3D rendering is nothing but the procedure of creating an image with the help of computer software. It involves modeling the building; setting up of materials like brick, concrete and glass; applying lighting and some post-production. In the field of architecture, 3D rendering is used for generating photo-realistic images of structures that to be constructed.
3D Rendering and Its Common Applications
3D rendering involves the effective use of 3D software programs for creating images that give the viewer a better advertising or explanation of designs and concepts. 3D models are usually created with the use of different technical drawings and even CAD designs. Once a 3D model is built, the artists move on to adjusting camera angles, lighting and textures.
The last step of this is called rendering where 3D software is used for computing all the different inputs for three-dimensional images. The images thus created can further be used as a single image. Common applications of the process of 3D rendering are architectural renderings of properties, commercial buildings, construction sites, product renderings, interior renderings and so on.
3D rendering is also used as the standard in the visualization of prototypes for the entrepreneurs. This is a highly flexible procedure which means it is quite possible for the users to create 3D renders of just about anything that is imaginable.
Steps Included in the 3D Rendering Procedure
There are different steps included in the 3D rendering procedure and they are as follows:
- Understanding the Vision of the Client
3D artists should have a clear understanding of the project at hand if they really want to build the best of models. The 3D artists start visualizing construction projects in their minds using the reference images, sketches and site plans provided by their clients. The camera angles are agreed upon at this point based on 3-dimensional plans.
- 3D Modeling
The next step for 3D artists involves using specialized 3D modeling programs and tools for creating digital models. This step is quite similar to creating the model of a physical structure except that the structural exists virtually and not physically.
- Texturing and Materials
The next step is where 3D artists apply textures to all the 3D models for making them appear original or realistic. This phase is quite similar to drawing a physical structure or pasting images and materials on to it. In majority of the cases, this step also involves material setup. It means the settings controlling things that are glossy or matte. 3D Artists in this stage have the flexibility of changing surface roughness and various other significant parameters based on the software that is being used for the process.
Lights are set up in 3D scene and in a way that they stand as a copy of the real-world lighting conditions. This is the same as setting up lighting conditions prior to shooting a video footage. 3D artists will find the best way to convey the design.
Rendering is the process where the computer is used for generating 3D images from the scenes that have already been created with the steps mentioned above. It usually takes time from a couple of hours to 20 hours, depending on the size and complexity of the image.
At last, post-production will guarantee the minor adjustment after rendering process, at the same time, adding people or cars is included in this procedure.
3D rendering has come as a boon for architects and designers who find it difficult to give a clear picture of their design and concepts to the clients. The use of this process has helped professionals in garnering more projects and in making good fame at the same time.
