Camera transformations in Gocad : local magnifying glasses.

@inproceedings{caumon_3,
 abstract = { A new visualization tool is proposed to improve the understanding of thin and wide subsurface
models. A transformation, defined at the beginning of the graphic rendering pipeline, allows to
get, locally, a closer view of the model, as if a magnifying glass was placed between the user and
the model. The continuity between the magnified zone and the untouched part of the scene, which
induces deformations, is handled by the transformation. Compared to a global scaling, this method
does not introduce significant bias in the view of the model. },
