Abstract
Abstract. The intent of this paper is to demonstrate the cultural value that Virtual Heritage experiences can generate. As a proof of concept, game resolution assets were optimized from high polygon image based models (IBMs) and rendered in real-time, within a Head Mounted Display (HMD). The case study of lot 3317 was chosen to facilitate heuristic explorations pertinent to the history of the St. Lawrence Seaway, Canada. This case study explores methods in creating and validating heritage values, while valourizing assets as a cultural resources for use in the future. While at the same time, challenging the current spatial dynamics by conceptually reducing the distance between the viewer and the flooded landscape. In addition to demonstrating the cultural values generated through the veneration of lot 3317, the paper aims to provide a model for optimizing and post processing meshes produced through Under-Water Image-Base Modelling.
Highlights
Most 6Dof Virtual Heritage (VH) systems are rendered in real time, and as a result mesh surfaces generated from typical structure from motion (SFM) pipelines are not ideal assets for these types of experiences. 3 major aspects that limit image based models (IBMs) mesh surfaces from being game resolution assets are their polygon face distribution, overall polygon count and in some cases their unoptimized UV maps
The workflow proposed in this study for optimizing underwater IBMs has been derived from standard protocols and procedures commonly used by the Computer Graphics (CG) industry in producing game resolution assets
Pre-production involves the planning and required research leading to the capturing of data, production refers to typical image based modelling techniques, and post production refers to the optimization of these models
Summary
Many flooded sites are extremely close to popular tourist destinations. The unfortunate reality is that even with many destinations relatively close, these sites go unnoticed. This is due to the fact that each site is not publicly recognized and they are only accessible by boat, making them extremely difficult to find. Canadian economic and national development derived primarily from natural resources in the major metropolitan centres along the St. Lawrence River and Upper Canada. The shoreline of the St. Lawrence was spotted with early loyalist settlements, farms, hamlets and villages. Lake St. Lawrence was the resulting creation, a 100 square mile headpond approximately 60km long
