Field Detail

frameNumber

protected long frameNumber

Identifies the frame used to calculate this entry's values.

referenceDistance

protected Double referenceDistance

A quick-to-compute metric to determine eye distance changes that invalidate this entry's geometry.

referencePoint

protected Vec4 referencePoint

This entry's reference point.

vboCacheKey

protected Object vboCacheKey

The GPU-resource cache key to use for this entry's VBOs, if VBOs are used.

Constructor Detail

AbstractShapeData

protected AbstractShapeData(DrawContext dc,
                            long minExpiryTime,
                            long maxExpiryTime)

Constructs a data cache entry and initializes its globe-dependent state key for the globe in the specified draw context and capture the current vertical exaggeration. The entry becomes invalid when these values change or when the entry's expiration timer expires.

Parameters:

dc - the current draw context.

minExpiryTime - the minimum number of milliseconds to use this shape before regenerating its geometry.

maxExpiryTime - the maximum number of milliseconds to use this shape before regenerating its geometry.
