Part One: Analysis of Turtle Art Gallery Art Piece
For the analysis and recreation of Turtle Art, I chose the drawing Spires from the Turtle Art Gallery. In order to remake the drawing, I have to decompose it and analyze it first. In this drawing, there are two main components/sub-procedures: the back ground and the spires.
Because the Spires is “on top” of the blue background (the other way to see it is that you can’t see stars on top of the Spires), the sequence of this drawing should be CLEANà BACKGROUNDàSPIRES.
The background include a FillScreen block to filling the whole screen with a deep blue color around 70. Then, I can draw the stars. First of all, because the stars were different sized, so I can use a random block to set a random pen size each time I draw a star. Then, to make the stars spread out randomly, I can use repetition block to assign random x and y-values.
Because the spires on the right always covers up the spires on its left, so I can assume that the whole roll of spires can be drawn from left to right by using a repetition block.
The most interesting part of this drawing is how each individual spires is drew because there pattern, sizes, even shape in some extend are different from each other. Because an individual spire contained multiple circles, I could assume that an individual spire can be drawn by using an incrementing pattern on pen size from the top to the bottom, and a random shading to make them black, white, and grey. Then, a repeat block is used to set a random X and Y-value for the top of the spires, and drew them from the left side to the right side of the screen.
Part Two: Recreation of Art Piece
In this part, I remade the art piece Spires from the Turtle Art Gallery with some adjustments. First of all, I changed the incrementing pattern of each individual Spire. Because personally I dislike how the bottom of the original spire looks to “fat”, I limited the size of the spires by setting the pen size randomly between 5 and 30.
Then, I set a random color pattern to my creation, and I found out that the colors are too random. So I used an increment block instead of a random block, and I found out that if I increased/decreased the color a bit from the original color when drawing each circles, the color would look less random.
Because the final product looked like coral reefs, I decided to add some bubbles on the back ground to make the drawing looks like an under-sea world. I added a circle with random sizes, random color and random shadings limited in a set range to display bubbles, and it worked out pretty well. Then, I used repetition block to duplicate the circles with random X and Y-values for 90 times, so that it will randomly fill the screen.
Part Three: Inspirations and Plan
I recently found the drawing The Great Wave off Kanagawa by Japannesse artist Hokusai in the 1830s. I really like the way Hokusai drew the waves, and I would like to make some adjustments and recreate part of this drawing.
(Block Sky, Block Cloud)First of all, I divided the drawing up to two parts and made separate adjustments. The first part of the drawing is the background, or the sky in the far end of the drawing. I would first fill the screen with an orange color around 15 and give it a dark shading, and then I would make some adjustments and add the clouds. Because I can’t make the complexed shaped cloud on the back, I would use random and repetition blocks to drew another kind of cloud that’s often seen in many traditional Japanese drawings. (add a pic)
Afterword, I would focus on drawing the two kinds of wave shown below.
The first one(the one on the left) would be on the lower side of my drawing, covering my drawing in the lower and the middle right part of the drawing. It would contain two kinds of lines to display the waves in the original drawing, and the white part on the top to display the white tip of the waves in the original drawing. The second one(the one on the right) would be on the back of the first one, displaying the very small, flower like parts of the wave.
(Block Wave 2)First of all, I’ll drew the second type of wave, because it’s on the back of the first type of wave. I will drew some lines on an arc like shape filled with light blue color. On the type of those waves, I’ll drew the flower like parts of the wave.
(Block Wave 1)For the first kind of wave, there are a deep blue color and a light blue color, so I will fill an area with light color and drew deep blue lines using the arc block to represent the waves. For the white tips of the wave, I will drew triangles with arc as sides.
Part Four: Final Product and Reflection
In my final product, I only completed the first kind of wave and the clouds on the background. This is partially because I spent too much time on trying to drew the white tips using a random pattern, but continually failed to do it. I did finished my background and the clouds on it, and it looked ok to me.
One of the many struggle I faced is how to fill a shape. Originally I thought to fill a shape you have to draw a closed-up figure with no opening sides. So I ended up spending the majority of the time trying to figure out a way to try to drew the triangular light blue shape on the background, since I need to tell the turtle to go forward exactly how many step to drew the hypotenuse side, and Turtle Art contain demoes. Then, I find out Turtle Art can automatically complete the shape and fill it. This really made me feel very bad at the end of the day.
