Shapes actor and sizes



  • I was about to submit a bug report but wanted to try understand if there is some other logic here.

    Using the shapes actor you can adjust the number of sides. If I set it to the max (to make an ellipse for example) and set the size to a width of 40 and height of 20 I would have expected that the height and width of the elipse would be the same as the height and width of a rectangle with the same settings. 

    However it seems like this is programmed so that the resulting shape can contain a rectangle of the width and height settings. Although I could see some cases where this is useful, I would think it more logical to have the actual width and actual height of the resulting shape be what I put in. I am often working against isadoras use of percentages to define coordinates (although I have found it saved me from work on a few occasions so I get it). If I want to define a circle with a precise location and size in pixels, even when using a calculator to work this out from the default processing resolution, it becomes very difficult with the current system.

    Am I alone in thinking that the height and width of a shape should be consistent no matter how many faces it has? Is it meant to be like this or is it a bug. I would guess that if it is made consistent then old patches would need adjusting as the shapes would come out different sizes.

    You can change the behavior using the 'inside' input.
    To have a Rect and Oval paired up the way you outline, the Non Rect, needs to be set to 'inside' = On

    With the Inside set to On, the shapes correlate with width and height a little more closely, but its still not accurate until you get to 24 facets or more. Please see the attached movie.

    edit: i don't think the file attached, so i uploaded it to youtube: 



  • @dusx cool, I did not even try that- of course mark thought of almost everything.
