draw 3d objects in opengl

,

Introduction

We have already applied textures to objects in the  post-obit article.

• 3D Planetary System In OpenGL

Here, we will but describe some scene using QUADS. Starting time, configure Visual Studio for glut. Read the following article to configure Visual Studio for overabundance and to go started with OpenGL.

• Getting Started with OpenGL In Visual C++

For applying textures, we need textures image (256*256) 24 bit bitmap files.

Here's the scene graph paradigm that I have drawn.

Coding

I have created the post-obit files in the project.

• 3D_GameScene_OpenGL.cpp
• DisplayScene.h
• DisplayScene.cpp
• LoadImageFile.h
• LoadImageFile.cpp
• DrawScene.h
• DrawScene.cpp

3D_GameScene_OpenGL.cpp

This is the main source file where I have defined a principal() function.

DisplayScene.cpp

In this file, I have used a switch example statement to draw scenes by providing unlike texture image files as arguments to it. I have declared course and data in DisplayScene.h header file.

LoadImageFile.cpp

This file contains a function that applies the texture to the drawn objects.

DrawScene.cpp

In this file, I have drawn a scene or defined the function which are declared in DrawScene.h header file.

Come across the code divers in the in a higher place files.

DisplayScene.h

1. #ifndef _DISPLAYSCENE_H
2. #define _DISPLAYSCENE_H
5. enum  MyTextures
6. {
7.     DEFAULT = 0x01,
8.     ANIMATION=0x02,
9.     BUILDINGS=0x03,
10.     HORROR=0x04,
11.     GREENY=0x05,
12.     WOODS=0x06,
13.     ROCKS=0x07,
14.     CIRCUIT=0x08
15. };
19. class  DisplayGameScene
20. {
21. public :
26. static void  DisplayTexturedGameScene( int , int , BOOL );
27. };
