Hello All! I have a question about GEM. What is that question you ask? Well here it is:
I want to perform an iterative process to a texture in GEM. Is there a delwrite~ type object for GEM, something that would hold a snapshot of a texture and emit copies of what ever texture was last recieved on bangs?
Exampla Gratus (I hope my ad-hoc web mail interface doesnt screw up my ascii diagram below...):
[pix_image Demo01.jpg] | [pix_texture] | |--------------| | | | [metro 100] | | | | [pix_hold] | | | [my process] | | \------- | [square 3]
Thanks for the help! You guys and girls are great! -thewade
Hello,
[pix_delay] is a good starting point for holding frames.

a) are you sure you are talking about textures - as opposed to pixel-images ? a pixel-image (or just image,...) is an image-data representation in main-memory. this is, what almost all [pix_-objects work on. a texture is the image-data uploaded to the openGL-server (in most cases: your gfx-card); there are very view operations you can do on textures, as there is no direct access to that data any more (well, modern gfx-cards would support pixel-fx that are executed on the GPU, but Gem does not yet)
b) supposed you are talking about images: the object that does exactly what you are describing is [pix_buf], a buffer for images. (can either be banged or emit a copy of the image each render-cycle automatically (auto 1).
c) if you want to do feedbacks, you should also have a look at [pix_buffer] (something completely different!), [pix_buffer_read] and [pix_buffer_write]

I'm looking for someone who can teach a PD course in Brighton, UK. Hopefully an evening course over a whole year, but I would be interested in running a more intensive short course. Would be introduction to PD through to reasonably complex stuff, hopefully with video as well. Anyone interested, please let me know. Thanks, Ivan
