I hate rendering. Can’t stand it. I would be positively elated to never have to render anything ever again. That leads to the obvious question. What is rendering, and why do you hate it so much? Since a lot of my past work has been in 3D graphics and animation, the context from which I invoke the word “rendering” is probably important. Rendering is when you, as a digital artist, ask the computer to please take all of the 3D models, texture maps, particle effects, and lighting trickery, and pass the whole mess through some sort of prettying sieve. The pixels extruded out the other side of this process should be in the order that you expected, or at least arranged nicely. Depending on the renderer you are using and what you tell it to do, you can get all sorts of different looks, anywhere from photorealistic, to pre playstation 1 era polygon soup. Every computer generated image had to pass through a renderer of some description. Some just light up the screen pixels you suggest to the rendering software might need lighting up. Others read the geometry in the scene and calculate the way that light bounces around the objects turning each impacted surface into a new light source, with it’s own colour and scatter parameters. The thing calculates the movement of light. No matter how efficient the calculations are, that’s a job that is going to take some time.
