I tested the spray tool and here is my UI enhancement proposal.
If Pierre-Antoine is not available to work on this, I can find time the this week to do it. Please, tell me if someone already worked on this.
The Spay Toolbar would be :
Mode [] [] [] | [Distribution] | Width ----- [Pressure] | Amount ---- | Variation : Rotation [xx] Scale [xx] | Ring Radius ---- | Dispersion -----
Mode : (Buttons) "Copies", "Clones" or "Single Path"
Distributions : (DropDown list) "Uniform" or "Scattered Ring"
Width : (slider) 0 -- 100
Amount : (slider) 0 -- 100
Rotation variation : (numeric field) 0 --100
Scale variation : (numeric field) 0 --100
Ring Radius : (slider) 0 -- 100 (available only with "Scattered Ring" distribution) default to 0
Dispertion : (slider) 0 -- 100 (available only with "Scattered Ring" distribution) default to 75.
And here are the explanations :
* "More Options" panel removed because not necessary.
* "Uniform" distribution is simpler to understand and will be sufficient in many cases (OK I've no proof, but I think). But I think the "gaussian" one couldbe use to acheive some nice and more tuned effects. So choice should be accessible easily.
* rename "Gaussian" distribution into "Scattered"
* rename "Population" into "Amount"
* "Scale Variation" and "Rotation Variation" are very important parameters. Instead of asking for a min value and max value, just ask for one percentage value : 0% means no variation, 50% means a variation between 0.5 and 1.5, 100% means a variation between 0 and 2.
* After some testing, I'm not sure the "Ratio" and "Angle" parameters could be useful. I would remove them.
* rename "Mean" and "SD" into "Ring radius" and "Dispersion"
I'm sorry if this seams to cut down some efforts made by the students (especially for the "ratio" and "angle" parameters).
Tell me what you think, I will be able to work on this but I want to be efficient and avoid duplicated efforts.
