Announcement (4/26/2024):
Due to a number of requests, the deadline of HW3 has been extended
to Monday 4/29 at 11:59pm. HW4 will still be posted today (due on
Tues. 5/14 at 6pm) so that you can start working on HW4 as originally
scheduled.

Compilation and Installation Instructions for OpenGL on Windows
OpenGL Compilation on Mac OS or Linux (written by a former TA Zebin Xu):
"OpenGL Compilation on Mac OS or Linux using CMake" (Instructions)
Handout: example.cpp ("Example.tar.gz") ---
Example Program for Basic OpenGL Program Structure
Note:
After you un-zip and un-tar the file, there are two files:
"example.cpp" and "CMakeLists.txt". On Windows you only need
"example.cpp". On Mac OS or Linux you need both --- put them in the
same directory; see "OpenGL
Compilation on Mac OS or Linux using CMake" Sections 1-4 for more
details.
Handout: rotate-cube-new.cpp
("Rotate-Cube-New.tar.gz") ---
Sample Program for Shader-Based OpenGL, for OpenGL version 3.1 and
later
Instructions:
After you un-zip and un-tar the file, there are
1. source files, including C/C++ (*.cpp) and header (*.h) files
(to be used for all platforms), and a
file "CMakeLists.txt" (to be used for Mac OS or Linux), and
2. two shader files (*.glsl), to be used for all platforms.
Note:
To compile and run ---
For Windows put all files in the same directory/folder.
For Mac OS and Linux, see
"OpenGL Compilation on Mac OS or Linux using CMake" Section 5
Notes ("Reading shader files", p.6-8) for more details. In particular,
on p.7 there are figures showing the directory hierarchy clearly.
(If you get the error message "Failed to read vshader42.glsl", it
means that your OpenGL program is not able to find the vertex shader
file "vshader42.glsl" to read. See "InitShader.cpp" line 58. It is
nothing related to the GLSL version number. It is related to where you
put the shaders.)
Handout: rotate-cube-shading.cpp
("Rotate-Cube-Shading.tar.gz") ---
Sample Program for Shading and Lighting using Shader-Based OpenGL, for
OpenGL version 3.1 and later
Instructions:
Same as above.
Handout: checker-new.cpp
("Checker-New.tar.gz") ---
Sample Program of Texture Mapping using Shader-Based OpenGL, for
OpenGL version 3.1 and later
Instructions:
Same as above.
