Max/JItter + Syphon = problems –> Blur between different shades in matrix

August 7, 2012 | 9:50 am

Hi All,

I'm currently working on a max-patch, sending a 2d jitter matrix to MadMapper using Syphon. When I have one matrix, containing 3 different colors, I send it to MadMapper using syphon, but between my different colors, Syphon (??) somehow make a blur -> even though my matrix is a sharp edge / non-fade between the colors.

Is it a problem when rendering a 2d matrix with OpenGL, or what am I doing wrong?

Noone else had the same problem? I really can’t seem to figure this guy out.. hmm

You are sending out a 40×10 texture. Whereas a Jitter matrix is displayed without interpolation by default, OpenGL textures use linear filtering (interpolation) by default. Your best bet will be to upscale your matrix to a larger texture before passing to Syphon, unless it’s possible to turn off linear filtering in your destination application.
