Dynamically set shader filter variables

That would be awesome !

We could link / insert it to the vimeo page (https://vimeo.com/vimix), or I was also thinking of a 'Made with vimix' section in the wiki. Let's see.

In 0.2 version of my module there are cloneuniform messages:

Ah! So I had an old version installed because I installed through apt. Using Flatpack got me to the latest release and solved the issues!

[brunoherbelin]

Thanks for positive feedback!

Yes, what you ask is supported by vimix in latest version 0.8.2d (currently being submitted as snap and flatpak releases, otherwise accessible from source)

Example; send /vimix/#0/uniform sf pix 0.9 to set the value of the uniform variable 'pix' to 0.9, assuming source #0 is a clone source and the shader code defined a uniform variable called 'pix'.

More info on the wiki OSC doc

Incredible! Thank you so much: this is about to take my game to the next level. I'm running a very cool show on Thursday - if video of me running Vimix in a live context would be helpful to you, I'd happily shoot some and send it your way for promotion.

I've got the plugin going - it rules! I'm using a uniform float and the uniform clone mapping but it's not affecting it. Any ideas?

[brunoherbelin]

Two things to check

• declare uniform without initialization value (this prevents the reset to 0.25 each time GLSL is loaded)
• In the last version of vimix, when a uniform is registered (after build), there is a slider in the left panel properties of the clone (if you don't have the slider for EFFECT_1, then upgrade)
• there should be a log of the events in vimix: not sure how verbose it is in Release (otherwise compile with Debug)

@brunoherbelin how about releasing Vimix version 0.9 ?
There are actually many new features in the development version.
