Class GlyphVector

java.lang.Object

icyllis.arc3d.granite.DrawAtlas.PlotBulkUseUpdater

icyllis.arc3d.granite.GlyphVector

public class GlyphVector
extends DrawAtlas.PlotBulkUseUpdater

GlyphVector provides a way to delay the lookup of GPU Glyphs until the code is running on the GPU in single threaded mode. The GlyphVector is created in a multi-threaded environment, but the GlyphStrike is only single threaded (and must be single threaded because of the atlas).

prepareGlyphs

public int prepareGlyphs(int start,
 int end,
 int maskFormat,
 RecordingContext context)

Update atlas for glyphs in the given range if needed, returns the number of glyphs that are updated (may less than end-start if atlas is full). If an error occurred, returns the bitwise NOT (a negative value).
