I'd be really REALLY grateful if someone could tell me where I'm going wrong with this incredibly simple QTZ. I'm trying to do a really simple mirror effect, where the input image is mirrored around its centre on the X-axis.
The thing is, when I connect the result to a Billboard, it looks OK, however, when I connect it to a GLSL Shader patch with a GLSLGrid patch inside, the image is offset on the X-axis. This is not the case with an image piped directly into the GLSL Shader patch, so it's clearly something to do with the the Reflect CIFilter. I also notice that the preview image I get when I hover the mouse over the outport of the CIFilter also exhibits this offsetting. Despite the best efforts of several people on the list, I'm still having problems understanding DoDs and ROIs, and how they specifically relate to the kind of very simple Kernels I'm writing. I've added some extra JavaScript code to the JavaScript portion of the CIFilter, following earlier advice from Kevin Quennesson, but I have no idea if this code is really necessary for this particular filter kernel- removing it seems to make no difference. I've attached a copy of the QTZ in question, and would be very grateful if someone could spare some time to have a look at it. Thanks a lot in advance, a|x http://machinesdontcare.wordpress.com _______________________________________________ Do not post admin requests to the list. They will be ignored.
