3D rendering, scatterpoints disapear near edges of surfaces #5756
Description
Hi
Environment:
Linux
python 2.7.8
matplotlib 1.5.0 (installed via pip 2015-12-29)
When plotting scattered points in combination with surfaces in 3D points disapear when viewed at an angle that renders them close to the edges of the surface along the line of sight. The code below reproduces the problem. (If the resulting figure is rotated a few degrees the scatter point will be made visible).
#! /usr/bin/env python
import matplotlib
matplotlib.use('tKAgg')
import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D
from mpl_toolkits.mplot3d.art3d import Poly3DCollection
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
ax.scatter((0.5,), (0,), (0,))
poly = Poly3DCollection([zip((0,0,0,0,0),(1,1,-1,-1,1),(1,-1,-1,1,1))])
poly.set_facecolor((1,0,0,1))
ax.add_collection3d(poly)
ax.set_xlim3d([0,1])
ax.set_ylim3d([-1,1])
ax.set_zlim3d([-1,1])
ax.view_init(elev=-165,azim=-140)
plt.show()
