99313d225b From Roger James, The changes are as follows:- 
1. Support for ambient occlusion maps.
2. A fix for the incorrect handling of normals on all geometries. The optimizer usually fixed this bug so it probably was not noticed very often.
3. A new option flag on the reader. "StrictTransparency"
          // Process transparent and transparency settings according to a strict interpretation of the spec
          // See https://collada.org/public_forum/viewtopic.php?f=12&t=1210
otherwise
          // Jump through various hoops to accomodate the multiplicity of different ways
          // that various people have interpreted the specification
4. Handling of texures in the transparent channel. This is allowed provided that they are the same texture that is specified in the diffuse channel. Accomodating a different texture would require use of programmable pipeline functionality which I have tried to avoid.
5. Handling of <bind_vertex_input> elements.

908432c732 Replaced readImageFile() usage with readRefImageFile() to prevent threading issues with caching of imagery in the osgDB::Registry cache. 2009-01-21 18:23:55 +00:00

e17535813f From Jason Beverage, "I realized today that there is an issue with the Registry changes I submitted to allow plugins to have the first go at URLs. 
The code works fine as is if the format plugin is not already loaded in memory.

If a plugin is already in memory, say the PNG plugin for example, then a call to readImageFile("http://server.com/image.png") will return FILE_NOT_FOUND because osgDB::findDataFile will not be able to locate the file.  So the Registry::read method is returning before the CURL plugin is given a chance to download the file.

I've made a few changes to the Registry to not return FILE_NOT_FOUND if the filename contains a URL that fix the issue."

2f7fb53ff7 From Rudolf Wiedemann, "attached is the osg::Camera class (based on revision 9493), where 
methods
 getProjectionMatrixAsOrtho()
 getProjectionMatrixAsFrustum()
 getProjectionMatrixAsPerspective()
 getViewMatrixAsLookAt() (2x)
are now const, as they only call const methods of osg::Matrixf/d.
