Creating an immersive projection in QC

monobrau's picture


I'm wondering if anyone has experience or advice on the following problem I'm trying to solve.

We're tying to create an immersive projection, based on two walls at a 90 degree angle and a floor plane. Something like CAVE or the ps3 commercial

Right now I came quite far using three manual set 1024's perspectivematrix patches with the same 3d scenes from different angles. It is still not perfect, and the textures won't align seamless in most cases.

I've attached a sample patch with my current progress. You'll need Kineme's Datatools, filetools, GLTools, Vade's Syphon, and 1024 perspectivematrix plugin's.

I tried different approaces experimenting with the FOV, camera, matrix transform and lookat patches and mesh warping in madmapper without better results than this current perspectivematrix approach.

Ideally I think it's best to be able to generate a cube map of a 3d scene in QC, but I can't find any elaborate resources on how that's done.

To sum it up:
Is it possible to generate a cube map in QC?
Might there be a different approach that I haven't though off?
Do you have some leads to more info on this topic?


Midi control over Counter patch

I'm trying to control pixel accumulator values via midi-controller (Akai MPK Mini or Novation Nocturn). I'm using "Counter" for increasing and decreasing the signal, at the moment it can only be done by using Mac keyboard's arrow buttons (left - and right +). Does anyone know how to map those commands to Midi-controllers faders or rotation knobs? I hope someone understands my question :) Thanks in advance!

Mappit v1.2

Just wanted to share the newest version of my video mapping software that was built in Quartz Composer. Mappit, as I call it, aims to be an entry level program useful for mapping out surfaces, building, shapes, etc with a projector. I consider it a very handy tool and I am sure someone will be able to make use of it.

In this version there are several upgrades including the interface, and the ways in which Mapp's are assembled and moved. This is of course free, and couldn't have been without the great help from this community.


Mappit v1.1

I introduce Mappit v1.1 Mappit is a easy, free, simple to use Video Mapping program that can display any picture or video, on up to 9 customizable surfaces.

I spruced up the original Mappit and made a few changes and now it is ready to be used.

I simplified the layout, added more video formats, better media playlists, more mapps, live video feed, and simplified install.

So check it out, and give Mappit 1.1 a try

This composition illustrates how to construct triangles in QC using only stock patches, and also how to UV map them, so that they are successfully textured.
