Projection Design

“Projection Design” offers a hands-on approach to the design, planning and execution of digital projections in a variety of performance spaces by using a combination of industry standard and open source research software tools. This blog will serve as an online text for the developing book, "Technical Ecstasy" and link for the web-readings, online tutorials,software resources historical examples, video art and performance examples and essential class communications for Projection Design class taught by Patrick Pagano

HAP Codec & Syphon

HELLO,

Basically, my research and knowledge of these two open source programs consists of what I've found on their websites. After trying to put in my own words what they meant, I figured I would just highlight (copy and paste) the most important points 2 me. I don't think I could explain it any better than the guys who developed it can so I've tried doing my best to find the main objectives of each software.

HAP Codec 
http://vdmx.vidvox.net/blog/hap
http://vdmx.vidvox.net/tutorials/using-the-hap-video-codec 

"A new video codec designed for digital video artists and Mac VJs with the goal of achieving higher performance video playback in OpenGL-based applications”
 “The main benefit of Hap is a greatly reduced CPU load during movie playback.”  
 “…(producing) good quality images.”
 3 Different Hap codecs:
            Hap has the lowest data-rate and reasonable image quality
            Hap Alpha has similar image quality to Hap, and supports an Alpha channel.
            Hap Q has improved image quality, at the expense of larger file sizes.


 Syphon 
http://syphon.v002.info/ 

“An open source Mac OS X technology that allows applications to share- full frame rate video or stills – with one another in real time.”
·      Hardware accelartion on the GPU
·      Alpha-channels
·      Ever-growing number of Syphon-enabled applications
·      A simple SDK so syphon can be added to just about any application
