What are the main points of 3D learning?
1. No one brought up by a master can become a master. Just remember this sentence. Unlike other programmers, 3D programmers can learn better and better. Almost by experience, after learning 3D to a certain height, they can never improve without advanced mathematical knowledge. I think this is the most difficult. I think 3D is not difficult at all. It is nothing more than spatial analytic geometry and a little matrix transformation, plus a little very simple knowledge of geometric optics, nothing profound. On the contrary, I think the most difficult thing is a thorough understanding of physical laws, such as field theory and tensor analysis. It is the most difficult process to describe the laws of physics in mathematical form and then express them in computer graphics. This is what most top graphic masters in the world are doing, such as Jos Stam. He who places his hopes on others will never become a master. 1, there are many experts, but experts will not tell you the essence easily. 2. No knowledge can be truly understood and mastered without its own independent research. Like-minded people don't have to be around. Now it is a global village. You can download it on the paper net of the Master. What else do you want? Learning 3D has nothing to do with learning 3D Max! If you want to be an expert in 3D Max, you definitely need to learn some 3D knowledge (it doesn't need to be deep, just know the meaning of the parameters, and you don't need to know the origin of the parameters), but conversely, you don't need to learn 3D Max at all. You don't have to learn 2D to learn 3D. 2D is just a special case of 3D. Masters are basically self-taught. Everything needs to be taught. What about innovation? Remember this, and you won't take a detour. 3. "Describing physical laws in mathematical form" has long been done by others (physicists/mathematicians), and graphic researchers are only applying the existing achievements. J.Stam won the SIGGRAPH Lifetime Achievement Award. This man has done many things, many of which are related to physics. Of course, R.Fedkiw and J.B are also good at ... three main fields in graphics and images: methods based on physical simulation, methods based on large-scale data sampling and advanced image processing ... Anyway, they are good at mathematics and familiar with the achievements in other fields. Graphics is not only simple knowledge of geometric optics, but also knowledge of function approximation, numerical solution of differential equations, Fourier analysis, harmonic analysis, wavelet analysis, probability statistics and so on. Field theory and tensor analysis are very simple in physics. Let's compare it with chord theory. I don't think experts are selfish. At least meeting a good senior will make you take fewer detours, and the other party will give you correct guidance instead of imparting knowledge.
