OpenGL作為一種圖形與硬件的接口，與其他圖形程序開發(fā)工具相比較，它提供了眾多圖形函數(shù)，直觀的編程環(huán)境簡化了三維圖形的繪制過程，使用OpenGL搭建一個(gè)三維場景，能夠通過輸入設(shè)備與場景內(nèi)物體交互。

豪華單間

配置環(huán)境：vs22+freeglut庫

1.繪制墻體使其成為封閉空間，在封閉空間內(nèi)完成場景的布置

//空間基本架構(gòu)
void drawWall()
{
    glColor3f(0.47, 0.54, 0.60);//rgb顏色可調(diào)
    GLfloat matWall[] = { 0.37, 0.83, 0.98};
	GLfloat matBlack[] = { 0, 0, 0, 1 };
	GLfloat matWhite[] = { 1, 1, 1, 1 };
	GLfloat matShininess[] = { 40 };
	glMaterialfv(GL_FRONT, GL_AMBIENT, matWall);
	glMaterialfv(GL_FRONT, GL_DIFFUSE, matWall);
	glMaterialfv(GL_FRONT, GL_SPECULAR, matWhite);
	glMaterialfv(GL_FRONT, GL_SHININESS, matShininess);
	glMaterialfv(GL_FRONT, GL_EMISSION, matBlack);
    // 左邊
    drawQuads(-10, 10, -20,
        -10, 10, 0,
        -10, -10, 0,
        -10, -10, -20);
    // 右邊
    drawQuads(10, -10, -20,
        10, -10, 0,
        10, 10, 0,
        10, 10, -20);
    // back
    drawQuads(10, 10, -20,
        -10, 10, -20,
        -10, -10, -20,
        10, -10, -20);
    // 天花板
    drawQuads(10, 10, -20,
        10, 10, 0,
        -10, 10, 0,
        -10, 10, -20);
    // 地板
    glColor3f(0.75, 0.75, 0.75);
    drawQuads(-10, -10, -20,
        -10, -10, 0,
        10, -10, 0,
        10, -10, -20);
}

glMaterialfv ()函數(shù)指定照明模型的材料參數(shù)。

2.繪制一張床將其放在角落（左）

void drawBed()
{
    glColor3f(1, 0.8, 0.5);
    glMaterialfv(GL_FRONT, GL_AMBIENT, matBrown);
    glMaterialfv(GL_FRONT, GL_DIFFUSE, matBrown);
    glMaterialfv(GL_FRONT, GL_SPECULAR, matWhite);
    glMaterialfv(GL_FRONT, GL_SHININESS, matShininess);
    glMaterialfv(GL_FRONT, GL_EMISSION, matBlack);
    // 床頭
    glPushMatrix();
    glTranslatef(-9.5, -6, -16);
    glScalef(1, 8, 8);
    glutSolidCube(1);
    glPopMatrix();
    // 床尾
    glPushMatrix();
    glTranslatef(4.5, -8.5, -16);
    glScalef(1, 3, 8);
    glutSolidCube(1);
    glPopMatrix();
    //床板
    glPushMatrix();
    glTranslatef(-2, -7, -16);
    glScalef(14, 1, 8);
    glutSolidCube(1);
    glPopMatrix();
    //床墊
    glColor3f(0.6, 0.97, 0.6);
    glMaterialfv(GL_FRONT, GL_AMBIENT, matGreen);
    glMaterialfv(GL_FRONT, GL_DIFFUSE, matGreen);
    glMaterialfv(GL_FRONT, GL_SPECULAR, matWhite);
    glMaterialfv(GL_FRONT, GL_SHININESS, matShininess);
    glMaterialfv(GL_FRONT, GL_EMISSION, matBlack);
    glPushMatrix();
    glTranslatef(-2, -6, -16);
    glScalef(14, 1, 8);
    glutSolidCube(1);
    glPopMatrix();
}

效果圖如下：

3.房間的一些基本配置

void drawDesk()
{
    glColor3f(1, 0.8, 0.5);
    glMaterialfv(GL_FRONT, GL_AMBIENT, matBrown);
    glMaterialfv(GL_FRONT, GL_DIFFUSE, matBrown);
    glMaterialfv(GL_FRONT, GL_SPECULAR, matWhite);
    glMaterialfv(GL_FRONT, GL_SHININESS, matShininess);
    glMaterialfv(GL_FRONT, GL_EMISSION, matBlack);
	//書桌
    glPushMatrix();
    glTranslatef(9, -4, -10);
    glScalef(4, 0.5, 20);
    glutSolidCube(1);
    glPopMatrix();

    glPushMatrix();
    glTranslatef(9.75, -7, -10);
    glScalef(0.5, 6, 20);
    glutSolidCube(1);
    glPopMatrix();
	//床頭柜
	glPushMatrix();
    glTranslatef(-8, -8, -10);
    glScalef(4, 4, 4);
    glutSolidCube(1);
    glPopMatrix();
}

這桌子建議改成實(shí)體的bushi
再添置一個(gè)茶壺 bushi

void drawTeapot()
{
    glColor3f(0.80,0.71,0.34);
    glMaterialfv(GL_FRONT, GL_AMBIENT, matBrown);
    glMaterialfv(GL_FRONT, GL_DIFFUSE, matBrown);
    glMaterialfv(GL_FRONT, GL_SPECULAR, matWhite);
    glMaterialfv(GL_FRONT, GL_SHININESS, matShininess);
    glMaterialfv(GL_FRONT, GL_EMISSION, matBlack);

    glPushMatrix();
    glTranslatef(-8, -5.5, -10);
    glRotatef(-100, 0, 1, 0);
    glutSolidTeapot(0.8);
    glPopMatrix();
}
