OGRE 1.7.1 [Cthugha] Released!

We’re happy to announce the first maintenance release to the new 1.7 stable branch (codenamed ‘Cthugha’), delivering as per usual a plethora of bug fixes which you can find a list of after the jump. As you would expect there are no feature changes or API breakage in this release – we save those for the unstable development branch – which of course you can grab from Mercurial if you want to join us on the bleeding edge.

So far the source releases and some of the SDKs are ready for download for 1.7.1, if your SDK isn’t updated yet, please be patient as these will come online soon. Or alternatively, try using the source release, it’s really not that scary :)

[edit] cg.dll was missing from the early version of the SDKs for Windows, we’re fixing this now, check for updates after 2 May 2010.

Changes since 1.7.0:

  • Terrain: Fix memory leak after updating lightmaps
  • Terrain: Ensure that imported position is used when preparing from ImportData
  • Fix calcMorphKeyframeSize in serializer – there has never been an ‘isOriginalGeometry’ flag!
  • Safety checks – use !mSkeleton.isNull() instead of hasSkeleton() when accessing the pointer, since hasSkeleton() determines whether the skeleton name is provided, not whether the skeleton has loaded & the pointer is valid
  • Terrain: Fix a delete that should have been OGRE_DELETE as pointed out by harkon
  • Focussed shadow camera setup dealt with extrusion of directional light volume incorrectly: – It clipped the extrusions against the scene AABB, which may exclude casters in sparse scenes where the main camera has stopped seeing them or their shadows for a frame or more – It should actually have been extruding the receivers AABB clipped to the camera by the shadow far distance – Focus regions would not be affected because extrusion along the light direction does not widen the focus; in fact the use of the whole scene BB instead of just the receivers BB may have led to worse focus
  • ArchiveManager’s constructor should be in source, not header, to avoid link errors if constructed from outside OgreMain (this fixes tests build on OS X) Fix some new/deletes in tests that should have been OGRE_NEW/OGRE_DELETE
  • Mark a few more options as ‘Advanced’ to de-clutter the main CMake page. Disabling zip, freeimage, dds etc is definitely an advanced function.
  • Patch 2981322 – allow OGRE_LIB_DIRECTORY to be set to install in alternate named directories such as lib64 for 64-bit Linuxes that use that convention.
  • Fix for VC10
  • Patch 2986452: avoid potential resource group change deadlocks
  • Patch 2986446: For ACT_LIGHT_POSITION_OBJECT_SPACE for directional lights, we need to use the inverse of the inverse transpose as with ACT_LIGHT_DIRECTION_OBJECT_SPACE, to deal with non-uniform scalings
  • Patch 2986441: MovableObject’s queryLights and _notifyCurrentCamera didn’t take account of object scaling when dealing with bounding radius
  • Patch 2986437: auto-tracking update should be after the re-entrant call to update shadow textures, otherwise old tracking state may be used
  • Fixed BillboardChain::getNumChainElements when tail < head
  • Fix loading of mesh versions 1.30 and before They were picking up LOD loading from latest version instead of fallback in MeshSerializerImpl_v1_4 because of inheritence error
  • In Mesh::destroySubMesh, fix up SubMesh name map for the removed item
  • If group name on manual LOD level is blank, use parent mesh
  • Make PlayPen plugin work on OS X
  • Fix bug 308 according to user report – don’t include _mingw.h in more recent MinGW packages
  • Fix bug 313: doc build target doesn’t handle spaces in directry names
  • Fix terrain rendering on ATI/GL – no support for fp30/fp40 in latest ATI drivers but arbfp1 works
  • Terrain morphing was missing from shader when alignment wasn’t x/z
  • Deal with CMAKE_OSX_ARCHITECTURES a little better: – Selectively remove 64-bit archs (Carbon requirement) instead of manually setting “i386 ppc”, so that user can still customise archs for 10.6 – Set the default arch if none is specified (Cmake 2.8.0)
  • Patch 2977286: Fix support for scene blending operations other than SBO_ADD on Dx9 because caps were not being set
  • Patch 2979431: Matrix4::makeInverseTransform bug with non-uniform scale
  • Patch 2978035: D3D9 should send a “DeviceLost” message to app-side listeners before a device is reset
  • Deferred Shading Demo : Fixed ‘is camera inside light’ test for spotlights.
  • Fix problem with picking the right shader generator in TerrainMaterialGeneratorA – Would not fall back from Cg when Cg not available (bad nesting) – Can only use ps_2_0 when not parallax mapping
  • Fix memory leak in SharedPtr when initialised with a null pointer
  • Ensure libdl exists before linking to it
  • Fix install of tools PDBs in debug mode
  • Add test for switching full screen modes without reinitialisation
  • (Fixed commit) Applied l3fthn4d’s compositor (material_scheme & shadows settings) patch as discussed in http://www.ogre3d.org/forums/viewtopic.php?f=4&t=56031
  • Fix bug 305: Entity::setMaterialName(material, group) calls SubEntity::setMaterialName(material) without group.
  • Add the rtshader materials directory to resources.cfg
  • Correct case-sensitivity issue with samples media path
  • Remove nested parenthesis, not supported on CMake 2.6 (only 2.8)
  • Explicitly include errno.h. Otherwise build errors occur if not using boost and threading is turned off.
  • Patch 2971821: Fix consistency of inclusions of OctreeSceneManager plugin (important when referenced with relative paths)
  • Patch 2971818: deal with missing MinGW header & make inclusion specific to MinGW
  • Just make sure meshes are being reloaded in LOD test
  • Added tests for manual LOD, seems to work
  • Explicitly note in the manual some directives which are irrelevant when using shaders
  • Another bad svn:eol-style property
  • Fix some bad svn:eol-style properties
  • More Xcode template work. Cleaned up warnings. Changed iPhone template to use a NSTimer to make it more reliable at high framerates. Fixed the installer path.

