228 14. Budgeting Frame Time

In Listing 14.4, the list of drawables (this.entities) is kept separate from the

FIFO of updateables (this.queue). If an entity needs to be updated—for example,

tohave its texture replaced or VBO rewritten—then it needs to be explicitly added to

the FIFO.

Aside: Sort your drawables! Order matters. Semitransparent objects should be at the end

of the list for proper blending. Large occluders should be at the beginning of the list, so

that subsequent entities that are occluded will fail the depth test right away, rather than

going through fragment shading.
