Pure Data: Learning Synthesis

The Basics

To improve my understand on Pure Data, I began by exploring the basics of Pure Data by creating a simple patch.
Here I was able to construct a simple Synthesis, in the process I was able to learn what each individual attribute does within the synthesis. 

Firstly, an oscillator "osc~" was created with a frequency of 440Hz, this was then connected to an object that could hold a number "*~". Next, flowing downwards, a digital to analogue converter was added "dac~" this made it so sound could be heard from either left or right speakers (or both). I then integrated an array and named it "display", this would display a waveform from the sound being produced. Originally, a bang was integrated, which acted somewhat like a camera; taking snap shots of the waveform, but this was not efficient, so I created an object "tabwrite~" which writes output from osc to an array and integrated a metronome "metro (numeric value)" which continuously sends bangs (a toggle switches this on/1 or off/0).

Going back up to "*~", messages have been connected which hold numeric values, these control the amplitude of the sound, "*~" can basically hold a number value that is connected to it and selected. The values above "osc~ 440" control the frequency, when a new frequency is selected, it completely replaces the original value - the only way to return back to the original value, is to create a message that stores that value.

Pure Data: GEM

Image
Here I will be presenting my final project in Pure Data using GEM, and what I have learned from the experience of using pure data to create motion graphics. The code will be sectioned into separate processes and explain in the order 1 through 7 as shown in the figure below. Figure 1 Step 1: Created [gemwin] object and connected it to three messages; [create] creating a window to draw graphics to, [destroy] to terminate the window, [lighting] which would initiate the world lighting. A toggle were added to [gemwin] to start and pause graphics, and another toggle to lighting to switch on or off. Step 2: Next I created a [gemhead] to begin drawing graphics to the empty window, I start off by creating a 3D object; a cube, and defining some properties; its XYZ rotation, XYZ translation, and colour. Two messages; draw fill and draw line, were connected to the cube, which would either fill the render into a solid shape, or draw the rendered shape with out-lines. Step 3 & S...

Purr Data: GEM

-
Using the information provided by the source given that explained what GEM is and what it is used for in Pure Data, I now have a clear understanding on how GEM is used to create media visuals; images, videos, and 3D Shapes. What is GEM? GEM is based on a large part of OpenGL. GEM is apart of pure data, and it is used to create motion graphics, this includes videos or still images, draw 2D or 3D shapes, and transform objects and shapes. Visuals can also be made to react to sounds. [gemwin] [gemwin] is what represents the window a graphic is drawn into - it creates a window which displays the graphics created. Using frame-rate, it schedules when frames should be drawn to the screen, by default, it clears the window and sets a background colour using RGB values. [gemhead] [gemhead] is the start of a chain of graphics operations connected by patch cords, that should be executed ever frame. Drawing operations cascade from the top down - adding to each other, flowing downwards ...

The Enduring Ephemeral, or the Future Is a Memory

Written by Wendy Hui Kyong Chun The Enduring Ephemeral, or the Future Is a Memory This read discusses how new media, like computer technology, is constantly evolving yet simultaneously back-peddling towards what would be know as a "bleeding edge of obsolesce". Normally, I questioned "what is new media?", yet the author suggests more appropriate questions such as "what was new media?" and "what will new media become?"... The "new" in "new media" suggests that what is new will one day become old, however, this is not the case with new media; as new media is almost the same yesterday as it is today, as stated by the author. This leads me to assume, due to the constant  storing and evolution of new media, it could not possibly become old despite the age of any such media; as "old" media found today is rediscovered as "new" media, which is a constant cycle of repetition. I found this interesting, as archi...
