Matrix generates no points while on vertex mode using a spline generator plugin

  • hey,

    i got a spline tool which is unsing the ISSPLINE and GENERATOR flag.

    if i set a matrix object mode to anything exept vertex it generates points accordingly to the choosen distribution mode.

    if i convert the spline generator to an actual spline the vertex distribution works well.

  • Hi Pyr,

    I've tried with a very basic spline generator and the clones are properly created under all "distribution" modes.

    Here's the plugin responsible for generating the curve:

    import math
    import c4d
    from c4d import plugins, utils
    PLUGIN_ID = 99911332
    class SDKSupport_11332 (plugins.ObjectData):
    	def Init(self, node):
    		return True
    	def GetContour(self, op, doc, lod, bt):
    		rad = 200
    		sub = 3
    		TANG = 0.415
    		op = c4d.SplineObject(sub, c4d.SPLINETYPE_BEZIER)
    		if not op: return None
    		for i in xrange(sub):
    			sn, cs = utils.SinCos(math.pi*i/float(sub-1))
    			op.SetPoint(i, c4d.Vector(cs*rad,sn*rad,0.0))
    			vl = c4d.Vector(sn*rad*TANG,-cs*rad*TANG,0.0)
    			vr = -vl
    			op.SetTangent(i, vl, vr)
    		return op
    if __name__ == "__main__":

    Can you provide some further detail on your spline generator?

    Cheers, Riccardo

  • Ok this was defently my fault. It works now.
    I was using GetVirtualObjects instead of GetContour.
