PRAM IS A LIST OF OPTIONAL ARGS FOR THE FUNCTION RES IS THE # OF POINTS PER LINE. SO THE PLOT WILL CONTAIN A TOTAL OF .RES * .RES POINTS THE DEFAULT IS 60,USE AS FEW POINTS AS POSSIBLE BECAUSE RUN TIME GOES UP VERY FAST WITH THE # OF POINTS. DSK IF THIS ISNT #FALSE() THE OUTPUT GOES TO A DSK FILE. FILE IS THE NAME OF THE DSK FILE IT IS A LIST OF THE FORM (''F1'' ''F2'' ''DSK'' ''DIR'') THE DEFAULT IS M3D OUTPUT. ALL ARGS AFTER THE NAME OF THE FUNCTION ARE OPTIONAL AND THE ROUTINE DEFAULTS ITS OUTPUT TO THE 4010 SCOPE YOU ARE USING. " " M3D 1 THIS FUNCTION TAKES AN N BY N MATRIX AND DOES THE SURFACE PLOT AND HIDDEN LINE ELIM. THE VALUES OF THE ELEMENTS SHOULD BE FROM 0 TO 400 AND INTEGERS. EXAMPLE >>>> $ " " M3DSK 1-2 THIS IS THE SAME AS M3D, BUT THE OUTPUT GOES TO A FILE. THE SECOND ARG IS OPTIONAL AND THE DEFAULT FILE IS M3D OUTPUT. " " CIRCLE 4 This draws a circle with center x,y and radius r and p pionts in it . " " DRAW 2 This draws from where the beam is to the coordinents given to DRAW. MOVE must be called befroe the first DRAW because it sets the scope in in graphics mode. the co- ordinents should be in the range of 0 -> 1024 " " ELIPSE 5 THIS WILL DRAW AN ELIPSE WITH IT CENTER AT X,Y AND SEMI-AXISES A AND B, WITH P PIONTS. " " FNCTG 3-6 This will plot the graph of any function of one varible. it will auto-scale unless you tell it not to. for example >$ $ will plot a(x) for x=-1 to 1 with auto scaling. $ will not scale for you " " LINE 4 THIS FUNCTION WILL DRAW A LINE FROM X0,Y0 TO X1,Y1 ,THE COORDINATES SHOULD BE IN THE RANGE OF 0 TO 1024. " " MINIMAX 1 THIS FUNCTION IS USED BY FNCTG. GIVEN A VECTOR OR LIST IT RETURNS A TWO ELEMENT LIST WITH THE MINIMUM AND MAXIMUM VALUES OF THE VECTOR. " " MOVE 2 THIS MOVES THE BEAM OF THE COORDINATES GIVEN. IT ALSO SET THE SCOPE IN GRAPHICS MODE SO IT MUST BE CALLED BEFORE DRAW. THE RANGE OF THE COORDINATES IS THE SAME AS DRAW " " PAGE 0 THIS ERASES THE SCREEN ON THE 4010. YOU SHOULD GIVE THE SCOPE ABOUT ONE SECOND BEFORE DRAWING MORE STUFF. " " PLOTV 2 THIS FUNCTION WILL PLOT TWO VECTORS OR LISTS AGAINST EACH OTHER. IT MOVES TO THE FIRST POINT AND DRAWS TO THE REST. AGAIN THE COORDINATES SHOULD BE IN THE RANGE OF 0 TO 1024. THE TWO VECTORS MUST BE OF THE SAME LENGTH $ $ $ " " POINT 2 THIS WILL PLOT A POINT AT X,Y. THE COORDINATES SHOULD BE IN THE RANGE OF 0 TO 1024. " " TERMINAL THIS IS NOT A FUNTCTION BUT SHOWS YOU HOW TO TELL MIGS WHAT TYPE OF TERMINAL YOU ARE USING. WHEN MIGS ASKS YOU WHATE TYPE YOU ARE GIVE IT ONE OF THE FOLLOWING CHARACTERS FOLLOWED BY A