# siconos\_vview(1)

Viewer for Siconos mechanics-IO HDF5 files based on VTK.

## NAME

siconos\_vview - Viewer for Siconos mechanics-IO HDF5 files based on VTK.

## SYNOPSIS

**siconos\_vview** \[*OPTION*\]... *\<HDF5\>*

## DESCRIPTION

Description: Viewer and exporter for Siconos mechanics-IO HDF5 files based on VTK.

## OPTIONS

**--help**

-

  display this message

**--version**

-

  display version information

**--tmin=** value

-

  set the time lower bound for visualization

**--tmax=** value

-

  set the time upper bound for visualization

- **--cf-scale=** value

  (default : 1.0 )

-

  rescale the arrow representing the contact forces by the value. the normal cone and the contact points are also rescaled

**--no-cf**

-

  do not display contact forces

**--imr**

-

  immediate-mode-rendering, use less memory at the price of slower rendering

**--global-filter** (default : off)

-

  With export mode, concatenates all blocks in a big vtkPolyData. This option is for when the number of objects is huge. With vview, the display is done with only one vtk actor. Note that global-filter use a vtkCompositeDataGeometryFilter which is slow.

**--no-depth-peeling** (default : on)

-

  do not use vtk depth peeling

**--maximum-number-of-peels=** value

-

  maximum number of peels when depth peeling is on

**--occlusion-ratio=** value

-

  occlusion-ratio when depth peeling is on

- **--normalcone-ratio** = value

  (default : 1.0 )

-

  introduce a ratio between the representation of the contact forces arrows the normal cone and the contact points. useful when the contact forces are small with respect to the characteristic dimesion

**--advance=** value or 'fps'

-

  automatically advance time during recording (default : don't advance)

**--fps=** value

-

  frames per second of generated video (default 25)

**--camera**=*x*,y,z

-

  initial position of the camera (default=above looking down)

**--lookat**=*x*,y,z

-

  initial direction to look (default=center of bounding box)

**--up**=*x*,y,z

-

  initial up direction of the camera (default=y-axis)

**--ortho**=*scale*

-

  start in ortho mode with given parallel scale (default=perspective)

**--with-charts**=*value*

-

  display convergence charts

**--visible**=*all*

-

  all: view all contactors and avatars avatars: view only avatar if an avatar is defined (for each object) contactors: ignore avatars, view only contactors where avatars are contactors with collision\_group=-1

**--with-edges**

-

  add edges in the rendering (experimental for primitives)

**--with-fixed-color**

-

  use fixed color defined in the config file

**--depth-2d=**\<value\>

-

  specify a depth for 2D objects

**--verbose=**\<int verbose\_level\>
