CPU usage reduced when wind conditions change
Added fft-lod-bias config setting to combat aliasing / motion artifacts

Version 1.37 April 15, 2012

Version 1.36 April 4, 2012

Put grid resolution back at 512

Version 1.35 March 30, 2012
Optimize performance when wind conditions change
Align projected grid with the horizon line
Reduce projected grid default dimensions (thanks to the above change) - gains performance
WakeGenerator::Update now takes an explicit direction vector. Trying to guess at it automatically wasn't sufficient.

Version 1.34 February 10, 2012
Added visualCorrelation parameter to Ocean::GetHeight() to match heights with visuals in the distance
Ensure WakeGenerator::Update() doesn't actually do any drawing, as it could be called from a different thread 
or context from Ocean::Draw().
Better conservation of wake waves (to reduce anomalies from hitting the max number of wake waves in the shaders)

Version 1.33 February 5, 2012
Fix above/below water test
Fix dark line at horizon in geocentric mode near surface
Fix clipping of ocean when near surface in geocentric mode
Fix undefined foam values in Gerstner mode
Fix precision issues in DirectX geocentric mode

Version 1.32 February 2, 2012
Fix wakes in OSG reflection demo when --geocentric is on
Improve foam appearance
Fix various precision issues in OpenGL geocentric mode

Version 1.31 January 31, 2012
Tuned grid resolution and maximum wake height
Added wake-kelvin-wakes config setting to disable 3D ship Kelvin wakes independently from turbulent wakes (see wake-propeller-backwash)
Decreased default setting for max wake waves

Version 1.3 January 30, 2012
Ship wake improvements: added propeller wash effects, separate spray and wake generation points,
and ability to simualte the beam width and ship length. See new WakeGenerator constructor for more details.
Enabled flow control in HLSL - big speedups for DX9 and DX11!
Split up projected grid into 32K chunks under DirectX9 to support low end systems
Improve accuracy of height queries (takes choppiness into account now.)
Fix potential buffer overflow in OpenGL particle systems
Max number of wake waves visible at once now configurable by renderer, and increased for DX11 and OpenGL
Fix orientation of projected grid when camera is inverted
Updated to CUDA Toolkit 4.1, AMD APP SDK 2.6, and AMD APPML 1.6
Fix OpenSceneGraph samples so they run with arbitrary working directories and do not require fftss.lib in Windows
Fix precision issues in geocentric mode when close to the surface
Fix translation of the ocean surface in geocentric mode
Fix default ocean slope if unspecified in geocentric mode

Version 1.23 January 9, 2012
Fail if DX9 vertex shader model 2.0 is all that's supported. Vertex shader model 3.0 or newer is required.
Support combination of DX9 PS 2.0 / VS 3.0 for older hardware
Fix jitter on spray particles in geocentric coordinate systems
Fix spray and wave orientation if Ocean::SetDepth is not called

Version 1.22 January 4, 2012
Enable shallow water translucency for DX9 and DX11
Direct3D9Ex support added
CMake works under Windows now, with option to not include DirectX when building.
Fix fallback case to IPP if FFT setup fails

Version 1.21 December 18, 2011
Added Ocean::SetRefractionColor to allow changing of the ocean color at runtime
Fix warnings from Allocator
Added Gamebryo Lightspeed 3.2 sample code
Fix crash if OpenGL renderer is specified with a DirectX environment
Added Visual Studio 2005 support (except for DirectX11)

Version 1.2 November 12, 2011
Breaking waves and spray effects - toggle with Ocean::EnableSpray()
Ocean::SetDepth now takes a surface normal as well as a depth at the camera position, allowing
for sloping shorelines
Water is transparent when refracted in shallow water. The underwater visibility simulated, and
the values passed into Ocean::SetDepth, will influence this effect. Try the "beach" button in
our demo to see it in action.
Fix surface normal calculation in intersection tests
Fix intersection tests when coordinates are negative
Fix intersection tests in OpenCL
Make waves change smoothly when wind conditions change
Fix SimulateSeaState when using non-standard world units
Improved the fit of the projected grid with the visible scene, increasing resolution.

Version 1.14 October 27, 2011
Beta Linux support introduced - contact support@sundog-soft.com
Fix artifacts when rolling the camera
Explicitly declare calling conventions and byte alignment for better project compatibility
No longer uses ARB extensions; uses OpenGL 2.0 functions directly.
Fix directional light in DX11
Fix crash when using a ResourceLoader with an invalid path
Fix scaling of projected grid when corners project to infinity
Full source project fixes: uses DXSDK_DIR to locate the DirectX SDK; renames debug library build to Tritond.lib

Version 1.13 October 15, 2011
Removes dependency on GLEW entirely.
Fix build settings for x64

Version 1.12 October 12, 2011

Negative reflection vectors now handled better
Fixed CUDA with Direct3D11
Fixed computation of grid size with non-zero sea levels

Make shaders compilable with latest Intel GPU drivers
Fix x64 support
Pre-allocate temporary FFT buffer for OpenCL
Updated to AMD APP SDK 2.5 and clAmdFFT 1.4.135

Version 1.0 (revision 274) August 3, 2011
