... illuminate/dark an scene?
Posted: Fri Aug 31, 2007 1:26 am
That's something that get around my head from long time ago:
What's the best way to give light (or darkness) to an scene using AS capabilities?
I have investigated about that and I think there are some techniques that solves the situation. What I want you to help me on what's the best choice.
Let's assume that your 'scene' is in a single vector layer (otherwise encapsulated with a Group folder). There are two posible situations: A dark scene you want to light or a light scene you want to dark. As well as one implies the other we can study both at the same time. The options are:
1) Add a shape in the same vector layer (white like or black like color to light or dark the scene). Give it a proper alpha value and apply a soft edge to the shape (optional). It would produce a lighter or darker area where it lies. It is not useful if you want to light and dark an scene at the same time unless you take account of the position and shape of the dark and soft shapes at the same time.
2) Add a shape with similar color values BUT in other vector layer. Apply a blending mode to the layer that allow light or dark the scene properly. For example to light an scene I have found very useful the Overlay or Illuminate blending modes for a "white like" overlapping shape. It is quite interesting due that you can use different blending methods for the light and the dark layers and can be aaplied at the same time over the scene, giving opposite results and anulating one to the other in the proper area. Also blurred areas can be cut using masking to simulate some tipes of rays (maybe coming form a window). Even this cut can leave different ammount of blur to the lighted area depending on if the blur comes from the mask or from the lighted shape itself.
3) Same like avobe but give the blur to the layer instead of the shape (with this you can animate the blur of the light/dark to give a more nice effect)
Do you have other way of adding light/dark to your scene?.
Related with this: What lumminace level should I use for the color scheme of my scene? If I choose it so dark it would be difficult to light adding 'light' shapes? Or if I choose them so clear colos could be very difficult to dark them properly?
Finally, I'm sorry for not post examples but I cannot access to AS just now.
