  \class SoMFColorRGBA SoMFColorRGBA.h Inventor/fields/SoMFColorRGBA.h
  \brief The SoMFColorRGBA class is a container for SbColor4f values.
  \ingroup fields

  This field is used where nodes, engines or other field containers
  needs to store multiple color values (i.e. "Red Green Blue"
  triplets).

  This field supports application data sharing through a
  setValuesPointer() method. See SoMField documentation for
  information on how to use this function.

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.
