Challenges
POWER COMPLEXITYSIZE
Online Access ChallengesServe a wide variety of needs and usersMaximise the 3D user experienceFocus on accessibility - easy and intuitiveMaximise the availability of the 3D content on as many browser platforms as possible (desktop and mobile)Focus on single release of models - efficient & sustainable productionAvoid users having to install additional software or plug-insSupport the concept of resource exploration (e.g. integrated URLs)
Retopologisation
Normal Maps
Texture creation - panoramic image capture

Irish Film Board• Met with film commissioner of Irish Film Board
• Use 3D content as an enticement to production companies looking to film in Ireland:
- Pre-production planning - Post production VFX
• Could money raised go towards scanning more heritage sites which the film board could market?
