Detailed Description

This represents a manipulable handle in the 3D view only. It represents an object the user can interact with using
the mouse rather than the indicator for a manipulable object in another view.

Constructor & Destructor Documentation

__init__()

Member Function Documentation

checkMeshIntersect()

def checkMeshIntersect	(		self,
			ray,
			nodes,
			tris
	)

Returns the (index,result) pair if `ray' intersects `tris' through the triangle at that index with `node's as
the list of vertices. Returns (-1,None) if no intersect.

Here is the caller graph for this function:

getCameraDirection()

def getCameraDirection

(

self

)

Get the direction vector of the camera selecting this handle, or +Z if not selected.

Here is the call graph for this function:

getCameraRay()

def getCameraRay	(		self,
			x = None,
			y = None
	)

Get the ray originating from the previous mouse position, or (x,y) if provided, on the camera selecting this
handle. If not selected, None is returned.

getDragDistance()

def getDragDistance	(		self,
			axis,
			dragvec,
			startpos,
			isPerpendicular = False
	)

Calculates the distance a mouse drag represents in relation to a given axis. The drag is represented by the
position delta `dragvec', ie. vec3(b.x()-a.x(),b.y()-a.y(),0) if the mouse was dragged from screen position a to b.
The argument `startpos' is where the attached object was when the button was first pressed.
The returned value is proportional to how parallel (or perpendiculat if `isPerpendicular' is true) to the screen
axis the drag is: in the direction of `axis' yields values up to 1, directly away from yields values down to -1.

isSelected()

def isSelected

(

self

)

mouseMove()

def mouseMove	(		self,
			e
	)

Called when the handle is dragged, sets previous position and calls self.mouseDrag().

Here is the call graph for this function:

mousePress()

def mousePress	(		self,
			camera,
			e
	)

Called when the handle is clicked, sets previous position, self.buttons, and self.pressedCamera.

Here is the call graph for this function:

Here is the caller graph for this function:

mouseRelease()

def mouseRelease	(		self,
			e
	)

Called when handle is released, clears all state values.

Here is the caller graph for this function:

setPosition()

def setPosition	(		self,
			pos
	)

Set the position of each internal figure to `pos'.

Here is the caller graph for this function:

setRotation()

def setRotation	(		self,
			yaw,
			pitch,
			roll
	)

Set the rotation of each internal figure to rotator(yaw,pitch,roll).

Here is the caller graph for this function:

setScale()

def setScale	(		self,
			scale
	)

Set the scale of each internal figure to `scale'.

Here is the caller graph for this function:
