Week10

step01

開啟連結 https://jsyeh.org/3dcg10/

(windows.zip  下載 \ windows \ Texture.exe)

(data.zip  下載 \ windows \ data) 

解壓縮後將data資料夾拉到win32裡面

step02

打開CodeBlocks 

新增glut專案

將glm.c和glm.h移動

將glm.c改檔名為glm.cpp加到專案

step03

程式碼：

#include <GL/glut.h>

#include "glm.h"

GLMmodel * pmodel = NULL;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT);

    if(pmodel==NULL)

    {

        pmodel = glmReadOBJ("Al.obj");

        glmUnitize(pmodel);

        glmFacetNormals(pmodel);

        glmVertexNormals(pmodel,90);

    }

    glmDraw(pmodel,GLM_MATERIAL);

    glutSwapBuffers();

}

int main(int argc, char** argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode( GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week10");

    glutDisplayFunc(display);

    glutMainLoop();

}

step04

step05

複製 https://gist.github.com/jsyeh/5ed01210559721ec71b659b3ffed2dd7 的程式碼

step06

下載myTexture.cpp

程式碼：

#include <GL/glut.h>

#include "glm.h"

#include <opencv/highgui.h> ///使用 OpenCV 2.1 比較簡單, 只要用 High GUI 即可

#include <opencv/cv.h>

#include <GL/glut.h>

int myTexture(char * filename)

{

    IplImage * img = cvLoadImage(filename); ///OpenCV讀圖

    cvCvtColor(img,img, CV_BGR2RGB); ///OpenCV轉色彩 (需要cv.h)

    glEnable(GL_TEXTURE_2D); ///1. 開啟貼圖功能

    GLuint id; ///準備一個 unsigned int 整數, 叫 貼圖ID

    glGenTextures(1, &id); /// 產生Generate 貼圖ID

    glBindTexture(GL_TEXTURE_2D, id); ///綁定bind 貼圖ID

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT); /// 貼圖參數, 超過包裝的範圖T, 就重覆貼圖

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT); /// 貼圖參數, 超過包裝的範圖S, 就重覆貼圖

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST); /// 貼圖參數, 放大時的內插, 用最近點

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST); /// 貼圖參數, 縮小時的內插, 用最近點

    glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, img->width, img->height, 0, GL_RGB, GL_UNSIGNED_BYTE, img->imageData);

    return id;

}

GLMmodel * pmodel = NULL;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT);

    if(pmodel==NULL)

    {

        pmodel = glmReadOBJ("Al.obj");

        glmUnitize(pmodel);

        glmFacetNormals(pmodel);

        glmVertexNormals(pmodel,90);

    }

    glmDraw(pmodel,GLM_MATERIAL | GLM_TEXTURE);

    glutSwapBuffers();

}

int main(int argc, char** argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode( GLUT_DOUBLE | GLUT_DEPTH );

    glutCreateWindow("week10");

    glutDisplayFunc(display);

    glutMainLoop();

}
