* Light-weight and minimalistic
* Extended keybindings
* Interactive
* Save as png, VTK
* 2D and 3D
* Scalar, vector, and displacement fields
* Multiple input formats
* In PyCC mode; direct plotting of NumPy arrays over DOLFIN meshes
* Can be used as standalone plotting application, or used as part of
PyDOLFIN
OPTIONS

EXAMPLE
Viper has support for visualizing meshes and solutions in DOLFIN:
from dolfin import *
# Plot a mesh
mesh = UnitCube(16, 16, 16)
plot(mesh)
# Plot a scalar function
u = Function("poisson.xml")
plot(u)
# Plot a vector function as a displacement field
d = Function("elasticity.xml")
plot(d, mode="displacement")
# Save as png
p = plot(mesh)
p.write_png("mesh.png")
# Save as VTK
p = plot(u)
p.write_vtk("poisson.vtk")
