August 10, 2022

What is a render?

Surely you have ever wondered what a render or 3D perspective is?

Well, a render is a digital image generated in a computer, in which buildings, objects or characters are represented in three dimensions, with the purpose of showing a realistic aspect of the scene or object. For example houses or buildings.

In the world of architectural design, visual representations are essential to convey the vision of a project. And that's where renderings come into play.

But what are they really and how do they work? In this definitive guide, we'll give you a complete understanding of renderings and how to get the most out of this powerful tool. Renderings are digital representations of an architectural design that provide a realistic and detailed view of the finished project. These images, created using specialized software, allow architects, designers and clients to visualize what the building will look like before it is built.

We will explore the different types of renderings, from basic black and white to more detailed, photorealistic renderings. In addition, we will discover how renderings play a crucial role in project presentation and how they can influence decision making.

Whether you are an architect looking to improve your presentation skills or a client interested in understanding a project in more depth, this guide will give you the knowledge you need to understand renderings and their impact on the world of architectural design. Let's get started!

The process of creating a rendering is carried out through various techniques such as modeling, texturing of materials, lighting, distribution and even specific photography techniques in order to achieve photorealistic images.

In many occasions, the renders are so real that they can be easily mistaken for photographs, in that case we would be talking about Photorealistic renders.

What is a render for?

The 3D has a wide variety of possibilities and its use is very broad.

For years, rendering has been used in the architectural industry as the main tool to convey the architect's or designer's vision to the client.

In the case of real estate, they are used as visual support in the presentation and attraction of investment for new developments, and as part of the sales strategy for the pre-sale and promotion of the project.

How is an architectural rendering done?

The 3d rendering in architecture, always following the style and needs of the client, is done in different phases:

3D Modeling

The volumetry and scenes of the project are created following the exact measurements.

Views

In this phase, the points of view of each scene are fixed, i.e. the camera is positioned to enhance the best perspective of each room.

Texturing

materials are applied to all surfaces and elements following the real scale measurements. To find high quality textures you can go here.

Decoration and vegetation

It is time to work on the atmosphere and the environment of the image. Decorative elements are added, as well as different types of vegetation, which bring life and realism to the image.

Lighting:

the lighting of each scene, both natural and artificial light, is defined.

Rendering:

Once all the details of the rendering have been worked out, the final image is exported in high definition.

Postproduction

Finally, all architectural renderings are processed in an editing program, in which the details are enhanced to give more definition and achieve an image with the greatest possible hyperrealism.

Types of renderings

After having seen in detail what a render is, we are now going to see the different types of renderings that exist in the market.

360 3d virtual tour

A 3D Virtual Tour is a 360º images achievement with a navigation system that allows you to walk freely through the spaces of the virtual tour. Getting to recreate the spaces of a house in a realistic way without it being built.

Product rendering

Rendering a product is the process of generating a 3D image or a 3D animation from a model, using a computer application, achieving the final product with a controlled finish of lights, textures, angles and volume.

The main difference with a photograph is that in photography you do not have the same control over position, scale, volume, textures and lighting.

3d infoarchitecture animations

A 3d infoarchitecture animation is based on giving life to those objects that do not have it (for example buildings), these objects can be rotated and moved in a three-dimensional space. It is the representation of an architectural project through the production of 3D computer graphics.

Low cost 3D plans

It is the representation in three dimensions of data that have been stored with reference to a geometric model with the objective of offering a complete 3D image as a complement to the traditional plan, in order to offer a better view of the project from another perspective.

Benefits of using renders

The use of renderings offers a number of benefits for architects, designers and clients alike. First, renderings enable better communication and understanding of a design by providing a clear and detailed visual representation. This avoids misunderstandings and facilitates informed decision making.

In addition, renderings save time and money by allowing changes and adjustments to be made before actual construction begins. This avoids costly mistakes and rework, as any problems or issues can be identified and fixed at the design stage.

