Viper is a minimalistic scientific plotter and run-time visualization module. It 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in DOLFIN.Examples: from dolfin import * # Plot a mesh mesh = UnitCube(16, 16, 16) plot(mesh) # the following code is out of date!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\")Viper depends on VTK with Python support.Here are some key features of \"Viper\":
