Different Types of Rendering: A brief guide on types of rendering

Architectural rendering is a modern visualizing art of forming detailed three-dimensional images or creating 3D animations showing different attributes and characteristics of an architectural project design. Generally, 3D rendering is the adoption of a graphical object in the form of an illustration, for example, a 2D image. This process can include different types of styles and effects. Moreover, those rendering images can provide a detailed explanation of the concepts and designs.

We can classify rendering into many different categories based on its characteristics. In general, few groups are categorized based on rendering techniques. On the other hand, in architectural rendering, the classes are based on architectural visualization purposes. Are you a bit curious to know about different types of rendering? Let’s dive deep into it.

Types of Rendering in Architecture

Based on the goals and requirements, there are different types of 3D architectural rendering trends currently ongoing. Among them, we can summarize as follows:

  • Exterior 3D Rendering
  • Interior Rendering
  • Aerial Rendering
  • Floor Plan Rendering
    3D Animation Rendering
  • CG Panoramas Rendering
  • Virtual Tours Rendering

Those are the currently ongoing architectural 3D rendering trends for design and visualizing different architectural projects. Now, you should know in detail about each rendering in architecture.

Exterior 3D Rendering

This type of rendering is the most widely used architectural rendering in this sector. By designing 3D photo-realistic images of the exterior of your project, you can show the best visualization to your potential clients or investors. In the real estate business and architectural construction industries, they use exterior rendering commercially.

To gather funding for the approval of your architectural projects, exterior rendering or visualization model design is such an essential task for designers. External rendering acts as a melting point for investors, business people, designers, and contractors related to the construction. It allows understanding, design, and plan for the construction site in the most efficient manner.

Moreover, designing a 3D photo-realistic exterior image allows you to impress your potential clients by implementing texturing, lighting, etc. Clients can visualize their potential projects, buildings, and homes in their own eyes for their pleasure. So, exterior rendering is reasonably necessary for mutual trust, relationship, commitment, and mutual communication among the clients and service providers.

Interior Rendering

Interior rendering is sometimes equally crucial as exterior rendering. Interior visualization is essential in construction industries for advertisement and promotion purposes. Interior rendering is the most eye-catching from a potential customer’s point of view. They can visualize the 3D design of their possible bedroom, living room, drawing room, etc., to experience the style, lighting, spaces before starting the actual construction.

Moreover, the photo-realistic design of interior rendering allows potential clients to experience the livability, real-life feel, and spaciousness of their future home. The designers consider all detailed aspects of their interior design, including the atmosphere, lighting, layout, textures, style, and other reasonable details. Those details and photo-realistic quality of interior design allow the clients to consider their decision before buying.

Aerial Rendering

Aerial rendering is a modern trend in architectural industries. This is a unique type of rendering where the projects, structures, and buildings are visualized from the above and outside. The viewing angle is looking down at a particular angle that provides a unique experience.

In this type of rendering, designers give more priority to the outdoor and surrounding environment compared to the general 3D exterior rendering. Aerial rendering is so essential from the urban planning perspective. Designers can visualize the idea to fit their project into the city’s present design. Aerial viewing from above also provides the architect to select the appropriate orientation of their model and landscape features.

Floor Plan Rendering

From the very beginning of architectural rendering, floor plan visualization is the most traditional and general concept. To attract potential customers, real estate companies create a catalog of a traditional 2D floor plan of their buildings so that the clients can have an outlook of the size of the home spaces and orientation.

Currently, a more modern 3D floor plan is going as a trend worldwide. This type of rendering includes additional depth and greater details that are necessary for promotional and marketing purposes to attract clients. Here, clients can easily visualize themselves in person as well as their furniture in the designed home space to experience a more realistic feel.

3D Animation Rendering

This type of rendering is the most eye-catching and interesting visualization technique for both designers and clients. 3D animation rendering is similar to watch a short film in which the architectural visualization of the detailed design and modeling of the project is the major plot. This is much more than the 3D still image design.

Here, different scenes implemented in the 3D animation can provide a detailed visualization where not the tiniest bit of details is missing. 3D animation rendering deploys all the 360-degree angles and details of the space. Clients can visualize the depth of the projected space. Moreover, clients can overview their own eyes in detail before buying their projects and buildings. Even by visualizing the 3D animation, clients can request to the designers any requirements or change needed and also update the design plan.

As 3D animation covers all details, textures, features, aspect ratio, every angle, and space of the project, it ensures the best quality to the clients. From the professional point of view, architectural professionals and artists can implement many unique features, likewise the addition of logo, text, background music, and addition of professional voiceover to enhance the quality of the animation to attract more clients.

CG Panoramas Rendering

CG panoramas are currently a modern and interactive way of architectural rendering. Here, an interactive realistic 360- degree angle view is supported in real-time. People can experience details similar to real life, where all aspects of space are shown throughout a panoramic view. All the investors, as well as the customers, can explore the spaces and places, can feel the real-time effect, and every detail also can walk freely through space.

