simpleGLES_EGLOutput - Simple OpenGLES EGLOutput

Description

Demonstrates data exchange between CUDA and OpenGL ES (aka Graphics interop). The program modifies vertex positions with CUDA and uses OpenGL ES to render the geometry, and shows how to render directly to the display using the EGLOutput mechanism and the DRM library.

NOTE: On Orin platform, execute this command before running sample:
$ sudo modprobe nvidia-drm modeset=1
