Scaling

Quartz Composer Visualizer scaling problem

apple pi's picture

Hello everyone, I have this composition that I want to span through 2 monitors. There are lots of animated image buttons, that are in real size setting in the billboard patch. But when I use the QUARTZ COMPOSER VISUALIZER , it scales up every image on screen, when it stretches to both monitors. What can I do to avoid this unwanted scaling? Thanks in advance

here is a javascript interpolator or mapping function. it doesn't have its own time base as this is just to scale numbers. so it will not generate but it does map. why do you need this if apple interpolator works fine. maybe your inquisitive like i am as i seem to do a lot of interpolating plus the curve feature is exposed so you can interpolate a curve overtime. does that make since interpolate your interpolator curve ?

well maybe you want ease out or in a little longer for a specific period of time or more or less than you can draw a cubic or quadratic curve etc... if you set the curve to zero it is linear. so ironically i'm using an interpolator to generate a range of 0-127 integers so i can map that range down to a -1 to 1 float range with some simple javascript logic based on powers of 10.

im thinking i will do a javascript smooth later with its own time base so it will smooth and generate numbers ? maybe a hermite interpolator or something is not in QC. paul bourke has lots of wonderful interpolation examples on his site is this stuff interests you.