Common misconceptions about renders

Normally for people who do not know what a render is, some concepts about its usefulness and benefits can lead them to confusion, there are some common misconceptions about renders. One of them is that renderings are only for large scale or high budget projects. In reality, renderings can be used in projects of any size and budget, as they are an accessible and versatile tool.

Another misconception is that renderings are always 100% accurate and represent exactly how a project will look in reality. While renderings can be very realistic, it is important to keep in mind that they are digital representations and there may be some differences from the final built version.

Tips for creating high quality renders

Once you are clear on what a render is, you should know that there are different rendering qualities in the industry and to create high quality renders, it is important to follow some practical tips. Firstly, it is essential to use reliable and up-to-date rendering software. This will ensure that you can take full advantage of the program's capabilities and get realistic and detailed results.

In addition, it is important to pay attention to detail and use realistic materials and textures. This includes considering how materials will look in different lighting conditions and how they will interact with the surrounding environment.

Best software and tools for rendering creation

There are numerous programs and tools available for creating high quality renderings. Some of the most popular include:

Autodesk 3ds Max,
SketchUp
V-Ray
Blender.

These programs offer a wide range of features and customization options to create realistic and detailed renderings.

Frequently Asked Questions About 3D Renderings

What is a 3D render?

A 3D rendering is a photorealistic digital image generated by a computer from a three-dimensional model. In architecture, it is used to visualize what a space, building, or home will look like before construction, with a level of realism that can be virtually indistinguishable from a real photograph. The process includes 3D modeling, the application of materials and textures, lighting, and post-production.

What is the difference between a 2D rendering and a 3D rendering?

A 2D rendering is a static two-dimensional representation, similar to a floor plan or flat illustration. A 3D rendering provides a realistic three-dimensional visualization of the project, featuring depth, perspective, lighting, and materials that simulate reality. 3D renderings allow for a much more detailed understanding of the structure, finishes, and spatial experience of the architectural design.

What types of architectural renderings are there?

The main types of architectural renderings are: interior renderings (photorealistic images of interior spaces such as living rooms, kitchens, or bedrooms), exterior renderings (visualizations of the building’s facade and surroundings), 360-degree virtual tours (interactive tours where the user can freely navigate the space), 3D animations (videos that allow users to explore the project in motion), 3D floor plans (three-dimensional representations of the floor plan), and product renderings (visualizations of individual objects such as furniture or accessories).

What is the purpose of a rendering in the real estate industry?

In the real estate sector, renderings are used to market off-plan properties before construction begins, attract investors by showcasing the project’s final result, validate design decisions before construction starts, create high-impact marketing materials, and accelerate the sales process. Based on Lobo Studio’s experience with over 3,700 clients, the sales process for new construction is reduced from 12 to 7 months on average when professional renderings are used.

How do you create an architectural rendering?

The process of creating an architectural rendering consists of several phases: first, the project’s volumetry and scenes are created based on the exact measurements from the blueprints. Next, the camera is positioned to select the best viewpoints. Next, materials, textures, and decorative elements are applied to bring the scene to life. Then the lighting is configured to simulate realistic lighting conditions. Finally, the image is rendered in high resolution and post-processed in an editing program to achieve maximum photorealism.

How much does it cost to create a professional rendering?

The cost of a professional rendering varies depending on the complexity of the project, the type of image, and the level of detail required. In Spain, a high-quality interior rendering can range from €250 to €1,500 per image. The price depends on factors such as the size of the space to be modeled, the level of interior finishes, the quality of the rendering, and the software used. The cost should be viewed as an investment in marketing, as high-quality renderings significantly increase the perceived value and speed of sale for real estate projects.

Can a rendering be mistaken for a real photograph?

Yes. Today’s photorealistic or hyperrealistic renders achieve a level of detail in materials, lighting, and textures that can be virtually indistinguishable from a real photograph. This is achieved using specialized 3D modeling and rendering software, combined with advanced global illumination techniques and professional post-production. In the case of high-end renders, even industry professionals may have difficulty distinguishing them from photographs.
