Are these straight plane lines?

[shortgamer]

Here's some food for thought.

Is it really garbage, or is this a valid way to analyze a golf swing for "correctness" through 2 dimensional video analysis, due to parallax?

What I hear you saying is that if you took a Ben Hogan, Tiger Woods, David Toms, or Mark O'meara swing sequence in 2-D, where the shaft is pointing outside of the target line, and, if you could somehow superimpose that same exact swing in a 3-D analyzer, or somehow magically put a laser pointer on the butt end of their club, that these players would be proven to really be tracing a straight plane line.

Well, if that's the case, and video is your only tool to analyze your golf swing, then you have to concede that the parallel planes theory is valid at least when looking at 2-D swing sequence.

I see what you're saying, it's like if they're all above plane at a certain spot they're actually on plane in the real world but I think the problem is that for that to work you have to have every single person in the exact same spot with the exact same ball position aligned the exact same way. Any variables and it's all thrown out the window.

I'm with mjstrong, I don't get what you're saying VJ...

a little off...

Maybe I need to re-read Haney and see if I'm getting his idea right, but from the sequences of Tiger that I've looked, here's what I see: Tiger seems to trace this idea of congruent angles very well in his backswing and at the top. On the way down, however, he gets the butt of that club pointed at the base of his intended plane at impact. He's "on plane" on the downswing.

I'd upload this sequence that I got off of another forum, and then added a few things to...but I don't know how. Do I need somebody to host the pics?

photobucket will host your pics and give you a img code which this site reads.

WHAT???????????

Vic......

It matters a LOT!

If you TRY to make your shaft do something in 3-D world (where we all live) that only looks "as if" in 2-D world...you are SCREWED.

Case in point: [NO NAMES PLEASE]

I once saw a world famous player, at a Major, on the range, shown pics of this PARALLEL PLANE CRAP on a 2-D sheet of paper by his teacher. The world famous player, known throughout golf for hitting it on the sweetspot almost everytime, trying to do "as if"....

PARALLAX!!!

not only is it parallax, sometime it REALLY isn't pointing at the plane line!
