Cam into ofPixels

beginners
#1

what i’m trying to do is to is:

  • get pixels of the webcam into units of (10 x 10 px for instance)
  • put the 10 x 10 blocks into a vector i think
  • rearrange those blocks randomly and draw it in a grid.

anybody any idea how to do this

see example below:

You could do this dynamically using drawSubsection();

ofImage_::drawSubsection(float x, float y, float w, float h, float sx, float sy);

This way you don’t need to copy pixels manually, just draw the bits you want where you want.

thanks for your reply, does drawSubsection work with a webcam livefeed?

yes you can usevideoGrabber.getTexture().drawSubsection(float x, float y, float w, float h, float sx, float sy);
