Creation Processes of 3D Models
Creating a 3-D model takes more than just a good idea. Though it starts with the brainstorming process, the creation of a proportionate 3D model is a compilation of detailed steps, starting with a sketch-up. One the idea has been drawn out in either graph format, simple sketch drawing format, or draft depending on the project. It is then brought to the design team (often times the creative and...

Which Modeling Method Is Best?
Though there are many questions as to whether or not there is one way to create a 3D model as opposed to another, the answer lies within each person’s applicable knowledge, preferred method of design, and preference to computer software. There are three main types of 3-D design that are used today, and are considered the most popular methods used by graphics design divisions in companies....

The Evolution of 3d Modeling
3-D modeling has not always been high-tech software, and detailed mathematical equations. Today, when you hear the phrase “3-D modeling” you may think of teams of men in glasses with specialized degrees, sitting behind giant computer screens computing intricate shapes and designs. Though this is a pretty accurate description of big-name gaming and video company’s design team, this is not how 3-D...

An Introduction to Spline Modeling
A spline is defined as a special function involving polynomials in the mathematics realm. It can also be used to describe an alternative way to figure interpolation problems, and is an easier less governed function than polynomial interpolation. For those not familiar (or interested) in mathematics, the term spline may be more familiar as it pertains to computer science. In this field, and...

The Creation Process of a 3D Model: Rendering
Rendering is the third and final step in the simple creation of a 3D model. Rendering refers to the image being visualized with images being created from the 3D model. There are many features of a rendering, these include; transparency, shading, shadows, reflection, depth of field, caustics, fogging, bump-mapping and texture mapping. These features are the most commonly used when an object...

3D Models for Use in Geological Modeling
Geological modeling serves the purpose of creating 3D models of sections of the earths crust. These 3D models are unique as they can be created with different types of simulations of rocks, even the types of cells within the rocks. 3D models allow seismologists to predict certain events within the crust of the earth from shifting plates to eroding areas of the crust, or new growth within certain...

Types of 3D Modeling: Polygonal Modeling
There are three common shapes created with the use of polygonal 3D modeling; triangles, quads, and elements. Triangles are formed when three sided polygons are uses, quads are formed with four sided polygons are used, and an element is created by a group of polygons connected together at a shared point.
Polygon modeling refers to 3D modeling which use polygons to create the shell of a 3D model....

Creating 3D models with NURB Modeling
NURB modeling or, non uniform rational b-spline modeling creates 3d models with varying surface representations. This type of modeling allows for the curves that we see in sleek vehicle models and architecturally curved buildings. Specific aspects of a NURB model include; knot vector, control points and the order of these items. Control points are arranged in a specific order, thereby creating...

The Three Methods of Modeling
There are three types of modeling that are used to create a 3D model, these are; spline modeling, box modeling and poly modeling. The first type of 3D modeling discovered is spline modeling. Spline modeling has also been referred to as patch modeling and allows a curve to be created with the use of two control points. These points are created in multiples to create the skeletal system of the...

How to Smooth the Edges of a Polygon Model
Polygon models which have surfaces that appear curves are actually created with tiny series of lines. These lines can be smoothed in the rendering process making the lines appear smoothed, and authentic. Many created 3D models are created from these series of tiny lines, but have the appearance of curved surfaces such as furniture, or vehicle 3D models. Sharp angles and corners are the targets of...