The customers can come to a decision to buy their projects by experiencing all the details. CG panoramas rendering is a little bit more complex as it requires much time and effort as requirements compared to general photo-realistic still image. In CG panoramas, you need to transform images of 2D panoramas to a 3D visualization. The processing time of this visualization is two or three times more compared to the regular rendering.

The overall outcome of CG panorama gives you the highest satisfaction and impressive experience. It is generally aimed at convincing customers to buy the architectural design, ensuring the highest quality and efforts.

Virtual Tours Rendering

When it comes to commercial perspective, the most efficient way to convince clients is to take on virtual tour rendering. Experts and professionals in the architectural field disclose that virtual tours provide the highest immersive experience compared to all other architectural 3D rendering techniques.

In those virtual tours, generally, a number of panoramic photos are sequenced in the form of a short film that includes realistic sounds and texts. Nowadays, architecture design and real estate companies offer this incredibly exclusive 3D rendering service. The clients go on a virtual tour to experience the details and space before the construction.

This is also essential in the construction process to get rid of making errors and mistakes in the buildup stages to save your precious money, time, and effort. On the other hand, virtual tours can provide the scope for new adjustments, changes, and modifications according to the client’s demands and requirements. The realism and incredible details of virtual tour rendering can offer the architect to be successful in commercial purposes by attracting customers.

After coming to this point, we have learned many things about types of rendering, especially in the architecture field. But there is a bit more to learn about the overall types of rendering and techniques. Are you getting a bit more excited! Let’s go!

2 Main Types of Rendering

In general, there are two types of renderings. They are based on their computation speed and finalization speed. They are:

Real-time Rendering

Most commonly, in computer gaming and in different interactive graphics, real-time rendering is generally implemented. Here, the images are processed and calculated from the 3D images and information at an extremely higher speed. By establishing a rapid image processing technique through graphics hardware, the performance of real-time rendering is ensured.

Offline Rendering

In some rendering cases where the processing speed requirement is lower, the offline rendering technique is often implemented. Generally, in visual effect work, offline rendering is applied due to the highest standard photorealism requirement. In comparison to real-time rendering, no unpredictability is found in offline rendering.

Types of Rendering Techniques

There are few widely used interactive visualization techniques currently ongoing in construction, buildup, as well as architecture process. Those techniques are so efficient for working purposes, analysis, designing, and management. Few visualization techniques are followed as:

  • Radiosity Technique
  • Ray Casting Technique
  • Scan-line Technique
  • Ray Tracing Technique
  • Z-Buffer Technique

Let’s summarize those rendering techniques below.

Radiosity Technique

Radiosity is an image-precision technique that enhances the photo-realistic effect and quality of any image. By integrating this technique, the images become more realistic with the support of inter-reflection between objects. It is done by a natural physical phenomenon. In the radiosity technique, it stimulates the light at the light source, and propagation is progressed as diffusion propagation. Then, the information is carried by the re-radiated light on the object.

Ray Casting Technique

Ray casting technique is an image-precision mechanism. In this technique, the mechanism detects all the visible surfaces. Here, a projection center is referred to during the process. A regular grid is also established where a screen is designed in an arbitrary position. The general concept of ray casting is similar to the rays from the eye.

Here, rays from the eye are compared to one per pixel. They always try to identify the closest object which blocks their path. The main advantage of this method is the opportunity to simply manage non-flat surfaces, likewise spheres and cones.

Scan-line Technique

The scan-line technique is an age-old technique for visualization. The image precision algorithm is based on the blending process. Here, the determination of the visible surfaces is performed by identifying the reported shadows. In this process, the scan line controls the intervals of detectable pixels for each and every scan-lines.

Ray Tracing Technique

Ray tracing rendering is a technique in which it can generate immensely naturalistic lighting effects. This technique can generate realistic shadows and reflections. Moreover, it supports much-more efficient scattering and translucence integrating different lighting phenomena, likewise lighting refraction and lighting reflection.

The algorithm is set in such a way that it can easily trace and follow the path of light. After then, it stimulates the path where the light interconnects with the virtual objects and then finally hits the computer. Compared to other rendering techniques, the ray-tracing method has gained increasing popularity in the realistic simulation of light.

Z-Buffer Technique

Z-Buffer technique is an elementary algorithm for detecting visible surfaces. Here, two data structures are commonly used, known as Z-buffer and frame-buffer. Z-buffer is a memory area where the z coordinate is kept nearest to the observation point for every pixel. On the other hand, the frame-buffer carries the color information associated with the pixels inside the Z-buffer.
Finally, after reading this informative article, you now have a clear view of types of rendering. According to your demand, requirement, advantages, and disadvantages, you can select the best rendering technique available for you. In the architectural field, you have so many options. So you have to customize your budget, time, and effort.

Most importantly, we will learn, share our ideas and thought together, and build up our future through this journey.
