Make sure you have cmake and vcpkg installed. Detailed instructions can be found here.
Navigate to the vcpkg directory, and installed the following packages via vcpkg,
vcpkg install glfw3 glad glm assimp
Navigate to the root directory glad_framework, and type in
cmake -B "build" -S . -DCMAKE_TOOLCHAIN_FILE=[path to vcpkg]/scripts/buildsystems/vcpkg.cmake
cmake --build build
Installing on Linux is roughly the same, with a few dependencies to be installed via the system package manager. On Debian and Ubuntu, those packages can be installed with apt-get install libxinerama-dev libxcursor-dev libgl1-mesa-dev xorg-dev.
Also, you must first make sure you have CMake, Git, and GCC by typing as root (sudo) apt-get install g++ cmake git.
With those packages installed, follow the instructions on https://vcpkg.io/en/getting-started.html to install vcpkg, then use vcpkg to install the packages. Best to do it with sudo to suppress possible errors.
vcpkg install glfw3 glad glm assimp
Next, navigate root directory glad_framework, and config the project with
cmake -B "build" -S . -DCMAKE_TOOLCHAIN_FILE=[path to vcpkg]/scripts/buildsystems/vcpkg.cmake.
and build it with cmake --build build.
Building on Mac OS X is fairly simple:
brew install cmake assimp glm glfw freetype
cmake -S . -B build
cmake --build build -j$(sysctl -n hw.logicalcpu)
Depending on your build system, the executable directory can differ. Make sure you have all the binaries copied directly under glad_framework\src (with assets\ and shaders\ in it).
The code is hugely based on the awesome online opengl tutorial, and you can refer to their website as documentation of specific code.
We've provided an example in main.cpp.
First, we load a bunny with
Model bunny("assets/bunny/bunny.obj");Then within the main while (!glfwWindowShouldClose(window)) loop, we set the model matrix in shaders and call Model.draw(Shader) to do the rendering.
depthShader.setMat4("model",glm::translate(glm::mat4(1.0f),glm::vec3(0.0f,0.0f,0.0f)));
bunny.Draw(depthShader);To modify the scene, you can add your code to the lambda expression renderScene;
The keyboard control function is defined in void processInput(GLFWwindow *window) in main.cpp. Currently, the keys w, a, s, d are occupied for moving and l, c are occupied by switching light/camera movement and switching on/off of the upper-right corner display.
