Nick deMarco - Problem Set #1
 
Part 1
p1.dbn 
// a carefully chosen line
paper 50
pen 100
line 0 50 100 50

Create a program to draw a carefully chosen one line on a paper of your choice.
 
Part 2
p2.dbn 
// This program uses one var							
// as a means to control a set 							
// of 3 lines. capture 3 instances							
// (a,b,c)										
//										
paper 50										
pen 100										
set x 50										
line 0 (x-50) 100 (x+50)								
line (x-50) 100 (x+50) 0								
line x 0 x (x+50)

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 
// This program draws a single
// filled rectangle.
//
paper 0
pen 100
repeat a 5 80
{
 line a 75 a 90
}

Create a program to draw a single filled rectangle. Again, choose carefully.
 
Part 4
p4.dbn 
// This program draws a single
// filled triangle.
//
Paper 0
Pen 100
repeat a 0 30
{ line (22+a) (35+a) (82) (35)
}

Create a program to draw a single filled triangle. Use your good judgement.
 
Part 5
p5.dbn 
// single filled triangle
paper = 0
pen = 100
repeat a 20 80
{
 repeat B 20 (a-1)
 {
  set [a B] 100
 }
}

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 
// This program evokes an emotion
// using five dots.
// {A SMILE => HAPPY}
Paper 0
set [50 50] 100
set [53 51] 100
set [47 51] 100
set [54 53] 100
set [46 53] 100

Set 5 dots on a paper of your choice. Evoke an emotion with your choice in placement of dots.
 
Part 7
p7.dbn 
// This program creates
// a picture of a person
// using 6 dotted lines
paper 0
// left leg
repeat a 0 5
{
  set b (50 - 2*a) 
  set c (50 - 4*a) 
  set [b c] 100
}
// right leg
repeat a 0 5
{
  set d (52 + 2*a)
  set e (50 - 4*a)
  set [d e] 100
}
// body
repeat a 1 5
{
  set f (50 + 5*a)
  set [51 f] 100
}
// right arm
repeat g 0 3
{
  set h (53 + 3*g)
  set i (65 + 4*g)
  set [h i] 100
}
// left arm
repeat j 0 3
{
 set k (47 - 3*j)
 set l (65 + 4*j)
 set [k l] 100
}
// head
repeat m 0 4
{
 set n (49 + m)
 set [n 75] 100
}
set [51 77] 100

Create a representational picture (i.e. something that looks like something) using just 8 (at maximum) dotted lines.
 
Part 8
p8.dbn 
paper 0
pen 100
repeat a 0 100
{
   repeat b 0 100
   {
      set [a b] b
   }
}

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 0
pen 100
repeat b 45 80
{
repeat n 1 80
{
smaller? n 50
{
set[(b-40) (n+(b-40)-1)] n
set[(b-10) (n+(b-40)-1)] n
set[(b+15) (n+(b-40))] n
}
}
}

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 = 0
pen = 100
set y 2
set z 0
set q 5
repeat x 1 9
{
set h q
set q (q+10)
set y (x*10)
set z (x*15)
repeat a y z
{
   repeat B 10 (a-1)
   {
      set [a b] (h+5)
   }
}
}

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