Discussions / Miscellaneous Topics / Re: Why am I an idiot?

i know exactly what ur talking about.. i havent graduated yet from university.. i started in computer science and when i was learning C++ i was reading and playing with more that what i was thought .. we learend console applications and i was already playing with opengl, glut and glut based GUI. when i started learning data structures in C++ i was more interested in what java is and how to use it, i was writing my data structures in java when my assignments r in C++ and end up not finishing my c++ project. when i did unix system programming i was more interested in how to daul install linux and windows together and how to hack and compile the kernel.. so the teacher introduce the course and i go off course to learn more stuff not covered in the course.
there is more to my story , the end is that im now senior in computer engineering and minor in computer science.. no degree yet. but im working as a software engineer, the recruiter was amazed with the stuff that i know and i passed all the interviews so i got hired.
few months ago i was going crazy about .net and mono, but when i heard that java is going GPL i went back to java , yet im trying to learn C# now. i have learned from my mistakes, first "keep it simple", then when u solve the problem u can look into how to make a better solution. but first solve the problem before anything else.
ur not an idiot, u just cant thing about one thing at a time, ur mind creates threads of thoughts that pulls u away from the main objective.
the solution is in ur mind buddy.
good luck to you.

ok im trying to understand what u mean.. do u mean that i need to create a sperate class for event handeling and have a methode that determinds where the event came from and take action according to that ? im looking into my design AGAIN. and i can see somthing interesting .. im using board squars as object in board, that means that board squares is stand alone, but board requaires boardsquare as part of it , it is declared as an object withen the class. but if i use inheretince instead of createing object , then the code may look cleaner, and easy transition to see what new features where added to class board. im going to look again into those issues, i got the even handelign and all i need to know to get this working, but im looking into best design that is easy to follow and resue and maintain or modify by others who want to create their own chess board or checkers board or what ever board. i enjoy ur openions  .. thanks..

once again i modyfied my solution .. made better use of inheritence and use JPanel instead of JFrame and then added panels to it.. now my code does update and move, as i used paintAll(graphics g) .. also i think my code looks more simple now, even a real biggener can follow. i also added main methode to Piece.java so that u can test it as a stand alone application, and see if it adds the chess piece . so here it is .. peace 1

ok .. here is my new code, i ca now add all pieces to the chess board and show the board with those pieces, i can remove a piece and move it.. but it only removes and i need to minimize then maximize the window to so that i will show the new piece moved.. hmm., i need to look into that. i used some nice chess pieces found on the internet and .. my board looks nice. but again, i need to fix this drawing thing, then i can start writing mouse handling stuff in another class.. suggestions are very very wellcomed and appriciated. here is my code so far. peace 1

i havent looked or did anything extra on my code, im trying to learn jgl more "java gl using pure java" and also hacking it to understand how it is implemted and im using UDoc to get uml like diagrams from the jgl package , to understand it more. i will come back to my chess program "gui at this point" and maybe redo it using jgl and draw everything in 3D. but again this thread is my attempt at that and all i post here is my learning while im doing things .. please be specific about what bla_bla vs blaBla means?? where in my code ur exactly pointing? again, any suggestions and advices r very wellcome.. i learn from everyone. peace |

im trying to add chess piece to my board, then ill attempt to move the piece around , and after that i can create the whole board with pieces in it .. and that is it .. very simple.. as for rules on what is legal and what is not that is up to the logic code or the engine, in fact i might modify my code later on, to be Board.java that shows how to create simple Board , then ChessBoard extends Board that will show how to add pieces and allow moving them on the board. so that others who want to learn how to create a board for any other reasons can use the code . ok, im trying to figure out how to add chess piece, but this is not working.. here is my code now.. 1

wow, interesting .. from 50 using java2D to about 2000 fps in slick using lwjgl.. nice. but agian , jgl can be used where hardware accelaration is not supported , and if supported i think java2d can do well, hopefully in the future better pipline and better performance can be achived in java2d

about java2D being slower than opengl.. i doubt that, if its accelarated using opengl or d3d it shouldnt.. but again maybe some operations more algorithmitic "bad spelling", so uses cpu to compute before sending output to GPU.. i think if u stick to simple operations like lines, triagle and polygons u wont see much difference, .. just my openion.

did u download jgl from robin's site ?? the one he has up there is jgl2.4 beta 3 i think , and the source code for that doesnt compile under jdk1.6 and i dont know how it compiled under jdk1.1 , he has created objects with wrong name so the compiler cant find definition.. any way i fixed that on the copy i got + there will be some casting problems "warrnings " due to using newer and more strict java 1.5 and 1.6.. if u download the source code ull get folder with examples, look at example-app .. that has the examples using glut and can be compiled and run as application.. oh u might want to look at main methode and change Frame to JFrame and then add a mthode for close operation. mainFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); he uses awt , and no closing operation or event handling is provided . im still learning this api and i want to write the same program in C/C++ and java "using jgl".. peace |

