是我是我詐騙 Week11

 

🖨 3D模型 🖥

1.設定

source\ glm.h, glm.c, transformation.c 都放在專案的資料夾裡

glm.c =改名=> glm.cpp 用 Add File 放到專案裡

transformation.c 的程式放到 main 裡

2.把模型(data)放到freeglut\bin

3.製作自己的模型

程式碼如下:

#include "glm.h"           ///使用glm.cpp外掛

GLMmodel* pmodel = NULL;   ///pmodel指標

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_DEPTH | GLUT_DOUBLE);

glutCreateWindow("08160554");

    glutDisplayFunc(display);

  glutMainLoop();

}

4.打光

程式碼如下:

#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);

    glPushMatrix();     ///車子要轉180度

        glRotatef(180,0,1,0);

        drawmodel();

    glPopMatrix();

    glutSwapBuffers();

}

///打光
