[Qwt3d]Animated plot

Hello,

Any know if there is an easy way to draw a 3d animated plot, to visualize that kind of function :
z = f(x, y, t)

Thanks in advance

Finally I tried something but it didn't work :

Code:

---

from PyQt4.Qwt3D.ezplot import SurfacePlot
from PyQt4.Qwt3D import Function
from PyQt4 import Qwt3D, QtCore
 
from PyQt4.QtCore import QTimer, QObject
 
 
 
class MyFunc(Function):
	def __init__(self, pw):
		super(MyFunc, self).__init__(pw)
		self.pw = pw
		self.t = 0
		self.deltaT = 100
		self.timer = QTimer()
		qtObject = QObject()
		qtObject.connect(self.timer, QtCore.SIGNAL("timeout()"), self.updatePW)
		self.timer.start(self.deltaT)
 
	def __call__(self, x, y):
		print "__call__"
		return 3 + 4*x**2 - 5*y**2 + self.t
 
	def updatePW(self):
		self.debugCalled = True
		self.t += self.deltaT/1000
		#self.pw.calcNormals()
		#self.pw.calculateHull()
		#self.pw.createPoints()
		#self.pw.createData()
		#self.pw.updateNormals()
		#self.pw.updateData()
		#self.pw.updateGL()
		#self.pw.update()
 
class Plot(SurfacePlot):
	def __init__(self):
		super(Plot, self).__init__()
		self.myFunc = MyFunc(self)
		self.myFunc.setMesh(41,31)
		self.myFunc.setDomain(-1.73, 1.5, -1.5, 1.5)
		self.myFunc.setMinZ(-10)
 
		self.myFunc.create()
 
		self.setRotation(30, 0, 15)
		self.setScale(1, 1, 1)
		self.setShift(0.15, 0, 0)
		self.setZoom(0.9)
 
		for i in xrange(self.coordinates().axes.size()):
			self.coordinates().axes[i].setMajors(7)
			self.coordinates().axes[i].setMinors(3)
		self.coordinates().axes[Qwt3D.X1].setLabelString("x-axis")
		self.coordinates().axes[Qwt3D.Y1].setLabelString("y-axis")
		self.coordinates().axes[Qwt3D.Z1].setLabelString("z-axis")
 
		self.setCoordinateStyle(Qwt3D.BOX)
 
		#self.updateData()
		#self.updateGL()
 
 
if __name__ == "__main__":
	from PyQt4.QtGui import QApplication
	import sys
	app = QApplication(sys.argv)
	plot = Plot()
	plot.resize(800,600)
	plot.show()
	sys.exit(app.exec_())

Every time my funtion updatePW is called, I would like to recalculate the graph data, but I don't know how I could do that, I tried a bound of functions.
Anyone has an idea ?

Thanks in advance

maybe you should take a look into the qwt3d forum at sourceforge. the qwt we are talking about here has nothing to do with qwt3d...
