3D RENDERING. WHAT IS IT AND WHAT IS IT FOR?
Photography has been a part of our culture since the 19th century. The capture of images is considered an art that, used in an appropriate way, allows to capture the state of an object, space or person and preserve it. 3D rendering takes this concept as a starting point and offers image generation in a controlled virtual environment.
Today, the images of a product or project are not only obtained from traditional photography, but are also achieved thanks to the generation of photorealistic-looking images in specialized design programs. To learn a little more about this topic, let’s first answer the following question:
WHAT IS A RENDER?
A render is a digital image or photograph that is generated by specialized software and whose main characteristic (depending on the level of detail required) is obtaining shots with the highest possible level of realism in the scene.
These “digital photographs” have an enormous scope, since they allow capturing images of spaces, buildings, characters and practically any modeled object that one wants to represent, without the need to have the object in reality.
WHAT IS A RENDER FOR?
The utility of a render is wide. Suppose we want to build a house, but we need to show the scope and impact of the project before we start building.
The input options we have are: the creation of models, sketches, direct representation in plans with isometric views, and so on. But, wouldn’t it be much better and more attractive to show how the already built house would look like?
This is where 3D rendering comes into play. Through renderings, we can show the final scope of the project at a high level of realism, to such an extent that people who see the images think that they are showing them a model house already ready to live.
This utility is an important advantage when executing projects of any kind, since it allows knowing the final result and guarantees customer satisfaction.
Now, since we better understand what rendering is for, let’s talk a bit about rendering engines:
WHAT IS A 3D RENDERING ENGINE?
We already know it’s a render. We understand that the objective is the generation of realistic images and that at the same time keep in mind the art of photography, but how is realism achieved?
Realism is achieved by rendering engines. In any rendering project we start with the generation of virtual models with adequate measurements and proportions that adjust to reality. But, although with this we manage to spatially locate the objects, it is not enough to confer realism. The final realism is obtained with programs that are in charge of calculating, among other things: the lighting of the scene, the representation of the characteristics of the materials, the shadows, reflections and others. This way, if everything is set up correctly, the result is a photorealistic image.
TYPES OF 3D RENDERING
Real-time rendering process
The rendering in real time allows the calculation and representation of spaces, objects and characters quickly and without sacrificing the high-level technical section. This type of rendering is gaining ground day by day, since it offers the opportunity to show spaces that allow interaction and exploration. If a single image is striking, an interactive space exploits the user’s curiosity.
Offline rendering process
For its part, offline rendering allows the calculation and representation of spaces, objects and characters that have greater visual complexity and require a higher level of realism. This type of rendering is the most common and is used to generate high-level shots, but which require more production time.
WHAT IS THE EASIEST PROGRAM FOR 3D RENDERING?
Choosing a rendering program is an interesting task that can be somewhat complicated at first. There are several options and all have a wide range of advantages and fields of application. The final decision is up to the designer, who must choose the program that best suits their needs. Currently, the most common programs available on the market are the following:
3ds Max
3ds Max is a 3D modeling and rendering program that allows the visualization of scenes for product presentations at an architectural level, elements for video games and generation of animations. It has automation and allows to shorten the working time. To view software features, technical details and more, click here.
Twinmotion
Twinmotion is a program that offers an immersive experience for architectural visualization in 3D. It allows the generation of high quality images, both static and 360° with a high level of realism. It is used in fields such as architecture, construction, among others. To view software features, technical details and more, click here.
Lumion
Lumion is a software used in architecture that allows the generation of realistic images of the projects to be presented, whether interior, exterior, landscape or urban. It is an intuitive program that offers very good results. To view software features, technical details, licenses and more, click here.
Sketchup
Sketchup is primarily architectural software that offers a simpler approach. Quick visualization is part of the essence of this program. Of course, this is not a disadvantage, since it allows projects to be launched quickly for cases in which the speed of delivery prevails over the level of detail and realism.

Fusion 360
Fusion 360 is a next-generation platform that connects modeling, engineering analysis, manufacturing, and product presentation. If that wasn’t enough, it also offers a product presentation rendering environment that works great for small to medium-sized projects.
