#include <stdio.h>
#include "glm.h"

-------匯入-----------

float angle=0,dx=0;
float angle2=0,dx2=0;
char name[40];
GLMmodel* up[4];

----------設定值------------

void timer(int t)
{
    glutTimerFunc(1,timer,t+1);
    glutPostRedisplay();
}

-----------計數器-------------

const GLfloat light_ambient[]  = { 0.0f, 0.0f, 0.0f, 1.0f };
const GLfloat light_diffuse[]  = { 1.0f, 1.0f, 1.0f, 1.0f };
const GLfloat light_specular[] = { 1.0f, 1.0f, 1.0f, 1.0f };
const GLfloat light_position[] = { 2.0f, 5.0f, -5.0f, 0.0f };

const GLfloat mat_ambient[]    = { 0.7f, 0.7f, 0.7f, 1.0f };
const GLfloat mat_diffuse[]    = { 0.8f, 0.8f, 0.8f, 1.0f };
const GLfloat mat_specular[]   = { 1.0f, 1.0f, 1.0f, 1.0f };
const GLfloat high_shininess[] = { 100.0f };

---------光源宣告---------

void load()
{
    if (!up[0])
    {
        up[0] = glmReadOBJ("data/upv2.obj");
        if (!up[0]) printf("no find");
        glmUnitize(up[0]);
        glmFacetNormals(up[0]);
        glmVertexNormals(up[0],0);
    }
    if (!up[1])
    {
        up[1] = glmReadOBJ("data/down.obj");
        if (!up[1]) printf("no find");
        glmUnitize(up[1]);
        glmFacetNormals(up[1]);
        glmVertexNormals(up[1],0);
    }
}

---------讀入bin中data中的upv2與down-----------

void display()
{
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    load();

    glPushMatrix();
    glRotated(-25,0.2,1,0.2);
    glScaled(0.25,0.25,0.25);
    //glTranslated(-0.5,2,0);
    glRotated(angle2,0,0,1);
    glTranslated(0.68,0,0);
    glmDraw(up[0], GLM_SMOOTH | GLM_MATERIAL);
    glTranslated(0.7,0,0);
    glRotated(-angle,0,0,1);
    glTranslated(0.6,0,0);
    glmDraw(up[0], GLM_SMOOTH | GLM_MATERIAL);
    glPopMatrix();
    if(angle>60) dx=-1;
    if(angle<=0) dx=+1;
    angle+=dx;
    angle2+=1;
    glutSwapBuffers();
}

-----------顯示旋轉-----------

int main(int argc, char *argv[])
{
    glutInit(&argc, argv);
    glutInitWindowSize(600,600);
    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
    glutCreateWindow("Steam");
    glutDisplayFunc(display);
    glutTimerFunc(1,timer,0);
    glClearColor(0,1,1,1);

-----------設定base開啟3D--------

    glEnable(GL_DEPTH_TEST);
    glDepthFunc(GL_LESS);

-----------光源測試------------

    glEnable(GL_LIGHT0);
    glEnable(GL_NORMALIZE);
    glEnable(GL_COLOR_MATERIAL);
    glEnable(GL_LIGHTING);

------------設定光light的設定值---------------

    glLightfv(GL_LIGHT0, GL_AMBIENT,  light_ambient);
    glLightfv(GL_LIGHT0, GL_DIFFUSE,  light_diffuse);
    glLightfv(GL_LIGHT0, GL_SPECULAR, light_specular);
    glLightfv(GL_LIGHT0, GL_POSITION, light_position);

------------物體材質-------------

    glMaterialfv(GL_FRONT, GL_AMBIENT,   mat_ambient);
    glMaterialfv(GL_FRONT, GL_DIFFUSE,   mat_diffuse);
    glMaterialfv(GL_FRONT, GL_SPECULAR,  mat_specular);
    glMaterialfv(GL_FRONT, GL_SHININESS, high_shininess);

    glutMainLoop();

-----------迴圈使其持續顯示----------
