Meshwork Release Notes

October 22, 1999: version 1.4.1

• added support for textures in POV-Ray export (user must create PNG files called texture0.png through texture7.png, similar to VRML export)
• fixed a bug which caused texture images to not be saved when doing a "Save As"

October 2, 1999: version 1.4

• added 2D Polygon tool
• added Grid button, allowing for adjustable alignment grid
• fixed bug which caused symmetry relations to be broken when switching camera views

August 28, 1999: version 1.3.2

• fixed bug which caused most distant of overlapping points to be selected in top, bottom, front, and back views (now always selects closest of overlapping points)
• improved performance & reliability of Undo, Revert, window-closing, and other things which deallocate geometry data
• Undo/Redo menus are now properly updated when switching windows or opening new windows
• fixed bug that caused Undo/Redo to get confused after saving a file (note: the undo buffers are cleared when saving, so you still can't undo past the last save point)
• Show/Hide commands are now undoable

August 23, 1999: version 1.3.1

• fixed Import bug which corrupted coordinates with more than 9 digits past the decimal place; affected DXF written by Infini-D, and possibly others

August 14, 1999: version 1.3

• coordinates are now editable in the toolbar -- just click or tab to enter, and click outside the coordinate panes when done
• fixed two bugs with Subdivide command: display was not refreshed, and material assignments were lost
• fixed bug: pressing '2' on the numeric keypad did a Revert (!) (old debugging code that should have been removed long ago)
• 3D Preview window can now be closed with Escape or command-period
• added a "close base" option to the Create Cone dialog
• added Appearance Manager support

July 11, 1999: version 1.2.2

• Create Cylinder dialog now has an option to create closed (capped) ends

June 19, 1999: version 1.2.1

• attempting VRML Import in 1.2 dropped into the debugger (or exited with error type 12 if no debugger was installed); fixed by disabling the VRML Import item

June 14, 1999: version 1.2

• added VRML export -- all modeling features are supported, though you must save your own texture files (see the reference manual for details)
• added support for non-Meshwork resources, such as the 'ckid' resources used by version control systems

June 6, 1999: version 1.1.3

• fixed a bug causing points dragged with the mouse to move in large increments when the scale is magnified
• fixed a bug in the 68k version causing erroneous coordinate values in points moved with the arrow keys
• improved the robustness of the 3DMF export when dealing with degenerate triangles (triangles with two vertices in the same place)
• improved the Combine command to remove degenerate triangles
• improved the Lathe command to automatically remove degenerate triangles caused by points on the axis of the lathing
• fixed a serious bug causing any previous geometry to get munged by the "Sphere 2" command
• made Sphere 2 properly undo/redoable

April 24, 1999: version 1.1.2

March 7, 1999: Version 1.0.1

• Normals are now recomputed after scaling, relaxing, or tensing.
• Material assignments are now undo/redoable (but note that changes to material properties are persistent, i.e. not undoable)
• Bug involving undo/redo across a change in symmetry button settings has now been fixed.
• Bug involving incorrect deletion of mirrored points (i.e. with symmetry buttons) has now been fixed.
• Spurious "end of file" error when reading a Meshwork file without a resource fork has been fixed.
• 3D Previewer is now a little smarter about reporting when it's unavailable due to old or improperly installed QD3D.

• full balloon help
• several new import/export types
• numerous small improvements
• finished documentation

November 4, 1998: Version 0.9

• implemented Copy, Paste, and Clear functions for mesh data
• added cool (and more functional) about box
• changed display of selected vertices in anaglyph view
• implemented standard mappings for keys F1 - F4

  • random UV coordinates were shown when null material was selected
  • command-clicking a material selected its faces, but not deselect others (it now does so unless you also hold the shift key)
  • when doing Deselect All command, mirrored points were not properly refreshed
• began new, greatly expanded documentation; currently only reference section (i.e. section 3) is written

• added depth sorting of triangles (most extremely very cool)

July 19, 1998: Version 0.3
This is the first release with some support for texture mapping. It's still crude -- it allows only one projection type, and doesn't export the texture to POV-Ray (though it does export it to 3DMF). But it's a good foundation. Other changes:

• vertices can now be shifted with arrow keys
• vertices can now be dragged around with the mouse
• improved vertex selection behavior (now follows Mac standard for clicks, shift-clicks, and drags)
• fixed cosmetic bugs when "Drag Edges" or "Draw Vertices" is off
• confirmation upon closing an unsaved window
• Material options dialog box substantially expanded.
• Miscellaneous small bugs fixed in the code.

July 12, 1998: Version 0.2.1
This is mostly a maintenance release -- I discovered several bugs after yesterday's release (cringe!). But I've also thrown in a feature for good measure:

• added "Draw Edges" and "Draw Vertices" options in Display menu
• fixed bug which caused Meshwork to quit upon shift-clicking nothing
• fixed bug which set scale to 1 upon camera switch
• fixed bug which caused new vertices to be misplaced except in front view
• changed view definitions to match QuickDraw 3D Viewer

July 11, 1998: Version 0.2

• Fixed several minor bugs
• Added material configuration (option-click in material palette)
• Added material color and smoothness to POV-Ray and 3DMF export
• Changed file format to support smoothness/color info

July 8, 1998: Version 0.1

• First pre-release
