Delta can manage up to 32 meshes (16 prior to version 2.6.48). Since in mesh mode, media can be associated with specific eyepoints, and eyepoints can be associated with specific meshes, we can have simultaneous media on a timeline, to be projected onto separate objects using their own meshes. Here we have two images, and have assigned them to different eyepoints by disabling all others:
Here we have two meshes, for a tube and a cube, set up in DeltaGUI, with different eyepoints assigned to them:
Here in Playback we have media 1, associated with eyepoint 1,which is associated with mesh 1 (the cube), and media 2, associated with eyepoint 2, which is associated with mesh 2 (the tube):
Note that the media eyepoints are using textured coordinates.
