熱血學圖學round11

解壓縮 freeglut-MinGW-3.0.0-1.mp.zip

➡把解壓縮完的檔案移到桌面

➡把124KB的檔案改名成 libglut32.a

檔名:week11-0_sample

要偷他的打光程式


檔名:week11-1_TRT_again

1.把上週的week10_TRT_glutSolidCube_myBody_myArm的程式貼上

2.搭出T-R-T的程設

#include <GL/glut.h>

void myBody(){

    glColor3f(1,0,0);///紅色身體

    glutWireCube(0.6);

}

void myArm(){

    glScalef(1.5,0.5,0.5);

    glutWireCube(0.3);

}

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        ///glTranslatef(-0.6,+0.3,0);

        myBody();

    glPopMatrix();

    glPushMatrix();

        glTranslatef(+0.3,+0.3,0);

        glRotatef(angle++,0,0,1);

        glTranslatef(0.45/2,0,0);

        myArm();

    glPopMatrix();

    glutSwapBuffers();

}

int main(int argc, char *argv[])

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week09-2 glutSolid¨t¦C");

    glutIdleFunc(display);

    glutDisplayFunc(display);

    glutMainLoop();

}

1.安裝openCV2.1,記得Add Path
2.重開CodeBlocks ⇉ Setting ⇉ Compiler

=>利用MAYA把鋼彈的手繪出程OBJ檔
=>用只留下(面)把除了手臂的地方刪掉
=>ExportAll(選擇OBJ)




檔案:week11-3_obj_gundam_hand1_hand2
=>要複製專案week11-2_obj_gundam__opencv_texture_lighting
=>整個目錄 複製成week11-3_obj_gundam_hand1_hand2
=>再把裡面的.cdp改成week11-3_obj_gundam_hand1_hand2
=>CodeBlocks選File-Open,到week11-3_obj_gundam_hand1_hand2目錄裡
    選week11-3_obj_gundam_hand1_hand2.cdp
