So, if you are a beginner in 3D modeling, it is really great to know that you can create almost anything you want. However, you need to learn how to get good at 3D modeling through hard work and determination. This article presents some of the best 3D modeling tips and techniques that can be quite useful to beginners.
However, before you go through the article, you need to have a good knowledge of 3D modeling basics. In this article, we will help you learn how to practice 3D modeling by utilizing the tips and techniques.
A Few Basic Modeling Tips for Beginners
What is 3D Modeling?
3D modeling is the process of creating three-dimensional images, drawings or animations. These are often used in game development and product design, where models offer an idea of how a project will look in the real world.
The 3D representation is usually done mathematically by taking the points in a virtual space and manipulating them. Points that make up the shape of an object are called vertices.
A 3D artist usually uses advanced software to manipulate the points in virtual space. The process involves a digital object to fully animate and bring special effects to the core of a model. The core of a model is its mesh, which consists of points in space.
3D shapes are sometimes made from joining polygonal triangles or quads. This is why creating a shaped surface requires plotting out the positions of points on a two-dimensional grid. Overall, 3D modeling is important to plan and design work for architects and engineers.
Here are some of the best 3D tips that can help beginners with their 3D modeling practice.
Geometry and texture
One of the features tools is the Texture to Geometry tool which allows modelers to create a base mesh. You can start off by creating a plane with the same aspect ratio as the image that is projected. Once a texture is assigned to a plane, plane geometry can be selected and modified by using Modify, Convert and Texture to Geometry. An input image can then be selected and applied.
Quads for design
Considered as one of the basic 3d modeling tips for beginners, the use of quads for subdivision offers seamless interaction with the object. You can use triangles but stay away from N-gons. Predictable nature and easier access to enveloping while skinning makes quads a preferable choice among modelers.
Backface Culling has to be turned on in your Shading options if you want to import a million geometric shapes at the same time. A cluttered viewport will try to bring all of them in at the same time making it lag back for a moment.
Realistic and animated characters require proper movement of facial bones and muscles. It is, therefore, necessary for modelers to have a thorough understanding of how movement takes place in facial muscles. It is imperative to have an idea of the character and its internal movement.
Minimum number of polygons which provide maximum detail ensures that complicated models are easier to design and interact with. Boolean tools can also help in creating complex-looking models in an easy and creative manner.
One of the most appreciated 3d modeling tips and tricks is to get a repetitive shape to use the Animation Snapshot command. It is available under the “Animate”menu. A piece of geometry which is traveling along a motion path will create a duplicate copy of model every frame. Chain modeling like street lights and city street networks are good areas where this can be applied.
If you are considering a mesh retopologization, then look no further than Create Polygon Tool. It helps to draw a shaded part over the top of the high-resolution image to create a lower resolution one. This tip is really helpful when it comes to creating 3D design for beginners.
For creating realistic 3D models, you need to be proficient in employing the 3D CAD Software. For learning how to improve 3D modeling skills, you need to have a thorough understanding of the different 3D modeling techniques. So, now let us have a look at some of the commonly used ones.
Commonly Used 3D Modeling Techniques
3D modeling techniques usually connect point sets with different surfaces, curved or linear, and utilize geometry related data for creation of wireframe models. In order to develop 3D models which have distinctive character of their own, you need to be creative and imaginative. This is similar to creating spectacular animation by leveraging your skills. 3D modeling is a teamwork wherein each creative artist would take care of a unique aspect of the character design.
From the perspective of 3D experts, here’s how to get better at 3D modeling by using the popular techniques.
