@ -11,19 +11,22 @@ Technology Preview 2 :
- Add a material editor dialog.
- Add a zone editor dialog for localized textures.
- Add a terrain modifier dialog with zones.
- Use the curve editor in noise editor
- Add a noise filler (and maybe noise intervals ?).
- Fix the distorted sun appearance.
- Improve curve editor.
=> Add curve modes
=> Improve curve rendering
=> Add axis labels
=> Add axis labels and grid
=> Add logarithmic mode
- Improve 3d explorer
=> Restore LOD and intelligent poly count
=> Restore LOD and intelligent poly count (and raise max tessellation)
=> Interrupt chunk rendering when quitting dialog
=> Don't display the water if it's below all ground
=> Try to overcome the near frustum cutting
=> Disable texture reflection of light (dependant on camera location)
=> Add toggles (for water...)
=> Max texture size should depend on GPU memory available
- Water and terrain LOD moves with the camera, fix it like in the wanderer.
- Pause previews drawing of main window when a dialog is opened.
- Interrupt preview chunk renderings that will be discarded at commit, or that are no more visible.
