JPD Posted August 21, 2006 Report Share Posted August 21, 2006 You'll find here a template which show how to do.The two first views have some more objects than necessary in order to show the movements.The view #4 show the result of the explanation.The view #5 show that we can do more with PTE.The view #6..#9 show an exemple with 8 objects with differents speed.Nota : with only one of these views and "repeat show" function, you will have this little show .Notice that there is absolutely no trouble on movement when the slide change, absolutely perfect on this test.

alrobin Posted August 21, 2006 Report Share Posted August 21, 2006 JP,That's brilliant! Nice smooth motion, too, without a gllitch. Also, your explanation "pte" version is very clever - it demonstrates very well how everything works. Vive le PTE! Quote Link to comment Share on other sites More sharing options...
JPD Posted August 21, 2006 Author Report Share Posted August 21, 2006 Vive le PTE!I agree with you, Al Quote Link to comment Share on other sites More sharing options...

The non-central point allows an eccentric motion in the arc with the planet passing closer on only one side of the arc. The same effect could be created with your model by moving the invisible anchor square in relation to the center of the "atom".In the Planet model, I needed the "electrons" (planets) to also spin on their own axis (with the exception of the Moon) so that's why the duplication of each planet with one being set to zero opacity. I didn't include yet another child relation to a "shadow" to simulate the true effect of the real shadow cast by the light from the Sun on each planet but that would have been easy to achieve.Imagine taking additional children anchored to the existing children in your simulation and the complexity of motion could be virtually endless subject to memory limitations. P2E is definitely a wonderful tool and could be advantageously used in the classroom for simulations in Physics demonstations.Best regards,Lin Quote Link to comment Share on other sites More sharing options...
thedom Posted August 22, 2006 Report Share Posted August 22, 2006 Jean-Pierre, Your show is absolutely remarkable ! You really are really talented with demo/tutorial. The way you put it is excellent and people just need to think to make the same effects.Do you give me the permission to host it on my site (the show and the tutorial) ? Thank you for your answer.

LumenLux Posted August 22, 2006 Report Share Posted August 22, 2006 This entire string of astronomical presentations is outstanding.I said in the first week of PTE V5 that a few good minds with a few PTE licenses could put whole animation studios out of business! Now I know who those "few good minds" could be. thanks guys Quote Link to comment Share on other sites More sharing options...
