glUniformBlockBinding - assign a binding point to an active uniform block
The name of a program object containing the active
uniform block whose binding to assign.
The index of the active uniform block within
program whose binding to assign.
Specifies the binding point to which to bind the uniform
block with index uniformBlockIndex within program.
Binding points for active uniform blocks are assigned using
glUniformBlockBinding. Each of a program's active uniform blocks has a
corresponding uniform buffer binding point. program is the name of a
program object for which the command glLinkProgram() has been issued in
If successful, glUniformBlockBinding specifies that
program will use the data store of the buffer object bound to the
binding point uniformBlockBinding to extract the values of the
uniforms in the uniform block identified by uniformBlockIndex.
When a program object is linked or re-linked, the uniform buffer
object binding point assigned to each of its active uniform blocks is reset
GL_INVALID_VALUE is generated if uniformBlockIndex is not an
active uniform block index of program.
GL_INVALID_VALUE is generated if uniformBlockBinding
is greater than or equal to the value of
GL_INVALID_VALUE is generated if program is not the
name of a program object generated by the GL.
glUniformBlockBinding is available only if the GL version is 3.1 or
glGetActiveUniformBlock() with argument GL_UNIFORM_BLOCK_BINDING
