  • G3D::ImageFormat::BGRA8 [Mike]
  • Added convertRGBA8toBGRA8 functionality to PixelTransferBuffer::convertBuffer() [Mike]
  • Modified Win32Window::setIcon to properly convert the icon to BRGA. (Our G3D icon now displays properly). [Mike]
  • Added enum ImageFormat::NumberFormat which is {FLOATING_POINT_FORMAT, INTEGER_FORMAT, NORMALIZED_FIXED_POINT_FORMAT, OTHER}. To eventually replace the floatingPoint boolean. Modified the constructor to match, and set its value for all image formats specified in the .cpp. [Mike]
  • ImageFormat::isIntegerFormat [Mike]
  • ImageFormat::channelMask, which returns a Color4 that masks off unused components in the format, given in RGBA. For example, the mask for R32F is (1,0,0,0), for A32F is (0,0,0,1), for RGB32F is (1,1,1,0). (Note that luminance is interpreted as using only the R channel). Used by GLCaps::supportsTextureDrawBuffer(). [Mike]
  • GLCaps::supportsTextureDrawBuffer(const ImageFormat* fmt). Extended RenderDevice::init to write out the result of this function for each format alongside the supportsTexture and supportsRenderBuffer functions. [Mike] <
    • >
    • Modified MD3Model::findFrameNum() to make the animations smoother until we get to implementing blending between animations [Mike]
    • Added an optional mipLevel parameter to getTexImage, which defaults to 0. [Mike]
    • Implemented G3D::Texture::generateMipMaps() (It was defined in the header but not implemented before). [Mike]
    • Modified G3D::Tri::Intersector to store a backside boolean if we hit the backside of the Tri. getResult will flip normals/tangents if this is true. [Mike]
    • Added a new twoSided parameter to the Tri constructor, if set to true, Tri::Intersector will do double-sided intersections. (used sign bit of area, no change to Tri size) [Mike]
    • Removed G3D::Tri::otherSide() (it does not work with the new CPUVertexArrayFormat). [Mike]
    • Removed the CPUVertexArray* from Tri. Updated all methods that access information about Tri to take a const Ref to a CPUVertexArray, and added G3D::TriTree::getCPUVertexArray() (Tri is now 24 bytes in a 64 bit build) [Mike]
    • Removed v0, e1, e2, from G3D::Tri. Added the methods e1 and e2. Changed Tri::m_doubleArea to Tri::m_area for intuition's sake (Tri is now 32 bytes in a 64 bit build)[Mike]
    • Completely redesigned G3D::Tri. It now stores only v0, e1, e2, three indices into a G3D::CPUVertexArray, a pointer to G3D::CPUVertexArray, a lazy_ptr<UniversalMaterial>, and doubleArea (72 bytes in a 64 bit build). [Mike]
    • Now Passing a pointer to the G3D::TriTree throughout all intersectRay functions, and uses it to set G3D::Tri::Intersector's primitive index [Mike]
    • Added G3D::Surface::getTris(), a static method which takes an array of surfaces and returns a G3D::CPUVertexArray and an Array<Tri> from the surfaces, by separating the surfaces by subclass and calling getTrisHomogenous() on them. [Mike]
    • Added G3D::Surface::getTrisHomogenous(), a virtual function that, when implemented in subclasses, will take an array of surfaces and append to the G3D::CPUVertexArray and the Array<Tri> appropriately. [Mike]
    • Added G3D::UniversalSurface::getTrisHomogenous(), which is a UniversalSurface-specific implementation of G3D::Surface::getTrisHomogenous() [Mike]
    • Added G3D::CPUVertexArray::Vertex::transformBy() that takes a G3D::CoordinateFrame and transforms its position, tangent, and normals by the CFrame (object to world). [Mike]
    • Added G3D::CPUVertexArray::transformAndAppend() which takes a G3D::CPUVertexArray and a G3D::CoordinateFrame and appends the parameter array, transforming tangents, normals and positions from object to world space. [Mike]
    • Removed G3D::Tri::getTris(). Use G3D::Surface::getTris() instead. (updated everything internal to G3D to reflect this change) [Mike]
    • Renamed G3D::Tri::vertex() to G3D::Tri::position(), and added a new G3D::Tri::vertex() that returns the G3D::CPUVertexArray::Vertex for the specified vertex. [Mike]
    • Added G3D::Array::copyPOD() and G3D::Array::appendPOD() for fast array copy and append for "Plain Old Data" [Mike]
    • Added G3D::Array::copyFrom() to wrap up the idiom of resize(0) append(array) [Mike]
    • Disabled operator=() for G3D::CPUVertexArray [Mike]
    • Added a copy constructor for G3D::CPUVertexArray, and added G3D::CPUVertexArray::copyFrom() [Mike]
    • Added a primitive index variable to intersector, and use it to set G3D::SurfaceElement::SourcePrimitive index [Mike]
    • Modified G3D::SurfaceElement to contain a SourcePrimitive struct containing u, v, and, if set explicitly, the primitive's index [Mike]
    • G3D::Tri::Intersector::operator() now correctly uses the twoSided boolean. We had to rewrite the code and we took a 3% performance hit for ease of maintenance. [Mike]
    • Changed the NO_FFMPEG macro to G3D_NO_FFMPEG and changed it to be defined in platform.h instead of in VideoOutput.h [Mike]
    • G3D::Tri and G3D::Tri::Intersector no longer virtual, this decreases Tri size by 8 bytes in 64-bit builds [Mike]
    • Removed n the facenormal from G3D::Tri and replaced with doubleArea (e1.cross(e2).length()) [Mike]
    • G3D::RenderDevice::applyRect
    • G3D::lazy_ptr
    • VertexRange renamed to AttributeArray
    • G3D::GuiTextureBox now saves out cubemaps at 4x the width and 2x the height of one of its faces, in the panoramic view [Mike]
    • Renamed VertexAndPixelShader to ShaderProgram, matching OpenGL terminology (this was deprecated anyway)
    • canBeIndexType renamed to glCanBeIndexType
    • glIsNormalizedFixedPoint
    • G3D::Vector2unorm16
    • Added Show Cube Edges option to G3D::GuiTextureBoxInspector [Mike]
    • Reduced RenderDevice::MAX_TRACKED_TEXTURE_IMAGE_UNITS, RenderDevice::MAX_TRACKED_TEXTURE_UNITS, and RenderDevice::MAX_LIGHTS to 2 as we remove fixed-function to speed up programmable shading.
    • Added focus controls to G3D::CameraControlWindow
    • G3D::ArticulatedModel::CleanGeometrySettings::allowVertexMerging
    • G3D::Matrix4::upper2x2
    • G3D::Texture::isCubeMap
    • G3D::GuiTextureBoxInspector displays the x,y,z vector used to access the texel the mouse hovers over, instead of u,v coordinates. The texel value display is broken for cubemaps, however. [Mike]
    • G3D::GuiTextureBox supports rendering cubemaps as a panoramic texture (of double a single face's width), using u,v coordinates as scaled spherical coordinates. [Mike]
    • G3D::Texture now checks for if it is a cubemap on construction and sets visualization.isCubemap appropriately. [Mike]
    • G3D::Texture::Visualization: Added isCubemap boolean. Modified the constructors, ==, needsShader() and toAny to reflect this change. [Mike]
    • G3D::Rect2D::operator*(const Vector2& s) [Mike]
    • G3D::Texture::update(), G3D::Texture::getTexImage(), and G3DTexture::getImage() all have a new parameter that specifies the face of the cubemap to use. [Mike]

