ChangeLog

@@ -14,6 +14,7 @@ Scenery :
   * Added sun halo control.
   * New cloud model with 2 noises : one for the global shape and one for edges.
   * Terrain shadows have been improved and are now configurable.
+  * New sky model (based on Preetham's work).
 
 Rendering :
   * New texture model (perpendicular displacement and thickness).

TODO

@@ -7,7 +7,6 @@ Technology Preview 2 :
 - Keep skydome lights in cache for a render.
 - Disable form fields when no layer is selected.
 - Add buttons to restore "auto" default values in tabs and dialogs.
-- Remove color gradations (replace with automatic boolean and simple colors).
 - Replace zone ranges with curves (with curve input and curve dialog).
 - Interface for textures thickness, slope_range and thickness_transparency (and correct slider ranges).
 - Add "hardness to light" and shadow control ("minimum lighting") to material.

 Technology Preview 3 :
 - Restore render progress.
 - Implement High Dynamic Range.
+- Implement Sub Surface Scattering for water.
 - Use bicubic interpolation for antialiasing.
-- Improve large render/antialias memory consumption.
+- Allow for larger renders/antialias (will need several two-pass chunks).
 - Add basic vegetation system ?
 - Texture shadowing and self-shadowing ?
-- Improve sky rendering (colors and light halo).
 - Add a progress indicator on previews.
 - Multi threaded first pass.
 - Mark modified tabs and ask for losing modifications (idem for layers).
 - Fix potential holes in land rendering.
-- Progressive final render.
+- Progressive final render (increasing resolution, for second pass only).
 - Propose several backgrounds for water preview (grid, sinus...).
 - Water and terrain LOD moves with the camera, fix it like in the wanderer.
 - Improve 3d explorer
