SYNOPSISviper [OPTIONS]
DESCRIPTION
Viper is a minimalistic scientific plotter and run-time visualization
module. Some its the features includes:
* 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-h, --help
Display help text and exit.
-i file, --input file
Specify input file.
-o file, --output file
Specify output file.
-l lut file, --lut lut file
Specify lookup table (LUT) file.
-d data file, --data data file
Specify data file.
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")
