An OpenGL-Friendly Geometry File Format and its Maya Exporter

Résumé

Despite being the lowest common denominator of CG applications, there is no de facto standard for geometry files. On the contrary, there is a plethora of both proprietary and open formats. One of the many reasons or this state of affairs is that each application has different requirements that are not efficiently compatible. An out-of-core path tracer will have different needs for its geometry-storing solution than a 3D editor or a game. Of course a kitchen-sink approach will offer all the needed features, but probably at the cost of computational and storage efficiency. The goal of this chapter is not to implement the ultimate geometry format. Instead, we will show how to tackle the problem by creating a file format suited to our needs along with the right tools. A file format is pointless without tools for exporting and importing but also for data-mining or conformation. Good tools enable rapid iterations on our asset production pipeline, thus increasing productivity and enabling better artistic impulse.
