It says that the data file needs to be delimited by commas. It doesn't
explain the details of the unpredictable results that you will get if
you try to use space and end-of-line as delimiters.
In this particular case, the input is
20
"Tile0001" 64 61 78 8 0 4 -29 0 0.8 -28.7 0.9 -28.1 0.8 -27 9 0.0 -28.0 0.0 -28.7 0.2
-29.0 0.4 -29.0
"Tile0002",55,52,66,5,1.7,-29.0,1.9,-28.7,1.2,-28.3,1.0,-29.0,1.7,-29.0
but the POV command #read(window,tilenumber,rrr,ggg,bbb,points) returns
the following on the first pass:-
tilenumber = 64
rrr = 78
ggg = 0
bbb = -29
points = 0.8
This is not what anyone wants and you probably should not depend on POV
behaving in a predictable manner when supplied with data that is not
separated by commas.
If you want a series of characters that contain spaces and/or end-of-
line characters to be considered as a single field, then you should
enclose it in quotes and it will be read as a string (you can't get it
to read it as a number because numbers can't contain such characters).
Your code needs to look more like this:-
#fopen window "balcony.csv" read
#read(window,tile_amount)
#declare tilearray=array[tile_amount][21]
#declare current_tile=0;
#while(defined(window))
#read(window,tilenumber,rrr,ggg,bbb,points)
//#declare tilearray[current_tile][0]=tilenumber; Note 1
#declare tilearray[current_tile][1]=rrr;
#declare tilearray[current_tile][2]=ggg;
#declare tilearray[current_tile][3]=bbb;
#declare tilearray[current_tile][4]=points;
#declare n=0;
#while(n<points)
#read(window,pointx,pointy)
#declare tilearray[current_tile][5+n]=pointx;
#declare tilearray[current_tile][6+n]=pointy;
#declare n=n+1; // Note 2
#end
#declare current_tile=current_tile+1;
#end
#fclose window
Note 1: You can't do that with a string.
Note 2: You had n=n+2, which only reads half the points.
Your data should use only commas as delimiters, like this.
Note, in particular, that commas are needed at the ends of lines.
