BUGS
----
o Some invalid DXF data gets pass the import checks and breaks the tessing code
o Broken polyhedron() entities are not correctly detected and cause CGAL segfaults
o Tesselation via GLU sometimes produces strange results
o Non-manifold objects make CGAL crash (e.g. two cubes which touch at one edge)
o Export STL: Exports existing CGAL model even though the current model is changed, but not CGAL rendered
USER INTERFACE
--------------
o Preferences
- Beautify color schemes
- Color schemes read from file
- Color scheme editor
- wireframe width
- pointsize
- OpenGL params
- Default language feature settings
- Auto-view CSG/thrown together on load
o Export etc.: automatically add missing extension as in SaveAs
o Mac OS X:
- universal binary -> fix cgal and opencsg
o MDI
- Think about how to do MDI the right way
- Quit vs. Close MainWindow.
Today Quit just closes the current window and there is no close function
- Ctrl-W should close the current dialog, not the current main window
-> implement as for Preferences?
- Menu bar handling:
Mac: share menubar among all top-level windows
o 3D View
- Improve mouse rotation
- Add modifier key combos to handle pan on 1 mouse button systems
- Show grid
- 4 x split view w/orthogonal cameras?
- Quick highlighting of object under the cursor in the editor
- View All
- overlay indicator displaying current view mode
o Editor
- Autocompletion/hints for builtin (and user-defined) functions/modules
- builtin quick function reference/help
- Drawer/popup with all modules/functions listed which can be inserted into
the editor by clicking or drag&drop -> icons in toolbar?
-> This would be moving in the direction of a traditional CAD GUI
and needs a fair bit of thinking.
- More infrastructur for external editor (or is the reload good enough?)
- Evaluate QCodeEdit (http://qcodeedit.edyuk.org)
- Display some kind of line wrap indicator
- Couple the source code to the AST to allow highlighting selected elements
in the source code in the 3D view
o Misc
- Fix current_win hack
- Reload and compile: Ask for confirmation if file is locally edited
(make this configurable in preferences?)
- Save: Ask for confirmation if file has been externaly changed
- Rename OpenCSG and CGAL to smth. not specific to the underlying libraries
(e.g Preview, Render)
ENGINE
------
o Primitives
- Springs, spirals (requested by Cathal Garvey)
- (TTF) Text
o 2D Subsystem
- Add generic 3D->2D projection statements
- 2D->3D using clipping plane
- Performance: Is it necessary to union children before extrusion
when compiling? Can this be postponed to CGAL evaluation time?
o Built-in modules
- extrude*: Allow the base 2D primitive to have a Z value
o Advanced Transformations
- Add statement for 2D and 3D minkowski sum
- Add statement for refinement via surface subdivision
- Add statement for intersections in cartesian product of childs
o Function-Module-Interface
- Pass a module instanciation to a function (e.g. for a volume() function)
- Pass a function to a module instanciation (e.g. for dynamic extrusion paths)
o Language Frontend
- Allow local variables and functions everywhere (not only on module level)
o DXF Import
- Support for POLYLINE entity
- Support for SPLINE entity
- Support for LEADER entity
- Support for MTEXT entity ?
- idea: DXF inline - convert from dxf to OpenSCAD syntax -> parametrize dxf content
o Mesh optimization on STL export
- Remove super small triangles (all sides are short)
- Replace super thin triangles (one h is short)
o Misc
- Add symbolic colors to the color() statement
- Go through default values of parameters (e.g. cube() has x,y,z=1 while linear_extrude() has height=100)
o Grammar
- dim->name -> dim->label
- A random(seed) function
- import_*() -> *_import() (consistent prefix vs. postfix)
- linear_extrude()/rotate_extrude(): Cumbersome names? -> (extrude, revolve, lathe, sweep ?)
CODE
----
o Refactor from MainWindow:
- CSG data structure (compiled model)
- CGAL data structure (compiled model)
o C++-ify
- Use smart pointers where it makes sense (e.g. instead of homegrown refcount,
and to get memory ownership under control)
- Use static_cast instead of C-style casts
o dxflinextrude and dxfrotextrude could share code
o Consider decoupling DXF-specific functionality from the 2D subsystem
o Make the interfaces from OpenSCAD and OpenCSG and CGAL cleaner to facilitate
experimentation with other frameworks (ref. Nef_polyhedron_2() problems)
INFRASTRUCTURE
--------------
o Think about making external libraries easier available. Probably mostly convenience.
o Use a logging framework to get debugging/info output more under control?
(check log4j, google project)
MISC
----
o Collect "all" available OpenSCAD scripts from the internets and batch convert them
to STL to assist with robustness testing.
