Changeset 2447 for code/branches/objecthierarchy2

Timestamp:

Dec 14, 2008, 8:13:43 PM (16 years ago)

Author:

Message:

• Removed directional-light-hack from Scene
• Many changes in Light, works in all game-modes (standalone, dedicated, server and client)
• Fixed a bug which caused clients to not having shadows

There's still a big problem, bug I can't explain it.

+                Quote from the Ogre API:
+                Lights normally get fainter the further they are away. Also, each light is given a maximum range beyond which it cannot affect any objects.
+                Light attenuation is not applicable to directional lights since they have an infinite range and constant intensity.
+                This follows a standard attenuation approach - see any good 3D text for the details of what they mean since i don't have room here!
+
+                Quote from the Ogre wiki:
+                "Using these numbers, the light has 100% intensity at 0 distance, and
+                trails off to near black at a distance equal to the Range. Keep in mind
+                that most of the light falls in the first 20% of the range."