  • Patch 2963406: Deal with negative scale in Entity::getBoundingRadius
  • Patch 2963372: Matrix4::makeTransform/makeInverseTransform inefficiencies fixed Reduces complexity of this from 39MUL+30ADD to 18MUL+15ADD
  • Must set the OGRE_MEDIA_DIR_* to an absolute path for build folder versions
  • Patch 2959565: fix XSI exporter build

  • Changes for building SDK for iPhone
  • Should delete .exe not .7z when building SDK multiple times
  • D3D9 Render System: Device multi thread flag is used now only when OGRE_THREAD_SUPPORT == 1. This will save us a few cycles in the other threading modes..
  • FindOIS.cmake fixes: – Respect OGRE_DEPENDENCIES_DIR (useful if used outside of OGRE) – On Win32 define names of the OIS DLLs so they can be copied from wherever they are found
  • FindOGRE.cmake fixes: – Use OGRE_DEPENDENCIES_DIR if defined (external dependencies) – Find media in the OGRE_SOURCE folder correctly – Use a zip file common to 1.6 and 1.7 to detect media (OgreCore.zip doesn’t exist anymore in 1.7+)
  • Compile fix for people using ExampleFrameListener
  • RTSS: Fixed Normal map point and spotlight GPU parameters that weren’t update correctly.

  • Fixes and enhancements for MinGW SDK generation.
  • Merged v9841 into tag since urgent change
  • Merged v9841 into tag since urgent change
  • In future, use the Windows-mode 7zip self-extractor not the default console-mode one
  • Final changes for the OS X SDK. Fixes up all the absolute paths in CMake generated files.
  • OGRE_VERSION has a whitespace and version suffix appended; this breaks builds if used as the .so version for shared libraries. Use a dedicated OGRE_SOVERSION instead.
  • RTSS: Fixed Normal map and PSSM3 GPU parameters that weren’t update on object switch scenario.
