paysages3d/TODO

Technology Preview 2 :
- Replace zone ranges with curves (with curve input and curve dialog).
- Interface for textures thickness, slope_range and thickness_transparency (and correct slider ranges).
- Render tab previews should not rerender when changing render options.
- Compute shadows only once for all textures at a same location.
   => Add an intermediary light status (two pass lighting).
- Add layer sorting/naming.
- Save GUI config (views, render params).
- Add an OSD ability on previews and use it for camera location and user landmarks.
- Add a material editor dialog.
- Add a zone editor dialog for localized textures.
- Add a terrain modifier dialog with zones.
- 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
- Improve 3d explorer
   => Store computed vertices in memory, using chunks
   => Compute the ground texture by chunk
   => Don't display the water if it's below all ground
   => Add the sun position
   => Try to overcome the near frustum cutting
- 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.
- Fix "RGB parameters out of range" (and segfault) on preview while moving render params fast in render tab.
   => May need to change the updateData system.
   => Previews need to be paused while updating data.
- When there are two previews in the same view, balance rendering between the two.
- Lock some previews together (eg: terrain height and colored preview).
- Find a new licence.

Technology Preview 3 :
- Restore render progress.
- Add antialiasing option (pay attention to memory usage).
- 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.
- Fix potential holes in land rendering.
- Progressive final render.
- If we can't remove clouds artifacts, blur them.

Release Candidate :
- Polish all features and UI.
- More translations.
