Sliced Kiwi

Compose a graphic of a sliced kiwi fruit.

Kiwi Seed

In our graphic, the small seeds of the kiwi are distributed in two rings. They are dark (the color is already defined in SEED_COLOR) and have an elliptical shape (about 2/3 as wide as long).

Implement the kiwi_seed function. Use ellipse.

Sliced Kiwi Base

Compose a sliced kiwi without any seeds and without the core. Use the given colors for the brownish skin (SKIN_COLOR), and the greenish flesh (FLESH_COLOR). The kiwi should have the given overall diameter and the flesh should be 95% of that diameter.

Ring of Seeds

Create a function ring that produces a ring of count seeds, evenly spread across the 360 degrees of a circle. The inside diameter of the ring should correspond to diameter (the seeds should form a ring just outside the diameter). Repetitively call kiwi_seed to produce the ring of seeds.

Hint: If you need help, check out the Sliced Pitaya activity.

Ring of Triangles

The inside of a kiwi, around the seeds, is slightly darker. We can compose this darker area using two rings of triangles.

Each ring consists of isoceles triangles with the given side length and a 20 degree angle.

Before creating a ring, implement the kiwi_triangle function to construct a single triangle.

Insight: To create a ring of triangles we can use the ring function we originally wrote to create seed rings. It doesn't really matter what graphic we repeat in the ring: a seed, or a triangle, or anything else! This is great code reuse!

Here is a ring consisting of 12 triangles, with a ring diameter of 50 and a triangle side length of 25:

Sliced Kiwi

Now we have all the ingredients for our sliced kiwi. The kiwi consists of the sliced_kiwi_base, two rings of kiwi_triangles, two rings of kiwi_seeds, and a core circle.

Each seed ring is composed of 24 seeds, with a seed diameter of 5% of the kiwi diameter:

• ring diameter: 30% of kiwi diameter
• ring diameter: 45% of kiwi diameter

Each triangle ring is composed of 12 triangles and has a ring diameter of 25% of the kiwi's diameter:

• side 20% of the kiwi's diameter, rotated by 1/24 a triangle's angle
• side 25% of the kiwi's diameter

Place all rings on top of the kiwi base, and place a core circle (with 25% of the kiwi diameter) on top.
