I left the second list unfinished on purpose. General Computing on GPU (OpenCL, CUDA, Compute shaders).Cooperating with the driver: locks, minimizing memory transfers, batching.Advanced memory management with buffers.Shaders (Geometry, Tessellation, Compute).3D Math - matrices, vectors, projections.Platform differences (PC vs Mobile vs Web vs Console).General knowledge about the computer graphics.I suggest the following topics for the beginning: OpenGL 4.5 (August 2014) can be compared to DX 11.1 or even supersede it. Tesselation shaders, draw indirect, ES2 compatibility, program binaries, separate shaders objects, Compute shaders. To illustrate this idea, I prepared two images: It can transform vertices, calculate color of fragments, delete or add more triangles and even more. Shader is a little program that can compute various things and is run on the GPU. There is a general form of the pipeline, but a lot of parts are fully controlled by you - thanks to shaders. Programmable pipeline is more like a white, transparent box where not only you put input data and wait for the result, but you can insert/change internal mechanisms as well. You could of course tweak this box to your needs but at some point, it was not enough. You inserted the vertex data in the front (at the input) and you got triangles written to the framebuffer (screen) at the end. What is the difference? This is quite a broad topic, but for now I think it is good to know that fixed pipeline was like a black box. Is there 'old OpenGL ' as well?īasically modern means "using programmable graphics pipeline", old means "fixed pipeline". The first question I would like to answer is why there is a term called 'modern OpenGL'. In this article, I will try to answer some of the questions above and create a guide to a wonderful world of graphics programming using OpenGL. Great! But what does it really mean and what options are available? Do you have to buy expensive books about this technology, or maybe some basic online tutorials are enough?

While GMA performance has been widely criticized in the past as being too slow for computer games, the latest GMA generation should ease many of those concerns for the casual gamer.ĭespite similarities, Intel's main series of GMA Integrated Graphics Processors (IGPs) is not based on the PowerVR technology Intel licensed from Imagination Technologies.Shaders + Cube Env Map + Phong Lighting Introduction Many of the advantages of the new GMA architecture come from the ability to flexibly switch as needed between executing graphics-related tasks or video-related tasks. The 4th generation of GMA combines fixed function capabilities with a threaded array of programmable executions units, providing advantages to both graphics and video performance. However, with the introduction of Intel's 4th generation of GMA architecture ( GMA X3000) in 2006, many of the functions are now built into the hardware, providing an increase in performance. The original architecture of GMA systems supported only a few functions in hardware, and relied on the host CPU to handle at least some of the graphics pipeline, further decreasing performance. Later, Intel integrated the i740 core into the Intel 810 chipset. The GMA line of GPUs replaces the earlier Intel Extreme Graphics, and the Intel740 line, the latter of which was a discrete unit in the form of AGP and PCI cards with technology that evolved from companies Real3D and Lockheed Martin.
