JAVA - LWJGL - Texture rotation -

-

can tell me real quick how rotate texture var degrees in lwjgl when have coordinates , origin? well, looks right now: x/y center of texture.

public void render(float x, float y) {     glpushmatrix();     texture.bind();      gltranslatef(x - xorigin, y - yorigin, 0);      //this false. ignore     //glrotatef(45f, 0f, 0f, 1f);      glbegin(gl_quads);     {         gltexcoord2f(0, 0);         glvertex2f(0, 0);          gltexcoord2f(0, width);         glvertex2f(0, height);          gltexcoord2f(texture.getwidth(), texture.getheight());         glvertex2f(width, height);          gltexcoord2f(texture.getwidth(), 0);         glvertex2f(width, 0);     }     glend();      glpopmatrix(); }

thanks

if want rotate textures need change uv coordinates, thereby rearranging gltexcoord2f(u, v) though rearranging them rotate them 90deg/1.57rad per rearrange, though if want smaller rotations of texture, can calculate u, v coordinates using trigonometry cos , sin functions.

plot - Remove Objects from Legend When You Have Also Used Fit, Matlab -

i've plotted data points , fitted exponential curve between them using 'fit' in matlab. problem fit-function got fitted line wanted plot, markers on top of regular markers. solved problem plotting wanted markers on top of unwanted couldn't seen. problem. when want show legends dots in there. how can remove markers legend without removing fitted line since both of them hidden inside fit-function? can stop 'fit' plotting unwanted markers? so, want remove blue dot called 'hoff' in picture below. you can leave out legend-entries manually leaving out handles of lines, dont want in legend. try this: %if plot something, want showing in legend, save handle: h_line = plot(x,y) %you dont want show line? dont anything, plot it: plot(mymarker) %then set legend-> can add text legend-entries %a cell-array containing strings want show up: legend([h_line another_line],{'text1' 'text2'}) with example (see comments) came solution: ...

java - Why does my date parsing return a weird date? -

-
here code using: string string = "08/07/2013".replace('/', '-'); date date = new simpledateformat("yyyy-mm-dd").parse(string); why date return: "wen jan 3 00:00:00 est 14"? not @ date format told use. edit: need format because database using requires format. the format use parse date string, not match it. using yyyy 08 . use following format: new simpledateformat("dd-mm-yyyy") and why @ replacing / - ? can build pattern original string only: string string = "08/07/2013" date date = new simpledateformat("dd/mm/yyyy").parse(string); and if want date string in yyyy-mm-dd format, can format date using dateformat#format(date) method: string formatteddate = new simpledateformat("yyyy-mm-dd").format(date); see also: change date format in java string simpledateformat java doc
