Hi. I'm working on building a scrolling display (with images as input) where the pixels are cubes. The finished version will have the cubes scale in z level based on music.

The attached patch is as far as I've come now. You load an image, and the cube grid will rearrange itself.

To run you need the pdmtl abstractions installed. Just unzip the pdmtl.zip somewhere.

Also, to use the pdmtl abstractions you need to first add "moocow" to pd's path and then the path to the pdmtl directory.
/usr/lib/pd/extra/moocow
/path to unpacked pdmtl

My current problem is that of loading a list of images. In the help for gems.images there's an example of how to use files, but I can't get it to work. Any ideas?

This has probably been dealt with a thousand times (and I guess there's also recipies for it). I'm working on a patch using gem which will react to music. What do you use to record both video and audio into avi files?

Hello all.

I want to load an image and them retrieve the pixel data (colour) of the individual pixels using coordinates. I've tried pix_data and that doesn't seem helpful. I get some values, but they are not what they're supposed to be. Is there any other object I can use to retrieve pixel data?

To clarify: I don't want to display the image as it is, I want to build sort of a "LED"-scroller of cubes and use images as input (much easier if I want to animate I guess...).

Any suggestions?

I've posted a new thread with my patch as it is now.

Of course I forgot to write the important stuff, such as OS...

I'm using Linux and the jack sound server.

I got it working now. I'll post it as soon as it is finished.

Does Reason have support for jack?

Oooh, this looks nice. I'll have to look at it closer tomorrow.

I sort of got it working, but there was something probably wrong with the video files I provided. pd ended up using 99% cpu. I'll have to look into it when I'm not as tired... I'll probably also ask dozens of questions.

That's really nice.

I'm just starting out with pd and gem (I've hoarded lots of links to read "when I have the time"...) and only found this forum yesterday. Where should I start learning? Can you repost the patch somewhere?
