Screening Log

Thursday, December 31st, 2015

It was very fortunate that I had many opportunities to have my video pieces screened at international events this year. Here I list the events as far as I can recall as my record. Huge thanks again to everyone who made all these happen.

Locus of everyday life and/or nemumel were invited and screened at:

Transform feedback in OF 0.9.0 – looping feedback

Sunday, December 27th, 2015

Following up with the last post answering the question I was asked several times – to keep updating the same attribute, e.g. vertex positions with transform feedback, you can use ping-pong technique to create a sort of feedback loop. Prepare two Buffer Objects, or ofBufferObjects for each shader attribute you want to update with feedback transform, then swap them every frame so that the updated buffer becomes the next input while the other becomes the next receiver of the output.

See the code snippets below. The complete example is on GitHub.

.h file
int currentAttributeBuffer = 0;
ofBufferObject positionBuffers[2];

.cpp
int feedbackTargetBuffer = 1 - currentAttributeBuffer;
vbo.setVertexBuffer(positionBuffers[currentAttributeBuffer], 4, 0); // Set one of the ofBufferObject as an attribute for the vertex shader
glBindBufferBase(GL_TRANSFORM_FEEDBACK_BUFFER, 0, positionBuffers[feedbackTargetBuffer].getId()); // Set the other ofBuffer as the target of the transform feedback
currentAttributeBuffer = feedbackTargetBuffer;

nu.it album info

Saturday, August 2nd, 2014

If the delicate music pieces have caught your interest, check out more tracks from the Album, nu.it at Basukaru’s label site. The album is available via mail orders and record stores. If you luckily live in Japan, there are more local stores you can just go and get one.

“The “field” of experimental ambient music (if there is such a thing) needs Sawako’s delicate, measured, expansive touch. We connoisseurs yearn for it. Sadly, the woman who describes herself as a “sound sculptor” and a “signal alchemist” is so busy – think of her audio-visual installation at the planetarium of the Sonar Festival or her numerous live performances, including an appearance on Ryuichi Sakamoto’s radio show – that we simply had to wait. This time, the waiting lasted six years before we could put our ears on a follow-up to her exquisite 12k release Bitter Sweet. And, of course, nu.it is well worth the wait.”
