Special Shapes

Circle

makeCircle()

Creates a Shape containing vertices resembling a circle

Arguments:

• Vector center
• integer radius
• double/float angle. ** In radians ** multiplied by pi ** somewhat helps with determining resolution.

Implementation:

x = radius * cos(angle);
y = radius * sin(angle);

where theta is incremented by angle to create circle. Inserted Vectors will be shifted by center values.

Notes:

• Not sure if calculating for only one quadrant and using negatives for the rest is faster or worth the time saved.
• Still need to determine a resolution for circles.

Rectangle

makeRect()

Makes a Shape containing vertices in the shape of a rectangle

Arguments:

• Vector corner (bottom left)
• int width
• int height

Implementation:

clockwise insert of 4 points. corner, corner + (0,height), corner + (width,height), corner + (width,0)

Notes:

Squares will just use makeRect();
