做出3D模型
step1:老師的4個檔案-
windows.zip =解壓=> 桌面 \ windows \ transformation.exe
data.zip =解壓=> 桌面 \ windows \ data \ 桌面
source.zip =解壓=> 等下要寫程式 (建出 transformation)
glut32.dll =在windows裡面
step2: File-New-Project, GLUT專案 (把 freeglut準備好)
source.zip 裡: glm.h 放專案資料夾: 桌面 week11_model
transformation.c 複製內容到main.cpp裡,並Add File把 glm.cpp加入
成功跑出程式:
畫出保時捷
程式碼:
#include "glm.h" ///glm.cpp外掛
GLMmodel*pmodel=NULL; ///pmodel指標
GLMmodel*pmodel=NULL; ///pmodel指標
void drawmodel(void)
{ ///使用範例程式
if(!pmodel)
{
pmodel=glmReadOBJ("data/porsche.obj"); ///模型讀入
if(!pmodel) exit(0);
glmUnitize(pmodel);
glmFacetNormals(pmodel);
glmVertexNormals(pmodel, 90.0);
}
glmDraw(pmodel,GLM_SMOOTH | GLM_MATERIAL);
}
void display( )
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
drawmodel( ); ///使用範例程式
glutSwapBuffers( );
}
int main(int argc,char** argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("week11_08160023");
glutDisplayFunc(display);
glutMainLoop( );
}
打光part2
程式碼:
#include "glm.h"
GLMmodel*pmodel=NULL;
void drawmodel(void)
{
if(!pmodel)
{
pmodel=glmReadOBJ("data/porsche.obj");
if(!pmodel) exit(0);
glmUnitize(pmodel);
glmFacetNormals(pmodel);
glmVertexNormals(pmodel, 90.0);
}
glmDraw(pmodel,GLM_SMOOTH | GLM_MATERIAL);
}
void display( )
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glPushMatrix( );
glRotatef(180, 0,1,0);
drawmodel( );
glPopMatrix( );
glutSwapBuffers( );
}
const GLfloat light_ambient[ ] = { 0.0f, 0.0f, 0.0f, 1.0f }; ///打光陣列
const GLfloat light_diffuse[ ] = { 1.0f, 1.0f, 1.0f, 1.0f };
const GLfloat light_specular[ ] = { 1.0f, 1.0f, 1.0f, 1.0f };
const GLfloat light_position[ ] = { 2.0f, 5.0f, -5.0f, 0.0f };
const GLfloat mat_ambient[ ] = { 0.7f, 0.7f, 0.7f, 1.0f };
const GLfloat mat_diffuse[ ] = { 0.8f, 0.8f, 0.8f, 1.0f };
const GLfloat mat_specular[ ] = { 1.0f, 1.0f, 1.0f, 1.0f };
const GLfloat high_shininess[ ] = { 100.0f };
int main(int argc,char** argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("week11_08160023");
glEnable(GL_DEPTH_TEST); ///打光開始
glDepthFunc(GL_LESS);
glEnable(GL_LIGHT0);
glEnable(GL_NORMALIZE);
glEnable(GL_COLOR_MATERIAL);
glEnable(GL_LIGHTING);
glLightfv(GL_LIGHT0, GL_AMBIENT, light_ambient);
glLightfv(GL_LIGHT0, GL_DIFFUSE, light_diffuse);
glLightfv(GL_LIGHT0, GL_SPECULAR, light_specular);
glLightfv(GL_LIGHT0, GL_POSITION, light_position);
glMaterialfv(GL_FRONT, GL_AMBIENT, mat_ambient);
glMaterialfv(GL_FRONT, GL_DIFFUSE, mat_diffuse);
glMaterialfv(GL_FRONT, GL_SPECULAR, mat_specular);
glMaterialfv(GL_FRONT, GL_SHININESS, high_shininess); ///打光結束
glutDisplayFunc(display);
glutMainLoop( );
}
讀出鋼彈3D模型
step1:上方file選擇Open file打開資料夾
step4:Search directories >Link > 加入C:\\OpenCV2.1\lib
成功讀取鋼彈:數字鍵選擇"部位",英文鍵選擇"旋轉"
