# Blurring
# ========

# This example shows how you can use `add_blurring` to blur a plot, or use
# `enable_depth_of_field`
# to highlight part of your plot.
import pyvista as pv

# Create several spheres
# ======================

# We use a uniform grid here simply to create equidistantly spaced points for
# our glyph filter
grid = pv.ImageData(dimensions=(4, 4, 4), spacing=(1, 1, 1))

spheres = grid.glyph(geom=pv.Sphere(), scale=False, orient=False)

# Blur the plot
# =============

# Add a few blur passes to blur the plot
pl = pv.Plotter()
pl.add_mesh(spheres, smooth_shading=True, show_edges=True)
pl.add_blurring()
pl.add_blurring()
pl.add_blurring()
pl.camera.zoom(1.5)
pl.enable_anti_aliasing('ssaa')
pl.show()

# Note how this is different than selectively blurring part of the mesh behind
# the focal plane
pl = pv.Plotter()
pl.add_mesh(spheres, smooth_shading=True, show_edges=True)
pl.enable_depth_of_field()
pl.camera.zoom(1.5)
pl.enable_anti_aliasing('ssaa')
pl.show()
