Isometrci tile map

[Grand Poeba]

Hye is have made an isometric map based on a tile both useing java2d and xith3d (jogl render)

and with java2d my tiles look fine but it is so slow and not very efficitent
my xith3d has bad looking tiles but paint s much better

anyone has any idea to make the java 2d version much more effictien and paint/update much faster
or knows how i can make xith3d make same map as my java2d version
