(OwO)電腦圖學week10_4/26

安裝freeglut (libglut32.a),OPenCV2.1(Add PATH)

File-New-Project-GLUT(重開CodeBlocks)

把上週&上上周的 my Texture.txt 和 10行GLUT程式碼拿來用

#include <opencv/highgui.h>

#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cv.h)

    glEnable(GL_TEXTURE_2D);///開貼圖功能

    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;

}

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_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week09 texture");

    glutDisplayFunc(display);

    myTexture("sky.png");

    glutMainLoop();

}

openCV設定:setting

• Include：Compiler，Add C:\opencv2.1\include
• Lib：Linker，Add C:\opencv2.1\lib
• Linker settings，Add cv210、cxcore210、highgui210
