 製作自己的Transformation

首先去moodle下載data, source, windows檔案並解壓縮

然後開啟GLUT專案

將main.cpp裡面的程式碼刪掉將transformation.c裡的程式碼複製貼上

然後將source裡的glm.c, glm.h, transformation.c丟入資料夾中

並將glm.c的檔名改成.cpp

然後將glm.cpp加入專案裡(左邊Project按右鍵Add Files選擇glm.cpp)

執行看看如果會閃退的話就是程式碼完成了!

最後將data裡的檔案丟到freeglut/bin裡面

執行看看就完成了

#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();

}
