Currently, one of the best ways for the modern architectural visualization field is 3D Rendering. The main target for visual designers in the field of architecture is to generate a more photo-realistic image design. The 3D rendering process allows you to do this job. For entrepreneurs and designers, 3D rendering is currently the standard for architectural visualizing prototypes.
As for application purpose, we can show the example of architectural rendering which is very popular among real estate. Moreover, nowadays designers use 3D rendering for the interior rendering of homes, rooms, and spaces. Sometimes, in product renderings, 3D rendering is also used. Are you more curious to learn a brief on “What is 3D Rendering?”. Let’s have a discussion.
What is 3D Rendering?
3D rendering refers to a three-dimensional computer graphics design procedure by converting 3D graphical models into more simple 2D images. This process can include different types of styles and effects. Currently, both the photorealistic effects and non-photorealistic effects are popular as 3D rendering styles. Visualizations likewise 3D floorplans, product rendering, interior rendering, architectural rendering, as well as virtual reality all, can be done through the 3D rendering process.
Generally, 3D rendering is the adoption of a graphical object in the form of an illustration for example 2D image. Both the artistic and technical designers use 3D software for 3D rendering purposes. This software generates images to provide a detailed explanation of the concepts and designs. Technical drawings or CAD drawings are used commonly for the purpose of 3D model creation.
Other realistic design features such as lights, shadows, optical illustration, colors, textures, atmospheric effects are added after the creation of the 3D model. In the final stage, ‘Rendering’ also known as visualization or illustration is implemented. Here, computer-aided 3D software calculates all detailed inputs to generate a 2D image. These 2D images can be used for both conceptual or advertising purposes. A single 2D image can be used for rendering. Otherwise, multiple 2D images can be stitched all together to generate an animation or real-time visualization.
When 3D rendering is performed implementing the real-time method, the main focus is to create the 3D models into 2D images, in addition to a more detailed 3D photo-realistic effect. In contrast to the non-photorealistic rendering, the main difference for the realistic or real-time 3D rendering is the image processing and calculation speed.
In cases of most interactive graphics or computer video games, real-time rendering is generally very common. Here, to show the images like a movie scene, the 3D images are continuously processed and calculated at a greater speed. In general, interactivity and speed are the main things in real-time rendering. The speed of the movement should be adjusted in such a way that our human eye can easily perceive in a realistic and natural way.
From the brief study and research on the internet, it is found that the minimum rendering speed is typically 24 frames/second to gain the highest acceptance rate of photorealism. This is the minimum rate for a human eye to perceive the natural movement or real-time illusion. Real-time rendering is mainly performed by computerized modern software that can perform millions of complex calculations within the blink of the eye. This software also supports you with some common and easy parameters for designing, working, and understanding purpose. In a few modern interactive 3D gaming engines, real-time rendering engines are implemented to provide you some stunning graphics.
How Does 3D Rendering Work: Few steps of the process
There are some convenient steps for converting your 3D model to 2D images. Those 3D rendering steps are in some order but those orders are not necessary to follow step by step. It varies on the project requirements and you may require fewer steps or can jump between steps. The steps of 3D rendering work are followed by:
- Visualize the Project
When you are building your model, you should have a clear idea of the project. You can make proper planning, pencil sketching, and can match with the reference image of your project to visualize the overall project on your head.
- Creation of 3D Model
In this step, you can use computer-aided software that is specialized in 3D drawing and modeling. You can build a basic 3D physical model of your structure.
- Setting up Materials and Basic Texturing
In this step, the main focus is to build the 3D model to look as much real as you can. You can set up the materials control to portray something matte or glossy. You can also decide or modify the structure of the surfaces (ex: make the surface rough or smooth) and also can vary different parameters of the software you have used.
- Setting up Lights
To create your illusion similar to the natural environment or real-world, you can adjust up the lighting requirement in your 3D scenario in the software.
- Create an Initial Rendering
If you have already completed the steps above, then you can create a rendering of your model by generating a 2D image using the software. The time required to complete this step depends on the desired quality and complexity requirement of the designed model.
- Update the Requirement by Refining
If you find any fault in your project or you are working for any clients, then to achieve the desired design and result you have to do several revisions according to the demand. During each revision, the updated process drafts are presented to the customers for their valuable feedback.
- Delivering the Final 2D Images
If the requirement and demands are fulfilled, then the finalized 2D image or multiple images are delivered to the customers and clients. According to the required demand of the 2D images, the appropriate resolution and size, desired file format is maintained.
After a brief understanding of ‘What is 3D rendering’ are you ready to dive into the types, benefits, and software used in 3D rendering. Let’s go deeper.
Types of 3D Rendering
- Real-time Rendering
It is a process of rendering that occurs in a real-time process. This process is generally an interactive rendering process that happens right before your eyes.
