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?
Means the support for higher versions could right now be higher than reported.Shaders + Cube Env Map + Phong Lighting Introduction Many people are reporting the lowest of the two numbers of the machines they have. Newer graphics cards have so much more computational power, it's ridiculous to use very old systems, 3D/content creation such as done with Blender is computationally intensive.
Performance wise, urging people to use modern equipment is a good thing.Īt some point you have to stop supporting old systems. Using higher OpenGL versions and using more features can always be added and changed later. OpenGL 4.x is still evolving, changing and some big api cleanups are happening with DSA now added in the OpenGL 4.5 release. OpenGL 3.3 seems to be a stable target to develop for. Thus the support for OpenGL 3.3 and up will be higher by the time this feature comes out. Implementing OpenGL support will take time. In the blenderartists poll, about 84.77% has OpenGL 3.3 or higher and this number will only go up. ( 4.3 or higher is supported by 67.17% ) The poll on Blenderartists is very informative to how OpenGL versions are present in users systems: Why not make two paths, a CPU render path and a GPU render path using OpenGL. With the wildly varying configurations and the need for fallbacks. The file will be in your list of Text files, named as system-info.txt, if the file is already generated, Blender will add a numeric suffix for the subsequent ones. To read the Text, switch to the Blender Text Editor Window, using the Window type Selector, and then, clicking on the button Browse Text to be Linked of the Text Editor, your text block will be shown in the Editor. You can also use Blender Search to generate the file. When you click on this Option, Blender will verify your installation, will change the Info Window for a while when generating the file ( See: Info Window – Info.txt ). The text lists various key properties of your system and Blender, which can be useful in diagnosing problems. System Info - Creates a system-info file, which you can access in the Blender Text Editor. You can check your supported OpenGL with this quick tip by pitiwazou.
IS OPENGL 4.4 STILL USED UPGRADE
As the Blender developers are considering to upgrade Blender to OpenGL 2.1, a community initiative on BlenderArtists is mapping OpenGL support.īlender is moving to a new OpenGL version in the future and developers want to know how many people will benefit and how many will not be able to use Blender no more! So Blender Artist as made a poll asking people about the OpenGL version.
