glUniformBlockBinding â assign a binding point to an active uniform block
C Specificationvoid glUniformBlockBinding( GLuint program, Â GLuint uniformBlockIndex, Â GLuint uniformBlockBinding);
Â
Parametersprogram
The name of a program object containing the active uniform block whose binding to assign.
uniformBlockIndex
The index of the active uniform block within program whose binding to assign.
uniformBlockBinding
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 the past.
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 to zero.
ErrorsGL_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_MAX_UNIFORM_BUFFER_BINDINGS.
GL_INVALID_VALUE is generated if program is not the name of a program object generated by the GL.
