10.5Mac OS X 10.5 (Leopard) Lighting with Read Pixels (Composition by gtoledo3)
This is a composition that takes the depth buffer from a QC scene, using the GL Read Pixels from GL Tools, and the color buffer, and composites them using a GLSL normal map shader (cwright's Normal Map Demo I). A normal map is derived from the depth image provided by Read Pixels, to create the lighting effect, using a custom CI patch. One of the cool byproducts (to me at least), of doing this, is that it shows the "flat lighting"/non smoothed version of the QC scene when you read the actual Depth and convert to normals. It used to be possible to read the color buffer using GL Tools Read Pixels; this broke in SL. So, this also shows how reading the depth buffer can still work, and how one can still get color by employing RII. It does a pretty good job of painting pixels that should be occluded darkly. It's a sort of fragile setup, and it's possible to break it by changing it (eg. adding extra processing at different points, flipping various non-published params, layers, etc.). Tentacles - The Return! (Composition by gtoledo3)
I did a little mashup of my upload from yesterday. I have it creating a normal map on the fly, making it's own lighting using greyscale procedural feedback trails/particles, doing a low-rent volumetric light thing, and working with multitouch. You'll need kineme multitouch patch, and the normalmap_gt plugin from my page (georgetoledo.com). It's semi 10.5 compatible. One of the particle systems/iterator combo's uses smooths inside... that won't work the same in 10.5, but the rest of it generally will. Tentacles (Composition by gtoledo3)
This is a QC interactive graphics composition that renders tentacle like graphics with multitouch. This uses the kineme multitouch patch. One thing that's probably kind of generally helpful(?) in this composition, aside from the multitouch or graphics stuff, is that it coaxes a particle system to render something on the second iteration, when two fingers are down (it seems like there's a QC bug that prevents that from working as expected). Mouse Trap (Composition by dust)
the plugin is called mouse mover it shows up your library as mouse trap. input_x and input_y need to be in pixels. left button down and up should be pulsed in etc.. use this plugin at your own risk. CI Normal Map_gtII (Composition by gtoledo3)
This is a companion to the other normal map filter, that samples from more pixels than CINormalMap_gt to make it's normal map from heightfield. Included is another composition that makes a normal map on the fly using this filter. |
