Jain's 圖學筆記 #week11

 先去Moodle下載範例 source、windows、data

解壓縮windows再將data丟進去解壓縮

開啟GLUT將source內的 glm.h和glm.c丟入w11(目標資料夾)資料夾

將glm.c改成glm.cpp

複製transformation.c的程式碼貼到main.cpp

看開始 閃退就成功ㄌ

=========================

阿開始

先把main.cpp全刪

再打

#include "glm.h"
GLMmodel* pmodel = NULL;
void
drawmodel(void)
{
    if (!pmodel) {
pmodel = glmReadOBJ("data/flowers.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("08160333");
    glutDisplayFunc(display);
    glutMainLoop();
}

*將data抓到 freeglut/bin

打燈

}
