- HyperCuber 2.0
- by Greg Ferrar
-
- HyperCuber is a program which displays and rotates higher-dimensional
- objects (like four-dimensional "hypercubes"). It requires a 68020
- processor or better, a math coprocessor, and System 7 or better.
-
- Complete documentation for the program is contained in the HyperCuber
- Manual file, which is a stand-alone document created with DocMaker.

- Enjoy!

- ================================ To Do List ==============================
-
- Here are some plans for the future. I don't promise that any of them will
- ever get done, but if you think of something that should be on here that
- isn't, or see something here that should not be, let me know!
-
- • Solid polygon modelling (as opposed to wire frame). If I do this, I will
- probably try to make it work arbitrary dimensions (i.e. hidden solid
- removal in 4-space), so this isn't an easy one.
-
- • Eliminate floating point math
-
- • Command to change window to standard screen sizes (useful for making
- startup screens)
-
- • "predefined" rotations; user would set parameters of rotation (bounds,
- increment) and HyperCuber would rotating the object continuously.
-
- • Other options for creating object (perhaps create new object based on
- mathematical functions).
-
- ================================ Version History ==============================
-
-
- Version 2.0 (released May 3, 1994)
- -----------
-
- • Changed manual format from Word to DocMaker.
-
- • Added user-defined objects (using object file).
-
- • Added support for objects of arbitrary dimension. This was the biggie, and
- much of the code had to be rewritten. A lot of the other changes were
- a direct result of this one.
-
- • Added support for viewing multiple objects simultaneously.
-
- • Totally changed and improved Keyboard Controls... window
-
- • Totally changed and improved Mouse Controls... window
-
- • Added "Create N-Cube" command
-
- • Split controls into multiple windows, one dimension per window
-
- • Changed the way the Perspective works
-
- • Lost the ability to display axes (sigh...I'll try to add it back later).
-
- • Improved Copy command so it copies object-oriented pictures if antialiasing
- is turned off, and copies bitmap pictures if antialiasing is turned on.
-
- • Lots of other minor changes
-
-
- Version 1.2 (limited release)
- -----------
-
- • Removed support for non-Color QuickDraw machines (it never worked very well
- anyway...). Removed support for 68000 machines, since they don't have Color
- QuickDraw.
-
- • Added fast antialiasing of line segments.
-
- • Added an offscreen bitmap for fast window updating
-
- • Slightly changed default left eye color so it won't cancel itself out.
-
- • Added "click and drag"-style control of the viewpoint (like MacMolecule).
- Added Mouse Controls... menu item for customizing this.
-
- • Made scroll bars "live," so the images changes dynamically while the bars
- are dragged. Along the same lines, improved the "dynamicness" of the
- number to the left of each scroll bar. Basically, whatever you do, the
- number, the scroll bar, and the image will agree at all times.
-
- • Made scroll bars wrap around, so that an attempt to go beyond the range of
- the scroll bar will wind up at the other end. Shortened range of scroll
- bars to eliminate redundant angles (necessary before in order to allow long
- rotations; wraparound bars allow infinitely long rotations, if desired).
-
- • Added Keyboard Controls... menu item for customizing keyboard rotation
- control.
-
- • Gamma-corrected the antialiasing table-- yields MUCH better looking lines,
- with no affect on speed.
-
- • Added menu item to make windows full-screen
-
- • Added menu item to hide or show the menubar.
-
-
- Version 1.1.2 (never released)
- -------------
-
- • Added support for non-Color QuickDraw machines.
-
- • Added a different version for machines without a 68000 or FPU.
-
- • Added a Default button to the Colors window, to reset colors to their
- default values.
-
- • Merged this HyperCuber Version History file and the README file.
-
- • Limited values of delta and rho to a smaller interval, to prevent
- arithmetic overflow when drawing.
-
-
- Version 1.1.1 (released August 21, 1993)
- -------------
-
- • Added checking for Color QuickDraw, and added code to exit gracefully
- if Color QuickDraw is not present. I'm not sure why it requires Color
- QuickDraw (or if it does) but the folks at UMich have a 68030-accelerated
- Mac SE which crashes. This change shouldn't affect many people, since
- there are few non-Color QuickDraw machines which have 68020s or better.
-
-
- Version 1.1 (released August 19, 1993)
- -----------
-
- • Added keyboard control of all the scroll bars.
-
- • Colored the hypercube based on x coordinated, to improve perception of what's
- going on.
-
- • Moved the options (check boxes and radio buttons) to the Options menu.
-
- • Moved the scroll bars to a separate Controls window, which can be hidden.
- Also rearranged scroll bars to make them as compact as possible. This makes
- it much easier to use HyperCuber on small-screen Macs.
-
- • Changed name of window from "HyperCuber Window" to "HyperCube".
-
- • Massively rehauled the internal class structure. This makes no difference
- at present, but the program is now more easily extendable to multiple
- windows, multiple views, and multiple documents (objects).
-
- • Implemented Save As PICT File option.
-
-
- Version 1.0.1 (released August 14, 1993)
- -------------
-
- • Introduced code to determine processor type, existence of FPU, existence
- of System 7.0 or later, etc., and to abort if HyperCuber could not run in the
- environment under which it had been launched.
-
- • Improved window placement routines so windows can not be placed off-screen,
- and so they will would automatically fill the screen if no preference file
- exists or if the preferred location of the window is off-screen.
-
- • Added version number to About... window.
-
- • Added two cases for About... window: when there is plenty of memory, the
- nifty (but memory-intensive) bitmap picture is drawn. When memory is limited,
- the slightly-less-nifty object-PICT is drawn instead. This lowered memory
- requirement from 450K to 300K (anything below 450K loses the bitmap About...
- picture).
-
- • Fixed (hopefully) a bug which could cause crashes on some machines when
- changing preferences. I was not able to reproduce this bug, but I revamped
- some questionable sections of the preferences code to make them safer.
-
-
- Version 1.0 (released August 11, 1993)
- -----------
-
- First released version
