Outsourcing Residential Rendering
Rendering is a significant step in residential architecture and outsourcing architectural rendering services is increasingly favoured for greater profits while maintaining high quality.
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 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.
The more popular software tools used for architectural rendering include:
Photo-realistic visualisation and 3D architectural rendering can ensure that design ideas are viewed while maintaining the accuracy of the details portrayed. The effect of shadow, sunlight and artificial light can also be portrayed in renders. Effective 3D rendering communicates ideas clearly to clients, and with a process-driven approach, both clients and those providing 3D rendered images will benefit. This is how the process generally works:
Architectural rendering services for residences require investment in rendering software, hardware and the training of personnel. For firms that find this kind of investment challenging, an emerging solution enjoying popularity is outsourcing these services. Outsourcing 3D rendering services provides a cost benefit of up to 60% less than recruiting and training in-house teams.
Outsourced companies can convert freehand sketches and CAD drawings into 3D architectural renderings of high quality. Architects and graphic designers from these firms can develop 3D renderings in narrow time-frames.
Some of the benefits of outsourcing 3D rendering are:
To get optimum results when outsourcing retail rendering services, some common mistakes are:
Communication Lapses – With outsourced projects, timelines, guidelines and other project details need ongoing communication. A dedicated offshore team would help significantly in clear dialogue between the two firms. It is key to understand that renderers are not designers. Renderers need not be specifically aware of furniture, fittings, material, colour schemes and other details required for a complete and detailed design. This has to be communicated.
During the increasingly competitive climate in the construction industry worldwide, advantages such as outsourcing are favourably reflected in overall profits. While understanding the process of architectural rendering services is important, it is essential to employ clear communication at all times with outsourced firms on all project details for maximum results.
