Hi, I'm giving it a lot of laps and it's driving me crazy, I want to do the same but with the hands of the kinect, I don't know anything about programming and touchdesigner I'm learning something little by little, but I have managed to create the points in the hands with the UV coordinates creating another GLSL color like the original one and sending the coordinates of the other hand and the uRadius and uAspectRatio, my question is: can I add the other hand in the same GLSL color without creating another GLSL? I have been testing creating another uniform vec5 uPoint or uPoint1; but it doesn't come out, I don't know how to do it, can you help me please? Thanks a lot

Amazing! Thank you so much! I just made the move from Processing to TD and was looking exactly for this specific Joe Stam paper's implementation. Although it's all there in the video, is there anywhere we can find the .toe for this project?

I'm experiencing a fatal error with the shader splat.frag text file. I'm able to open it and edit it but once I save it in a new location (I liked the idea of having a separate folder for shaders like you), I'm not longer able to edit the file. Once I've moved it and relinked it inside the GLSL Pixel node, I'm not longer able to open it by clicking the Edit button. It crashes the program.

@bentheremedia3011 Жыл бұрын

Okay I think I figured it out. The error was that the file couldn't be located for 'Sync to File.' I disabled Sync to File, clicked Edit, saved the file into a new location, selected the file by clicking the plus sign, and then re-enabled Sync to File. It seems that I may have gone out of order by clicking sync before selecting it with the plus sign.

Hey! On both the color and the velocity GLSLs I get the error "'vuV' . undeclared identifier" and 1 compilation error, but I'm pretty sure there are none. However, the color GLSL works fine while the velocity one doesn't.

@jaceweyant2678 7 ай бұрын

might just be a case sensitivity thing. try vUV instead of vuV

Edit: tried doing it with a motion detection thingy ( kzfaq.info/get/bejne/oNtkeZSUrM6pZoU.html ) And my camera wouldnt work :D :D Saving the project and restarting TD resolved the issue for me, and Mouse In works now as well. On some mac machines, it doesn't, so you might get a neat workaround with your FaceTime camera and aforementioned Tutorial. Fun stuff!
