Lm's圖學筆記 Week12

 鋼彈

1. 開OPENGL檔案
2. 3D Explorer安裝
3. 解壓縮Gundam檔案(3D Exploration), 開 OBJ檔 SaveAs .cpp檔(SampleAPP)
4. 專案main.c 換成gundam_3dexp.cpp (Remove, Add)
5. Build & Run 有錯誤 新增兩行

#define GL_BGRA_EXT 0x80E1

#define GL_BGR_EXT 0x80E0

 

把旋轉.縮放 / /  換成 glRotatef ( nAngle, 0, 1, 0);

           glScalef ( 3, 3, 3);

 

把鋼彈 Inport 到 MAYA 裡面，選Face模式，選取左手後按File-Export Selection 改成OBJ檔export

開新的GLUT檔案貼入程式

#include <GL/glut.h>

void display()

{

    glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glutSolidTeapot( 0.3 );

    glutSwapBuffers();

}

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_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();

}
