Part 1
p1.dbn
paper 50
repeat a 20 80
{
set [a 65] a
}


Create a program to draw a carefully chosen one line on a paper of your choice.
 
Part 2
p2.dbn
paper 0
set a 20
pen a
line a a (2*a) (2*a)
line (20+a) (60-a) 60 20
line 20 20 60 a



Create a program that uses one variable as a means to control a set of 3 lines. Capture 3 instances of the graphic (A,B,C).
 
Part 3
p3.dbn
paper 100
repeat a 10 80
{
pen a
line a (a+10) (a+10) a

}




Create a program to draw a single filled rectangle. Again, choose carefully.
 
Part 4
p4.dbn
paper 2
repeat a 10 90
{
pen a
line 50 40 a 20
}


Create a program to draw a single filled triangle. Use your good judgement.
 
Part 5
p5.dbn
paper 100
pen 1
repeat a 15 90
{
line a a 20 50
}





Think of all the ways you can draw a filled triangle, and choose one. Utilize the properties of the drawing method you choose, to create a single filled triangle.
 
Part 6
p6.dbn
paper 40
set [20 50] 100
set [30 50] 100
set [25 45] 100
set [23 20] 100
set [35 88] 100


Set 5 dots on a paper of your choice. Evoke an emotion with your choice in placement of dots.
 
Part 7
p7.dbn
paper 1
repeat a 20 40
{
set [(2*a) 20] 100
set [(2*a) 80] 100
}

repeat a 10 40
{
set [40 (2*a)] 100
set [80 (2*a)] 100
}
repeat a 18 42
{
set [(2*a) 16] 100
set [(2*a) 84] 100
}
repeat a 8 42
{
set [36 (2*a)] 100
set [84 (2*a)] 100
}

Create a representational picture (i.e. something that looks like something) using just 8 (at maximum) dotted lines.
 
Part 8
p8.dbn
paper 1
repeat a 1 100
{
repeat b 1 100
{
set [(a*a/b) (b*b/a)] ((a+b)/2)
}
}



Using a nested loop, fill the entire field with the value of some calculation that can be appreciated. Do not use the Line command.
 
Part 9
p9.dbn
paper 1
repeat a 0 13
{
repeat b 0 16
{
repeat c 0 7
{
set [(2*a*c) (3*b*c)] (c*14)
}
}
}


Using a nested loop, create a stippled pattern of dots that can be enjoyed for its complexity. Do not use the Line command.
 
Part 10
p10.dbn
paper 1
repeat a 0 50
{
repeat b 0 50
{
pen ((a+b)/2)
line a b (2*a) (2*b)
}
}



Using the Line command, and a (few) nested loop, create an image that evokes a three-dimensional feeling through shading.
