Vender

Vender is an OpenGL rasterizer. Vender provides a modular architecture for scene setup, camera control, and rendering. It leverages modern C++ capabilities and provides a simple GUI using ImGui for real-time interaction.

This guide will walk you through the setup process for the vender OpenGL application using CMake and vcpkg for dependency management.

Prerequisites

• CMake (version 3.15 or newer)
• A C++ compiler with C++20 support
• OpenGL drivers installed on your system

Clone the Repository

Start by cloning the main project repository to your local machine:

git clone https://github.com/silvanias/Vender.git
cd vender

Set up vcpkg

Create a vcpkg directory inside the project and set up vcpkg, a C++ library manager:

mkdir vcpkg
cd vcpkg
git clone https://github.com/microsoft/vcpkg.git
./vcpkg/bootstrap-vcpkg.sh # On Windows use .\vcpkg\bootstrap-vcpkg.bat

Install the required libraries:

./vcpkg/vcpkg install glm
./vcpkg/vcpkg install glfw3
./vcpkg/vcpkg install glad

Again, on Windows, you would use .\vcpkg\vcpkg instead of ./vcpkg/vcpkg.

Clone Dear ImGui

Clone the Dear ImGui library inside the lib directory of your project:

mkdir lib
git clone https://github.com/ocornut/imgui.git lib/imgui

Configure CMake

Create a build directory and navigate into it:

mkdir build
cd build

Run CMake to generate the build files:

cmake .. -DCMAKE_TOOLCHAIN_FILE=../vcpkg/scripts/buildsystems/vcpkg.cmake

Build the Application

Within the build directory, compile the application:

cmake --build .

Run the Application

After successfully building the application, execute it with the following command:

./vender

On Windows, you might need to navigate to the directory containing the generated executable and run vender.exe.

Troubleshooting

If you encounter any issues during setup or compilation, ensure that:

• Your CMake and Git versions meet the minimum requirements.
• All the prerequisites are properly installed.
• The vcpkg toolchain file path in the CMake command is correct.
