Hi, I really need help with this one..... Is is possible to save some live 3D images (from a 3D geological model) into a video file (.avi)? I tried using Camtasia to capture the model but it just displays the info in mono mode. Thanks a lot! Sebastian | ||

No. It is impossible. I expect you use OpenGl stereoscopy + profesional modelling application. In such situation the capturing saves only left eye view. It will need source code modification of your application ... | ||

The only way is if you can put the object in horizontal or circular motion parallel to your view, and can screen capture in real time, like with Camtasia (as you said you did), or one frame at a time, by moving the object in very small increments and capturing each movement. I don't think you can use Camtasia with OpenGL, so you must have used some other kind of object viewer? I think Camtasia requires no video overlay. (I can't remember :-) In scenes involving more than one object, if you use horizontal movement, be sure to move the object and not the camera centered on the object, or you will get image distortions. If you use a circular object motion, be sure to isolate that object, because an other imagery will not appear correctly. To make a 3D movie from this, delay one eye's view by one frame (or field), depending on the direction of movement. You can do it with freeware like VirtualDub or with some commercial softwares like Adobe After Effects. You end up discarding the first frame of one side and the last frame of the other. You can convert these to any other 3D format with software like VirtualDub, or you can use one of the freeware video players. P. K.

Obviously, you will be limited to horizontal movement, this way. You may or may not find that useful, depending on your desires. Before giving up, search for a program that might be able to display your object stereoscopically. You might be able to screen capture that in real time. I think I remember doing that. I can't remember the name of the program, but I don't think it was freeware. I'm sure somebody in this group knows the program I'm talking about. All you have to do is be able to open your object file type. There also might be an object file type conversion program, somewhere, so never give up "until the fat lady sings". You won't be able to use video overlay for screen capture, so that could be a problem, because you will probably lose all of your video card capabilities. That might limit you. Many times, there _is_ a way to do it, one way or another. Not always, but many times :-) PKK | ||

And, I'm talking about a left perspective and a right perspective. You really need a program that can separate your object out to a dual view, in order to build a good 3D movie. Use something that you can import into Adobe After Effects, and you can make Spy Kids 4 - 3D ;-) If you could screen capture interlaced 3D or anaglyph, you could make a movie file in those formats, but dual views are always best. Hope this all makes sense. There are options, but getting your object file type into other programs that can do what you want is the trick. It might not be possible with your particular object file. :-) PKK |
