Abstract
One embodiment of the invention is a method of accessing a bindable uniform variable bound to a buffer object that includes the steps of creating a linked program object comprising one or more shader programs, where each shader program includes instructions written in a high-level shader language, and where the linked program object includes a reference to a bindable uniform variable and indicates which shader programs use the bindable uniform variable. The method also includes determining a memory size to support the bindable uniform variable, allocating a buffer object having the memory size, binding the buffer object to the bindable uniform variable, populating the buffer object with values for the bindable uniform variable, and accessing the values of the bindable uniform with one or more of the shader programs in the linked program object.
