bind a buffer object to an indexed buffer target
Specify the target of the bind operation. target must be one of GL_ATOMIC_COUNTER_BUFFER , GL_TRANSFORM_FEEDBACK_BUFFER , GL_UNIFORM_BUFFER or GL_SHADER_STORAGE_BUFFER .
Specify the index of the binding point within the array specified by target .
The name of a buffer object to bind to the specified binding point.
glBindBufferBase binds the buffer object buffer to the binding point at index index of the array of targets specified by target . Each target represents an indexed array of buffer binding points, as well as a single general binding point that can be used by other buffer manipulation functions such as glBindBuffer or glMapBuffer . In addition to binding buffer to the indexed buffer binding target, glBindBufferBase also binds buffer to the generic buffer binding point specified by target .
Calling glBindBufferBase is equivalent to calling glBindBufferRange with offset zero and size equal to the size of the buffer.
The GL_ATOMIC_COUNTER_BUFER target is available only if the GL version is 4.2 or greater.
The GL_SHADER_STORAGE_BUFFER target is available only if the GL version is 4.3 or greater.
GL_INVALID_ENUM is generated if target is not GL_ATOMIC_COUNTER_BUFFER , GL_TRANSFORM_FEEDBACK_BUFFER , GL_UNIFORM_BUFFER or GL_SHADER_STORAGE_BUFFER .
GL_INVALID_VALUE is generated if index is greater than or equal to the number of target -specific indexed binding points.
GL_INVALID_VALUE is generated if buffer does not have an associated data store, or if the size of that store is zero.
