Currently all the tools are implemented in a modular fashion where in each tool is accessed as a module. The primitive task of this project is to combine the image processing functionalities of these tools to a library. This task will ensure the reusability of these functionalities by the application programmer through relevant api calls in the code and thus will be useful for building a proper GUI for BRL-CAD and helpful in other new tools/functions to be added to BRL-CAD in future. |

Apart from the other formats, it has support for the BRL-CAD pioneered '''.pix''' format and the unix plots. Thus BRL-CAD cannot use any other third party library for Image Processing without altering them. Therefore work is underway in strengthening and Consolidating BRL-CAD’s image Processing Library and adding various Image Processing functionalities in it. |
