This article will explain what the 3D modeling is all about. We will see the subject in general, and then dig into the details and check the various techniques used in the modeling process.

Concepts:

You already know a lot about 3D Modeling. 3D is nothing other than the making of a character or a three-dimensional model (such as in the real world) with the techniques and instruments which software by a computer. The software that is meant for this purpose will be a 3D modeling and animation tool like Softimage. This is set of tools use to sculpt 3D artist in his imagination, This 3D model can be altered, animated and rendered into a movie in accordance with the artists need. This is what 3D modeling is if we look at it from a broad top view.

Let’s dig a little deeper:

Every 3D Model in computer representation is composed of polygons. So is like, a 3D artist draws each polygon as such? Fortunately, no! Here comes the software’s like 3DS Max and Maya to us for our design. These 3Dmodeling packages offer a wide range of models that can use an artist to create a polygonal model. The artist draws the outlines that define the models shape in three dimensions, and the software will tessellate that, in a polygonal mesh. Anything to do an artist is to define the three-dimensional profile of the character. There are a number of modeling techniques that are used on a large scale. Let’s go through them one after the other:

• Primitive Modeling: This is a very basic modeling technique and has some drawbacks. The software tool like 3DS Max provides a set of 3D primitives. The artist turns this form to his / her character modeling, using lattices, deformers etc. For example, a human head can be modeled by means of an altered sphere, a neck with a modified cylinder etc. modeling technique is more suitable for the construction of objects such as houses, furniture, etc. place for living organic modeling, since the shapes distinguish displayed and the mixture of different parts of the body not to be seamless.

• NURBS Modeling: NURBS stands for NonUniform Rational biplane. Don’t be scared by the name. In short, it is nothing but a mathematical curve, represented a set of equations. If we see this modeling technique from an outer view, all we see is a set of simple curves that we call NURBS. How the 3D function we implemented doesn’t worry too much (too much mathematics). The curves can be stretchy and have control points on them which we can use to change its shape.

• Surface Modeling: This is a commonly accepted modeling technique used primarily for organic modeling. In this modeling technique, the 3D artist creates a spline cage profile for the 3D character. The keyways intersect each other, so that a fully closed profile of the character, in contrast to the NURBS technique. As soon as the spline cage is completed, the 3D artist can apply a surface modifier on this spline cage, which is a 3D-surface filling arises from the 2D splines. This method has the advantage that it can be extended to adapt to different requirements, in which phase of the modeling process…

• Polygonal Modeling: This is one of the few modeling techniques that can be used for a variety of modeling scenarios. This modeling technique is used in both organic and inorganic modeling. The basic principle behind this modeling technique is as follows. The 3D artist draws the shape of the model he wants to do with the polygon tool. Then the polygon will get subdivided and extruded, making the model the 3D shape. This process of dividing and extruding continues until the entire model has been completed. In this modeling technique, the artist, in fact, a polygonal network creates itself. But the polygonal model is the minimal number of polygons only, and will be much smoother and perfect amount. After this stage, the artist would be a smoothing modifier on this polygon model, the model to be applied in realistic revenues and smooth looking character.

• Subdivision Modeling: This is a hybrid modeling technique, modeling the merits of both NURBS and Polygonal Modeling inherits. It also provides many other improvements. In sub-divisional modeling, the artist usually starts with a polygonal model itself. The polygonal model has already been created which is converted into a subdivision model. The sub-division model has control points and grids that can be drawn and moved, to the original polygonal model which is changing under. This modeling technique also permits the artist to be done to the degree of perfection to select a particular area. Hence, those areas which have higher detail can be assigned with more control points, and a higher NO: corner points, while the other areas will remain with a base vertex density. This provides significant performance improvement.

Conclusion:

The above modeling techniques are discussed by the artist 3d model that he will make in his imagination. The model obtained by modeling these techniques will depend on the specific modeling technique. Such a model is converted into a pure polygonal mesh and is suspended and animated based on the requirements. During the stage called rendering, the scene which contains a lot of such polygonal models, is converted into a two-dimensional image or a movie by the 3D animation software rendering engine.

High Dynamic Range images are images with higher brightness range than the normal RGB images which are of course limited to a brightness range of 256 variations per color. If you use a standard RGB image you will a have an image limitation whereby the brightest possible color will be a 255/255/255 white. RGB images therefore cannot simulate real lighting situations since the rendering look flat and lack contrast. On the other hand, HDRI images are ideal especially to recreate realistic natural illuminated scenes. In fact, HDR image is perfect in combination with GI.

Types of HDRI

Talking about the types of high dynamic range images, there are three main types- HDRI longitude/latitude, HDRI horizontal/vertical cross and HDRI light probes.

HDRI longitude/latitude

These types of images are distorted in a way that can be mapped using a spherical mapping to a sphere or a sky object. The image depiction is twice as wide and high. The X-axis of the image corresponds to the yaw-angle while the Y-axis correspond to the pitch-angle. Moreover, the horizontal center line represents the sphere equator and the top/bottom lines translate into poles.it is possible to reedit a picture but only to a limited extent due to distortions and concentration of pixels at the poles.

HDRI Horizontal/Vertical Cross

This types of HDRIs are laid like an unfolded cube and designed to be mapped to the cube surrounding the scene. The six sides of a cube are taken as six quadratic photos taken by a 90-degre photo lens. The individual photos are arranged in a way that the cut out can be folded back into the cube shape. If you combine the individual photos, it will look like a cross lying horizontally or vertically in the picture. The mapping can be used for retouching and spatial geometry since they are distortion free.

HDRI Light Probes

The High Dynamic Range images are generated through taking pictures of a reflective sphere. Indeed, it is 360-degree image representation of the actual mapping. While the outside of the circular image does not contain information, the center point shows the view forward and the edge represent the view backwards. Left, right, bottom and top are the half-radius points of the circle. The hard-to-figure geometry and distortion makes retouching very difficult.

HDRI Mirror-Ball

The depiction is created during mirror-ball photographing and not by rendering programs. The mapping format is usually in a heavy distorted form.
