Difference between 3D Modeling and 3D Rendering

1. 3D modeling and rendering differ depending on the results

3D modeling results in a 3D file that contains a geometric representation of an object. A model has three dimensions, like a real physical body. To create a model, a 3D artist needs exact dimensions and a complete understanding of the form.

The representation is an artistic representation of modeled objects such as still images or animations. More precisely, it is a computer simulation of a plan or sequence. The resulting images or videos are called rendered or rendered.

Video reproductions are particularly interesting and entertaining in terms of digital storytelling. As videos require 3D product models, a marketing professional needs both 3D modeling and animation to be able to publish one.

2. 3D rendering follows 3D modeling

3D modeling and 3D rendering are two steps in the creation of CGI. First, a 3D artist builds a 3D model. In most cases of use, the models need a realistic look, as if they were made of wood, stone, glass or any other material.

Now, the rendering process begins. At this point, also called visualization, a 3D artist builds the scene. That is, organize the models in a three-dimensional space, customize the lighting and position a camera, in addition to granting several options. As everything is ready, the time has come for the calculation to obtain images. A computer simulates a perspective of models with all the lights, shadows and textures.

The rendering result can be indistinguishable from a photo: most customers have no idea that many product images are 3D graphics.

3. 3D modeling and rendering need unlike tools

An independent 3D artist usually works in both modeling and rendering. On the other hand, in a 3D modeling studio, the modeler and the rendering engine are two different professions. The reason is that 3D modeling and 3D rendering require different techniques and software, and specialization provides better results for a more predictable workflow.

Sometimes, a client can create a model by itself, that is, export it from a CAD application or use a 3D scanner. Otherwise, 3D artists will use modeling software such as SketchUp, 3ds Max or Maya.

All previous modeling applications have a rendering engine. However, 3D rendering professionals use more specialized programs such as Mental Ray, V-Ray and 3Delight.

4. 3D models can be reused in other 3D representations

As a geometric object, a 3D model is very easy to edit. In addition, you can travel from rendering to rendering, giving completely different images. There are visualizations built entirely on ready-to-use models.

In practice, this means that a model can be used in multiple shots of heroes and lifestyle images with different backgrounds, with different purposes. Slightly optimized, it can be part of an application.

5. 3D modeling and rendering find different uses

3D rendering as a service is useful to demonstrate the benefits of a product or service. In addition to the product and presentation pages, it provides amazing product images for virtually every marketing channel, from websites to TV commercials. There are many ways to make marketing more effective with 3D rendering.
