a793958836 From Johannes Baeuerele, "I have extended the pvr reader plugin to support etc1 compression(GL_ETC1_RGB8_OES). The changes attached to this submission are based on today's trunk.
The pvr format which can be used as a wrapper for different compressed and uncompressed formats supports this compression algorithm. The original pvr compression uses the pvrtc format. The handling of pvrtc is already implemented in the pvr plugin. PVR provides wrapper functionality for some formats, e.g. etc or even dxt/dds.

Our target system (gles2) is able to use the etc compression format. With minor changes in the submitted files, there is no need to write a separate plugin. However the original pvr texture compression formats are not supported on our target, which is the reason for this extension.

The changes mainly consist in the definition on new enum values in the classes and headers of ReaderWriterPVR,Image and Texture. I also found some locations where the handling of the original pvr textures was not implemented. These are also part of this submission."

65aee287e7 From Mathias Froehlich, "Attached are most of the fixes that are required to build osg on solaris and
hpux. I have skipped irix this time as irix is too dead to keep osg building
there.

As usual, solaris does not like member templates in stl containers.
Some headers missing and link problems due to missing libraries."

1c6e33bc7e From Wang Rui, "Attached is a fix to the latest PVR plugin to make it compile under
MSVC. I've added definition to uint_32 and replaced std::max() with
osg::maximum(), because it is not supported by some VisualStudio
versions."

d2a9f48054 From Per Fahlberg, "I have added support for PowerVR texture compression. osg::Texture and osg::Image have been modified to support the texture formats and I have added a plugin to load pvr files. All modified files are in the attached zip. " 2010-11-04 11:02:37 +00:00
