#OpenGL Amusement Park This project, “An Amusement Park” aims at drawing a virtual amusement park. The park includes objects like Giant Wheel, Columbus and Roller Coaster. Giant Wheel is visualized using circular rings. Rotation effects are provided for Giant Wheel. Swinging action is employed for Columbus ship. The Roller Coaster moves on a specified track. The tracks are created using Bezier curve functions with a set of defined control points. The whole scene is placed inside a texture mapped cube called SkyBox. This gives a realistic sky effect. The software also includes a first person movement where the viewer can move around anywhere in the scene. Mouse drag for rotation is supported. The mouse context menu helps the user in selecting various options. The colours of various objects can be changed. The SkyBox texture background can be changed. The user can control various camera positions like, Free Movement, On Roller Coaster, On Columbus ship and In Giant Wheel. The user will also be able to control the movement of individual objects. Objects like cube, sphere and cylinders are used to implement 3D objects. Plain lines are used in the construction of Roller Coaster track. The normal, tangent and binormal at every point on the curve is calculated and the Roller Coaster is properly oriented along the track by rotating it about the angles made by tangent, normal and binormal with the curve. The following options are supported: • Navigate in the scene. Rotate 360 degree to view. • Start and stop Giant Wheel rotation, Columbus swinging action and Roller Coaster movement. • Change colours of Giant Wheel, Columbus ship and Roller Coaster. • Change background of SkyBox.
