Maya (Illusion) of 3D Art

I always had an interest in the imaginary world since I was in Standard 8, which grew with time and made me take up a Multimedia course during my graduation. This course included a thorough understanding of a combination of 2D and 3D. In this blog, I’m going to share a little about 3D art.

Let’s first understand what 3D is. In layman’s language, 3D refers to three-dimensional space, and in technical terms, 3D means “any method accomplished for recording three-dimensional illustration or information”.

3D Art Process

Modeling is the process of creating a demonstration of any three-dimensional surface by using different software tools such as Autodesk Maya, Max, etc. There are two types of modeling - Organic and Non-organic. Organic modeling includes naturally existing things, such as human beings, animals, and conceptual characters. Non-organic modeling includes man-made things like buildings, cars, and conceptual designs. Texturing is a process of making the 3D model more practical. This process includes various stages like unwrapping, UV Snapshot, etc. Lighting is the process of achieving a real-world light effect. This contains a blend of use of artificial light sources such as lamps, bulbs and others, as well as natural lighting through daylight settings. After this comes stages such as animation, visual effects, compositing, and rendering.

3D Art Technologies utilized in various fields

Television advertisements for companies such as Pepsi, Sony, LG and several others have used 3D skill for their creations. All action, war, and drama movies such as Avatar, Harry Potter, and 300, use this technology at a higher level. One of the major fields using 3D, is gaming. Games like GTA 6, and Call of Duty have amazing effects accomplished by expertise and motion capturing.

Motion capturing is an additional incredible technique in 3D art. It’s a process in which the recordings of individual movements are translated into digital structure by sensors on each position. Post this, the demo is converted into 3D after incorporating more amazing effects. There are many kinds of capturing techniques, such as performance capture, mechanical motion capture, electromagnetic motion capture, and optical motion capture.

3D Printing

After television, gaming, and movies, one of the most revolutionary fields is 3D printing. It is a process of creating solid objects from computer applications. 3D printing basically modifies the way we make things. Now, the question is: how does this process work? The entire process commences with the creation of a design in 3D software. Post that, the design is exported into a 3D print pipeline which makes the object of this design, and post that, a 3D printer prints the object by adding layers into the cross-sections.

These objects are printed from different kinds of processes using different materials such as rubber, wax, ceramics, and even chocolate! Today, this technology is used in various fields such as architecture, industry, and by industrial printing companies. For example, Nike uses 3D printing processes for their shoes. With its success, local printing is seeing a massive growth day-by-day. According to local printing, an organization provides printing services to its client.

Conclusion

I think 3D printing will change the standards of the industrialised world. This technology is able to print different colours and materials that already exist and will continue to expand with time. People will be able to print more and more products according to their choices. 3D is bound to have an impact in many areas where high-end technology plays an important role, like product design, movies, entertainment, and more. In the coming years, this field will be closely followed, with young talent ready to provide these services. India can play an important role in this revolution. But like any technology, it needs to be handled carefully as even weapons can be produced using the skills and technology related to 3D.
