Notes from visualisation workshop

Notes from yesterday’s Digital Humanities visualisation colloquium at Reading on 31 March.

Reuse of models in different form: tensions between drama and academic use. Life of Rome as MMORPG.

VR seems big: Oculus Rift and Google Cardboard.

What’s the sustainability? As the tools become more available and publication modes. How does the digital output fit into the REF and the tension with the commercial impact.

Donal Campbell: Role of context in reconstruction. Museums and collections are different contexts, May use props to change this. Question of not being able to find the “educated guesses”. Audience interaction with the model.

Reconstruction builds on each other. Used photogrammetry with Autodesk and photographs to reconstruct the physical context. Priority was capturing the metadata used to build it. Data, or lack of, affect reconstructions. Involving the community.

Zena Hamash: “is magic enough?”: Use focus groups to get feedback. New technologies, new variables. Issues in 3d printing: dust and fragility of the item. Reconstruction through 3d and poems. Use groups for quantitive and qualitative purposes. 3d for outreach. Losing context in translation. Scanning like being able to manipulate fragile objects.

Patrick Gibbs: the dwell time is fairly short so can find a way through pathways. Mixing motion capture with gaming engine; photogrammetry with 3d. Available timescales, funding and data. Techniques: 3d laser scanning, EDM survey, photogrammetry, documentary evidence. Reflexive nature of visualisation feed back to the evidence and also raises other questions. Game engine for interactive experience. Question of evidence and how do users understand the subjective nature, and how many care: education and entertainment.

Caradoc Peters: talking about interpretation of items once they’ve become mythologised and put into a landscape. Discussing Tristran Stone and Mermaid of Zennor. Mixture of techniques used: photogrammetry, Fuse3d. Take photo from one position but change flash to get view of an item (RTI / PTM). Ambient Occlusion. Need text, the artefact and context. (see: Developing a low cost 3D imaging solution for inscribed stone surface analysis)

Ildiko Solto: Under theatre. TextDNA to sequence words. Craig’s Screens on Stage. Using 3d to reconstruct the physical space. (how does this affect sound?) Sees it as alternative discourse.

Aylish Wood: how does software shape visualisation. Animation as way of manipulating the data into a visual format.  Using multiple data sources to handle uncertainty. Engagement  is the other form: less interested in hard core realism from data but also requires the context. Colour and emotional engagement.
visual grammar: films.
Interpretative work, not objective.

Paul Johnson: Testing ideas and parameters in a sandbox. Don’t worry about the final rendering. Reformatting when data changes and link to para- or metadata which is web-hosted or linked to a blog.

Using colours to show the level of confidence in a model. Could do this with sounds? Also linking for mining.

Labgraf3d: presentation of technologies for virtual tours.

Felix & Anders: Take measurements from sources using SketchApp. No gaps, and geometry-driven modelling. Real-scale detail. Use the pattern language, start with sketches, and then go into modelling. Goes across technical and domain knowledge.

Tayfon: outreach and to verify the data.

Cyprus: 3 d stereoscopy for perception as well as modelling. Reconstructing collections scattered across museums reconstructed virtually. Used images to reconstruct a model of an object not in own control. Leads to story telling in the environment.

Baker: Use of non-technical skills to do the ground work in Rome.  Models convey the scene pulling the data together.
