Viper is a minimalistic scientific plotter and run-time visualization module. Viper has support for visualizing meshes and solutions in DOLFIN:

Examples

 from dolfin import *

 # Plot a mesh
 mesh = UnitCube(16, 16, 16)
 plot(mesh)

 # the following code is out of date!

 # 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")

Features

• 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