yeah i visited the forum and the site, very interesting .. i sent email to robin and he said that he is going to add some new features and upload it soon, i dont know how soon. but for me i think that rewriting the drawing parts to use java2D will surely make better performance, because java2D uses opengl pipeline or d3d .. and it fits well with swing and awt. and again , supported where java2d api is supported , which i have always seen it supported even if the system was embeded like damn small linux. im starting to learn opengl and glut, im reading the red book and i have wrote little demo in C, then translate it to java using jgl, there is little incompatibility in a sense that i didnt see my wire frame square in java, all i got is the black canvas  . but im playing with it.. after i get good handle on this then convert to C++ "piece of cake" then C# using tao api.. and as i learn more then i can propebly with the help of others  change the jgl api to use java2D for drawing. ill post code of my java and C/C++ code using and learning opengl if any one wants to see . peace |

im not sure about performance hit reagarding an api on top of each other.. but im sure u guys heard that java is going open source and GPL. now the standard api that is provided is suppost to run on all platforms in since that u install the jre and it is avaialable..
here is a senario, i use damn small linux to do unix testing of my application, it runs totally from ram and it is only 50 mb, then i install jre and java3D api, everything goes well, but when i run my java3D application it doesnt because i dont have opengl or mesa installed.. that is becuase for this system to be small there is a lot of things omitted, it even uses small x server xvisa or somthing like that. but java runs fine because it can use software emulation when hardware accelaration is not there. so by having JGL in here i can still do opengl on linux and windows and any system that has jre for it.
i have tried some of the glut examples in JGL and the performance was ok with softwar emulation. and i think if we can rewrite the drawing parts with java2D then we can gain more performance without having the fliker problem when an api uses gl and the component uses directX or direct 3D .. the case of jogl and java3D with swing.
any way .. if u download the source code it will not compile , it has errors.. i have them fixed so if u want it i can email it to u, i use netbeans 5.5 and jdk1.6 rc 1.

hi i came across this api, called jgl, u can google it, it is written using pure java, that means build on top of libraries provided with jre by default, nothing extra needed. it has gl calls and glut calls too. i have downloaded the source code which didnt compile at first. fixed it got rid of the warrning that is genarated due to outdated casting problem with jdk1.1.
the api and code is GPL. so we can basically modify it and so on .. any one interested in modifying the library to use java2d instead? this could provide good speed.

hi,
discuss why java3D is not or is good for game progamming in java , in particular first person shooter. compare it with jogl and lwjgl as they r the most famous.
i have tried java3D, not easy to learn at first, but then u come to appreciate the design. im not sure about performance. it integrates well with other java components. on the other hand jogl seems to be little buggy and not backward compatibe with previous versions. i have seen jake2 which is quake 2 ported to java using lwjgl and jogl and joal. never seen an fps written completly using java3D yet..

ok .. i was looking and found this ... hope it can help others.. /* * Example 2: Hello JOGL * * Draws a multi-colored triangle to the GLCanvas. As in the previous * example, the GLCanvas is placed in a JFrame and made visible. This * time OpenGL functions are called in the init, reshape and display * methods to set up the OpenGL environment and draw the triangle. * OpenGL commands can only be executed within the GLEventListener * methods (when called automatically). The OpenGL context is not * current anywhere else, and OpenGL calls will have no effect. * * It is recommended to always retrieve the GL object from the * GLDrawable parameter in the GLEventListener methods as opposed to * storing the object in a instance variable. The reason for this is * that if it is stored in an instance variable, it is too easy to * use it to call OpenGL methods in places other than the GLEventListener * methods. * * Author: David Wolff * * Licensed under the Creative Commons Attribution License 2.5: * http://creativecommons.org/licenses/by/2.5/ */ //package tutorial.b_HelloJOGL; import java.awt.BorderLayout; import javax.media.opengl.GL; import javax.media.opengl.GLAutoDrawable; import javax.media.opengl.GLCanvas; import javax.media.opengl.GLEventListener; import javax.swing.JFrame; public class HelloJOGL implements GLEventListener { /* * Set up the background color, and clear the modelview matrix. */ public void init( GLAutoDrawable d ) { GL gl = d.getGL(); gl.glClearColor( 0,0,0,0 ); gl.glMatrixMode( GL.GL_MODELVIEW ); gl.glLoadIdentity(); } /* * Set up a simple orthographic projection, with a square * window. */ public void reshape( GLAutoDrawable d, int x, int y, int width, int height ) { GL gl = d.getGL(); gl.glMatrixMode( GL.GL_PROJECTION ); gl.glLoadIdentity(); gl.glOrtho( -1.0, 1.0, -1.0, 1.0, -0.1, 0.1 ); gl.glMatrixMode( GL.GL_MODELVIEW ); } /* * Draw a triangle. */ public void display( GLAutoDrawable d ) { GL gl = d.getGL(); gl.glClear(GL.GL_COLOR_BUFFER_BIT); gl.glBegin( GL.GL_TRIANGLES ); gl.glColor3f(1.0f,0.0f,0.0f); gl.glVertex2d( -0.75, -0.75 ); gl.glColor3f(0.0f,0.0f,1.0f); gl.glVertex2d( 0.75, -0.75 ); gl.glColor3f(0.0f,1.0f,0.0f); gl.glVertex2d( 0.0, 0.75 ); gl.glEnd(); } /* * Create a JFrame containing a GLCanvas.
