APPSERV installation Guide

APPSERV software package contains php programming, mysql database, apache server and phpmyadmin.

php programming - programming language
mysql - database
apache - web server 
phpmyadmin - software to view 'live' mysql database structure

Same as XAMPP, WAMP, PHPTRIAD, WEBDEV....

Ask Mr. Google and Download by Yourself...

For all my student...

Carilah seribu sahabat dalam pergaulan,

kerana seribu sahabat belumlah banyak.

Jauhilah seorang musuh, kerana musuh yang

seorang itu sudah lebih daripada banyak.

Mapping Texture (Raw image) into Object

//fstream declaration
//glut header declaration

GLuint texture; //as global variable

//function only works for RAW format image
GLuint loadtex(const char *filename, int w, int h)  //unasigned integer
{
    GLuint tex;
    FILE *file;
    unsigned char *data;
   
    file=fopen(filename,"rb");
    if(file==NULL) return 0;
   
    //preparation
    data=(unsigned char *)malloc(w*h*3);
    fread(data,w*h*3,1,file);
    fclose(file);

    //generate texture name
    glGenTextures(1,&tex);
    glBindTexture(GL_TEXTURE_2D,tex);

    //texture environment
    glTexEnvf(GL_TEXTURE_ENV,GL_TEXTURE_ENV_MODE,GL_MODULATE);

    //set texture environment parameters
    glTexParameterf(GL_TEXTURE_2D,GL_TEXTURE_MIN_FILTER,GL_LINEAR);
    glTexParameterf(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER,GL_LINEAR);
    glTexParameterf(GL_TEXTURE_2D,GL_TEXTURE_WRAP_S,GL_REPEAT);
    glTexParameterf(GL_TEXTURE_2D,GL_TEXTURE_WRAP_T,GL_REPEAT);

    //connect data to GL_TEXTURE_2D
    glTexImage2D(GL_TEXTURE_2D,0,GL_RGB,w,h,0,GL_RGB,GL_UNSIGNED_BYTE,data);
    free(data);

    return tex;
}

void renderscene()

    glLoadIdentity();
    gluLookAt(0,0,-3,0,0,0,0,1,0);

    //enable

Create Text using Function

Just replace the ASCII code character codes with below function =) Simple and more effective!

void placetext(float x, float y, float z, void *font, char *string)
{
    char *c;
    glRasterPos3f(x,y,z);
    for(c=string; *c!='\0'; c++)
    {
        glutBitmapCharacter(font,*c);
    }
}

and replace your codes at display( ) function with;

placetext(0,0,0,GLUT_BITMAP_HELVETICA_18,"Hai Fiza!!");

My first ASCII Text using OpenGL

//OpenGL include goes here

GLfloat year=0;
GLfloat day=0;

void reshape(int w, int h)
{
    glViewport(0,0,w,h);
    glMatrixMode(GL_PROJECTION);
    glLoadIdentity();
    gluPerspective(60,1,0.5,400);
    glMatrixMode(GL_MODELVIEW);   
    glLoadIdentity();
}

void display(void)
{
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    glEnable(GL_DEPTH_TEST);
    glLoadIdentity();

    glRasterPos2f(0,0);
    //glRasterPos3f(0,1,0);
    glutBitmapCharacter(GLUT_BITMAP_9_BY_15,72);   
    glutBitmapCharacter(GLUT_BITMAP_9_BY_15,65);   
    glutBitmapCharacter(GLUT_BITMAP_9_BY_15,70);
    glutBitmapCharacter(GLUT_BITMAP_9_BY_15,73);
    glutBitmapCharacter(GLUT_BITMAP_9_BY_15,90);
    glutBitmapCharacter(GLUT_BITMAP_9_BY_15,65);
    glutBitmapCharacter(GLUT_BITMAP_9_BY_15,72);
   
    gluLookAt(0,0,-2,0,0,0,0,1,0);
    glutSwapBuffers();
}

int main(int argc, char **argv)
{
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_DEPTH | GLUT_DOUBLE | GLUT_RGBA);
    glutInitWindowPosition(100,100);
    glutCreateWindow("Text Example");
   
    glutDisplayFunc(display);
    glutReshapeFunc(reshape);   

    glutMainLoop();
    return(0);
}
