EGL Specifications and Extensions

EGL is an interface between Khronos rendering APIs such as OpenGL ES and the underlying native platform window system. It handles graphics context management, surface/buffer binding, and rendering synchronization and enables high-performance, accelerated, mixed-mode, 2D and 3D rendering using other Khronos APIs.

EGL Specifications

This product supports the Khronos Native Platform Graphics Interface (EGL Version 1.5 - August 27, 2014)

EGL Extensions

There are some EGL extensions that are supported on the prececessor NVIDIA® Tegra® processors that are unsupported on this NVIDIA® Tegra® processor. For a list of those unsupported extensions and work-around advice, see the "OpenGL ES Porting Guide" topic in the "Graphics Guide" chapter in the Development Guide.

EGL Extensions

NVIDIA DRIVE™ product supports the Khronos Native Platform Graphics Interface (EGL 1.5 Specification). The OpenGL ES driver in this release supports the following EGL extensions.

Attention
Some NVIDIA DRIVE™ releases support a subset of the extensions documented here. To ensure your release supports a given extension, you must query the driver. For example, the following code snippet determines whether the driver supports the EGL_EXT_platform_wayland EGL extension:
// Create an EGL context before you call this function.
extensionString = (const char*)eglQueryString(EGL_NO_DISPLAY, EGL_EXTENSIONS);
if (strstr(extensionString,
    "EGL_EXT_platform_wayland")) {
    // The extension is available. Do something with it.
}
else {
    // The extension is not available.
    // Use a workaround that produces results that are similar
    // to the EGL extension.
}
