Residential architectural renderings have far more advantages than just impressing clients and influencing sales. Models developed through 3D rendering services increase the efficiency of the construction process, help reduce the design cycle and help eliminate errors before construction begins. The 3D architectural visualisation provided by the rendering process is a significant step in architectural and engineering work, but due to its technical nature, outsourcing is seen to be increasingly favoured by Western firms to procure architectural rendering services at a profitable cost and of high quality.

Rendering is a great tool to visualise Renderers Sydney and perfect the architectural process, but just what does it involve? In brief, a detailed representation of a 3D object results in 3D modelling. This 3D model (or scene file) can then be used as an image on a print through the process known as rendering. It is also known as image synthesis and is the digital development of a photorealistic image from a 2D or 3D model. It is called a ‘rendering’ most likely because it is similar to an artist’s ‘rendering’ of a scene. The created scene file hosts objects in a defined language. This file contains data on geometry, viewpoint, texture, lighting, and shading, which is transferred to a rendering programme. The data is processed, and the output is sent to a digital image or raster graphics image file.

A rendering device, a graphics processing unit or GPU, assists a CPU perform complex rendering calculations. Models are specific mathematical 3D representations of points and surfaces, or vertices and polygons, and a 3D software render engine transforms the equation to a complete and detailed 2D image. Spatial, textural and lighting data combine to create colour values for each pixel of the 2D image. For example, when using virtual lighting to make a scene look realistic, the rendering software used should effectively solve the rendering equation. This equation does not determine all light sources and effects, but it is a general lighting model for the image generated. Rendering provides the finishing touches to models, and rendering software is an engineered programme that brings together disciplines connected with light physics, visual perception and mathematics.

Current 3D software includes a render engine and textural and lighting packages to enable the creation of photorealistic images. Commonly used render engines are Mental Ray and V-Ray. Available with Autodesk Maya, Mental Ray is fast and flexible, using raytracing and global illumination, to generate images with subsurface scattering. V-Ray is used with 3DS Max for detailed architectural visualisation and environment rendering. It is well known for its lighting tools and well-stocked materials library. Residential rendering includes architectural renderings of homes and buildings, interior design renders of rooms and homes.
