This course teaches how to create 2D and 3D vector graphics using OpenGL with C++. The learning outcomes include understanding graphics pipelines, shaders, textures, matrices, lighting techniques, and types of light sources. Students will also learn about camera manipulation, specular maps, mesh classes, and model loading. The course utilizes a hands-on approach with practical coding examples and explanations. The intended audience for this course is individuals interested in computer graphics, game development, or visual simulations, with a basic understanding of C++ programming.
