With the help of BgDM, GreyBeard, and numerous other people on Elysiun who have been so kind as to answer my constant questions on this subject while maintaining their composure. I would like to post a mini-HOWTO on the subject of creating a scene with a camera which continuously circles the subject.
Knowledge of how to place the cursor, create objects, and use constraints is assumed.
Step One – Create a subject model
1.1 Creating the subject of your animation is outside the scope of this HOWTO.
Step Two – Create Two Paths
2.1 Determine the radius of the circle and the frame count you wish the camera to follow around the subject.2.2 Create a Bezier Circle centered on your subject and with a radius of the camera position.2.3 Create another Bezier Circle centered on your subject and with a radius half of the camera path.2.4 Place an empty on the inner path. Add a Follow Path constraint to the empty to follow the inner path.2.5 Place a camera on the outer path. Add a Follow Path constraint to the camera to follow the outer path and a Track To constraint that focuses on the Empty previously added.
Step Three – Create New IPOs
3.1 Switch to an IPO Editor view in another window. Select the inner circle.3.2 Ctrl-LMB click to create a point at 0,0 on the curve at the starting frame. Likewise, ctrl-LMB and create a point at the middle frame of your animation. Ctrl-LMB click to create a point at 1.0, 0 on the curve at the ending frame of the camera circle.3.3 Press TAB to switch back to Object mode and select Curve->Interpolation Mode->Linear to change the curve.3.4 With the line selected, Extend the curve by choosing Curve->Extend->Cyclic
You have created two paths surrounding your character and placed an empty and a camera on those paths. The camera is directed towards the empty which is in front of your subject. Because you chose to Extend the IPO curve in a Cyclic manner, the camera and empty will continuously circle your subject.
The scene can be viewed or saved to your hard drive. This mini-HOWTO will also be expanded into a true instructional document.
Many, many thanks go to the community here at Elysiun! I cannot say enough about the helpful instruction here that is only waiting to be tapped.
