osg.Uniform

class osg.Uniform
Represents:c++ class
Wraps:osg::Uniform
Bases:osg.Object

osg.Uniform encapsulates glUniform (https://www.khronos.org/registry/OpenGL-Refpages/es2.0/xhtml/glUniform.xml) values. For convenience and visibility in Lua there are a number of setters and getters kind of set<VaueType><Dimension> and get<VaueType><Dimension> (e.g. osg.Uniform.setInt2() and osg.Uniform.getInt2()) for setting and geting values of corressponding osg.Uniform object. Static functions for creating an osg.Uniform of specified type are also provided and has signature osg.Uniform.<ValueType><Dimension> (e.g. osg.Uniform.Vec2d()).
