The following diagram shows an illustration of vertical parallelism (processing in stages represented by boxes) and horizontal parallelism (multiple processing units for each stage represented by multiple arrows between boxes).Į.g. In the context of GPUs, horizontal parallelism of the graphics pipeline was an important feature to achieve the performance of modern GPUs. Again, the concept was also employed at Ford Motor Company and in many other industries. This allows for even more parallelism than the vertical parallelism in a single pipeline. Horizontal parallelism describes the possibility to process work in multiple pipelines.In the context of processing units in GPUs, the simple tasks correspond to less complex processing units, which save costs and power consumption.Īssembly plant of the Bell Aircraft Corporation with multiple parallel assembly lines, ca. This made mass production (and therefore mass consumption) possible. This concept was also crucial in the development of the assembly line at Ford Motor Company: many workers can work in parallel on rather simple tasks. Vertical parallelism describes parallel processing at different stages of a pipeline.In fact, they implement two kinds of parallelism: vertical and horizontal parallelism: This is the main reason for their performance.

Therefore, the OpenGL ES 2.0 pipeline is not only highly relevant for programmers of mobile graphics using OpenGL ES 2.0 and web-based 3D graphics using WebGL, but also a very good starting point to learn about desktop-based 3D graphics using OpenGL, including 3D graphics in game engines such as Blender, Unity and Torque 3D. It is also very similar to the OpenGL 2.0 pipeline without many of the features that were deprecated in newer versions of OpenGL. The OpenGL ES 2.0 pipeline is important for GLSL shaders in OpenGL ES 2.0 and WebGL. 2 Programmable and Fixed-Function Stages.
