Hi Sankhesh,
Thanks for your reply.
After doing a bit more homework, I found out that a precise transformation is somewhat more involved than I thought. Especially the article by Wang et al. (Optimal Viewing Angle Determination for Multiple Vessel Segments in Coronary Angiographic Image | IEEE Journals & Magazine | IEEE Xplore) was very helpful. I am currently working on an implementation that involves setting a user matrix on our meshes which combines a perspective projection matrix K with a Rt matrix handling the world to detector transform.
Best regards,
Daan
