title: Controlling alpha value on 3D scatter plot using Python and matplotlib
body: <p>I'm plotting a 3D scatter plot using the function scatter and mplot3d. I'm choosing a single color for all points in the plot, but when drawn by matplotlib the transparency of the points is set relative to the distance from the camera. Is there any way to disable this feature? </p>
  
  <p>I've tried setting the alpha kwarg to None/1 and also set vmin/vmax to 1 (in an attempt to force the color scaling to be a solid single color) with no luck. I didn't see any other likely options related to this setting in the scatter documentation. </p>
  
  <p>Thanks!</p>
