 Week13裁切Modle

開啟maya匯入模型file->import 桌面model_obj

選取要匯出的部位file->export selection，存成OBJ檔

#include <stdio.h>

#include <GL/glut.h>

#include "glm.h"

GLMmodel * head = NULL;

GLMmodel * body = NULL;

GLMmodel * uparmR = NULL;

GLMmodel * iowarmR = NULL;

FILE * fout = NULL;

FILE * fin =NULL;

float teapotX=0, teapotY=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        if(body==NULL){

            body = glmReadOBJ("model/body.obj");

            glmUnitize(body);

        }

        glmDraw(body, GLM_MATERIAL);

    glPopMatrix();

    glutSwapBuffers();

}

GLMmodel * head = NULL;

GLMmodel * body = NULL;

GLMmodel * uparmR = NULL;

GLMmodel * lowarmR = NULL;

FILE * fout = NULL;

FILE * fin =NULL;

float teapotX=0, teapotY=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glScalef(0.2, 0.2, 0.2);

        if(body==NULL){

            head = glmReadOBJ("model/head.obj");

            body = glmReadOBJ("model/body.obj");

        }

        glmDraw(head, GLM_MATERIAL);

        glmDraw(body, GLM_MATERIAL);

    glPopMatrix();

    glutSwapBuffers();

}

將原來的keyboard函式註解掉並改為以下的程式碼

GLMmodel * head = NULL;

GLMmodel * body = NULL;

GLMmodel * uparmR = NULL;

GLMmodel * lowarmR = NULL;

int show[4] = {0, 1, 2, 3};

void keyboard(unsigned char key, int x, int y){

    if(key=='0') show[0] = !show[0];

    if(key=='1') show[1] = !show[1];

    if(key=='2') show[2] = !show[2];

    if(key=='3') show[3] = !show[3];

    glutPostRedisplay();

}

FILE * fout = NULL;

FILE * fin =NULL;

float teapotX=0, teapotY=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glScalef(0.2, 0.2, 0.2);

        if(body==NULL){

            head = glmReadOBJ("model/head.obj");

            body = glmReadOBJ("model/body.obj");

            uparmR = glmReadOBJ("model/uparmR.obj");

            lowarmR = glmReadOBJ("model/lowarmR.obj");

        }

        if(show[0]) glmDraw(head, GLM_MATERIAL);

        if(show[1]) glmDraw(body, GLM_MATERIAL);

        if(show[2]) glmDraw(uparmR, GLM_MATERIAL);

        if(show[3]) glmDraw(lowarmR, GLM_MATERIAL);

    glPopMatrix();

    glutSwapBuffers();

}

GLMmodel * head = NULL;

GLMmodel * body = NULL;

GLMmodel * uparmR = NULL;

GLMmodel * lowarmR = NULL;

int show[4] = {0, 1, 2, 3};

void keyboard(unsigned char key, int x, int y){

    if(key=='0') show[0] = !show[0];

    if(key=='1') show[1] = !show[1];

    if(key=='2') show[2] = !show[2];

    if(key=='3') show[3] = !show[3];

    glutPostRedisplay();

}

FILE * fout = NULL;

FILE * fin =NULL;

float teapotX=0, teapotY=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glScalef(0.2, 0.2, 0.2);

        if(body==NULL){

            head = glmReadOBJ("model/head.obj");

            body = glmReadOBJ("model/body.obj");

            uparmR = glmReadOBJ("model/uparmR.obj");

            lowarmR = glmReadOBJ("model/lowarmR.obj");

        }

        if(show[0]) glmDraw(head, GLM_MATERIAL);

        if(show[1]) glmDraw(body, GLM_MATERIAL);

    glPushMatrix();

        glTranslatef(teapotX, teapotY, 0);

        if(show[2]) glmDraw(uparmR, GLM_MATERIAL);

    glPopMatrix();

    if(show[3]) glmDraw(lowarmR, GLM_MATERIAL);

    glPopMatrix();

    glutSwapBuffers();

}

int oldX = 0, oldY = 0;

void motion(int x,int y)

{

    teapotX += (x - oldX)/150.0;

    teapotY += (y - oldY)/150.0;

    printf("glTranslatef(%f, %f, 0;\n",teapotX, teapotY);

    glutPostRedisplay();

}

void mouse(int button, int state, int x, int y)

{

    if(state==GLUT_DOWN){

        oldX = x;

        oldY = y;

        ///angle = x;

    }

    display();

}

最後修改glutMotionFunc(motion);
