Class BakedTextBlob

java.lang.Object

icyllis.arc3d.granite.BakedTextBlob

public final class BakedTextBlob
extends Object

A BakedTextBlob contains a fully processed TextBlob, suitable for nearly immediate drawing on the GPU. These are initially created with valid positions and colors, but with invalid texture coordinates.

A BakedTextBlob contains a number of SubRuns that are created in the blob's arena. Each SubRun tracks its own glyph and position data.

In these classes, I'm trying to follow the convention about matrices and origins.

• drawMatrix and drawOrigin - describes transformations for the current draw command.
• positionMatrix - is equal to drawMatrix * [drawOrigin-as-translation-matrix]
• initial Matrix - describes the combined initial matrix and origin the TextBlob was created with.
