  • FIX: warning: passing `double' for argument 1 of `void G3D::Queue<T>::repackAndRealloc(int)'
  • Optimized static Matrix3::transpose (36 cycle) and Matrix3::mul (52 cycle) variations.
  • Changed some lerp arguments from float to double
  • MeshAlg::computeTangentSpaceBasis
  • Draw::axes now uses scale to compute axis length
  • New ParallaxBump demo
  • Changed several Vector3 return values from float to double
  • Real-world stars, sun, and moon path (Nick Musurca)
  • Now compiles under MSVC++ 7.0 (David Baszucki)
  • Now compiles under g++ OS/X (Ben Landon)
  • Changed the default RenderDeviceSettings::alphaBits to 0 in the hope that it will work with more graphics cards.
  • Matrix3::fromX methods became factory methods
  • G3D::sinc
  • Multi-platform lib directories
  • Vector3::average(), Color3::average(), Vector3::sum(), Color3::sum()
  • Ray::reflect, Ray::refract
  • Physically correct sky model
  • FIX: Older graphics cards can now initialize properly
  • Increased fuzzyEpsilon to 0.000001
  • Color3::max, Color3::min, Color4::max, Color4::min
  • Array::sortSubArray
  • GCamera::getClipPlanes now takes a G3D::Array
  • G3D::AABox
  • Box::randomInteriorPoint, Box::randomSurfacePoint
  • Vector3::cosRandom, Vector3::hemiRandom, Vector3::reflectAbout, Vector3::reflectionDirection, Vector3::refractionDirection
  • log(Color3)
  • Upgraded to zlib 1.2.1
  • VAR::valid (Peter)
  • System::getLocalTime, System::getTicks
  • High-performance cycle count and time queries on Linux
  • UserInput::anyKeyPressed
  • G3D::Box now provides axes, center, and extent information (serialization is backwards compatible to 5.xx)
  • TextInput's exceptions now provide file, line, and character numbers as well as preformatted error messages in the style of MSVC++.
  • G3D::Texture::fromGImage
  • G3D::TextInput now parses hex numbers of the form 0x#####
  • G3D::CollisionDetection::penetrationDepthForFixedSphereFixedPlane
  • G3D::CollisionDetection::penetrationDepthForFixedSphereFixedBox
  • G3D::beginMarkShadows, G3D::endMarkShadows, G3D::markShadows

  • Two-sided stencil operations
  • Removed G3D::Real
  • FIX: [ 855947 ] Fonts are broken on Radeon
  • Switched vertex arrays to use the new ARB_vertex_buffer_object extension. Compared to 5.xx rendering speed: NVIDIA/Win32 is the same (fast), ATI and Linux rendering are about 10x faster. The API has changed slightly-- most significant, the vertex, normal, color, etc. arrays must all come from the same VARArea now.
  • Disabled the "conditional is constant" level 4 warning on Windows that is triggered by the for-loop scoping fix.
  • G3D::SkyParameters::directionalLight
  • G3D::TextureManager (Peter S. & Morgan)

  • Renamed CImage to GImage
  • G3D::Matrix3::getRow
  • Added optional argument drawCelestialBodies to Sky::create.
  • RenderDevice::getTextureMatrix
  • Depth Textures
  • Texture::createEmpty
  • RenderDevice::setViewport has flipped the y-axis since version 5.00
  • ReferenceCountedPointer::isLastReference
  • Support for textures beyond the number of texture units (which occurs on NVIDIA cards)
  • G3D::PosedModel
  • G3D::IFSModel
  • G3D::CoordinateFrame::normalToObjectSpace, G3D::CoordinateFrame::normalToWorldSpace
  • Simplified arguments on Texture::copyFromScreen
  • Moved Camera in GLG3D to GCamera in G3D
  • Moved setProjectionAndCameraMatrix from Camera to RenderDevice
  • Moved G3D::Rect2D to G3D from GLG3D, changed interface
  • G3D::setRenderMode
  • G3D::RenderDevice::setSpecularCoefficient, G3D::RenderDevice::setShininess
  • G3D::GLight

  • RenderDevice::project
  • RenderDevice::push2D() now uses the current viewport instead of full screen by default
  • RenderDevice::getViewport
