| Description | Real-time 3D visualization engines have evolved in both their capacity to render visual fidelity and in their openness to scripting capabilities (photorealism, programmable shaders and object properties, dynamic visualizations). This contribution is to look at the potential and limitations of such implementations with an experimental/educational scope in mind: rendering multiple 3D (cartographic) visualizations of maps/scenes in a controlled experiment-purposed application, with an emphasis on their transition from one visualization to another. While 3D dynamic visualizations offer an increase in choices and customization in display and function (as opposed to traditional/2D media), this does come at a price of rising implementation costs. Both dynamicity and threedimensionality of presented data require algorithms to process this (be it terrains, visibility models, collision models, graphics shaders, or other components). Because such algorithms require initialization time and run-time resources, their optimization is crucial. There are constraints and costs to where/how they can be used, too. Good practices of dynamic experimental scene implementation are discussed; in scene-to-scene transitions, multiple approaches are weighted against each other (multi-scene, in-scene with object transition, in-scene with user viewport transition). Techniques of static data retention and in-scene object manipulation are discussed. The conclusions are grounded in previous and current implementations of such tasks (an educational topographic map application, or ongoing research on cross-cultural differences in foreground-background visual perception) |
