Actually, I realized I left out a bit of the equation after sending the initial emal... Also, thanks Vade- at least I'm not the only one that this is a bit fuzzy with!I also want to understand what is happening in the QC app when you go into the advanced options and control these three settings:-highResolutionCoreImage -lowResolutionCoreImage -uncorrectedCoreImageI understand if there simply isn't documentation on this, but I'm thinking that maybe there is, and I'm overlooking, or just not putting the pieces together correctly. I'm wondering how they work hand in hand with the Native Core Image setting, and if enabling/ disabling any of these would run counter to the actual renderer settings, or if enabling highResolutionCoreImage on consumer patch, like a sprite, would be equivalent to using a billboard with Native Core Image Rendering enabled. (It seems not, in my testing, which leaves me scratching my head even more).I also wonder how the "rendering quality" control works with these factors, but this is less of an issue at the moment than getting to the bottom of this aspect of CI Function within Quartz Composer.Thanks! -George Toledo On Mon, May 18, 2009 at 6:26 PM, vade <[email protected]> wrote:I too would love some more in depth explanation to what this does, and how color correction in QC works. Its a bit of a mystery to me as well. Good call George :)On May 18, 2009, at 4:16 PM, George Toledo wrote:When Native Core Image Rendering is enabled it indicates that the filters render directly to the destination context. I understand this, but I don't understand what it is rendering to if it's not rendering to the destination context. I am basically seeking an explanation of "what exactly is happening to impact performance to this extent".I've looked through the Core Image Filter reference pages, and all of the applicable Quartz Composer pages, and am wondering if anyone has a link to the definitive page on this, because I think I may be overlooking something.It seems that it is changing the way that color correction happens? It seems that enabling Native CI Rendering is making it do more color correction checks at each step, or one giant color correction step before the renderer?Thank you, this is very basic, but it's never been completely clear to me what is going on under the hood with this.Best regards, George Toledo _______________________________________________ Do not post admin requests to the list.
