Property model

Size: 64 bit / 8 byte (value)
The handle to the model. The model handle is static during its existance. Several models can be opened simultaniously within one session. Different models are always independent, threads are allowed to be running on different models simultaniously.

Property matrix

Size: 32 bit / 4 byte (reference)
The matrix is expected to be nullptr or a 12 element double value allocated by the host (i.e. 96 bytes / 12 doubles). The matrix values are defined column by column as is common for DirectX, OpenGL and VULKAN, i.e. _11, _12, _13, _21, ... _42, _43.
