Concrete Tri&Line

Posted on November 24, 2011 by cyberoblog

In the process of being made.

A structural render of a concrete loop using a short midi remix.

__kernel void CubeRootWave(__global const float4 *src, float frequency, float amplitude, float phase, __global float4 *dst) { // Get the thread id used to differentiate each execution of the kernel int tid = get_global_id(0); // Get the vertex float4 vertex = src[tid]; // Add a cbrt wave to the vertex y component vertex.y += cbrt(vertex.x * frequency + phase) * amplitude; // Write out the new vertex position dst[tid] = vertex; }

Concrete Tri&Line

The audio generated from the midi file being run by the concrete music voices produces a range of frequencies that are then fed into an OpenCL kernel that is a trivially modified version of the SinWave kernel that ships as the default Mesh Animation example. This and other similarly trivial modified kernels feed into Triangle Mesh Creator and Line Mesh Creator patches that output their result to a GL Tools Structure Renderer wrapped Mesh Renderers.

Further modifying of the x , y and z vertices can also be quite easily accomplished resulting in such a thoroughly dynamic structural mesh animation.

Other skeleton frameworks can easily be switched.

Showing the disparate rendering engine behaviour with HTML 5 markup, using the test case posted to gitbub by adactio – Illustration of sectioning content and the outline algorithm in HTML5. Screen captures of the slightly different rendering engine’s results layered up in GIMP, each layer is juxtaposed at its top left hand corner , the ‘T’ in ‘This is an H1′. From that point onwards, the three engine’s diverge.

A fresh start on a new hosting provider’s domain

Posted on November 13, 2011 by cyberoblog

Today, Just_A_QC_Blog begins afresh , with the entirety of cybero’s web presence , including this blog, hosted anew by site5.

Having suffered the difficulties created by uk2.net’s dysfunctional systems – payment systems, support systems, cancellation systems, all have failed me too often, no surprise that finally my patience failed with uk2 [gripes aplenty for them http://cybero.co.uk/Just_A_QC_Blog/?p=837].

Following a suggestion from a friend and acquaintance of mine [thanks Steve Adams of http://threestreams.co.uk/ ] I took the plunge and haven’t regretted the decision to switch to site5. One of the main differences I found was that the online support was pertinent, practical and very straight from the shoulder, without any hint of conceit or condescension from the support personnel. What a refreshing change – people that really knew how their systems worked and had no need nor sought any recourse to obfuscation.

OpenCL & Quartz Composer

Posted on November 13, 2011 by cyberoblog

Just been experimenting with structures, OpenCL and making that slightly awkward OpenCL Convertor patch do some of what it does so well with some rough, raw and responsive results.

Have just posted the results of my excursions up to Vimeo and YouTube, the more geeky screen recordings are on YouTube

http://www.youtube.com/user/cyberoproductions#g/c/29E2D735258D0D7F

the eye candy stuff is up on Vimeo. Structure to Image, Image to Structure, Structure to line, Structure to 3D, Point Structures.

OpenCL Image Conversions

Turning Image to Structure and Structure to Image, with , of course any number of intervening modifying processes, enables the rendering of an infinite variety of Quartz Image and Quartz 3D Mesh

Using the Quartz Crystal CLI

Posted on November 13, 2011 by cyberoblog

CLI = Command Line Interface – curiously enough, even with an application so heavily skewed towards the GUI based production of offline rendered dynamic graphics and animations as Quartz Crystal is, it’s well and truly capable of working well from a CLI based approach.
