What is 3D Modeling?

If you have seen a sculpture ever in your life, you already know quite a little about 3D Modeling. 3D Modeling is nothing but the creation of a character or a model having three dimensions (as in real world) using the techniques and tools provided by a computer software. The software we use for the purpose will be a 3D Modeling and animation tool like 3DS Max, Maya, SoftImage etc. The tool will provide a set of tools that a 3D artist can use to sculpt or model, an object in his imagination, into a 3d computer representation. This 3D model can be altered, animated or rendered into a movie in accordance to the artists need. This is what 3D modeling is, if we look it from a broad top view.

Every 3D Model in computer representation is composed of polygons. The polygons may have three or more vertices and such hundreds or thousands or even millions of polygons may comprise a 3D Model. So is it like, a 3D artist draws each and every polygon as such? Fortunately, no! Here comes the softwares like 3DS Max and Maya to our rescue. These 3d modeling packages provide a wide variety of modeling tools that an artist can use for creating a polygonal model. The artist will usually draw the outlines that define the models shape in three dimensions, and the software will tesselate that into a polygonal mesh. All that an artist has to do is define the 3 dimensional profile of the character he has in his imagination.

Various categories of 3D modeling

  • Interior and Exterior modeling
  • Pros modeling
  • Character modeling

3D Modelling – 5 Tips on How to Make Incredible Character Modelling

8 tips to improve your character modelling skills and reach a professional level in an easy way.

1. Have a concept. I know that modelling is fun, but starting without a concept is like setting sail’s without a map. You need to know what you are modelling in order to actually model something useful. Make a fun project out of it and draw a character. It does not have to be perfect it is just to get an idea of what your goal is.

2. Do your research. The human brain is fantastic but it cannot remember all the details of for example a head. So having reference pictures is crucial. Also if you are modelling a cartoony character.

3. K.I.S.S. “Keep it simple, stupid!” It is very easy when you are working to keep on adding edge loops. This is a trap and it will ruin your model. So keep it simple, have as few edge loops as possible. I see a lot of beginners losing track of their model because they just keep on adding edge loops.

4. Make a nice flow. A nice flow relates to doing your research. You want to have a nice edge flow in your character, especially the head. The edge loops should be placed where the muscles in the face are placed. A great way to secure that is by drawing the visible lines in the face before modelling.

5. Looking forward. When you are modelling try to look forward. For example; the arms will in most cases bend, this means around the elbow you want at least 3 edge loops to make a nice deformation. The same thing goes for the mouth. You want edge loops around the mouth so it can deform correctly.

6. Check your concept. Check your reference regular while modelling, to see if your 3D model fits the reference. You will be working on same models for a long time. In the mix your 3D model can unfortunately change shape so it does not look like the concept anymore.

7. Naming your stuff. We have all been there. We look in a scene and everything is called final final something. This is not a good solution. A good solution is to call your models what they are. For example I would call the left hand of my character: hand_L_01_GEO. It is pretty simple. GEO is added because it is geometry. If it is a joint I would add JNT.

8. Keeping it in squares. Your model should only consist of square polygons. This means no triangles or faces with more than 4 sides. This is hard to learn because you will be fiddling around with triangles. It feels like an unsolvable puzzle. But you will get better and faster. It is one of the most important parts in 3D modelling. If your model has triangles if will deform badly.
