On a very high-level, STL library has lot of containers that are often used, and it has few methods that could be applied on those containers. Basically STL has several ready-to-use common classes that you can use in your C++ programming. We’ll cover STL in detail probably in a separ...
This example project uses theigl::opengl::glfw::Viewer, therefore it requires the glfw module of libigl. This shows up in the CMakeLists.txt igl_include(glfw) …target_link_libraries(${PROJECT_NAME}PUBLICigl::glfw) Suppose you also wanted to use the triangle module in libigl. Then you ...
