<div dir="ltr">Hello vtkusers,<div><br></div><div style>I'm trying to position and orient a vtkCamera to model an X-Ray camera as shown in the figure below.</div><div style><br></div><div style><img src="cid:ii_13e19d34a9887059" alt="Inline image 1"><br>
</div><div style><br></div><div style>I'm running into uses so I just want to make sure this is fundamentally possible with a vtkCamera. I know:</div><div style><br></div><div style> - Position and orientation of the camera coordinate system (red axes) in world space</div>
<div style> - X-Ray point source (green point)</div><div style> - Principal point (purple point)</div><div style> - The width, d, of the square detector (and therefore the view angle)</div><div style><br></div><div style>
(1) Can I place Props between the camera Position and FocalPoint?</div><div style><br></div><div style><div>(1a) If so, how should the Position and FocalPoint be set?</div><div><div><br></div><div>(1a) If not, is there another approach to set the Position/FocalPoint/ViewUp to simulate this?</div>
</div><div><br></div></div><div style>Thanks!</div><div style>Taylor</div></div>
