PatchBox is becoming quite the powerful tool for architectural video mapping but sometimes even I miss a certain sense of immediacy that I’ve grown accustomed to from my years of VJ’ing.
It was with much delight then that I received a link from my old chum (and favourite Stylophone player) Tom Hume last week pointing me [...]
Am just ironing out a few minor niggles in PatchBox and creating a few extra scripts and shaders before we pack up for the event tomorrow.
The Eye-Sphere image is absolutely nothing to do with it, but it’s kind of strange…
The latter shows a cheap shadow shader effect I came up with that draws an offset [...]
While testing PatchBox with multiple monitors turned on, the CPU usage suddenly shot up to 95% for absolutely no reason at all.
Disabling the second monitor brought it down to less than 1% (where it should be!)
Using ProcessExplorer I saw that two threads were taking up all the time with very similar stacks:
ntkrnlpa.exe!KiUnexpectedInterrupt+0×121
ntkrnlpa.exe!ZwYieldExecution+0×1c8e
hal.dll+0×2ef2
nvoglnt.dll+0×25d20b
I remembered reading that [...]
PatchBox r281 with Relief Mapping
I’ve now replaced all the fixed-function rendering in PatchBox with CGFX shaders! This means that every pixel drawn to screen is now configurable - even in edit mode.
Also did some more work on my CGFX shader implementation, adding support for more semantics, and calculating bi-normals and tangents for the quads, which [...]
Video Billboard Test
For the city scape I’m working on we have a bunch of logos of the sponsors of the events, and a show reel to incorporate. The former are going to appear on billboards and on the sides of the rotating buildings. This image is a first test incorporating video (from Aeon Flux).
The show [...]
PatchBox in action
Tidying up the features I’ve been adding and making sure the scripting interface is solid.
This whole scene is now triggered by two scripts: one to create the skybox and the other to load the city replete with ‘punk’ style shaders and building textures.
Need to formalise the colour scheme and link the buildings with [...]
Shaders, and a world sphere, and the Chrysler Building
The city scape I’m working on is progressing.
After reading up some more on OpenGL 3.0, and noting the depreciation trend, I decided to make some fairly heavy duty changes to the PatchBox engine - namely make as much of the rendering take place using shaders.
Every bit [...]
Am working on a new PatchBox patch for an event Quadratura is doing on November 1st. It involves a moving city scape, which I originally intended to be revolving from right to left with various levels of parallax.
I already have most of the script code needed for this so thought I’d try something a little [...]
Technorati Tags: PatchBox
Lots of work done on PatchBox over the past couple of weeks, and I was finally able to test it out with a TripleHead2Go, which worked seamlessly outputting to three projectors at 1024×768 at 50 FPS.
Re-wrote the task scheduler to be more extensible. This has enabled a ‘job’ to be wrapped in a (sub)classed object [...]
