[Therion] Altitude metapost error -2

Strange and interesting.

I can replicate this with Therion 6.4.0

How did you deduce that 0.1 degree inclination change should bypass the problem?

Hello

I have error, when using command «color map-fg altitude».

If i had commented survey in Berloga.th  —  « v78 v79 4.61 172.9 -41.7» or changed vert angle to -41.8, then all compiling ok.

 

Log of error:

 

>> d

! Unknown relation will be considered false.

                   :

log->begingroup(if(EXPR2)=0:

                            0else:mlog((EXPR2))/mlog(10)fi)endgroup

<to be read again> 

                   ;

s_altitudebar->...d:=(EXPR1)-(EXPR0);dlog:=log(d);

                                                  if.dlog.mod1<0.301:dv:=2;e...

                                                  ;

Oh dear. I can't decide if the expression above is positive,

negative, or zero. So this comparison test won't be `true'.