ESC. CHAR. TERMINAL .................. A ARDS OR IMLAC G GT42(PDP11-10) LOAD WITH PICTUREBOOK T TEKTRONIX "" M.I.G.S. DISPLAY COMPILER THERE IS NOW A USEABLE DISPLAY COMPILER IN MIGS. IT WILL ALLOW THE USER TO DO MANY OF THE THINGS THAT REQUIRED THE E&S BEFORE. AS WITH MIGS' PRIMATIVES IT WILL SUPPORT IMLACS, ARDS, AND TEKTRONICS SCOPES. THE DISPLAY COMPILER IS COMPILED, WHICH MEANS IT IS FAST AT THE PRESENTTIME. THE COMPILER AND PROCESSOR LETS THE USER CREAT A PICTURE (MCELL), ROTATE THEM, TRANSLATE THEM, AND SCALE THEM. SUBPICTURING IS ALLOWED TO ANY DEPTH. THE MCELLS CAN BE TWO OR THREE DIMENSIONAL AND WILL BE CLIPPED AND PROJECTED AS NEEDED. TO USE THE COMPILER AND PROCESSOR FLOAD RRS;MUDDLE INIT. FOLLOW MIGS' INSTRUCTIONS TO DEFINE THE TERMINAL THAT YOU ARE USING. NEXT TYPE 'Y' WHEN MIGS ASKS IF YOU WANT THE DISPLAY COMPILER. YOU MAY WANT TO FLOAD RRS;TEST GRAPHS TO PLAY WITH. THE FUNCTIONS THAT YOU NEED TO KNOW ABOUT ARE LISTED BELOW. FUNCTION ARGS DISCRIPTION ........ .... ........... MCELL 6 OR MORE THIS FUNCTION CREATS A MCELL (PICTURE) THE CALL IS > NAME IS AN ATOM WHICH IS THE NAME OF THE MCELL TO BE CREATED. THE TWO LIST ARENT USED YET BUT ARE NEEDED THE VALUE OF 3D DETERMINS IF THE MCELL IS 2 OR 3 DIMENSIONAL. IF .3D IS FALSE THE MCELL IS 2D. IF .BLK IS TRUE THE MCELL IS BLANKED. THE <-BODY-> CAN BE ANY VALID MUDDLE OBJECT OR OBECTS. HOPEFULLY THERE SHOULD BE SOME MIGS PRIMATIVES IN IT. AT THIS TIME THERE IS A KNOWN BUG IN MCELL, IF YOU GET AN ERROR YOU WILL PROBABLY HAVE TO RELOAD THE MIGS PRIMATIVES. TO DO THIS $,OR IF YOU ARE USING AN ARDS ''>$ DISP 1 OR MORE THIS FUNCTION WILL DISPLAY A MCELL. THE CALL IS >. NAME IS AN ATOM WHICH IS THE NAME OF THE MCELL TO BE DISPLAYED. THE <-XFORMS-> ARE THE TRANSFORMS THAT YOU WANT TO APPLY TO THE MCELL. THEY ARE OPTIONAL. CALL 1 OR MORE THIS FUNCTION CALLS A SUBPICTURE. IT MUST BE USED IN THE <-BODY-> OF A CALL TO MCELL. > NAME IS AN ATOM WHICH IS THE NAME OF A MCELL WHICH IS TO BE USED AS A SUBPICTURE. IT HAD BETTER EXIST BY THE TIME YOU DISPLAY THE MCELL THAT DID THE CALL. NOW HERE ARE THE TRANSFORMS THAT ARE CURRENTLY AVAILABLE. THEY MUST BE USED IN A CALL IN A MCELL OR IN DISP. NOTE MCELL EVALS THE ARGS TO A TRANSFORM, BUT NOT THE TRANSFORM ITSELF.SO IF YOU DONT WANT THE ARGS EVALED TILL YOU DISPLAY THE MCELL,QUOTE THEM. TRANSFORMS ARE ANY FUNCTION THAT RETURNS AN OBJECT OF THE FOLLOWING TYPE. FOR 2D #DECL((VALUE)]>>) FOR 3D #DECL ((VALUE)) WHERE THE FIRST TWO FIXS SHOULD BE 3 FOR 2D, AND 4 FOR 3D. TO TELL IF THE MCELL THAT IS BEING DISPLAYED IS 2D OR 3D THE TRANSFORM SHOULD LOOK AT <1 .3DSTK!