Motivation
See Virtual Planet Builder for the main article about this subject. |
Virtual Planet Builder (VPB) is OSG's terrain-database-building tool.
It loads GIS elevation data for a
region, combines it with imagery and produces a spatially-balanced
quadtree tiled database that can be navigated simply by loading the
top-level file. All of the LOD Ranges are pre-configured and the
DatabasePager automatically loads and unloads different segments of
terrain without any supporting userspace code required. VPB can build
terrain models ranging from a small area to the entire planet. These
databases can be fluidly navigated at 60fps from outer space down to
ground level with no interruptions. The terrain models are built of
regular grid arrays with optional edge-skirts to conceal any cracks
caused by adjacent LOD differences. — OpenScenGraph's Virtual Planet Builder/OSGDEM. Published by AlphaPixel, LLC.

Objective
Produce high-quality scenery using the best-known practices.
TerraGear becomes obsolete in favor of VPB.
OpenGL 3.3 Core Profile: WS3.0 will require us to eliminate the usage of the fixed-function pipeline.
Shader-based Rendering: All of the terrain renderings will be done via GLSL shaders.
OSG Core: OpenSceneGraph will require targeting of the OpenGL Core Profile.
WS3.0 will continue to cooperate with osm2city.
Easy upgrade: Airport layouts will be generated in real-time. Apt.dat will continue to be the primary source for airport layouts. Airports will be draped over the terrain. This eliminates the need to cut airport layouts into the underlying terrain.
