今天鮪魚蛋餅沒了 week11

 week11

步驟:

1. File-New-Project,GLUT專案(把freeglut準備好)

1.1 source.zip裡:glm.h放專案:桌面week11_model

1.2 glm.c(改glm.cpp),放專案:桌面week11_model

1.3 transformation.c 複製內容,到我們的main.cpp裡

1.4 在CodeBlocks裡,左邊Add File ,glm.cpp加入

程式碼:

#include "glm.h"

GLMmodel*pmodel=NULL;

void drawmodel(void){

    if(!pmodel){

        pmodel=glmReadOBJ("data/porsche.obj");

        if(!pmodel) exit(0);

        glmUnitize(pmodel);

        glmFacetNormals(pmodel);

        glmVertexNormals(pmodel,90.0);

    }

    glmDraw(pmodel,GLM_SMOOTH | GLM_MATERIAL);

}

void display(){

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    drawmodel();

    glutSwapBuffers();

}

int main(int argc,char**argv){

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE |GLUT_DEPTH);

    glutCreateWindow("Week11");

    glutDisplayFunc(display);

    glutMainLoop();

}

程式碼:

#include "glm.h"

        glmFacetNormals(pmodel);

        glmVertexNormals(pmodel,90.0);

    }

    glmDraw(pmodel,GLM_SMOOTH | GLM_MATERIAL);

}

void display(){

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glRotated(180,0,1,0);

        drawmodel(); 

    glPopMatrix();

    glutSwapBuffers();

}
