When I watch the right handed one hand backhand…at some point when viewing it, it seems to me that I am viewing a left hand backhand from a rear view. Anyone else get that impression? It's an odd sensation.

I get it when I watch the right handed forehand. Suddenly it's left handed. Interesting how the other guys talk over this.

That is so cool…I actually looked for it but didn't see it initially on the forehand. Suddenly there it was. Sometimes I seem to miss it and see it from the "correct perspective". So how does one go about explaining that little visual anomaly. Brian Gordon?

[John Yandell]

So you guys caught that right? Before I edited it to merge the three it was really trippy. Sometimes you see it one way and some times the other.

Brian tried to explain it to me but apparently it went right over my head something about three dimensional something... I see if he can drop it and educate us.

I like it because it's evocative and mesmerizing.

I have to say this is all a bit strange. I thought you two were going a bit peculiar on me....then I saw it too...on the backhand....then on the forehand. I keep looking at the two-handed guy assuming it must happen a some stage or other to him too. It's all a bit mesmerising...

Wireframe Depictions

Hi All -

The programs that generate the wireframe representations were coded many years ago. At that time I was using film 3D reconstruction so did not have the information to track head rotations - so... the head simply faces the same direction as the upper third of the torso and NOT its actual orientation. From a purely mechanical perspective it is not that important to me so I have not gotten around to changing it even though I now have that information - lazy.

The forehand and bh1 are the same male player - a lefty with the view shown from behind for both strokes. The bh2 is a girl righty seen from a perfect side view of the hitting side. Though many have tried, it is impossible to know if one is viewing a righty from in front or a lefty from behind unless that information is given - the wires do not allow a perspective of the dimension into and out of the screen. It is a bit of a mind blower .

Mind is blown. I'm not smart enough to figure it out.
on another note, I'm 8 minutes away from where Brian works. I'm long overdue for a visit and vice versa.

It's pretty cool. But yeah the head looks like it is moving early. Also it might be better with the real video included and also the ability to play and pause through them.

Screen Saver...

It would make a great screen saver with a view of the forehand and the backhand at the same time…maybe back to back or would that be face to face? Get the picture?

Hi Kyle - shoot me an email. I'd enjoy stopping in to visit your facility - I've heard it is quite nice.

Now the figure appears: but does not move.... (IPad)

[John Yandell]

Well that's something...it took it a while to move on my iphone...but even if it doesn't it still looks pretty good...will keep on it...

[gzhpcu]

Works fine on iPad now...

[stotty]

Works fine on my Android phone...
