week10 使用3D模型

 week10

先從jsyeh.org的3dcg10下載老師的範例

老師的網站網址(https://jsyeh.org/3dcg10/)

下載data win32

1.將window解壓縮並將data丟到window裡

2.開啟Transformation.exe

3.下載source.zip

4.把glm.h和glm.c拉到week10_glm(glm.c改名為glm.cpp)

#include <stdio.h>

#include "glm.h"

GLMmodel * pmodel = NULL;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    if(pmodel==NULL){

        pmodel = glmReadOBJ("Al.obj");

        glmUnitize(pmodel);

        glmFacetNormals(pmodel);

        glmVertexNormals(pmodel ,90);

    }

    glmDraw(pmodel , GLM_MATERIAL);

    ///glutSolidTeapot(0.3);

    glutSwapBuffers();

}

int main(int argc, char**argv)

{

    glutInit( &argc, argv );

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week10");

    glutDisplayFunc(display);

    glutMainLoop();

}

最後圖形

鋼彈模型

新開一個GLUT專案，week10_glm_gundam

將glm.h、glm.c(記得檔名改成glm.cpp)放在week10_glm_gundam目錄裡

#include <stdio.h>

#include "glm.h" ///下載 source.zip有glm.h放在week10_glm_gundam目錄裡

///glm.c改檔名成glm.cpp放在week10_glm_gundam目錄裡

///把glm.cpp加到專案裡

///把模型(ex. Al.obj A.mtl)複製到工作目錄

///再把Gundam.obg Gundam.mtl Diffuse.jpg放到工作目錄

GLMmodel * pmodel = NULL;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    if(pmodel==NULL){

        pmodel = glmReadOBJ("Gundam.obj");

        glmUnitize(pmodel);

        glmFacetNormals(pmodel);

        glmVertexNormals(pmodel ,90);

    }

    glmDraw(pmodel , GLM_MATERIAL);

    ///glutSolidTeapot(0.3);

    glutSwapBuffers();

}

int main(int argc, char**argv)

{

    glutInit( &argc, argv );

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week10");

    glutDisplayFunc(display);

    glutMainLoop();

}
