Quake MDL feature #1591

Youva · 2024-08-25T17:33:14Z

Adds class vtkQuakeMDLImporter that reads .MDL files.

The class :

Reads vertices and triangle data from the format to display a model.
Reads a texture and texture coordinates from the format to display onto the model.
Reads animations, stored as an array of vertices in the file, and saves them as a vector of polydata.
Groups animations and displays them.
Adds light sources to the scene.

…es. Fixed texture coordinates not rendering correctly by adding more vertices. Fixed camera position and lighting, animations display properly but could still be improved.

Adds support for the .mdl format.

Fixed incorrect type at line 452.

Changed some int variables to size_t.

why adding a camera ?

Probably to correct the actor orientation. Are MDL files +Z up by default? Then you just need to specify it in the config files (improvements of config file is missing by the way).

Nice work @Youva !!
There is still some clean-up to do, especially memory leaks to fix, but they will appear in the CI when you will add a test.
90% of the job is done, and there's the annoying, yet important, finalization left :)
