[Axiom-developer] 20080607.01.tpd.patch (make viewalone from bookvol8)

[daly]

Make the viewalone function from bookvol8.
A test case (parabola.view) is created from the data description
in the Graphics File Format chapter and written to the $AXIOM/graph
directory.

-\section{General Comments}
-This directory contains the C source code for the Scratchpad's
-graphics. Comments given to the maintenance program refer to 
-version numbers. The versions are documented below, starting with
-version23.
-\begin{verbatim}
-version23: (first version after returning from Europe)
-   added a $DEVE environment variable - if it exists, the viewport manager 
-   tries those executable files first; if it was unsuccessful or, if the 
-   $DEVE variable was not defined, the $SPAD variable is used tube.c: 
-   changed order of crossedLines(p,q... to crossedLines(q,p... in order to
-   use segNum info (which segment of the second polygon the first polygon 
-   crosses) and using splitPolygon() rather than splitAndMove()
-   tube.c: changed crossedLines() to generalPartialSplit() - an algorithms 
-   i hope would work. it is not taken from any literature as all the 
-   literature i have looked into and tried out had design flaws or lacked 
-   precise specifications (including Foley & van Dam volume I, Newman & 
-   Sprouill and others) 
-   viewport3D.c: xPts now malloced as a global variable in makeView3D and 
-   not freed up at the end. quadMesh is also not freed anymore (shouldn't 
-   be as it was changed to a global some time ago).
-   made eyeDistance (3D stuff) into a float (from integer)
-   added outlineRender (outlineOnOff in actions.h) field. note that this 
-   and the previous change both affected the following files:
-      view3d/: main.c, process.c, viewport3D.c, spadAction.c, write.c
-      viewman/: fun3d.c make3d.c
-      viewalone/: spoon3D.c spoonTube.c
-      spad/: view3d.spad (viewport3D, makeViewport3D and the Rep)
-   3D: ability to write Stellar recognizable data files for Tube types
-   spad additions: write(v,fn,listOfTypes)
-   fixed perspective, added min/max range of eyeDistance
-
-version24: view3d/tube.c: put in calculations for xmin,xmax,ymin,ymax
-   >>> took them out again - doesn't the viewport manager do that?
-   polygon list saved if previous render/opaque (hidden surface)
-   was completed so that subsequent draws would be faster
-   view3d: added NIL(pType) macro which checks for a null pointer
-   >>> need same change in view2d (after testing)
-   totalShades is now a global variable (to be decremented if color trouble)
-   >>> need same change in view2d (after testing)
-   cleaning up: added exitWithAck(info,size,i) macro to send spad 
-   acknowledge right before exit of a troubled program. this
-   should avoid some of the causes of entering spad break loops
-   not enough colors could be allocated; now, only a message is given.
-   viewman: adding checks for abnormal exits of child processes (from
-   people who use the "Cancel" command from the X server).
-   deadBaby() and brokenPipe() in the works.
-   view3d: hey! there was a bug in the projections: with perspective on,
-   it turns out the Z-axis was rotating opposite of the rest of 
-   the system...?...
-   fixed perspective
-   added box (with back face removal)
-   function of 2 variables now has it's own substructure, like tube, and
-   shares the (now) general hidden surface subroutine used for the
-   tube stuff when the perspective is turned on (when perspective is
-   off, a simple back to front routine is sufficient and fast but the
-   property that allows that is not preserved in the perspective projection)
-   seems like (in tube.c) the overlap list property is not preserved (see
-   notes) so now, routine needs to check, for polygon i, polygons
-   i+1 through N, always.
-   affects ALL: added deltaZ to all the stuff 
-   (spad, viewman, viewalone, view3d) - though not used yet
-   error messages: if the .Xdefault not found (or .Xdefault wasn't defined) 
-   then view2d and view3d will a predefined default set of fonts. it that
-   still doesn't work, a (more or less useful) error message is displayed
-   and an error signal is sent to Scratchpad to prevent a freeze-up situation.
-   viewpack.spad (package VIEW) and view2d.spad (domain GRIMAGE) now check for
-   lists that contain illegal empty lists (i.e. point list contains nothing).
-   warnings are issued for lists containing both legal point lists and empty
-   point lists, errors are issued for lists containing nothing but empty lists.
-   made spadcolors30.c into an archived library by the name of libColors.a, 
-   source file changed to spadcolors.c; makeColors' arguments have changed 
-   and now returns the number of colors allocated - not a pointer to the 
-   pixel map
-   saymem, check, etc. moved to util.c for library archive
-   added a view.h file, with macros to be used by all view programs
-   monoColor(x) macro (in view.h) replaces spadColors[x] calls in case 
-   display is monochromatic (in global variable mono)
-   tube.c: connecting of slices - polygon points changed to outline the 
-   rectangular regions without the diagonals (may be prettier when outlines 
-   are sketched...slightly, if no split occurs).
-   clipping model: both against the hither plane as well as with a 
-   clipping volume
-   viewport3D.c: made polygon list for functions of two variables so
-   that it could call the general hidden surface algorithm (in tube.c) as
