Reality Augmenter Release Notes 1.1.0

Another update that’s been a long time coming. The main focus of this update is the underlying OpenGL code, which has been upgraded to support Core Profile 3.2. This was done for a variety of reasons. To enable better code sharing with a future iOS app, to better support new features to come soon and generally bring the code up to modern OpenGL Standards. The Fixed Function Pipeline is gone, drawing has been simplified and shaders upgraded.

In addition I’ve also fixed the annoying hang or crash that could occur mainly when adding or removing chop areas. A little more GPU memory is consumed when using views with previews, the output view has no such views and should be used for when optimal performance is required. Drawing to GUI views is now only done in the main thread, the background rendering no longer tries to lock views and should be more performant, this means a bit more latency on the previews, but the full screen projection areas still render at the maximum refresh rate with as little latency as possible.

OpenGL Changes

  • Updated all OpenGL code to support Core Profile 3.2.
  • Previews render in the main thread and made thread safe.
  • Quartz Composer is still supported via a seperate Legacy Context.

Other

  • Fixed crash or hang when adding or removing chop areas.
  • Removed rendering start delay on opening a new file.
  • General code clean and removal of outdated code.

Custom QC Processor for Rane Sixty Two

Spent the afternoon building a custom QC overlay for the Rane Sixty Two that can be used as a processor in the Reality Augmenter.  Ideal resolution is 370×720 px for the processor. (Based on the dimensions of the mixer, 265mmx360mm, I just double the values for a nice crisp finish)

It takes image inputs for the Preview area and loops, and let’s you quickly setup a layer covering the entire Sixty Two in one go, reducing setup time.

It also enhances the EQ knobs, giving a nice readout on their levels.

Quick vid showing it in action:

EDIT : I updated the QC File to use a macro instead of a custom library patch, wasn’t sure if custom library patches are exported with compositions.  Anyway, this one should be completely self contained.  No plugins required.

Reality Augmenter Release Notes 1.0.4

It’s been a while since the last update, to be honest, I took a bit of a break over Christmas and new year after working non stop for so long! Been getting back on the horse again, new updates and developments to start coming again.

New Features

  • Can now add Quartz Compositions as sources as well as processors.
  • Saved files now use the extension .rag instead of .binary, files using the old extension will still load.

OpenGL Optimisations

  • Better context management means fewer context switches and locks.
  • Reduced openGL flushing.

Other

  • Reduced use of OSX Cocoa specific code to enable a future iOS release with shared code base.
  • Code restructure as part of the above.
  • General code clean and removal of outdated code.
