What is 3D Modeling? Why is 3D Modeling Important?



3D modeling; It is the creation of all surfaces of an object in a 3D computer environment. Images are created based on datasets that determine what color, texture, and material a particular object in the image has.


There are some important stages and considerations when doing 3D modeling. One of them is the concept of rendering, which is the next stage of 3D modeling. The concept of rendering first emerged in 1960 when William Fetter created a depiction of a pilot to simulate the space needed in a cockpit. Later, in 1963, while at MIT, Ivan Sutherland created Sketchpad, the first 3D modeling program. He is known as the "Father of Computer Graphics" for his pioneering work.


In 1975 researcher Martin Newell created the "Utah Teapot", a 3D test model that has become a standard test creation. Also called the Newell Teapot, this teapot has become so iconic that it is thought to be the equivalent of "Hello World" in computer programming.


How 3D Modeling Works?


The 3D modeling program actively points the camera at an object to create a photo. That's why digital lighting is important to create a detailed and realistic render. In this direction, in the 3D rendering process, where digital lighting technology is important, the goal is to make detailed and real photo-like studies.


Over time, a number of different processing techniques have been developed. However, the goal of each render is to capture an image based on how light hits objects, just like in real life.

Apart from 3D models, image editors used for two-dimensional visualization are also used to create a simple image. This image, which is the first step for 3D rendering, is made by following some steps.


How to Create 3D Render?


It is possible to explain the rendering process as follows.


It is necessary to create a 3D model of the object to be processed in 3D.

After creating the 3D model of the object, it is necessary to create the ambient scene around that object in order to get a good space.

The third step of the rendering process needs to do the texture rendering, the object feel, and the spaces around it.

The fifth step is to set up the camera at an appropriate angle that covers every aspect of the object.

Once the camera is set up, you need to look at the adjustment of the effects it produces.

Finally, you can render the image in 3D.


Creating is a step of viewing. It allows users to look at a flat version of any image in three dimensions. Everything from the computer you use to its configuration affects the overall time for 3D rendering.


Where is 3D Modeling Used?


3D modeling is extremely important in both the private and business spheres. 3D modeling, which is frequently preferred as a hobby, draws attention with its fun structure. It is possible to see examples of 3D modeling in cartoons, animations and many other fields.


Advertisers can use 3D models to convey their messages or to highlight any product or service. The 3D model of a product allows all the details of the product to be seen. In this way, consumers can clearly see all the details about the product.


3D modeling is also frequently preferred in the construction industry. Advertising and marketing activities can be carried out by creating 3D images of various structures. In addition, it is possible to see all the details and errors in the construction project with 3D modeling. Various technical calculations and planning are created with 3D modeling, allowing the project to be examined in a realistic way.


What is Rastell?


There is another very popular methodology that allows us to get images incredibly fast, but lacks the realism that ray tracing offers. This too, rasterization is very common in game engines, and its most important advantage is that it provides a real-time experience where viewers can navigate and interact with the 3D scene.

In rasterization, objects on the screen consist of a network of virtual triangles that create 3D models of objects. In this virtual network, the vertices of each triangle intersect with the vertices of other triangles of different shapes and sizes. Each corner provides specific information and all this data is collected to form the shape of the object. Then the computer converts the triangles of the 3D models into pixels on the 2D screen and the final image is transferred to us.
