From Photomontage to Videomontage!

New media does not stand still for long.

In order to support the move from photography to video in engagement and communication, Linknode are launching our unique TrueViewVisuals Videomontage service.

We know that in the future, immersive realities will have a significant impact on our lives, augmenting our world with information curated for us by Artificial Intelligence focused on interests, time and location.  Our professional tools for understanding change through planning are in for the journey, but for communication and sharing of plans and designs we realised we need to provide something more, something unique and engaging.

Our social communication is a benchmark for what is expected in 2017.  Twitter, Facebook and Instagram are increasingly video focused, supported by new standards in camera recording, broadband capacity and user expectations.

As a case study, earlier this month we took a road trip up to the North East of Scotland and captured some imagery of a planned project.

“The videomontages produced by TrueViewVisuals are not only innovative, but look stunning also. The HD video allows for a greater appreciation of a development site, giving new perspectives and a realism that cannot be paralleled with static photography.” 

Alasdair Warnock, Green Cat Renewables

This builds on our strengths and capabilities, tested and used for five years in landscape assessment.  Using real-world video as the basis of our production we can deliver more realistic, faster and easier to update video for use in public engagement, campaigns and sales.

If you have any queries regarding these new features, or you would like to chat further about how we can help create amazing videomontages, please give us a call on 0141 374 2741 or email hello@trueviewvisuals.com

#PlanTech and The Future of Planning

Last week was the inaugural PlanTech Week in London, hosted at the The Urban Innovation Centre, part of the Future Cities Catapult in Clerkenwell.

PlanTech

#PlanTech follows in the footsteps of #PropTech and #FinTech as the technology discussion arm of the planning & development community.  PlanTech, best described in the words of the FCC founders is “a showcase for the emerging technologies, innovations and visions that are transforming the way we plan our cities, towns and neighbourhoods“.

PlanTech_Week

As part of the PlanTech Future of Planning programme, Linknode were both at the Thursday evening Exhibition Launch and the Innovator Showcase.

What we Did

For those of you who have been following along, and a reminder for those new to the project, our work as part of the Future of Planning was in improving citizen and community engagement throughout the planning & development process.  We blogged about the project brief in March this year and delivered a

video from our ambitious working prototype as part of the project report.  A summary of our results is listed below.

  • Consumer mobile devices are capable of processing BIM data for on-street live visualisation using mixed-reality approaches
  • The highest quality videomontage production methods still require some offline processing and manual intervention
  • BIM integration provides rapid design review for professional assessment, but consumer access is more valuable when presented with rendered textured surfaces
  • The business models show space for commercial innovation in the sector
  • Our exciting next developments will take urban visualisation to a whole new level of engagement

Like our recent work in visual route assessment, the video is the most powerful form of delivery and communication.  The content below came from the application delivered for the project and shows BIM data for part of the Tottenham Court Road interchange redevelopment for The Elizabeth Line / Crossrail development in London.

Next Steps

For anyone interested in more detail relating to the results, to discuss opportunities for involvement and engagement in their own projects, or to work on future Future of Planning initiatives with us… please get in touch.

Conductor Line Sag in Grid Projects

One of the features we  added recently is drawing realistic looking Conductor lines between towers on our Grid projects.

Prior to VentusAR 5.4 we drew straight lines between the connector points on the tower models. This had the effect of fairly unrealistic looking conductor lines as even across the shortest distance the conductor lines sag slightly due to gravity.

This post shows some examples of the line sag development and adds some more detail on how the line sag is calculated.

Catenary Formula

The line sag formula we use when displaying the conductor lines on a transmission project is based on a generalisation of the catenary formula. To calculate the sag at a given point we use the following formula:

LineSag_Formula

Where:

  • a is half the distance between towers (in meters)
  • y is the drop at that point in the conductor (in meters)

Maths Example

Lets take a worked example, if the towers were 200m apart, then the variable a would be 100. We can calculate the value at three sample points:

  • at x = 0 the sag due is calculated as 0m – which would make sense – it is at the top of the tower
  • at x = 200 the sag is calculated as 0m – it also makes sense as it at the top of the other tower
  • at x= 100, the sag calculated is 10.033m – this is the bottom of the catenary curve

This is easiest shown with a graph. Below is a screenshot (with slight optical illusion):

LineSag_Graph

Visual Example

When drawing the line sag, we calculate thirty points along the wire and work out the sag between each of those points  – we then draw a series of straight lines between each point.  Our curve is actually a series straight lines between each of these points, but as you can see the visual impact is effective.

Line sag modelling has been added to all Grid projects that use conductor lines.

Limitations

This is only an approximation of how line sag works, I have asked an engineer how line sag is actually calculated and discovered it is far more complicated than I wanted to represent in a generic Visual Assessment tool like VentusAR.

This formula could cause conductor lines to be drawn underground – it is up to the person who set up the model to ensure that the span between towers is reasonable.  Custom modelling is, of course, available on any project where additional detail is required.

We live in a 3D world

Blog first published on Future Cities Catapult http://futurecities.catapult.org.uk/2017/03/27/blog-live-3d-world/ 

eventbrite-002-1600x800

We live in a multi-dimensional world and experience our environment through our senses. For most people, vision is the dominant way we experience the world. Our sense of orientation within a given context, location, and place is determined by an animated 3D model of the world that our brains construct from the cues around us. Light, materials, textures, and shapes all affect the emotional resonance that we feel within a place.

