ASTRAL INSTITUTE OF DESIGN offers the best 3D RENDERING classes in India. 3D RENDERING is not a difficult course, but you will need good coaching to understand the concepts better and get valuable guidance. And ASTRAL INSTITUTE OF DESIGN is one such 3D RENDERING Institute that understands the needs of the students.  

A simple overview of the process is as follows: 

  1. A 3D artist models the scene. 
  1. Materials are set up (glass, concrete, brick etc.). 
  1. The lighting is set up. 
  1. The image is computed (render the image). 

In architecture, the goal is to generate a photo-realistic image like the example below. Check out our blog post on Architectural Rendering. 


3D rendering refers to adapting the likeness of an object in the form of an image. 3D rendering—both technical and artistic—employs the use of 3D software to help create images to help better explain or advertise concepts and designs. The use of technical drawings or CAD designs is common in the creation of 3D models. After creating the 3D model, the 3D artist adds lights, textures, and cameras. The last step in the process referred to as “Rendering” is where the 3D software computes all inputs to create a two-dimensional image. These images can be used as a single image still rendering, stitched together into an animation, or created on-the-fly in Realtime programs such as video games. 

Some of the more common applications of 3D rendering include; architectural renderings of real estate, interior renderings of rooms and spaces, and product renderings. 3D Renderings are also standard in visualizing prototypes for entrepreneurs. 3D modelling and rendering are highly flexible, so it is possible to create a 3D render of about anything imaginable. 


The method below describes the 3D rendering of 2D images. Although the process is broken down into steps, a 3D artist does not always follow this order and may jump between processes. For example, understanding the client’s vision is a continual task throughout a project. 


To build a model, a 3D artist needs to understand the project. Using plans, sketches, and reference images provided by the client, a 3D artist starts by visualizing the project in his or her head. From this point, camera angles are typically agreed upon based on the 2-dimensional plans. 


The 3D artist uses specialized 3D modeling software to create a digital model. This phase is analogous to building the structure of a physical model, except that the model only exists digitally. Check out this list of free 3d modeling software. 


The 3D artist applies images to the 3D models to make them look as realistic as possible. This step is analogous to painting a physical model or gluing materials and photographs onto it. In most cases, there is also material setup. This refers to the settings that control if something is matte or glossy. The artist can also modify the roughness of surfaces and many other parameters depending on the software used.  


The 3D artist sets up lights in the 3D scene to replicate real-world lighting. This process is like the way a photographer or videographer would set up lighting before shooting with the addition that the 3D artist needs to setup the sunlight and or ambient room lighting. 


Rendering is when the computer generates the 2D image or images from the scene created in the steps above. It is analogous to taking a photo in the physical world. 

Rendering can take anywhere from a fraction of a second to several days. Rendering time depends on the complexity of the scene and the quality desired. This process is completed solely by the computer. In some cases, images are rendered on large clusters of computers called render farms. 

Step 6: Refining 

During the refining, process drafts are provided to the client for feedback, usually in a low-resolution format to speed up the revision process. 

The artist makes the requested revisions to the scene, textures, and lights until the desired results are achieved. Changes can be made independently: for example, most changes to the model do not require the texturing to be updated. 


The agreed-upon final 2D image or images are provided to the client. Depending on the desired resolution, the images will be provided in a specific format to support and size. For web, images are optimized medium size jpg, while for print images are high-resolution raw files.  


Now that you better understand the rendering process, let us get to the fun part: What can rendering do for you? 

You can 3D Render about anything. Rendering is economical and convenient. 3D renders allow you to view your design long before construction or manufacturing, so it facilitates refinement and better overall design. 

Through animation, you can highlight complex simulations! Today’s 3D modeling software has physic engines to simulate forces on materials. These simulations can show a structure under stress or a boat bouncing through waves. The flow of people through buildings can be simulated to find out the most efficient arrangement of rooms or exits, and products accurately shown in use in the desired environment. 

Clients can also choose to be marketing pioneers and opt for unique 3D rendering applications. Virtual reality is something many developers and marketers are experimenting with within their showrooms and websites. Rendering allows for a more dynamic experience for customers. Also, the rise of 3D printing makes 3D models more practical, as your design can on display in the real world. 3D printing allows developers to have both 3D images and Animations along with a physical model for their showroom all from one supplier.  

Below is a list of a few of the most common industries 3D rendering is being used:
