Features

The following lists are a selection of the features included in Inviwo. You can easily add more data types and visualization methods by creating your own module.

Data Import

Data can be loaded into Inviwo from the file formats below, or imported directly from python or GLSL scripts.

  • Volume Import
    .dat (internal), .raw,
    .pvm (used in the Volume Library)
    .nii NIfTI (commonly used for Neuroimaging, MRI and fMRI, data)
  • Image Import
    .bmp, .raw, .exr, .jpg, .png, etc (using the CImg Library)
  • Geometry Import with more than 40 different ones through the “Open Asset Import Library, i.e. Assimp
  • HDF5 for high volume and flexible data

Visualization methods

Inviwo provides many visualization methods for a range of data types such as triangular meshes, images, volumes, vector fields and multidimensional arrays.

Geometry
