Move light position

[kerautret]

add a new possibility to move light source position (an x-axis (resp. y-axis) mouse move changes the azimuth (resp. inclination angle) of the light source).

[kerautret]

The light source direction is also displayed during the light source move.

... source using the mouse (with SHIFT key modifier) in Viewer3D

[kerautret]

better thanks ;)

[dcoeurjo]

Nice feature ;) i'll test it

[kerautret]

done ;)

[dcoeurjo]

x-y seems to be ok but I don't understand the "z"
BTW add the key binding (shift+CMD on mac..) in the changelog
and add something to say that the light always looks at (0,0,0)

[kerautret]

the position z of the light should change when you move the mouse according an y move (upper or lower).
ok for the key

[dcoeurjo]

euh.. I don"t get it.. Are x (resp. y) moves increasing the phi angle (resp. theta) in a Euler representation ?

[kerautret]

yes exactly

[kerautret]

I fix a pb of direction update from the draw(), now it should be finer. The light source direction is always defined in the main system coords, and don't move with the camera. I think that this choice is better to simplify the user interaction with the definition of move.
Hope that it is also fine for you?

[dcoeurjo]

perfect!! thanks a lot

[dcoeurjo]

Would it be possible to add a line in the documentation ?

[kerautret]

it in the help function but you mean in the main section ok I add it

[dcoeurjo]

I meant in the module documentation

[kerautret]

done

[dcoeurjo]

great
