Introduction

Introduction

• Google Earth is a virtual globe, map and geographical information program .

• It displays satellite images , 3D Buildings ,map ,street view of the Earth's surface

Introduction

• Satellite images of the Moon and Mars.

• Shows information about constellations and other space sights visible

Introduction

• I try to create my solar system like google earth !!!

• But It’s difficult.

Technology

• Use skill that learned in CG class.• Use OpenGL with glut.• Use texture to draw surface of plant.• Enable light • Enable RGBA • Draw Solar system according to real Scale

model – But not precise – Because some plant will be too small.

Technology

plant Diameter Distance

Sun 44.6 m (146 ft) 零

Mercury 15 cm (6) 1.9 公里 (1.2 mi)

Venus 38 cm (15) 3.5 公里 (2.2 mi)

Earth 41 cm (16) 4.8 公里 (3.0 mi)

Moon 10 cm (4) 12 m (40 ft) 從地球

Mars 23 cm (9) 7.2 公里 (4.5 mi)

Jupiter 4.55 m (15 ft) 24.9 公里 (15.5 mi)

• Scale model of Solar system
