Exercise: OpenGL Transformations 2D (Solar System)

EX_OPENGL_TRANSFORMATIONS_SOLAR

• Create an OpenGL/SFML project

Part A

1. Draw a large yellow disk at the centre of the screen, representing the Sun.
2. Compile and Execute.

Part B

1. Modify the code in part A to all a smaller blue square ('Earth') a distance away from the 'sun'.
2. Animate the scene to have the Earth orbit the sun.
3. Compile and Execute.

Part C

1. Modify the code in part B to have the Earth spin on its own axis.
2. The Earth should spin 365 times for every orbit of the Sun.
3. Compile and Execute.

Part D

1. Modify the code in part C to add a small grey triangle('Moon') orbiting close to the 'Earth'
2. The Moon should spin around the Earth once for every 28 spins of the earth.
3. Compile and Execute.

Part D

1. Modify the code in part D to add a red pentagon('Mars') orbiting the Sun a little further out.
2. Mars has two small moons, add these as pixels. Have them rotate about mars.
3. Compile and Execute.
