This week, I looked up more relevant literature on rendering, and distilled the information that was useful to me in different kinds of literature, and recorded and saved it.
Idea01: GPU (Graphics Processing Unit) and CPU (Central Processing Unit) are two types of computer hardware that are commonly used for rendering.
CPU rendering is when the computer’s CPU is used to do calculations for rendering. This method is usually slower than rendering with a GPU, but it can be more flexible because CPUs are made to handle a wide range of tasks. CPUs are usually used for rendering applications that need a high level of accuracy and precision, like scientific simulations and photorealistic rendering. In GPU rendering, on the other hand, calculations for rendering are done by using the computer’s GPU. GPUs are made for rendering and can handle a lot of data at the same time. This makes them perfect for real-time rendering applications like video games and virtual reality. GPUs are also often used for architectural visualisations and product design, which are two other types of rendering.
Both GPU rendering and CPU rendering have their pros and cons, and which one to use will depend on what the application needs. Many modern rendering programmes can do both CPU rendering and GPU rendering, so users can choose the method that works best for them.
