Text Rendering In OpenGL // OpenGL Tutorial #46.1

Описание: This is the first of two videos on font and text rendering in OpenGL using the FreetypeGL library. In this video we learn how to build FreetypeGL and its dependencies on Windows. In the next one we will integrate it into an OpenGL application.

🔥 See the list of the books that I'm using as background information for my tutorials: https://ogldev.org/books.html. I highly recommend them for learning more about OpenGL and Vulkan. These are affiliate links so if you use them to buy any of the books the price is the same for you and I will get a small commission (thank-you!).

Here's a short summary of the steps presented in the video:

1. Install CMake.
2. Create ‘work’ directory
3. Create ‘work\lib’
4. Download Freetype from https://download.savannah.gnu.org/rel... and extract it in 'work'.
5. Open solution from freetype\builds\windows\vc2010
6. Change to ‘Release’ build and build solution.
7. Copy freetype\objs\x64\Release\freetype.lib/dll to work\lib
8. Clone https://github.com/rougier/freetype-g...
9. Open freetype-gl\VisualC\freetype-gl.sln (using Visual Studio).
10. If asked, upgrade solution.
11. Change to ‘Release’ build
12. Add to C/C++ - General - Additional include directories:
C:\Users\emeir\Documents\work\freetype-2.13.0\include
ogldev\Include
13. Copy freetype-gl\VisualC\bin\Release_x64\freetype-gl.lib to work\Lib
14. Copy "C:\Program Files (x86)\Windows Kits\10\Lib\10.0.19041.0\um\x64\OpenGL32.Lib" to work\lib.

Create Freetype-GL demos
1. Download GLFW source package from https://github.com/glfw/glfw/releases...
2. Unzip the package, open terminal in the extract directory and execute:
cmake -G "Visual Studio 17 2022" -DCMAKE_BUILD_TYPE=Release -S . -B build
3. Open build/GLFW.sln and build in release build.
4. Execute in terminal:
cmake --install build --prefix install
5. cd freetype-gl/demo
6. Add to CMakeLists.txt:
list(APPEND CMAKE_PREFIX_PATH "../../glfw-3.3.8/install")
7. Open freetype-gl/demos/Project.sln
8. Add to demo-utils project include:
C:\Users\emeir\Documents\work\freetype-gl
ogldev\include
9. Remove include config.h from opengl.h
Add link directory to Ansi project: ..\..\Lib
Add "C:\Users\emeir\Documents\ogldev2\Windows\Lib\glew32.lib"
