Description
Cette macro exporte votre object pour être visionné dans le programme de raytracing Kerkythea.
Utilisation
Vous pouvez télécharger le fichier sur github à l'adresse FreeCAD to Kerkythea-Exporter
C'est assez explicite. Pour l'instant, il y a des problèmes avec l'exportation des lumières et de la position de la caméra.
