  1. ^Its not exactly rocket science is it,lol.

    This is though

    where 3373298468e67b831345093e0ab4b98e.png is the momentum of the rocket at time t=0: 011dc47b9917cbf43e45350672358bad.png

    and 1dc83ef3d6e2e4ab7b969dd95c160d05.png is the momentum of the rocket and exhausted mass at time f4219d9cd080231fc2acb87d9f1574ff.png: 210c3265b53f2e755a5295497081e904.png

    and where, with respect to the observer: c3f97a4420c67227501e8aa037c1c616.png is the velocity of the rocket at time t=0 f26bff545b9f936b3b49d1ffb6e715e5.png is the velocity of the rocket at time f4219d9cd080231fc2acb87d9f1574ff.png0436d87c2b6c76e631e64dda8e9570c9.png is the velocity of the mass added to the exhaust (and lost by the rocket) during time 0460d7a69dc59138dcd9c85dbebebfe2.png859a25409f35f6fb73e4c87e08daecb4.png is the mass of the rocket at time t=0 79dd9720ffa5bbe026e23afc9ab4df3c.png is the mass of the rocket at time f4219d9cd080231fc2acb87d9f1574ff.png

    The velocity of the exhaust f5f6d11a1c9228b44abda6beeef79da7.png in the observer frame is related to the velocity of the exhaust in the rocket frame 5361d0af0de1c4e3771a8caef3639b7f.png by (since exhaust velocity is in the negative direction) c238ab3d76d78cc935bb995ccf47bf95.png

  2. I see there is plenty of confusion on the new rating system and I can see why,points and a rating sysytem just seems a bit dumb. Surely it should just be the rating system out of 5 stars with each voter adding up the score as he or she goes.

    ie. Voter one - I love image 1 and give it 4 stars

    Not so keen on image 2 and give it 1 star

    (No need to add who won as its obvious )

    Voter 2 - Image 1 is fantastic I also give it 4 stars

    I also quite like image 2 and give it 3 stars

    Score so far Image 1 - 8 stars

    Image 2 - 4 stars

    (and so on until one voter gives enough stars to take the tally on one of the images to 20 at which point that image is declared the winner and a new battle can start )

  3. ^Try not to think about the connecting line when using it and think of it more like the paint brush tool.

    lasoo.jpg

    Take the following example. You want to copy the red circle but not the blue one, the rectangle selection will be no good for this and lets pretend for this example that the eclipse selection doesn't exsist. With the lasoo selected place your cursor somewhere on the green line ( here just for a visual guide )and trace all around it,once completed it anything inside will be selected. You can then paste this into a new layer or project.

  4. Yep and it's a lot easier than you think.

    Find the two images you need on google and click on the "Full size image" then right click with the mouse and select "Copy image"

    Now start up PDN and select FILE>NEW this will open up a canvas at the correct size for the image you just copied from google then press CTRL+V to past it in

    For Jack sparrow I used this one then resized it by 50%

    Now do the same for this image of Mr Bean

    http://images3.wikia...oliday_ver5.jpg

    Now you can use LAYERS>ROTATE ZOOM to put the Mr Bean imag straight,then using the lasoo tool draw round his face something like this

    beanoutline.jpg

    Note I used the paintbrush so it shows up easier, you can also do this and then use the magic wand tool and click inside the outline. Whatever method you use then press CTRL+C to copy it.

    Now go to your Jack Sparrow image and add a new layer then press CTRL+V to past in the face of MR BEAN. Using one of the corner nubs resize it by holding down the SHIFT key and the left mouse button and position it over Jacks face it may help to make this layer slightly transparent so that you can line up the eyes correctly and you may wish to flip the layer horizontally to get a better fit LAYERS>FLIP HORIZONTAL

    Once you have the image where you want it you may need to erase small parts that are not needed on this example some of Mr Beans face went over the bandana so I erased them. You then need to feather Mr Beans face using EFFECTS>OBJECT>FEATHER at 10 and then repeat it again at 10 this helps the face blend in now you just need to match the colours up by using ADJUSTMENTS>HUE/SATURATION

    this is what I got with about 5mins work.

    Feather plug-in can be found here http://forums.getpai...?showtopic=2140

  5. The following pic should help.

    test.jpg

    Make sure you have the correct layer selected in the case above I wish to copy the blue rounded rectangle so I click on layer 3 in the layer window ( where the bottom orange arrow points )

    Then press CTRL+A ( this selects all ) CTRL+C ( this copies ) followed by CTRL+ALT+V ( this pastes into a new project as shown where the top arrow points, you can then select each project just by clicking on them )

  6. Off topic a bit but just re-read mine and welshy's tiff a few posts back and I wish to apologise. I was going through some stuff back then and I wasn't the easiest person to get along with and think I probably should of kept off the forums at that time. So if you are reading this welshblue sorry ;)
