For the last few weeks Dave has been taking us through terminology, constraints and workflows as related to accuracy of heritage in 3D capturing, processing and rendering. In this brief summary (complete with a demonstrative image) he drives home the importance of being clear on the terminology we use and the extents of our own discipline as applied to this. Once you have had a read I encourage you to check out the UE4 “making of” videos which go over capturing, processing and presenting 3D imagery. Both myself and Dave have oggled these videos with envy numerous times, and it should be stressed that this is a gold standard or benchmark of production rather than a mode for standard operating procedure. Even so, such benchmarks are important for informing our understandings and practices – so check them out HERE and HERE! At the end of the short post there is a poll – this time some feedback as to what you think the key workflow area is that affects the ability to produce accurate 3D models for heritage.
So I hope over this series that I’ve taken you through some of the pitfalls that artists have to deal/wrestle with in trying to achieve this fabled 100% accuracy in their models/textures. There are many more, some of which I’ve not foreseen due to lack of experience in some areas. Yes with the right team/vision it is possible to achieve accuracy in the high 90% range but 100%?
If the object you’re capturing isn’t 100% accurate (physically changes over time) then how can the recreation of that object be 100% accurate? Surely it’s a flawed notion. Yes, I may be being pedantic…to be really awkward I could argue that on an atomic level it will never be accurate but as a client, the world of heritage needs to understand the weight of terminology and its impact on the vendor……basically, be realistic!
I think it is important to address this issue as it not only puts unreachable expectations/pressure on artists, also presents a conundrum for the world of heritage. This in effect will have repercussions on how digital recreations are presented to the public and will (I hope) prompt a change in terminology and understanding within the heritage community.
So for the last part of this series, in the next post, I’m going to explore how heritage can go about this with some proposals… For now it is time to have your say! What do you think is the key factor influencing the ability to capture, record and produce accurate 3D heritage material? Answer the poll below and leave a comment!
