Re: help with rotation



hmm.
not sure what you mean, but..

1. Tried embedding a sprite renderer within a Render in Image patch. It only displays if you turn off depth testing, but then you get those classic "Director-style" trails, which I don't don't need here.

just add a clear patch in the Render In Image


2. Tried using Affine transform for just a Z axis rotation test, but the video dimensions stretch as you rotate, and the aspect ratio is lost. Moreover, the rendered area seems to expand vertically but not horizontally. What am I missing with these types of transformations?

affine-transform changes the image/dimensions (what's in a name..)
in order to maintain the right aspect you need to addopt the renderer accordingly.
this is one way of doing that:

There are some examples on Quartcompositions.com, but they all seem to suffer from the aspect ratio loss issue. Any suggestions?

maybe what you're looking for is the '3D Transformation' patch?
and are you sure you're not confusing 'perspective distortion' and 'aspect ration loss' ?


otherwise, make sure that your 'some other processing' outputs the expected dimensions
