thx oilyrag, your explanation at least give a reasonable answer why the putt didnt drop. Think I (at least) partially get the point, but I want u 2 ask some additional explanation.
As far as I get the point u're making, is that the blue arrow above indicates where the ball is touching the ground (in that case it still should drop i think, cause its withinin the line of the cupedge). When the blue arrow is a representation of the backpart of the ball, than its totally clear 2 me that the ball shouldn't drop. Everyting between those 2 representations of the blueline are vague and there is a possibility 2 drop or stay.
2 make it even more complicated, when comparing it 2 an eclips (the putting line in 2d), than u cant say anything about it at al, so every discussion about it is totally useless in that case....true? :)
Finally, perhaps u can help me with another example which I think is slightly different in that the putt is almost straight (so the representation in this case should be rather accurate) and there is definetly a little drop in hight at the end of the putt. Or could this be an optical illusion 2 (I'm thinking of a 3d sharp bend represented as a drop in 2d)?:
