  \class SoSFMatrix SoSFMatrix.h Inventor/fields/SoSFMatrix.h
  \brief The SoSFMatrix class is a container for an SbMatrix.
  \ingroup fields

  This field is used where nodes, engines or other field containers
  needs to store a 4x4 matrix.

  Fields of this type stores their value to file as a set of 16
  floating point values, written from the matrix in row-major mode.

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
