pfxstrokes([filename=string], [postCallback=boolean], [selected=boolean])
Note: Strings representing object names and
arguments must be separated by commas. This is not depicted in the
synopsis.
pfxstrokes is NOT undoable, NOT queryable, and
NOT editable.
This command will loop through all the Paint Effects strokes,
including pfxHair nodes, and write the current state of all the
tubes to a file. For normal stroke nodes tubes must be ON in the
brush or there will be no output. For pfxHair nodes there will
always be output, but the format is different than for stroke
nodes(however one can assign a brush with tubes = ON to a pfxHair
node, in which case it will output the same format as strokes). The
general file format is ASCII, using commas to separate numerical
values and newlines between blocks of data. The format used for
pfxHair nodes presents the hair curves points in order from root to
tip of the hair. The hairs follow sequentially in the following
fashion: NumCvs pointX,pointY,pointZ, normalX,normalY,normalZ,
width, colorR,colorG,colorB, paramU pointX,pointY,pointZ,
normalX,normalY,normalZ, width, colorR,colorG,colorB, paramU etc...
NumCvs pointX,pointY,pointZ, normalX,normalY,normalZ, width,
colorR,colorG,colorB, paramU etc.. The format used to output files
for brushes with tubes=ON is more complex. The tubes can branch and
the order the segments are written is the same order they are drawn
in. Slowly drawing a tall grass brush in the paint effects panel
can help to illustrate the order the segments will appear in the
file. New tubes can start "growing" before others are finished.
There is no line for "NumCvs". Instead all data for each segment
appears on each line. The data on each line is the same as passed
into the paint effects runtime function. See the argument list of
paintRuntimeFunc.mel for the order and a description of these
parameters. The parameters match up exactly in the order they
appear on a line of the output file with the order of arguments to
this function. If one wishes to parse the output file and connect
the segments together into curves the branchId, parentId and
siblingCnt parameters can help when sorting which segment connects
to which line. Using the -postCallback option will write out the
tubes data after it has been proessed by the runTime callback.
