File-New-Project GLUT專案 設定 libglut32
source.zip 裡的檔案 ( glm.h , glm.c , transformation.c ) 加進week11_model資料夾
glm.h 放同目錄 (桌面的week11_model資料夾)
glm.c 改檔名成 glm.cpp 並加入專案 Project, Add files, glm.cpp加入
transformation.c 的程式碼放到 main.cpp (原本的全部刪掉)
把data資料夾放入 C:\Users\Administrator\Desktop\freeglut\bin
改寫程式碼 做出自己的3D模型
#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 我的3D模型");
glutDisplayFunc(display);
glutMainLoop();
}
