OpenGL

Open Graphics Library (OpenGL) is the most widely adopted 2D and 3D graphics API in the industry, cross-platform. Silicon Graphics Inc. began developing OpenGL in 1991 and released it on June 30, 1992. Now, it is a technology maintained by the Khronos Group.

Evergine uses the OpenGL graphics API on the Web platform and Windows desktop but is deprecating this technology in favor of Vulkan, the new modern graphics API created by the Khronos Group.

OpenGL is used on the Web platform by Evergine through a version named WebGL, which is the default version supported in the most popular browsers.

• Chrome, Edge, and Firefox support WebGL 2.0.
• Safari supports WebGL 1.0.

Supported OpenGL devices

• Windows 8/10/11 x64/x86 desktop
• Web Browsers on desktop, tablet, and mobile devices.

Checking OpenGL version

If you are running Windows 7 or later, the OpenGL library has already been installed on your system.

To check the OpenGL version available on your system, locate the control panel of your graphics card or download the OpenGL Hardware Capability Viewer.

Create a Graphics Context

To create a graphics context based on OpenGL, simply write:

GraphicsContext graphicsContext = new Evergine.OpenGL.GLGraphicsContext();
graphicsContext.CreateDevice();

To create a graphics context based on WebGL, simply write:

GraphicsContext graphicsContext = new Evergine.OpenGL.GLGraphicsContext(GraphicsBackend.WebGL2);
graphicsContext.CreateDevice();

Build & Run

You can select OpenGL API support during the new project creation from the Evergine launcher.

Desktop

If the project already exists, you can add OpenGL support from Evergine Studio by clicking on Settings -> Project Settings.

Select and add the profile for Windows (OpenGL).

You can run on OpenGL by clicking on File -> Build & Run -> Windows.OpenGL.

WebGL

To support Web platforms based on WebGL versions, you also need to add the WebGL Template from the project settings, selecting WebGL 2.0 or 1.0 depending on your project needs.
