java - OpenGL + Slick Loaded Textures Are Rotating -


i using opengl create 3d game engine in java. , using slick library implement textures. using method create rectangle/square prisms (6 squares/rectangles). in same method, implement textures.

the problem 5 sides of prism render 90 degrees rotated textures. doesn't matter when maing floor since using on brick wall texture isn't looking right.

since wall care 4 sides of it.

the wall texture being rendered 90 degrees rotated on 3 sides of prism. , rendered without rotation on 1 side.

i couldn't work problem out. need change how texture implemented?

here method creating prism.

public static void quadprizm(float x, float y, float z, float sx, float sy, float sz, texture tex){     glpushmatrix();     {         gltranslatef(x, y, z);          tex.bind();         glbegin(gl_quads);         {             //rotated (wrong)             gltexcoord2f(0, 0); glvertex3f(-sx/2, -sy/2, sz/2);             gltexcoord2f(0, 4); glvertex3f(sx/2, -sy/2, sz/2);             gltexcoord2f(4, 4); glvertex3f(sx/2, sy/2, sz/2);             gltexcoord2f(4, 0); glvertex3f(-sx/2, sy/2, sz/2);              //the correct side             gltexcoord2f(0, 0); glvertex3f(-sx/2, -sy/2, -sz/2);             gltexcoord2f(0, 4); glvertex3f(-sx/2, sy/2, -sz/2);             gltexcoord2f(4, 4); glvertex3f(sx/2, sy/2, -sz/2);             gltexcoord2f(4, 0); glvertex3f(sx/2, -sy/2, -sz/2);              //rotated (wrong)             gltexcoord2f(0, 0); glvertex3f(-sx/2, -sy/2, -sz/2);             gltexcoord2f(0, 4); glvertex3f(-sx/2, -sy/2, sz/2);             gltexcoord2f(4, 4); glvertex3f(-sx/2, sy/2, sz/2);             gltexcoord2f(4, 0); glvertex3f(-sx/2, sy/2, -sz/2);              //rotated (wrong)             gltexcoord2f(0, 0); glvertex3f(sx/2, -sy/2, -sz/2);             gltexcoord2f(0, 4); glvertex3f(sx/2, -sy/2, sz/2);             gltexcoord2f(4, 4); glvertex3f(sx/2, sy/2, sz/2);             gltexcoord2f(4, 0); glvertex3f(sx/2, sy/2, -sz/2);              //bottom side             gltexcoord2f(0, 0); glvertex3f(-sx/2, -sy/2, -sz/2);             gltexcoord2f(0, 4); glvertex3f(sx/2, -sy/2, -sz/2);             gltexcoord2f(4, 4); glvertex3f(sx/2, -sy/2, sz/2);             gltexcoord2f(4, 0); glvertex3f(-sx/2, -sy/2, sz/2);              //top side             gltexcoord2f(0, 0); glvertex3f(-sx/2, sy/2, -sz/2);             gltexcoord2f(0, 4); glvertex3f(sx/2, sy/2, -sz/2);             gltexcoord2f(4, 4); glvertex3f(sx/2, sy/2, sz/2);             gltexcoord2f(4, 0); glvertex3f(-sx/2, sy/2, sz/2);         }         glend();     }     glpopmatrix(); }

with following line, create cube wall texture.

draw.cube(0, 10, 10, 5, 5, 5, wall);

here one of 3 rotated sides: one of 3 wrong sides

here only side correct: the correct side

i have solved problem changing texture coordinates. new code this:

public static void quadprizm(float x, float y, float z, float sx, float sy, float sz, texture tex){ glpushmatrix(); {     gltranslatef(x, y, z);      tex.bind();     glbegin(gl_quads);     {         //rotated (wrong)         gltexcoord2f(4, 0); glvertex3f(-sx/2, -sy/2, sz/2);         gltexcoord2f(0, 0); glvertex3f(sx/2, -sy/2, sz/2);         gltexcoord2f(0, 4); glvertex3f(sx/2, sy/2, sz/2);         gltexcoord2f(4, 4); glvertex3f(-sx/2, sy/2, sz/2);          //the correct side         gltexcoord2f(0, 0); glvertex3f(-sx/2, -sy/2, -sz/2);         gltexcoord2f(0, 4); glvertex3f(-sx/2, sy/2, -sz/2);         gltexcoord2f(4, 4); glvertex3f(sx/2, sy/2, -sz/2);         gltexcoord2f(4, 0); glvertex3f(sx/2, -sy/2, -sz/2);          //rotated (wrong)         gltexcoord2f(4, 0); glvertex3f(-sx/2, -sy/2, -sz/2);         gltexcoord2f(0, 0); glvertex3f(-sx/2, -sy/2, sz/2);         gltexcoord2f(0, 4); glvertex3f(-sx/2, sy/2, sz/2);         gltexcoord2f(4, 4); glvertex3f(-sx/2, sy/2, -sz/2);          //rotated (wrong)         gltexcoord2f(4, 0); glvertex3f(sx/2, -sy/2, -sz/2);         gltexcoord2f(0, 0); glvertex3f(sx/2, -sy/2, sz/2);         gltexcoord2f(0, 4); glvertex3f(sx/2, sy/2, sz/2);         gltexcoord2f(4, 4); glvertex3f(sx/2, sy/2, -sz/2);          //bottom side         gltexcoord2f(0, 0); glvertex3f(-sx/2, -sy/2, -sz/2);         gltexcoord2f(0, 4); glvertex3f(sx/2, -sy/2, -sz/2);         gltexcoord2f(4, 4); glvertex3f(sx/2, -sy/2, sz/2);         gltexcoord2f(4, 0); glvertex3f(-sx/2, -sy/2, sz/2);          //top side         gltexcoord2f(0, 0); glvertex3f(-sx/2, sy/2, -sz/2);         gltexcoord2f(0, 4); glvertex3f(sx/2, sy/2, -sz/2);         gltexcoord2f(4, 4); glvertex3f(sx/2, sy/2, sz/2);         gltexcoord2f(4, 0); glvertex3f(-sx/2, sy/2, sz/2);         }         glend();     }     glpopmatrix(); }

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
