電腦圖學week12

1.安裝3D Exploration

2.另存cpp Open GL檔案

3.CodeBlocks開OpenGL方案，選擇Remove file from project，Add files gundam_3dexp.cpp

4.加入兩行程式碼 #define GL_BGRA_EXT 0x80E1

                                  #define GL_BGR_EXT 0x80E0

5.註解掉兩行程式碼 //(LPLOGPALETTE) lpPalette = (LPLOGPALETTE)HeapAlloc (hHeap, 0,

                                      //sizeof (LOGPALETTE) + (nColors * sizeof (PALETTEENTRY)));

6.移除旋轉與放大縮小 加入 glRotatef(nAngle,0,1,0);

                                                    glScalef(3,3,3);

7.1 HW4教學:保留打光程式碼

#include <GL/glut.h>

void display()

{

    glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glutSolidTeapot( 0.3 );

    glutSwapBuffers();

}

///下面是從 GLUT專案main.cpp剪貼來的

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 };

int main( int argc, char** argv )

{

    glutInit( &argc, argv );

    glutInitDisplayMode(GLUT_DOUBLE |GLUT_DEPTH);

    glutCreateWindow("week12 hw4");

    glutDisplayFunc(display);

    ///下面是從 GLUT專案main.cpp剪貼來的

    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);

    glutMainLoop();

}

7.2 修改執行目錄，把freeglut.dll移到week12_hw4
