期末大整合ㄚㄚㄚ
1.首先是打光兒，一樣是用茶壺當主角
#include <GL/glut.h>
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 };
void display()
{
glClearColor(1,0,0,0);
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glColor3f(1,1,0);
glutSolidTeapot(0.3);
glutSwapBuffers();
}
int main(int argc,char**argv)
{
glutInit(&argc,argv);
glutInitWindowSize(500,500); //視窗大小
glutInitWindowPosition(700,200); //視窗位置
glutInitDisplayMode(GLUT_DOUBLE |GLUT_DEPTH);
glutCreateWindow("Week17 review");
glEnable(GL_DEPTH_TEST);
glDepthFunc(GL_LESS);
glEnable(GL_LIGHT0);
glEnable(GL_NORMALIZE);
glEnable(GL_COLOR_MATERIAL);
glEnable(GL_LIGHTING);
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);
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);
glutDisplayFunc(display);
glutMainLoop();
}
2.T-R-T跟移動關節 還有存讀檔
#include <GL/glut.h>
#include <stdio.h>
FILE * fout = NULL;
FILE * fin = NULL;
float angle[20]={};
int angleID=0;
void keyboard(unsigned char key,int x,int y){
if(key=='0') angleID=0;
if(key=='1') angleID=1;
if(key=='2') angleID=2;
if(key=='3') angleID=3;
if(key=='4') angleID=4;
if(key=='5') angleID=5;
if(key=='6') angleID=6;
if(key=='s'){///存檔
if( fout==NULL ) fout = fopen("angle.txt", "w+");
for(int i=0; i<20; i++) fprintf(fout, "%.2f ", angle[i]);
fprintf(fout, "\n");
printf("save angle.txt\n");
}else if(key=='r'){///讀檔
if( fin==NULL ) fin = fopen("angle.txt", "r");
for(int i=0; i<20; i++) fscanf(fin, "%f", &angle[i]);
glutPostRedisplay();///重畫畫面
printf("read angle.txt\n");
}
}
float oldX=0;
void mouse(int button, int state, int x, int y){
oldX = x;
}
void motion( int x, int y ){
angle[angleID] += x-oldX;
oldX = x;
glutPostRedisplay();///重畫畫面
}
void display(){
glClearColor( 1,0,0,0);///用來Clear的Color 用紅色
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glPushMatrix();
glColor3f( 1,1,0 );
glutSolidTeapot( 0.3 );///身體先註解掉身體,只看手臂
glPushMatrix();
glTranslatef(-.3, 0, 0);///(3)再把轉動中的手臂,掛到肩上
glRotatef(angle[0], 0,0,1);///(2)再轉動它
glTranslatef(-.3, .1, 0);///(1)移動旋轉中心,放正中心
glutSolidTeapot(0.3);///左手臂
glPushMatrix();
glTranslatef(-.3, 0, 0);///(3)再把轉動中的手臂,掛到肩上
glRotatef(angle[1], 0,0,1);///(2)再轉動它
glTranslatef(-.3, 0, 0);///(1)移動旋轉中心,放正中心
glutSolidTeapot(0.3);///左手臂
glPopMatrix();
glPopMatrix();

glPushMatrix();

glTranslatef(+.3, 0, 0);///(1)移動旋轉中心,放正中心
glutSolidTeapot(0.3);///右手肘
glPopMatrix();
glPopMatrix();
glPopMatrix();
glutSwapBuffers();
}
