Is there a 'Print' like function in effect code editor?

Hello all,

I’m just getting my teeth into VVVV and loving it.

I am currently experimenting with writing new effects. I was wondering how one outputs a variable, array, etc, if they are looking to debug a variable in the code editor?

I understand you wouldn’t want to output a different value for every pixel that is visited. But for example, say you want to setup a gaussian blur and want to make sure the parameters for your blur are working correctly…

How would one ‘print’ or ‘echo’ or otherwise these values?

I’d appreciate any help,


Jamie :)

since shaders run on the GPU, you cannot debug them on the CPU, but there are some tricks you can use, like writing values into a floating point format texture and reading them with Pipet, or display the debug texture in a renderer.
