For several years now Apple has been pushing for the OpenGL/OpenCL deprecation in their software ecosystem to instead emphasize their in-house Metal API. With the forthcoming macOS 11.0 'Big Sur', the OpenGL support will ultimately be either in a poor state or outright removed. Given Apple's been phasing out support for OpenGL (and OpenCL), Zink on macOS holds merit - arguably even more so than Linux where there still is great OpenGL drivers available for all major hardware. Beyond reaching OpenGL 4.6 support in yet-to-be-merged patches and passing ~97% of the Piglit OpenGL tests and increasingly good performance compared to Intel's OpenGL driver, the latest interesting milestone is seeing initial work on bringing Zink to macOS. Set position of OpenGL window upper-left corner.The Zink Gallium3D driver that implements OpenGL on top of Vulkan has been on quite a roll recently. GlutInitDisplayMode(GLUT_SINGLE | GLUT_RGB) Set display mode as single-buffered and RGB color. registers callback routines and begins processing. Main routine: defines window properties, creates window,

Void keyInput(unsigned char key, int x, int y) Clear current modelview matrix to identity. Specify the orthographic (or perpendicular) projection, Clear current projection matrix to identity.

GlViewport(0, 0, (GLsizei)w, (GLsizei)h) Set viewport size to be entire OpenGL window. Flush created objects to the screen, i.e., force rendering. Draw a polygon with specified vertices. Stripped down OpenGL program that draws a square. As of now I am not able to run that C++ code I'm guessing because I have not downloaded GLEW or/and have not configured all the settings to work with that. I am also including the sample code that's in the textbook. What are some ways to have my computer graphics code with C++ work on my Mac.

The instructions to get C++ working with OpenGL are below. Hello I am trying to install GLEW on my Mac operating system for my computer graphics course.
