week11~CCC

把data.zip的data/???obj檔用Notepad++打開來研究,並且知道意思。
#include <Gl/glut.h>
#include "glm.h"
GLMmodel * model=NULL;

void display()
{
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    if(model==NULL) model = glmReadOBJ("data/Al.obj");
    glmUnitize(model);
    glmFacetNormals(model);
    glmVertexNormals(model,90);
    glmDraw(model, GLM_SMOOTH | GLM_MATERIAL);

    glutSwapBuffers();
}
int main(int argc, char**argv)
{
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_DOUBLE |GLUT_DEPTH);
    glutCreateWindow("week11親手打造的");

    glutDisplayFunc(display);

    glutMainLoop();
}
