劉 電腦圖學 week8

 week08 3D模型

第一堂課

前往https://jsyeh.org/3dcg10/ 下載source deta win32

 

 v 對應 vertex頂點

vt對應 貼圖座標 glTexCoord2f(tx,ty)

vn 對應vertex normal法向量

f 對應 面facet

第二堂課 

開啟glut專案 week08-1

#include <GL/glut.h>

#include "glm.h"

void display()

{

    glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );

    glutSolidTeapot( 0.3 );

    glutSwapBuffers();

}

int main(int argc, char* argv[])

{

  glutInit(&argc, argv);

  glutInitDisplayMode(GLUT_RGB|GLUT_DOUBLE|GLUT_DEPTH);

  glutCreateWindow("week08");

  glutDisplayFunc(display);

  glutMainLoop();

}

把glm.h加進week08-1的目錄

將glm.c改名為glm.cpp 加入week08-1目錄

add檔案到week08-1

#include <GL/glut.h>

#include "glm.h"

GLMmodel *pmodel = NULL;

void display()

{

    glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );

    if(pomdel==NULL) {

         pmodel = glmReadOBJ("Gumdan.obj");

         glmUnitize(pmodel);

    }

    glmDraw(pmodel, GLM_SMOOTH | GLM_MATERIAL);

     glutSolidTeapot( 0.3 );

    glutSwapBuffers();

}

int main(int argc, char* argv[])

{

  glutInit(&argc, argv);

  glutInitDisplayMode(GLUT_RGB|GLUT_DOUBLE|GLUT_DEPTH);

  glutCreateWindow("week08");

  glutDisplayFunc(display);

  glutMainLoop();

}

第三堂課

開啟新專案 week08-2 _glm_model_texture

將08-1貼上

安裝opencv

#include <GL/glut.h>

#include "glm.h"

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_SMOOTH | GLM_MATERIAL);

    glutSwapBuffers();

}

int main(int argc, char* argv[])

{

  glutInit(&argc, argv);

  glutInitDisplayMode(GLUT_RGB|GLUT_DOUBLE|GLUT_DEPTH);

  glutCreateWindow("week08");

  glutDisplayFunc(display);

  glutMainLoop();

}

#include <GL/glut.h>

#include "glm.h"

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_SMOOTH | GLM_MATERIAL);

    glutSwapBuffers();

}

int main(int argc, char* argv[])

{

  glutInit(&argc, argv);

  glutInitDisplayMode(GLUT_RGB|GLUT_DOUBLE|GLUT_DEPTH);

  glutCreateWindow("week08");

  myTexture("Diffuse.jpg");

  glutDisplayFunc(display);

  glutMainLoop();

}
