A Comparative Study of Real-Time Rendering and Baked Rendering Based on Unity3D's Global Illumination Technique
Nowadays,games are still popular among the public,and the rendering lighting technology of"global illumination"in games gives different atmosphere and realism to the game scenes.Global illumination is divided into real-time illumination,baked illumination and mixed illumination.Real-time lighting calculates lighting at runtime in Unity,baked lighting performs lighting calculation in advance in Unity and saves the result as lighting data,which is applied at runtime,and a mixture of the two can also be used in Unity game projects(known as hybrid lighting).This paper focuses on global real-time lighting and global baking lighting rendering technology,parameter analysis and comparison of the advantages and disadvantages of the two rendering technologies,in different occasions to choose a different rendering technology,and also introduces another widely used light probe rendering technology.
