In my last article, I explained some of the logic of C4D, and when I said that C4D is actually a simulation of reality.
So how exactly is it simulated? If you understand this, then no matter which 3D software you use in the future and which renderer you use, you can quickly get started.
In 1666, Newton did a triangular prism experiment in a dark room with a small hole in the window to let in a beam of sunlight. He then placed the prism at the entrance of the light, so that the light was refracted through the prism to the walls of the house.
Later, Newton explained the phenomenon of the spectrum through various subsequent experiments and theoretical studies, white light is composed of a variety of different colors of light, and when white light passes through a prism, the light is separated due to the different refractive indices of the glass to the various colors of light.
When we understand that daylight is actually composed of different colors of light, it is easy to understand the "nature of the color of objects". The objects we see with the naked eye in nature are not essentially seeing the color of the object itself, but the color of the light reflected by the object. When the ambient light is different, the color of the object seen is also different.
So back to the 3D software, when we do any 3D creation, we must first have light, without light, then we can't see anything.
Then rendering is actually to simulate and calculate the motion of light, which you can understand as photons in motion, and they will produce corresponding motion changes when they encounter objects, such as refraction, reflection, diffusion, etc.
The material of the object is to control how those photons will move next, for example, if the roughness of the object is increased, the diffusion will increase.
So don't look at how complicated the software may be, but in fact, no matter what 3D software you use, which renderer you use, it will run according to this logic:
1. There needs to be light;
2. You need to adjust the material of the object;
3. Calculate the light movement through rendering to present the final picture.
Isn't it much clearer to learn, at least you know what you want to learn?
Many people have always followed the tutorial step by step, and every time they learn 3D, they start with modeling, and then they are persuaded to quit by boring modeling knowledge. In fact, the direction of modeling, to be honest, does not have a lot of knowledge, it is a very deep pit, from a professional point of view, it is already two completely different directions from 3D design.
When we do design work, we basically don't build complex models by ourselves, and now there are plenty of model resources on the Internet, and most of the models we want can be found. Often, we just do some simple scene construction.
The designer's focus is on "how to make the picture look good", then you need:
1. Learn to light. No matter what lighting method you use, the principle is the same, you need to highlight the main body of your picture, so that the overall picture is more three-dimensional, do not have a large ** or large dark spots, and be able to see the details of the picture.
2. Understand the material. You can't learn materials by rote, you need to understand physics and how to adjust in the software.
3. Improve your rendering ability through a lot of practice. In fact, no matter how well you master the theoretical knowledge, you still have to return to the hands-on operation, because in the actual operation, you need to repeatedly adjust different attributes, and repeatedly observe the results of the rendering, so the rendering itself is very experienced, and you must practice diligently.