- Offline Pre-rendering
Few types of 3D models are very difficult to be rendered in real-time due to their complexity and well-detailed process. This type of rendering requires a huge amount of processing power and can require several hours to finish. As each image or frame needs to be rendered in a complex way, they can be only viewed after the full rendering process is completed.
In this process, rendering is performed to decide the visible items within a frame. Here, we can simply place the objects within the particular scene with a higher rate of accuracy.
- Ray Casting
This rendering technique is quite an old technique used in 3D games of initial days and flight simulators games. Here, an intersection test is performed where we can determine the relative position of all objects.
Besides those 3D rendering techniques, there are few more techniques likewise Radiosity, Wireframe, and Scanline Rendering.
Major Benefits of 3D Rendering
So far, we have learned and understood the process of 3D rendering. Now, we should know the importance of 3D rendering in architecture. Let us give an insight on below:
- Enhanced the Processing Time
3D rendering of any architectural visualization or interior setup design requires less time compared to the traditional interior photoshoot. Only with the support of a computer, a designer can instantly design the desired 3D model. It is so flexible and less time-consuming procedure.
- More Cost-Efficient
Traditional sketching of an architectural model is generally quite expensive. You require different types of pens and pencils and art paper for quality design. This process not only requires your money but also consumes your valuable time. So, compared to this cost, designing 3D rendering using computer software is more cost-effective. You do not need to spend a portion of your valuable money on those pens and papers.
- Working Flexibility and Efficiency
In the case of a traditional business photoshoot of your architectural design, you do not only require a photographer. But you have to find space for the working environment, pay rent for space and studio. It also requires proper set up which not only increases the bills of your business but also a lengthy and complex process. With the support of 3D rendering, you can just use 3D rendering software on your computer and start working more flexibly and efficiently.
- Enhances the Creativity
The traditional physical designing process has many limitations. You cannot use whatever material do you want. Moreover, you have space limitation, time limitation as well as much scientific viability. 3D rendering supports you to remove those restraints. Using 3D designing software, you can access the software library and can design any type of immense and complex structure using your creativity. You can use different types of structural elements, can have huge space, and also use material texture through the software library. In this way, you can be familiar with many precious materials and also enhance your creativity.
- Simple to Use and Edit
3D rendering is quite simple if you are familiar with the software and have some architectural designing knowledge. You can edit and removes items if you find any fault in your design. You can also copy and re-creates any items as well as it will save your time. You do not need to completely redraw the design or erase any part of the drawings like in the traditional process. So 3D rendering process is very convenient and simple to do.
3D Rendering Software
One of the most important tools for 3D rendering work is 3D rendering software. There are different dedicated software companies worldwide that are working for developing and updating 3D design software. Generally, a 3D rendering software proceeds with a previously designed 3D model and consistently transforms the model into a newly generated realistic 3D image or environment. With the support of those newly realized 3D solutions, real-estates, developers, and graphic designers can implement new objects and characters for the real-life build-up process.
Designers can use many features likewise scaling, navigating, and interacting with the computer-generated 3D rendered images. Moreover, many 3D rendering software supports or combines with animation software. So animation design can be also performed using this 3D rendering software. Many 3D rendering software also has exclusive features such as lighting and texturing. So natural and realistic features in the image can be integrated by adding depth in those image frames.
Some more exclusive software features include rendering setup, animation tools, physical camera, surface modeling, motion paths, etc. Currently, ongoing trends and features around the world such as side-cut perspectives and 3D printing are also supported by a few 3D rendering software. Visual artists and designers including architecture, advertising, automobile, animators, etc. can create a natural and real-time illustration using that 3D rendering software.
Currently, some top-rated 3D rendering software companies are Enscape, Adobe Dimension, 3ds Max Design, SolidWorks Visualize Boost, KeyShot, Direct3D, Maya, BLENDER, 3D CRAFTER, OctaneRender, FREECAD, SKETCHUP, etc. So, why should we use 3D rendering software for 3D rendering as well as architectural visualization purposes? What are the key benefits? We are now going to give some thoughts below:
- Designers can easily insert precise and accurate measurements of their 3D rendering model
- Designers can measure their 3D model from all angle
- Designers can conveniently make any kind of visualize change or edit the design process
- Designers can make visual communication with their clients easily and customize the model according to their demand
- For architectural visualization purpose, it is handier to distribute the design to the client with 3D rendering software compared to traditional paper design
Now that you have a full idea of ‘What is 3D rendering’. For architectural design and visualization purposes, the 3D rendering process is the future for all associates such as designers, architects, clients, real-estate businessmen related to the architectural and build-up construction field. 3D rendering has brought huge innovation, creativity, and most importantly mutual communication and idea-sharing globally for the upcoming journey.