Without engaging communities and citizens in their own way of understanding world, we risk alienating and disenfranchising people by propagating fear, uncertainty and doubt (FUD). Instead we should empower citizens to be able to understand and make sense of development proposals and engage fully in the planning and placemaking process.

Linknode is working to solve this problem by developing a tool to make complex information about development proposals more accessible, relevant and understandable. In the modern world, accessible means mobile, device-centric, and personalised of data for on-demand information.

Accessibility also means being “location aware”.  In a desktop environment, a search engine can return results based on keywords, profiling and history, but search in a mobile context has the ability to enrich result with environmental context. For example, a search for the term “coffee shop” on a mobile device should return information about coffee shops in my immediate vicinity, not only a Wikipedia article about this history of coffee shops.

In order to make complex data about development proposals relevant and accessible, we need to provide contextual understanding. With this in mind, Linknode is creating a tool that enables users to visualise proposals in three-dimensional mixed-reality environment, providing real-time integration with BIM and 3D data on-screen. The benefit of seeing a development in context and in scale is to decrease fear, misunderstanding and doubt while increasing engagement with the planning process and building more ownership with stronger communities.

In the Future of Planning we will adapt our capacity to deliver mobile experiences to consumer applications for the first time.

New SNH Visualisation Guidance Published (Lighting)

We were reminded today that the latest version of the SNH “Visual Representation of Wind Farms” came out of draft and was published last month (February 2017).

Version 2.2 of the guidance is an iterative update following the major release update (v2.0) in summer 2014 and the v2.1 revisions in December the same year.

A summary document of changes has been published as a separate download and provides practitioners and interested parties a rapid insight into the changes without the need to compare paragraph by paragraph.  The major change, impacting visual assessment and output for new developments is in paragraphs 174-177:

Turbine Lighting

For turbines in excess of 150m, the need to consult on new lighting visuals is now required.  Although future technical mitigation may help here, there is currently the recommendation to capture images at dusk and create a photomontage based on existing lighting (static streets, moving vehicles, other aviation lighting).
The visualisation should use photographs taken in low light conditions, preferably when other artificial lighting (such as street lights and lights on buildings) are on, to show how the wind farm lighting will look compared to the existing baseline at night.

NOT the Way to Visualise Wind Turbine Lighting!

Specifically the guidance makes reference to innovation in that SNH “encourage applicants to explore new techniques to do this, and emphasise the importance of early dialogue

We are looking for someone who will be creating night light visualisations to ensure that our upcoming night light features being built into VentusAR will work. If you have a project at the right stage, get in touch!

Animation

As we have experienced with the difference between animated wind turbines when compared against static imagery, there is a big difference between views of lighting where all the turbines are at a “maximum visibility” (worst case scenario) visibility and a more normalised situation with different wind directions and rotation occluding lights at certain times.  The more realistic effect can create a fairy lights twinkling effect, but is more representative.

VentusAR included in 3D Technology in Planning Report

This week the research report “USE OF DIGITAL AND 3D VISUALISATION TECHNOLOGY IN PLANNING FOR NEW DEVELOPMENT” was published by the Scottish Government.Planning_Report

This independent report examines the role and potential of digital imagery and 3D visualisation in the planning process in Scotland. Produced by the James Hutton Institute in Aberdeen, it was commissioned to inform the review of the planning system.

The report makes reference to the work of Linknode in the use, acceptance and value of 3D visualisation in planning, especially for real-time, in-situ visualisations for better contextual understanding of change and development (George – our technical director – was especially pleased as the report includes a photo of him using VentusAR at Clyde Wind Farm).

GBIt details the importance of digital equivalence in planning and how future advances in 3D visualisations should be embraced by local authorities and developers at earlier stages in the planning process to improve engagement and understanding.

Linknode entirely support this direction and look forward to on-going participation in the development of 3D visualisation in planning & development in Scotland and beyond. To be involved further, review the “Places, People and Planning” consultation of the future of the Scottish Planning System with opportunities to respond.

Report History and Scottish Planning Review

As previously blogged, this is part of the Scottish Planning Review that started with a call for evidence in September 2015.  The response to this was published in July 2016 (our comments here), leading to the commissioning of a report in October 2016 into the use of 3D visualisation technology in planning for new development.  This was funded by the Planning & Architecture Division of the Scottish Government.

Case Study: VentusAR

Out of the 44 bits of technology mentioned in the the report, our VentusAR and UrbanPlanAR solutions for delivering visualisations is noted as the only mobile augmented reality tool (see Annex A for full list).  Of course, we are also based in Glasgow making our contributions innovative, relevant and local!

The report provides a case study on VentusAR for providing in-field Augmented Reality for Agri-Renewables. The key benefits highlighted in this case study are:

  • The use of real world imagery (still or animated) provides high levels of realism for use at early stages of a project.
  • A low cost and level of risk associated with the investment in the visual representations.
  • The incorporation of real-world video enables the representation of movement in the landscape (e.g. swaying trees, vehicles) […] and thus important in coherent representation of a scene of proposed change.
  • Coherence supports the impression of credibility of visualisations.
