<body class='hmmessage'><div dir='ltr'>I have a need to interactively scroll through a 3d surface (similar to a digital elevation map) - where camera is 'looking downward', where the camera is orthogonal to the plane surface, and where a color map is assigned to the 'elevation' in the 3d surface. <div><br></div><div>given that the vtk gui may be interactively zoomed in and out, and that where the camera is viewing may be changed, etc...<div><br></div><div>is there any ability for me to say, 'i like this specific view of the data set i am now seeing - i need to save the state of this exact viewing situation' (eg, something akin to taking a snapshot not of the bitmapped pixcelated screen - but rather of the entire state of the vtk environment at that point in time). </div><div><br></div><div>my aimpoint here is to save several such 'states' in a format that would allow me, to at a later point in time, open this same data set in my same vtk application - and then be able to see the EXACT SAME vtk 'snapshot states' that i earlier found to be interesting.</div><div><br></div><div>im not a doctor, but suppose such an application might be so that a doctor making an assessment of a 3d medical volume set might rotate and zoom and choose a specific angle to view some scan at, and then wishing a colleague doctor to see the exact same view of scan to get a different medical opinion about.</div><div><br></div><div>does anyone know if this can be done, and or provide a sample code implementation?</div><div><br></div><div>perhaps someone has actually done this - and might be willing to code such a vtk app for me. of course i would be willing to pay for this coding.</div><div><br></div><div>sincerely,</div><div><br></div><div>greg aiken</div></div> </div></body>
