We would like to make our own fantasy cuts to use in the Helium Rough / PACOR software. What should we do?
In order to create your own DLL cuts you need the developing environment allowing to compile the DLL modules. Our DLL cut samples are created with Microsoft Visual C++ compiler. So we strongly recommend this tool to use our samples as a start-up template.
The DLL samples with the source codes and documentation are available here. See in section Create your own DLL: Pear External Cut sample and Parallelepiped External Cut sample.
Of course creating an external DLL cut implies a kind of 3D/mathematics work, like draw 3D-model and define the position and movements of all vertex and sides dependent from the parameters values, and programming work.
