Imports

Minimalistic grouping strategy useful for orthogonal scenes where the camera faces the negative z axis. Handles enabling and disabling of blending and uses world-z only front to back sorting for transparent decals.

States (* = any, EV = entry value - same as value before flush):

expects exits on
glDepthMask true EV | true
GL_DEPTH_TEST enabled EV
glDepthFunc GL_LESS | GL_LEQUAL EV
GL_BLEND disabled EV | disabled
glBlendFunc * *
GL_TEXTURE_2D * disabled

Method Detail

compareback to summary
public int compare(Decal a, Decal b)

Implements java.util.Comparator.compare.

Doc from java.util.Comparator.compare.

Compares its two arguments for order. Returns a negative integer, zero, or a positive integer as the first argument is less than, equal to, or greater than the second.

The implementor must ensure that signum(compare(x, y)) == -signum(compare(y, x)) for all x and y. (This implies that compare(x, y) must throw an exception if and only if compare(y, x) throws an exception.)

The implementor must also ensure that the relation is transitive: ((compare(x, y)>0) && (compare(y, z)>0)) implies compare(x, z)>0.

Finally, the implementor must ensure that compare(x, y)==0 implies that signum(compare(x, z))==signum(compare(y, z)) for all z.
