Re: Particle Patch Problem

Title: Re: Particle Patch Problem
Hi John,

Thank you very much for the explanation and your "image normalizer" macro. I doubt I would have figured that solution out by myself. :-)

I have updated my version to 1.2 and given you credit in the file’s ReadMe at:

Sincerely,

Don

Don,

It's not a bug. 

The particle system draws a series of square Gl quads, and it will fit the given texture to those quads.   If that texture's aspect ratio isn't square, it will get stretched.  I have an "image normalizer" macro that deals with this, in this composition:

What the normalizer does, is draw the given image over an infinite field of the given color, and then crop it to a square whose size is the greater dimension of the image.

I've dropped it into your composition:



HTH,
