Since the layout of the data within a uniform buffer object is implementation dependent, it required us to query for the variable offsets. However, one can avoid this by asking OpenGL to use the standard layout std140. This is accomplished by using a layout qualifier when declaring the uniform block. day trading with pivot points \u0026 price action

The "single uniform" is allowed to be a struct, array, or array of structs rather than just a single basic type. So one could store multiple component members easily enough. This extension only provides storage for this uniform; it does not expose layout.
