Why 3D will have a great impact in the near future
3D considered as the most realistic art around the world, 3D art is also widely used in manyimportant fields, may be it is not used as an explicit art, but as a complementary service thatoverlaps with other services/industries to come up with various types of integrated product likefor example the filmmaking industry
So why you must pay attention to the 3D art?
As we have mentioned before, 3D art is widely used in many fields, and in the upcoming months3D art will be witnessed a great evolution as it interacts with many other fields, not only for thatreason you have to pay attention to 3D art, but there are many other reasons, as 3D art is oneof the most interactive arts as it is the most realistic one, it also can simulate reality in a veryprofessional way and that makes 3D art very expressive and illustrative art, now let's take a lookabout some of the new 3D artbased technologies that will conquer the world.
You may have heard about this technology before in the near past, 3D printing does notconsider to be a new technology anymore, it has been posited into the market several yearsago, maybe it didn’t grow as fast as it was expected, and the reason behind that might bebecause of the high cost of its material, but that was in the past as eight years ago, a smalldesktop 3D printer cost $20,000, it’s now $400 and the price will continue to fall, that will openthe chance of 3D printing technology to be widely used by various society’s strata without costsconstraints. 3D printing technology is used in many fields, like medicine, industrial design,architecture, fashion, and even in the food industry! Imagine that you can print your food insteadof being cocking it, isn’t that great?
Virtual reality is a very interactive and technology, as it is a computersimulated life, replicatesan environment that simulates physical presence in places in the real world or imagined worlds. Virtual reality can also recreate sensory experiences, which include virtual taste, sight, smell, sound, and touch. It is mainly used as an immersive multimedia for creating higher interactionwith certain products, that’s why it is now widely used in the gaming industry and sooner will bewidely used in filmmaking industry to product more interactive movies.
Augmented reality (AR) is a live direct or indirect view of a physical, realworld environmentwhose elements are augmented (or supplemented) by computergenerated sensory input suchas sound, video, graphics or GPS data. Augmented reality technology is used nowadays as a marketing technique as its is veryinteractive and so gives higher engagement rates between the product and the customer/user. So, after knowing those new technologies, let’s know more about the 3D art itself and the services below it. 3D art is not easy nor hard, it seems to be complicated, but in case you love it, it would be your entertainment not only your work.
To produce a 3D piece of art, you first need a very high specification computer that mainlynamed “Workstation” and your favourite 3D application like Maya, Cinema 4D, 3D Max, Blender..etc. Tools is ready? Now let's step forward to the main steps of creating 3D process. Most of the art production pass by three main stages, preproduction, production, post production, and each process has its own subprocess that all aims to create a piece of 3D art even it is a model, image or a whole movie.
This stage concerned about what you are going to produce and collecting inspiration data thatwill help you in the next process, it may be a previously made storyboard, a simulated photo of acertain scene, or whatever you are going to make, and it mainly called “Concept Art”. Collect your data, make your sketches or having it, and inspire from real models and be ready for the production process.
It is the process of shaping or sculpting the 3D model, even it is organic modelers tend to havea sculpture background and specialise in building the characters and other freeform surfaces, orhardsurface modelers often have a more industrial design or architectural background, and assuch they model the vehicles, weapons, props and buildings, i.e: turns 2D sketching into 3Dmodels. Modeling involves connecting a set of points with various geometric data such as linesand curved surfaces with the goal of creating a wireframe model that represents a three dimensional object.
Texturing is aiming to give the 3D model its final look, as textures are 2D images that aredesigned to influence a 3D model's appearance. Whether it's simply to add color to a model likeone would paint a clay sculpture, or to govern a specific material attribute.
Rigging is the process of adding bones to the 3D model or defining the movement of it if it is amechanical object and not a character, and it is a very important step before animation takesplace. It is also involved in developing cloth simulation, so as well as making a character able toclench their fist or rotate their arm, rigging and clothing are responsible for making their costumemove in a believable manner.
After applying rigging process to your model, you can then apply motion to it if you are going tomake an animated movie or something alike, animation can be done by manipulating the rigcontrols to pose and move the model/character.
Lighting and Rendering
In the lighting and rendering process all the coloring and material properties are added, likewood grain for walls or furniture, fabrics for furniture and curtains, and more. It also adds thesheen to furniture, the translucencies to curtains, and the effects of lighting on everything orevery model you have created, and that to come up with a model/scene that looks realistic orcartoonlike.
Compositing is the process of combining all the 3D elements of the scene together afterapplying rendering to it and then applying extra needed editing in its texture, lighting, contrast...etc to produce the final version of the image/movie and publish it to the audience. While producing a movie you will pass by two extra processes which are video editing and sound editing. Now your 3D piece of art is ready!
There is another kind of art that simulate the threedimensional modeling, but it is depending ononly two dimensions, which is 2D Isometric art, and the steps of drawing it are:
In isometric, all shapes are drawn with three planes, the upper, side and front planes, except thecircle, that's why when starting drawing isometric, you will have to make three axes, two of themare above the main horizontal plane/axe with 30 degree angle and a middle perpendicular axeto it (with 90 degree angle), like shown in the next figure:
While drawing geometric shapes in isometric, horizontal lines should take 30 degree rotationangle, perpendicular lines kept as they are and also the sloping lines, here is an example of howto draw an isometric cube:
For the wide use of shapes to produce a huge work of isometric art, like a game for example, itwill be exhausting to repeat those steps for all the shapes, so you can overlook them by creatinga ready made “Actions” in the illustrator program, follow the next steps to make the isometricaction:
Open a new file and draw three similar squares:
Then apply the action for each square separately as the following:
From the Window tap, choose “Action”:
Then choose “create a new set”:
Then, create new action:
Press “Record” To apply action for the left side do the following:
Choose the “Scale tool” by double clicking on it, and set the non-uniform vertical value as 86.602%
Then choose “Shear tool” and give it the value 30
Then choose “Rotate tool”, and set its value as 30
Then stop the “Record”
Repeat the same steps but with different values to make the action of the top side, as the following:
Choose “Scale tool”, set the non-uniform vertical value as 86.602%
Then “Shear tool”, and set its value to 30
Then the “Rotate tool” and set its value to 30
Then stop “Record”
Finally, applying action to the right side:
“Scale tool”, set the non-uniform vertical value as 86.602%
Then, “Shear tool”, set it as 30
“Then the “Rotate tool” and set its value to 30
Then stop “Record”
Here is a bouns step that hepls you to be more faster with your process of applying action, by creating ready made actions buttons for your action, to apply it with a click:
Now, after knowing the whole process of 3D art production generally, and also the process of 2D isometric that simulates 3D scenes, let’s see the next example that shows the difference between 3D isometric and 2D isometric in animation:
It is obvious to you now that 3D isometric is better in animation than the 2D that only looks three dimensional, and that’s because of the rigging process, that gives the model its skeleton and allow it to be animated freely, and also because of the third dimension that gives the depth to the piece of 3D art, which is lack in the 2D in both creating and animating processes.
