Fixed a few spot light settings. The cut off angle previously uses radian instead of degree. Drop off rate can now be negative, which will make the spotlight a special non attenuating 'directional spotlight'. Note that the drop off rate attenuates the light intensity with exponential rate. It appears that the initial drop is much faster comparing to later. I have changed the spin box step to 0.01.
I haven't realized previously the power of this shading mode when using freecad. When working with assemblies or other complex parts it gives a REAL visual advantage enabling me to concentrate on the workflow instead of squinting at the screen, trying to figure out where one component meets another. This is why , in my opinion, the drop shadow mode should be up high as importance for the merger in freecad trunk and a great value addition. I also think it could be a excellent tool as pr/publicity for spreading freecad in to the wild. Looking back at the history, Blender and Krita have exploded in popularity after similar visual changes that generated cool screenshots which in turn got people interested in giving a real try at using the application.
One simply got to love the shadows in the pool.
Directional light now should have the same performance as spot light. This is another coin3D problem.
Indeed I get the same performance now on my hardware.
Also, I cant put my finger on what it is, but the shading of the models with the directional light now is just......better.
I have added a new setting 'GroundShading' for that, and can be configured in preference dialog. When disabled, the shadow will have no shading. You can use the ground color to change the shadow color.
I find this mode to be more realistic in some cases and less distracting while having at the same time the clue of the shadow underneath the model. Thank you.
