NVIDIA GameWorks OpenGL Samples Release Notes

New Sample: NVPR Cursive Text Sample shows how to use NV_path_rendering to animate the dash pattern of a stroked path, as a way to simulate live cursive writing.
New Sample: NVPR Shaped Text Sample shows sophisticated text layout using the open source HarfBuzz text shaping engine library to position glyphs for strings of Unicode text.
New Sample: NVPR Text Wheel Sample shows using the NV_path_rendering OpenGL extension to draw text arranged like spokes in a wheel, with a slight 3D projection applied to the rendering.
New Sample: NVPR Tiger 3D Sample shows how NV_path_rendering content and conventional 3D graphics can be mixed in the same 3D scene.
New Sample: NVPR Tiger Warp Sample shows how to draw the so-called 'PostScript Tiger' artwork, consisting of 240 paths specified as cubic Bezier curves and line segments.
Replaced Sample:NVPR Basic Path Rendering Sample replaces Path Rendering Sample.

Release 2.0 is a Major release, focusing on GeForce Maxwell-level GPU features.

Layout Change: The samples are now grouped by common feature set. Currently, this means that the samples are grouped by GPU level and API.
New Sample: BlendedAA shows how to use Target-independent Rendering (TIR) to lower the memory requirements for antialising.
New Sample: Cascaded Shadow Mapping shows how to use Viewport Multicasting and Fast Geometry Shaders to optimize the performance of Cascaded Shadow Mapping.
New Sample: Conservative Rasterization Sample demonstrates the basics of hardware-based Conservative Rasterization, a method of ensuring that every pixel touched by geometry is shaded, independent of sample coverage.
New Sample: Normal Blended Decal Sample demonstrates the use of Pixel Shader Interlock (PSI) to implement fast, safe custom blending.
New Sample: Weighted Blended OIT Sample demonstrates fast Order-Independent Transparency (OIT) via the methods based on a modified blending equation.
New API: The app framework now supports three redraw modes: Unbounded (the previous method), VSYNC (apps are given draw calls on each VSYNC or compositor redraw; optional) and on-demand (only when the app requests).
New API: Wrappers are now provided to make it easier for apps to compile against OpenGL ES 3.1 AEP.
New API: Applications can now request MSAA support in their configuration callback.
Bug Fix: OpenGL extension-string checking is now more robust.

Release 1.2 is a feature release with no known "breaking" changes.

New Platform: Linux for Tegra (a full Ubuntu desktop on Tegra platforms) support has been added for all samples. The samples now run on NVIDIA Jetson TK1.
New Sample: ComputeParticles shows how to use Compute Shaders and buffer interop to use the GPU to animate and render particles without CPU involvement.
New Sample: ComputeWaterSurface shows how to use Compute Shaders to generate a dynamic water surface with ripples and reflections.
New Sample: FXAA demonstrates a simple, high-performance and easy-to-integrate antialiasing method as a 2D post-process.
New Sample: HDR demonstrates tonemapping, cinematic flares and refraction.
New Sample: MultiDrawIndirect demonstrates OpenGL performance features known as Approaching Zero Driver Overhead ("AZDO").
New Sample: OptimizationApp demonstrates CPU and GPU timers for app-level profiling as well as switchable, basic optimization techniques.
New Sample: SoftShadows demonstrates multiple projected texture methods, including multi-sampled penumbrae.
New API: The app framework now includes a function to query whether a GL context is bound, NvPlatformContext::isContextBound().
Known Issue: The pre-compiled Android version of ComputeWaterSimulation has an incorrectly-named icon (reads "ComputeParticles"). The sample works, and rebuilding it will fix the icon name.

Release 1.01 is (as its version implies) a bugfix release with no known "breaking" changes.

OpenGL ES3.1 contexts are now supported. There is also a default ES3.1 context version object: NvGfxAPIVersionES3_1.
Some bugs in the EGL setup code and the image-loading code that caused ES3.1 contexts not to work are now fixed. All samples that can support ES2 or ES3 now work if the app requests ES3.1 as well.
The min-API and missing extension error dialogs now include more descriptive strings to explain to the user what was found and what is needed.
The image loader now auto-expands DXT textures to RGBA on systems without DXT support.
The UI system now handles window resize correctly on platforms with windowed mode.
Android's NDK r9d is now the default NDK version when building Android apps from Linux host.
NvGLSLProgram::bindTexture2D was not setting the texture on the correct (passed in) texture unit. This has been fixed.
Log-based framerate printing has been disabled by default, since it is printed to the screen.
A typo in the default window size on Win32 has been fixed (window size is now 1280 pixels wide instead of 1270).
The period (.) key is now mapped on Linux and Win32 platforms.

Release 1.0 is the first version of the new samples pack.
