To: Hi Everyone ALL
We are trying to resolve a discrepancy between scenes rendered from within AutoCAD and 3D Studio. The goal is a precise alignment of a rendered image generated from a Digital Terrain Model and a Photograph. The issue has called into question the accuracy of the Camera/FOV in 3D Studio. The problem manifests as an apparent shift in the geometry, suggesting that the FOV relationship to the focal length of the lens is not accurate. What I am looking for is some way to prove the accuracy of the 3DS camera. It seems that there was a discussion about this back in October. Anyone who has any information on the subject of camera/fov accuracy please speak up. At the present time we suspect our methodology in ACAD but would like to subject 3D Studio to a proof first. Thanks for any suggestions or help you may have.
