The Painter Interface provides all necessary functions for developing custom Paint Tools. The Interface .thePainterInterface drives all its callbacks through user-defined functions. You need to implement the following functions:
StartStroke
PaintStroke
EndStroke
CancelStroke
SystemEnd
These functions are callbacks in response to the paint system. They will be called as the users paints across a mesh.
To initialize these functions, you need to call thePainterInterface.ScriptFunctions method:
|
FOR EXAMPLE: |
fn startStroke = print "Handle start stroke here" fn paintStroke = print "Handle paint stroke here" fn endStroke = print "Handle end stroke here" fn cancelStroke = print "Handle cancel stroke here" fn systemEnd = print "Handle system end here" thePainterInterface.ScriptFunctions startStroke paintStroke endStroke cancelStroke systemEnd |
Once you have established the connection the thePainterInterface, you will need to tell it what to paint on. This is done by calling the initializeNodes method.
|
FOR EXAMPLE: |
nodeList = $ thePainterInterface.initializeNodes 0 nodeList |
|
Once you have set up the nodes, you need to tell the system when you want to start a paint session: |
thePainterInterface.startPaintSession() |
|
The Painter Interface will call your functions until you end the session. In order to finish painting, you should call |
thePainterInterface.endPaintSession() |