-DISPCOM>. IF IT IS TRUE THEN THE MCELL IS 3D. THE TRANSFORM SYSTEM IS BASED ON HOMOGYNIOUS COORDINATES.THE VECTOR TO BE TRANSFORMED IS A ROW VECTOR WHICH IS MULTIPLIED BY THE TRANSFORM MATRIX ON THE RIGHT OF THE VECTOR (I.E. V*M). FUNCTION ARGS DISCRIPTION ........ .... ........... XLATE 2 - 3 THIS FUNCTION TRANSLATES A MCELL. .X IS THE NUMBER OF UNITS TO MOVE IN THE X DIR. .Y IS THE NUMBER OF UNITS TO MOVE IN THE Y DIR. .Z IS THE NUMBER OF UNITS TO MOVE IN THE Z DIR. (INTO THE SCREEN). IT IS OPTIONAL (Z=0) AND IS IGNORED IN A 2D MCELL. SCALE 1 - 3 THIS FUNCTION SCALES A MCELL. Y AND Z ARE OPTIONAL AND DEFULT TO .X. Z IS IGNORED IN 2D MCELLS. ROTZ 1 THIS FUNCTION WILL ROTATE A MCELL ABOUT THE Z AXIS. .T IS THE ANGLE IN RADIENS. ROTZ IS THE ONLY ROTATION THAT CAN BE APPLIED TO A 2D MCELL. ROTX 1 THIS ROTATES AMCELL ABOUT THE X AXIS. .T IS THE ANGLE IN RADIENS. ROTY 1 THIS FUNCTION ROTATES A MCELL ABOUT THE Y AXIS. .T IS THE ANGLE IN RADIENS. ONE NOTE AND THEN SOME EXAMPLES, THE ORIGEN OF THE COORDINATE SYSTEM IS AT THE LOWER LEFT CORNER OF THE SCREEN. THE VISABLE AREA IS BOUNDED BY THE RECTANGLE (0,0),(0,1023),(1023,1023),(1023,0). EXAMPLE 1 ;''CLEAR THE SCREEN''$ <> > ;''CREAT A MCELL CALLED TRI THAT HAS A TRIANGLE IN IT. TRI IS A 2D MCELL''$ >;''DISPLAY IT AT THE CENTER OF THE SCREEN.''$ EXAMPLE 2 <> > > > ;''MAKE A NEW MCELL CALLED NTRI THAT HAS THE TRIANGLE ROTATED 30 DEGREES AND MOVED TO THE CENTER OF THE SCREEN.''$ ;''LETS HAVE A LOOK AT IT.''$ EXAMPLE 3 ;''GET SOME GOODIES TO PLAY WITH''$ >;''A CUBE AROUND THE ORIGEN.''$ $ ;'' LETS HAVE A LOOK AT IT.'' > > > ;''ROTATE THE CUBE 30 DEGREES ABOUT Y AND 45 DEGREES ABOUT X, THEN MOVE TO THE CENTER OF THE SCREEN''$ EXAMPLE 4 ) (T .8PI) (DT ) (SF )) > > <* .SF .T > <- 10000 <* 20 .SF .T>> >> > 0> )> >>$ >;''TRY IT YOU'LL LIKE IT''$ " " PARAG 4-8 THIS FUNCTION WILL PRODUCE A PARAMETRIC PLOT OF TWO FUNCTIONS. TL IS THE LOWWER LIMIT OF THE THE PARAMETER, AND TH IS THE HIGH LIMIT. FOO AND BAR ARE THE ATOMS WHO ARE THE NAMES TWO FUNCTIONS TO BE PLOTED. THE REST OF THE ARGS. ARE OPTIONAL. P IS THE NUMBER OF POINTS TO BE PLOTED. MODE CONTROLS THE SCAL ING, IF .MODE =''SAS'' (THE DEFALT) PARAG WILL SCALE ONE AXIS TO THE MAXIMUM SIZE ON THE SCREEN. IF .MODE=''DAS'' PARAG WILL SCALE BOTH X AND Y TO FULL SCREEN. THIS HOWEVER, DOESNT PRESERV ANGLES. IF .MODE ''NAS'' PARAG DOESNT DO ANY AUTOSCALING, YOU YOU HAVE TO. SCL IS A TWO ELEMENT LIST WITH THE X AND Y SCALES IN IT. XYDIDIS IS A TWO ELEMENT LIST WITH THE X AND Y DISPLACEMENTS IN IT. EX. $ ")>
