Hello everybody,

i´d like to draw a PolygonObject in Xray mode into the viewport. Im able to draw the object, but just without xray.

def Draw(self, op, drawpass, bd, bh) :  
  if drawpass!=c4d.DRAWPASS_XRAY:  
      obj = MachCube(100, 75, 50)  
      bd.DrawPolygonObject(bh, obj, c4d.DRAWOBJECT_0)  
  return c4d.DRAWRESULT_OK  
def MachCube(size_x, size_y, size_z) :  
  size = c4d.Vector()  
  size.x = size_x  
  size.y = size_y  
  size.z = size_z  
  cube = c4d.PolygonObject(8, 6)  
  pnts = [c4d.Vector() for x in xrange(8)]  
  pnts[0] = c4d.Vector(-size.x/2, -size.y/2, -size.z/2)  
  pnts[1] = c4d.Vector(-size.x/2,  size.y/2, -size.z/2)  
  pnts[2] = c4d.Vector( size.x/2, -size.y/2, -size.z/2)  
  pnts[3] = c4d.Vector( size.x/2,  size.y/2, -size.z/2)  
  pnts[4] = c4d.Vector( size.x/2, -size.y/2,  size.z/2)  
  pnts[5] = c4d.Vector( size.x/2,  size.y/2,  size.z/2)  
  pnts[6] = c4d.Vector(-size.x/2, -size.y/2,  size.z/2)  
  pnts[7] = c4d.Vector(-size.x/2,  size.y/2,  size.z/2)  
  plys = c4d.CPolygon(0,1,3,2), c4d.CPolygon(2,3,5,4), c4d.CPolygon(4,5,7,6), c4d.CPolygon(6,7,1,0), c4d.CPolygon(1,7,5,3), c4d.CPolygon(6,0,2,4)  
  for index, ply in enumerate(plys) : cube.SetPolygon(index, ply)  
  return cube  

Is it possible to do?

It seems to work fine using DrawObject() and setting the ID_BASEOBJECT_XRAY parameter of the drawn object.

def Draw(self, op, drawpass, bd, bh) :  
 self._cube[c4d.ID_BASEOBJECT_XRAY] = op[c4d.ID_BASEOBJECT_XRAY]  
 bd.DrawObject(bh, self._cube, c4d.DRAWOBJECT_0, drawpass, op)  
 return c4d.DRAWRESULT_OK  

Also it seems to be the best solution to store the geometry as a member of your class.

Best wishes,

Hey Sebastian,

thx alot. I also tried to set the ID_BASEOBJECT_XRAY parameter yesterday. But I didnt try to let the object be a member. Thats the solution.

if drawpass!=c4d.DRAWPASS_XRAY:  
  self.cube[c4d.ID_BASEOBJECT_XRAY] = op[c4d.ID_BASEOBJECT_XRAY]  
  bd.DrawObject(bh, self.cube, c4d.DRAWOBJECT_0, drawpass, op)  

One other question just for knowing. Why cant I draw a primitive object like c4d.BaseObject(c4d.Ocube)? At this point its not importaint to know, but it was noticed by me.

Thx and greetings
