AVR / Verified Views
Verified views, Accurate Visual Representations (AVRs) or Verified View Montages (VVMs) are based upon a more accurate architectural photomontage. One of the key differences between a photomontage and a verified view is the use of accurate camera positions, survey site data, GPS coordinates and a recorded methodology report of the process. This type of CGI is ideal to aid with a planning application or for clients to understand how the proposed build will affect the surrounding area.
Verified views are broken down into four different categories. These vary in detail and realism but all provide a valuable tool in understanding how the proposed build will look within the environment.
AVR Level 0: an outline of the building is shown depicting the size and location of the proposal.
AVR Level 1: a wireframe outline of the 3D model shows the size, location and visibility of the proposal.
AVR Level 2: a single overriding material CGI of the 3D model is produced depicting the lighting and massing of the proposal.
AVR Level 3: a high resolution CGI with the proposed materials and other 3D assets applied.
The first stage of creating a verified view CGI is to visit the chosen site to assess the best possible camera positions to capture the effect of the building in relation to the surrounding environment. Quite often camera positions are chosen by planning officers in order to best support the planning application but this all dependant on the project brief. Once the photographs have been agreed upon with the client, then using the site survey and accurate camera GPS matching we merge the 3D model into the photograph.
Using existing site photographs we are able to match the same environment lighting shown within the photography in 3D. This allows the 3D model to sit naturally within the photograph creating a seamless photorealistic photomontage. Our in house render farm can quickly produce a high resolution render of the building ready to be merged seamlessly into the site photography.
For each verified view the lighting on the 3D model is accurately matched to the site photography using GPS data and the suns position. This allows the building to blend seamlessly into the photography. Once the lighting is correctly aligned, then the image is rendered out in high resolution ready for any post production work needed.
Once the high resolution render of the building is created, it is then down to incorporating the render into the site photograph. Accurate masking is applied to integrate the CGI into the photograph and colour, saturation and hues are all refined to make the CGI come alive. People and further 3D elements can be added to the finished 3D visualisation to add realism and context.
At the end of the verified view process, a methodology document is supplied along with the high resolution CGIs. This document explains the process of how the verified views were created, the location of the site photographs, camera data, reference points and before and after images showing the impact of the building on the environment.
