drawingFelt Tip (Composition by gtoledo3)
This composition shows a way of creating a stylized line drawing patch that can create drawings that look like organic drawings done with a marker. It requires v002 Dilate and GL Tools. Draw QCMesh (Composition by gtoledo3)
This composition allows for drawing of QCMesh with normals that work with the lighting environment, mesh that works with shadows, and also that doesn't cause any weird evaluation side effects (eg., other stuff in the composition ceasing to evaluate). It features non contiguous drawing, all stock patches, ability to change color at any time (eg., typical "paint" feature), and line and point sprite modes (stock). Notes: -Point Sprites have an aberration rendering with shadows where the shadow engine seems to think they are "larger" than they really are. This is an Apple bug, I believe, can't do anything about it. -I've "deprecated" the Mesh filters (this composition is somewhat related to the "wiggle draw" I posted). When you "draw" while a filter is engaged, normals can break. This makes no sense given the patch ordering, and again, I believe this is an Apple/ QC mesh bug that I can't particularly do anything about. -"Double clicking" to clear reduces queue count to 1 instead of 0, but this isn't really perceivable in visual result. This is to suppress a QCMesh log error when mesh creator is connected to a QCMesh render and while input ports are attached, but no structure is being fed (which I believe shouldn't happen to begin with, but log errors annoy me, so I did this to suppress it even though I believe it to be questionable. I would rather leave this value at 0 in a perfect world). Stock Patch Linemaker_GT (Composition by gtoledo3)
I'm posting this to show how to do "line structure" style drawing with all stock patches. This has some provisions for color and thickness as well, so you can have lines of differing color and weight on screen at the same time. particle tools questions Hey All Thanks for your wonderful site. Is it possible to make particles stick around longer than their default life span of 1e+10? Id like to layer particles like paint. Thank you!
ManyCam plugin patches for QC I've just discovered that upon installation, ManyCam also installs some QC tools: ManyCam Webcam.qtz appears in Library/Compositions and in the QC Patch Library. Additionally, a seperate ManyCamPlugin patch appears in the Patch Library. I hadn't noticed them before and I'm suspecting they may have required an initial usage circumstance to occur before appearing. After I first messed with the .qtz in Library/Compositions is when I started seeing them. The .qtz also then appeared as an effect in CamTwist, interestingly. Usefulness will vary by individual, but the broadest description is that the plugin seems to be able to both bring ManyCam into Quartz Composer as well as to bring QC into ManyCam. Sounds peculiar I know, but that's what I'm seeing. What's it good for? hmmmm. ManyCam has a simple drawing tool, for one. It can also do screen captures with options for capture sizes and for cursor-following. It has an abundance of effects, although many of them are somewhat common, imho. ManyCam also has a fairly decent face tracking tool (discussed earlier and briefly elsewhere in these forums) which is image-graphics assignable, the caveat being that those graphics need to be specifically hosted in ManyCam's face accessories function in order to be accessed. Anyway, I'm going to explore it. Both the plugin and the .qtz appear to be set up as image filters so I'll insert them around in my compositions and report further if anything visually interesting develops.
