Neil Woodhouse Posted August 18, 2008 Share Posted August 18, 2008 Greetings, One for the Lords of animation A bit of a head scratcher. I've just been asked to produce a 3D logo animation, which at first i thought was going to be one of those 'I'll let you have it back Tuesday Morning' jobs. However ( laughs ) it's got me thinking. Basically the company wants to run a camera constrined to an animation track within a Torus Knot. Now the knot is easy, but how the devil do i put an path in there that runs centrally in space thru' it? Scratch, Scratch. Neil Link to comment Share on other sites More sharing options...
shaneis Posted August 18, 2008 Share Posted August 18, 2008 Hmm, * generate the torus, * extract the knot's curve from the torus, * use the curve to extrude the knot's surface, * use the curve as a motion path. Link to comment Share on other sites More sharing options...
BrianKitts Posted August 18, 2008 Share Posted August 18, 2008 (edited) my route would be this.... (not sure if this is what shane meant, but it's a bit more descriptive) 1. create to torus. 2. convert to editable poly 3. grab one segment running the direction of the torus 4. select "loop" 5. select "create shape from selection" 6. slightly shrink the new shape using uniform scale to pull it into the center of the knot. 7. create your camera, and attach it to the new shape as a path constraint.

SandmanNinja Posted August 18, 2008 Share Posted August 18, 2008 Yup. I concur. Link to comment Share on other sites More sharing options...
Claudio Branch Posted August 18, 2008 Share Posted August 18, 2008 Brian's approach will get you there, but if you change the Cross Section Radius spinner value to 0, you will basically have your spline path now going through the center of the torus section. Collapse to EP, select an Edge and use Loop, then use Create Shape from Selection. Pretty much the same thang... Link to comment Share on other sites More sharing options...
BrianKitts Posted August 18, 2008 Share Posted August 18, 2008 if you change the Cross Section Radius spinner value to 0, you will basically have your spline path now going through the center of the torus section. nice.... I was trying to think of an exact way to center it and came up empty, well done. Link to comment Share on other sites More sharing options...
Neil Woodhouse Posted August 19, 2008 Author Share Posted August 19, 2008 Thanx Guys, I've followed all the pointers and it works an absolute treat. Cheers, Neil Link to comment Share on other sites More sharing options...
Neil Woodhouse Posted August 19, 2008 Author Share Posted August 19, 2008 Or i thought i had. Where is the cross section radius spinner located? Can't find it! Neil Link to comment Share on other sites More sharing options...
Claudio Branch Posted August 19, 2008 Share Posted August 19, 2008 Just look under the torus knots' parameters. The first series controls the Base Curve and the second series controls the Cross Section. Link to comment Share on other sites More sharing options...
BrianKitts Posted August 19, 2008 Share Posted August 19, 2008 in the parameters in the cross section options right after base curve options.... Link to comment Share on other sites More sharing options...
Neil Woodhouse Posted August 20, 2008 Author Share Posted August 20, 2008 Thanks Guys, Got it now. I'd converted the Torus to a poly, which is why i wasn't seeing it. Started with a new knot made a copy of it, reduced the copy cross section and it works. Thanks again lads. Regards Neil Link to comment Share on other sites More sharing options...
