to a simple conversion which does not simplify
and does not remove artifacts. The results were good,
with up to larger than 90% removal of faces and vertices. As well as a removal of most visual artifacts.