-   well (turns out that back to front property of 3D explicit equations is
-   not preserved when viewed with perspective)
-   added volume.c, volume.h for the frustrum (perspective), projected clipping
-   and clip volume interface
- 
-version25: 
-  view3d: added long jump to address signals that arrive while in the
-          XNextEvent call. spadSignalHandler() now calls spadAction()
-          if a signal is received.
-  view2d: added query button and messages for each graph image
-          (viewport2D.c, control.c, process.c)
-  view3d: tube.c: improved speed of drawPolygon by creating overlapped
-          list for unmoved polygon, and list for moved polygon that
-          may be smaller than the entire list. 
-          see "Notes on the Depth Sort Algorithm" for strategy, etc.
-          tube.c: moved the resetting of the variables relevant to recalc
-          from process.c to tube.c (rotated, switchedPerspective, 
-          changedEyeDistance)
-  GraphImage now supports 2D primitives like point(), component(), addPoint()
-  ViewportDefaultsPackage now exports viewXPos() and stuff; all references
-  to integers have been replaced by the more restrictive subdomains 
-  (e.g. PositiveInteger, NonNegativeInteger)
-  ViewportPackage has dwindled to just drawCurves() and graphCurves()
-  view2d, view3d: put in more robust signal handling routines so that
-  signals from the viewport manager (Scratchpad) are all processed properly.
-  the condition where the user is not allowed to use the control panel of the
-  viewport that Scratchpad is sending commands to no longer exists!!!! wow!!!
-  simultaneous processing without a race condition occuring (sorta) should
-  not occur anymore.
-  view3d: modification to keepDrawingViewport() so that signals also causes
-  a return of no. this allows Scratchpad input files to be indistinguishable
-  from interactive commands from a control panel! (that is, drawViewport()
-  no longer need to complete the drawing if it was called from Scratchpad.)
-  view2d: spadAction(): now only redraws viewport if the info was received for
-  a graph image that is being shown
-  view2d: fixed up pick/drop hangup problem. the "dodat" variable in process.c
-  needed to be reset earlier, and in each separate routine (pick, drop and 
-  query) that required sequential button clicks (e.g. 
-  "Drop" + graph number "1").
-  view2d: added global variable queriedGraph - so that the last queried graph
-  will always be the one displayed.
-  view2d.spad: default to points off
-  added inverse and monochrome fields in .Xdefaults 
-  (e.g. view3d*monochrome : on)
-  BUG FIXED: clipping of wire mesh for tubes
-  view3d.spad: function of three variables for color specifications ==> changes
-  in viewman, viewalone, and view3d to accept additional information.
-  structure of fun2VarModel in view3d.h changes *** not backwards 
-  compatible with version24.
-  BUG FOUND: viewport3D.c still drawing the function of 2 variables
-  without perspective (painter's algorithm without processing) wrong!
-  BUG FIXED: this time, for shur. flipped quadrants II and IV to remedy bug 
-  found in painter's algorithm in viewport3D.c.
-  tube.c (view3d): changed routine that redraws quickly from the saved up list
-  of processed polygons from the hidden surface algorithm so that each polygon
-
-version 26: 
-  view3d: switched over to a generalized subspace points definition.
-  so far, wire meshes work for existing types. code in viewport3D.c and tube.c
-  are replaced by one more general in component.c; size reduced in half. 
-  include: modified=[view3d.h] new=[component.h]
-  view3d: modified=[viewport3D.c, tube.c] new=[component.c]
-  viewman: modified=[fun3d.c, make3d.c]
-  representation should also handle future 3D things - like space curves, 
-  points and stuff without new data structures.
-  NEED: take out unused code
-  component.spad there temporarily to handle the new representation on the 
-  algebra side point.spad deals with the new representation in more 
-  generality on the algebra side
-  NEED: interface to rest of algebra world
-  view2d: draw dashed line if ticks are too close. view2d: 
-  modified=[viewport2D.c]
-  coord.spad added for coordinate transformation
-  xspadfill.c in the src/ directory for shade dithering in color - affects:
-  src: modified=[spadcolors.c, spadcolors.h] new=[xspadfill.c]
-  view3d: modified=[globals.h, main.c, tube.c]
-  view2d: added tick labels for 2D
-  view2d: modified=[viewport2D.c]
-  view3d: tube.c replaced by surface.c and project.c
-  viewman: for hue and shade fields in 2D, spad is one based and the viewport
-  stuff is 0 based. modified=[makeGraph.c]
-  --- backed up on tape ---
-  replaced sprintf of XGetDefault value with direct assignment since 
-  XGetDefault may  return a NULL value which causes sprintf to freak out 
-  (xDefault is now pointer to char rather than a character array)
-  view2d: modified=[globals.h, main.c]   
-  view3d: modified=[globals.h, main.c]   
-  BUG FOUND: on the PS2, redraws of hidden surface with saved data (quickList)
-  bombs.
-  BUG FIXED: no more bombs of quick draws
-  view3d: modified=[surface.c (previously, tube.c)]
-  put in SIGTERM handlers so that a kill signal to viewman would cause it 
-  exit cleanly (that is, kill all the child processes and then exit)
-  viewman: modified=[viewman.h, viewman.c, cleanup.c]
-  view3d: modified=[main.c]
-  view2d: modified=[main.c]
-  viewWoman: modified=[viewWoman.c]