Primary development team: Morgan McGuire, Corey Taylor, Shawn Yarbrough, Trevor O'Brien

Changes in 8.00:

8.00 changes incompatible with G3D 7.xx and earlier:

  • Linux/FreeBSD build now depends on libzip and is not built internally. OSX/Windows version of zip.lib was replaced with libzip. The original implementation was based on minizip.
  • G3D::GuiTheme changed to use .gtm theme files. Specification updated to version 1.0
  • G3D::OSWindow::Settings::fsaaSamples -> G3D::OSWindow::Settings::msaaSamples
  • G3D::Texture::Preprocess::brighten -> G3D::Texture::Preprocess::modulate
  • Surface::renderTransmissives -> G3D::Surface::renderTransmissives
  • G3D::UserInput has joysticks disabled internally to avoid confusion for new users
  • Surface::hasTransparency -> Surface::hasTransmission + Surface::hasPartialCoverage, to support varying partial coverage modes
  • UniversalBSDF::packSpecularExponent now uses a nonlinear scale between 0 and 1025

  • Removed G3D::Texture::invertY (See G3D::RenderDevice::invertY)
  • G3D::Matrix4::perspectiveProjection flips the y-axis by default (see upDirection argument to get the old behavior)

  • G3D::TextInput now treats \r, \n and \r\n as newlines with or without newline tokens. Each increment line number once and reset character number
  • G3D::TextInput now generates tokens for both line and block comments when enabled. This changes the G3D::TextInput::Settings flags.
