What is 3D Rendering
3D Rendering is the use of technology to digitally create images and videos that represent or advertise concepts and designs. In technical terms it is a two-dimensional representation of a computer-generated wireframe model, that has been given properties such as texture, color and material.
Most commonly, a technical drawing or CAD design is used to create a 3D Model before the properties are added with the use of lights and camera positioning to create a realistic perception. In correct terms ‘Rendering’ is the final process where the 3D software computes all of the inputs to create the final image. Don’t let that confuse you however. At 3D Revolution, we can help with all parts of the process from start to finish.
Uses for 3D Rendering
3D Renders can be created as a single image, stitched together into an animation or created as a realtime video with the same software that is used to create video games.
There are countless reasons to use 3D Rendering...In fact, you probably see 3D Renders every day without realising it on the television, in advertisements and magazine covers. You may be surprised to hear that most product advertisements were, at least to some degree, created digitally with the use of 3D Rendering.
With recent advances in computer technology, 3D Rendering has become more efficient, affordable and effective, as the ability to create images and video that is hyper-realistic becomes available.
Currently, 3D Rendering is used mainly for:
Movies
Medical Imaging
Safety Training
Environment Simulations
Product Prototyping
Engineering
Video Games
How 3D Rendering Works For Architectural Rendering
3D Modelling
The first step in the 3D Render process is to create a 3D Model. 3D Artists use specialised 3D Modeling software to create a wire-frame model using building plans or existing digital designs. This is similar to building the frame of a house digitally.
Materials, Texturing & Environment.
The 3D Artist applies materials, textures and colors to all surfaces to make it look as realistic as possible. This is everything from selecting the color of paint on a wall to the texture of water for an in-ground pool. Additionally, at this point, the designer will add furniture or extras such as plants, cars and even people.
Lighting
The 3D artist sets up lights in the 3D scene to replicate real-world lighting. This process is similar to 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
Rendering is the final step and is when the computer generates the 2D image or video from the scene created in the stages above. It is just like taking a photo in real life.
Unlike taking a photo however, rendering can take any were from a few hours to a few days per image. This is dependent on the complexity of the scene and the output quality desired. In fact, for more complex renders, the use of multiple computers is needed for the process.
