3d Scanning for Game Development and CGI

3D Scanning for Games Developers and CGI If a picture paints a thousand words... A growing market for our services is the gaming industry, the imagination and creativity that goes into these products is staggering and it is wonderful to be a part of this vibrant industry. There is no doubt that providing the data required for a game or CGI backdrop is time-consuming and can be expensive, but the requirement of these industries is often for the best quality that can be obtained.  Now there are no ‘standards’ for this, it is creative and therefore largely subjective as to what is meant by quality. Many recent enquiries want as much data as possible: fine point clouds, detailed meshes and the most photo-realistic of textures. Those more seasoned in this arena, will know that ‘more’ is not necessarily ‘better’ and many clients reduce their quality requirements as we burn-out their computers with huge data files. However, we capture as much data as possible in the field simply because we can choose not to use it when we get home, we can’t use data we haven’t got.  Fully meshed and textured 3D model of a ruined chapel. 0 Points collected during our last project ... a 3d scan is like being on location A recent project in South-East Asia captured over 8 billion points of data and almost 8000 photos; I doubt we have used a tenth of this to create the required models. Clients have required us to provide material for caves, buildings, landscapes, cliffs, deserts and forests, we specialise in getting to remote places. Although LiDAR scanning allows us to collect data from a safe distance, you can’t beat getting close to the subject for the best results, so we are often dangling from ropes, climbing cliffs, in and off boats or simply ‘yomping’ up a mountain. This also results in more data. We have found, therefore that most jobs require less data than the client believes is necessary – however, the quality of imagery required to create the desired model keeps growing. The process known as texturing is crucial to the quality of the output. How can Commendium help? Commendium use very precise LiDAR scanners and photogrammetric hardware to produce highly accurate 3D models. These models can be exported into any manner of file formats, fully textured if needed. For texturing, we create 2D and 3D textures suitable…

Drone Filming Techniques and Tips

Commendium have used the following drone filming techniques for a number of different projects, from archaeological purposes to record the setting of a site, to documentary footage for television. Each of the projects we use the drone for will require different techniques and outputs. One of the best tips for any drone filming is to keep it simple. Don't move the camera too much and if it needs to move, do it slowly. Planning shots or flightpaths in advance will improve efficiency, which for drone filming is essential. Generally, flight times of between 20 and 40 minutes are achievable, so maximising your actual recording time in the air. When planning your flights, Google Earth is your friend, being able to see the sites in rudimentary 3D is very useful to gain an idea of the layout of the land and even to draw paths of where you expect to fly. Other very useful websites to check are http://www.noflydrones.co.uk/ in order to see where there are airspace restrictions and https://notaminfo.com for any NOTAMs during your flight period. Different Filming Techniques As Commendium carry out different projects, here are some tips for the type of flights: Archaeological Setting and Recording Try and fly in a straight line, keeping the horizon in the shot in order to get an overview of the surroundings. Orbit shots can be used to focus on particular elements. Height of the flight is important - you need to be able to capture the locality as well as the main elements of the archaeological area. Make sure you fly high or low enough to capture these - may take a couple of runs to get it right. Photogrammetry  This is one of those specialised drone filming techniques that requires you to capture photos with a certain amount of overlap, generally in a defined series, with the right colour balance. There are some apps to help you do this, notably Drone Deploy (www.dronedeploy.com) and Pix4d. These types of flights require a certain, consistent altitude in a manner that gets the best overlap between photos. It can be done manually using a 5-second time gap between photos. The difficulty arises when you start having large terrain elevation changes in the area (such as a valley and a fell). Broadcast Film This is probably the most difficult technique to gain - videography skills are needed as well as flight skills. Sometimes you…
