Real-Time-Graphics

Gaming Engines and Real-Time Graphics Real-time graphics aim to show interactive images at smooth frame rates, usually 30 to 60 frames per second or more. Game engines provide the tools to build scenes, manage physics and input, and most importantly, render the visuals that players see. They balance creative goals with hardware limits, so developers can focus on ideas like environments, characters, and gameplay rather than low-level rendering details. A good engine separates concerns into a rendering pipeline, a scene graph, materials and shaders, plus lighting and post processing. The rendering pipeline converts 3D objects into pixels on the screen in real time. It uses culling to skip unseen objects, and it runs many small tasks in parallel on the CPU and GPU. Materials define how surfaces look, and shaders determine the color and lighting at each pixel. Lighting can be baked for static scenes or computed in real time for dynamic scenes. ...
