Drawing Butterflies and Hearts... USING ONLY CODE - Small Basic Featured Programs

UPDATES: Added Nonki's heart as Heart #3 on 2/13. Added Nonki's butterfly as Butterfly #3 on 2/11.

===========================

Check out our February Small Basic Coding Challenges from LitDev! Community challenges are from Math Man and Amir CPS.

 

Today we're going to look at two challenges and two programs from each challenge...

     

Small Challenge 2

Draw a picture of a butterfly.

  

The first Butterfly is from Math Man:

NDG956

 

 

Our second Butterfly comes from NaochanON:

LVF292

  

Our third Butterfly comes from Nonki Takahashi:

WXF823

Community Challenge 2 - By Amir CPS

(b) Draw a heart shape and calculate it's area.

 

This first Heart is from Nonki Takahashi:

SWQ275

Screen shot of a program Herart 0.1

 

Our second heart comes from NaochanON:

(  area...... r=r+dr,   dS= r*r*dθ/2   θ= 0 -2pi  ）

CFQ822 

 

Our third Heart is also from Nonki Takahashi:

SWQ275-3

 

Screen shot of a program Heart 0.2

The numerically-integrated area of the Heart Function was very near to pi (circular constant).

 

Our fourth Heart comes from Math Man (you have to import it and it run locally to get the input to work):

ZHP577-0

   

Thanks to everyone for the great contributions! What do you think? How hard is it to draw like this in Small Basic?

    It's pretty hard to draw shapes in Small Basic manually because you need coordinates and sizes and that involves much data. But then again, programmers are basically the people that handle data, so we're used to it. But this is just my opinion. I am 11 and am not very experienced so maybe someone else's opinion would be better.

    I think you should add Nonki's WXF823 @ smallbasic.com/program

    As I said, input does not work in silverlight. Were you referring to how it works in local Small Basic? If so, just press enter after typing input size.

    Gotcha. I updated the blog post to specify to run it locally. Thanks!