Subdivision or Box Modeling
The technique is polygonal modeling based
Work is started with a geometric primitive
The shape is refined till the desired look is achieved
Box modelers prefer to work in stages to remain organized
Low resolution polygon meshes become the starting point
Hard edges are made smoother through mesh subdivision after refining shapes
Details are added as deemed suitable
Sub-division of surfaces and shape refinement are repeatedly carried out
This is done till sufficient polygonal details are suffused in the mesh
The shape would now evolve which would materialize your concept accurately
This is most commonly used polygonal modeling type
The technique is used widely along with edge modeling methods
Contour or Edge Modeling
Here, the artist does not start with a primitive shape
The creation of the model occurs in pieces
Loops of polygonal faces are placed with major contours
Gaps between contours are filled
Edge flow and topology needs to be managed meticulously for proper face modeling
High precision can be obtained with contour modeling
Model building process becomes easier if it is started with the outline of the shape
Remaining part is modeled after drawing the outline
Creating the shape from a properly defined solid polygonal mesh is not desirable initially
Ideal for building character’s lips, nose, eyes and jawline
Remaining parts spontaneously gets managed
Spline or NURBS Modeling
The technique is particularly used in modeling objects for industrial and automobile units
The model is constituted of surfaces which are smoothly interpreted
A mesh is heaved amidst two or more Bezier curves
The tool used for creating NURBS curves is functionally similar to Pen Tool
The Pen tool is used in Adobe Illustrator or MS Paint or similar program
Drawing of the curve takes place in 3D scape
Editing of the curve is done through a series of handles called Control vertices
For perfect modeling of NURBS space, curves are placed along major contours
The 3D software then spontaneously gets the inlying space interpolated
The modeling method is very fast
Objects like wine glasses, plates, vases and other objects can be modeled
Any object can be created with the help of algorithms
No need of generating shapes manually by the 3D artists
Creation of scenes and objects takes place with the help of user definable rules
Parameters can be set for procedurally modeling organic objects like trees and leaves
Objects that are highly complex in nature can be created in this manner
The long time needed to manually create the models is waived off
Organic creation of meshes take place in digital sculpting
Wacom tablet device is used for molding and shaping the model
The digital model resembles the real shape created by the sculptor with hand
Real clay modeled with rake brushes yield shapes which are digitally emulated
Creature and character modeling can be impeccably done with digital sculpting
The process of creation is fast, efficient and conducive to higher productive
Artists can work with meshes of high resolution
Meshes can carry millions of polygons
Unparalleled level of detailing in surfaces can be obtained with sculpted meshes
The aesthetic appeal of the shape is more and the model is spontaneous
Objects are photographed from different angles in good lighting conditions
Images are uploaded to the 3D modeling software for creating a 3D representation
Real-world data is used for 3D model creation, resulting in photorealistic outputs
Results may also generate UV Maps and textures so no need to create again
You might need to rework the mesh. In that case, you need to recreate the UV Map
The camera will capture both objects and surroundings. So, it will need more clean-up
Some part of the object might not be accessed resulting in mesh holes
The holes in the meshes need to be filled in the later stages
Both small and large objects can be created with it
A variety of digital simulations are present
Simulations can be related to fluid, physics, cloth, ocean, particles, soft body, etc.
During the simulation, a set up of parameters and objects are created
A computer calculates the happenings in each frame and the movement of objects
Results can be used to develop animation along with objects and scenes
Instead of modeling each frame manually, two simulations can be combined
More than focusing on the shape, you need to fine-tune and tweak the parameters
3D Modeling Techniques
Polygon modeling is one of the 3D modeling tools that allow you to create a 3D model with computer graphics. It is also similar to box modeling. Polygon modeling provides faster-rendering speed than other types although it does not permit a full designing freedom in modeling. You can still get the knowledge of 3D modeling basics.
This technique will often start with a simple shape that looks flat (with no depth). Then the model is built piece by piece with the same tools used for box modeling but in a detailed way. The importance is given to working with edges and vertices with emphasis on using quads in the topology.
Boolean modeling starts by cutting away or adding an object to create a new shape. Even this modeling is similar to box modeling. The process works by creating basic shapes with box modeling and then sticking different shapes with Boolean modeling. It includes difference, intersect, and union.
Difference: The difference operator is an ordinary one among the group. In this step, you cut away the shape from one object to the other.
Union: These merges the two objects while intersect saves the geometry shape that the two objects share.
Boolean is really helpful in creating shapes which are otherwise time-consuming and can help with your 3D modeling practice.
Modular modeling is a process of creating 3D assets that are easily created and configured for various purposes. Modular modeling can be an asset-heavy or lightweight system, depending on how the modular models are used in the project.
Modular work in 3D assets means that all the pieces used have a standard size and shape to be combined easily into larger objects. This approach has many advantages:
Work done in separate parts can be combined with other assets seamlessly since the results will match well.
Modules are more reusable, saving you precious production time.
Making prefabs saves on production turnaround times and allows for adjustments once your scene is set up.
Kit bashing is another type of 3D modeling technique. An artist will start with a model or a kit and remove what they don’t need to pursue their vision for the project’s art style or story.
Kit bashing is the process of taking a pre-existing model and tweaking it to be something else. For example, you may want to scavenge windows and doors from several different models and then arrange them on top of each other in a 3D space until they look like an apartment building. You’re rigging individual pieces onto another piece with invisible lines that indicate what goes where.
This makes things considerably easier when populated with hundreds of interior items as you combine them into a detailed object. Overall, it is the best idea if you want to give your scene a polished look with more details.
This is another new method of 3D modeling that was introduced soon as laser scanning technology gained traction. In this technique, an object is scanned to develop a digital representation of it. The scanning is usually done quickly, but you should remember to clean up the geometry before using it.
If you are confused about choosing what type of3D modeling to use to get the best result, then techniques will kickstart your hidden skills. In most cases, going with a combination of 3D modeling techniques is a great idea. If you want to explore advanced things in 3D skills, these 3D modeling tips and techniques are a great idea.
