Understanding what Graphics 2.0 effects do (How they map to Photoshop?)

I have been reviewing all the terrific new features of Graphics 2.0. One thing that we are particularly interested in, are all the new effects that can be done:

http://docs.coronalabs.com/tachyon/guide/graphics/effects.html

However, as a none-artist, it’s been really challenging for me to understand what all the various effects are, and how they can be used for the projects we have in the pipeline. It appears to me, many of the effects have corresponding effects in Photoshop. If so, would it be possible to get a mapping of what the equivalent is in Photoshop?

This would really help us work with our artist to speak the same language, and to explore together how to apply these to our projects.

Any other suggestions for how to get a a handle on understanding what these effects do visually (and how to most effectively communicate with our artist), would be much appreciated!

Thanks,

Andrew

Most of the filters are named the same as their Photoshop equivalents or close enough that one could figure them out.   I set up a small app that basically had a timer that every 2 seconds it would change the filter to the next one in the list and put the name of the filter in a display.newText() so I could see roughly what the effect is.  What it didn’t do was let me easily change the effect parameters (like how much saturation or what angle to use on the color hue change)

This could also be a good idea for a blog post too.

Ok, but apparently not all filter effects are even documented yet?

For example, I am trying to find something about filter.normalMapWith1PointLight, but there is nothing here:

http://docs.coronalabs.com/tachyon/guide/graphics/effects.html

Is it implemented yet? Or is it just undocumented?

Oh, I found it. Its called composite instead of filter :stuck_out_tongue:

Hi @renato.bugge,

Check out the latest tutorial on composite filters, it should be helpful as a reference:

The engineers are updating the docs for this and I think we are planning a tutorial around these two filters specifically since they can create way cool lighting effects.  If you have the G2.0 sample apps there should be a folder called composites that has samples of these in action.
