Hey guys! sorry but i'm new in jitter, and i don't understand at all what jit.matrix does. I know how to use it, i know that is similar to de buffer~ object in msp, but i don't know what can i do with it. Just that, cuz i'm already prossecing visuals and videos with quicktime, but i don't know what can i do with matrix. So i know how to use it but i don't know what can i do with it. Thanks much!

a shortly answer will be great.

Easiest way to explain is with an example:

jit.qt.movie takes a QuickTime movie, inserts it into a matrix, and outputs that matrix.

jit.matrix can be thought of as the generic, empty matrix that all jitter objects use. Therefore you can use it for just about anything you need a matrix for. And of course you can load and use those matrices for a variety of things (like OpenGL geometry).

Is there a short answer for such a question? :-)

A matrix is an array of values that is used to represent behaviors of the jitter objects. If you are working with a movie, the color information would be stored on a matrix representing the combination of 4 values per pixel: ARGB(alpha, red, green and blue).

If you are working with openGL matrices represent things like the position of objects, transformations (rotations, scaling, etc), normals and camera positions. If your interest is to work with 3D objects I strongly recommend you to get a nice openGL book and read about all the processes behind the 3D viewporting.

About what to do with them, I assume that you are asking what the limitations of the system are in terms of implementation, right? I recommend you to read the tutorials and to get the super nice jitter recipes (google it on the forum)

Thanks much guys, i'll read something about openGL then. But i think i solved my doubt.

Plis help! with jit.matrix