-version27: 
-  3D primitives: added type flag to polygon structure (for 3D primitives) - 
-  may or may not actually be used
-  include: modified=[tube.c]
-  added "#define smwattDefaultToFast" which, when defined, defaults to the 
-  simple back-to-front draw rather than the full depth sort processes 
-  (click middle button to switch)
-  BUG FIXED: title reading in viewalone (to add \0 on top of the \newline 
-  fgets reads in)
-  viewalone: modified=[spoon2D.c, spoonComp.c]
-  points in 3D stored as references (indices) into a pool of points
-  include: modified=[tube.h, component.h]
-  view3d: modified=[main.c, project.c, surface.c, component.c]
-  added (maybe last version...?) window manager override flag in override.h 
-  file which sets to true or false (e.g. Presentation Manager may need 
-  override=false)
-  BUG FIXED: after the 3D stuff saves the ordering of polygons, the quick draw
-  misses the last polygon...had to change doNotStopDraw flag to affect the 
-  subsequent polygon.
-  view3d: modified=[surface.c]
-  added a development header file for temporary defines
-  include: added=[DEVE.h]
-  part II:
-  BUG FOUND: 3D color bar goes off the positive end
-  BUG FIXED: the color bar error
-  view3d: modified=[process.c]
-  put XMapWindow after the drawViewport in make3DComponents - fixes the 
-  problem of having an empty viewport window come up with no well defined data
-  view3d: modified=[component.c]
-  view3d: initialize the numOfPolygons and polygons field right before they're
-  used (as opposed to whereever i had them before)
-  view3d: modified=[component.c]

 \section{Directory overview}
 \subsection{Environment variables}
 DIRS is a list of directories with the suffix {\bf dir}.
-DOCS is the same list with {\bf dir} suffix replaced with {\bf document}.
-CLNS is the same list with {\bf dir} suffix replaced with {\bf clean}.
 
 Thus if we have a new directory {\bf foo} add it to the {\bf DIRS}
 variable as {\bf foodir}. It will automatically be added to {\bf DOCS}
