GL Tools

Changes since 1.5

• Fixed issue with GL Stereo Environment flickering on Mac OS X 10.6.
• Added new GL Structure Renderer patch --- renders its subpatches multiple times, once for each element in the provided structure, after applying the specified transformation.
• Source code is available on GitHub.

Thanks to @toneburst, @gtoledo3, and @cybero for help sorting this out.

Known issues

• The GL Field of View patch doesn't work properly on Mac OS 10.9 (it produces stretched output).

Changes since GLTools 1.4

• New Stereo Environment patch, which renders its child patches twice using an asymmetric projection frustum, once for the right eye, once for the left eye, and provides each as an image output.
• New Look At patch (a two-point camera).
• New Camera patch (a one-point camera).
• Added "Image Structure" input to the GL Quad Structure patch.
• Fixed GL Inverse Rotation so that it executes every frame (rather than only once).
• Fixed SuperGLSLGrid so that color uniform values are properly set in 64bit mode.
• Separated the Alpha blendmode override to a separate plugin, so that GLTools itself doesn't perform any runtime hackery (and is thus somewhat less risky).

Changes since GLTools 1.3

New Features

• GL Frustum Patch (perspective equivalent of the GL Ortho Patch)

Updates

• Added support for Snow Leopard's new structure representations (allowing use with the OpenCL and Mesh Components patches)
• Fixed issue with GL Spline crashing while making changes on a non-rendering composition.

This build of GLTools fixes numerous bugs with Snow Leopard compatibility, and some PPC bugs on Leopard as well. Some minor performance improvements were made, as well as other minor bug fixes.

Some new private patches were added/modified -- they're still private, so please don't expect them to remain compatible/unchanged in the future.

Please be as clear as possible with bug reports (include sample compositions, descriptions, steps to reproduce, etc.) -- we're rather backlogged at the moment, so saving us a few minutes here and there helps a lot.

This build of GLTools includes much more debugging information to help us track down a few reported issues (mostly with the spline patch). It also contains some cleanup/optimizations.
