[Opensg-users] a question about orthographics projection

[Kitty Tang]

Hello, My projection needs orthographic projection. i have checked and only find perspective projection is used. Does Opensg support also Or.projection?  how to set up and how to use?   I find in camera class, a function called setupProjection(DrawActionBase *action, const Viewport &port) is this function helpful for this?   Many thanks   Best regars Kitty
