On a related note, I've been hoping to find a way to add movable camera focus blur to 3-d primitives. Is there an easy way to do this with Gem?

See the example on this page: http://www.opengl.org/resources/code/samples/glut_examples/advanced/advanced...

We want to process a blur effect on a specific area on video. To be clearer, we want to blur faces... To find faces, we use [pix_opencv_haarcascade ]...

1. blur the whole picture

2. use the output of your detector to make a mask

3. use the mask to "cut holes" through the normal picture, using the

blurred picture. if you were to only do [pix_texture] on the final result, you can do [pix_texture] on both the normal and the fully blurred image and combine them using two separate [rectangle], an [alpha], and a [pix_alpha].

even though it may waste a lot of blurred pixels, at least you can do it on all sorts of nonrectangle shapes.

je suis pass? tr?s proche d'utiliser ?a hier, mais avec une autre sorte de d?tection compl?tement diff?rente, en particulier parce qu'on voulait que la zone floue soit nonrectangulaire et graduelle (un "gradient" d'alpha, dans l'jargon).
