  Coordonates. Axis orientation

  Posted by Nicolas Guionnet on February 26, 2019 at 9:22 pm

  Hi,

  This question is probably very basic. I am a newbie.

  I have used expression to create a mathematical animation involving coordinates.
  I discovered that the y axis was downward oriented. Off course, it can be corrected in the code, but as it is spread in various fragments, it is not the most elegant way to do this.

  So, is there an option somewhere to adopt the classical math orientation ? … must I use some horizontal reflection effect ?

  Thank you !
  Nicolas

  I think the best you could do would be to flip it at the end of your expression, like:

  // do your x calculation

  // do your y calculation as if + is up

  [x,-y]

  I wouldn’t recommend doing that though–you do get used to it being the way it is.
