0.5 (2017-03-16)¶
New Features¶
Added function to get effect properties from underneath the technique tag.
Add example how to visualize DAE file using OpenGL API.
Bug Fixes¶
Fix Python 3 image loading.
Fix missing import.
changed itervalues() to values() for compatibility with python3.
Change iteritems() to items() in getInputList. Add test. Fixes #40.
Fixing conversion from unsupported texcoord. input.
use ‘from PIL import Image’ instead of ‘import Image’.
Fix case where getitem is called before normal indices are set up.
Fixed shader compilation error. Old GLSL compilers do not like precision statement.
Apply patch to fix ctypes-usage issue.
Convert some Windows-style files to Unix format (linebreaks).
Fix the bug with relative path to default dae file.
0.4 (2012-07-31)¶
Backwards Compatibility Notes¶
Python 2.5 is no longer supported. Supported versions are now 2.6, 2.7 and 3.2.
New Features¶
Added support for reading the opaque attribute from <transparent> tag.
Normals and texture coordinate indices are now available in shapes (Triangle and Polygon).
Library is now compatible with python’s built-in ElementTree API instead of requiring lxml. lxml is still recommended.
Added support for Python 3.2. Supported versions are now 2.6, 2.7 and 3.2.
Added support for index_of_refraction in <effect>.
Added optional parameter to Collada that does XML schema validation when saving.
Automatically corrects broken files that don’t have correct xfov, yfov, and aspect ratio in cameras.
Bug Fixes¶
Fix the default value for transparency in Effect. Now correctly defaults to 1.0 when opaque mode is A_ONE, and 0.0 when opaque mode is RGB_ZERO.
Fixed bug where BoundPolylist was not returning the correct length value.
Removed support for RGB from Effect since it’s not valid in the spec. If an RGB is given, a fourth A channel is automatically added as 1.0.
Made instance_geometry not write an empty bind_material if it’s empty since it breaks validation.
Made saving strip out empty <library_*> tags since it breaks validation.
0.3 (2011-08-31)¶
Backwards Compatibility Notes¶
If using the old Camera object, this has been changed to an abstract class with types for PerspectiveCamera and OrthographicCamera
If using the old Collada.assetInfo dictionary to read asset information, this has been changed to an object. See documentation for more information.
New Features¶
Added support for bump maps inside the extra tag of an effect
Added texbinormal and textangent to triangle sets
Added a method to generate texture tangents and binormals
Added detection for double_sided
Added an optional parameter to specify what filename inside an archive to use when loading from zip
Added support for loading multiple sets of library_* nodes
Refactored asset information into a separate module. Fixed #12
Refactored Camera into PerspectiveCamera and OrthographicCamera, inheriting from Camera
Bug Fixes¶
Changed Collada IndexedLists attributes to be properties. Fixed Issue #14
Updated scene to use a local scope when nodes are instantiated inside a scene
Changed parsing to raise DaeMalformedError when an lxml parser exception is thrown
Fixed bug when loading an <image> tag local to an <effect> not showing up in Collada.images
Fixed bug when loading an empty <polygons>
Fixed bug in if statement when loading morph controllers
Fixed bug when triangulating a length-0 polylist
Updated install instructions for OS X and Ubuntu problems
Fixed bugs in IndexedList from Issue #13
Fixed a bug where using the same map twice in an effect would cause incorrrect output
Changed geometry export to delete any sources in the vertices tag that no longer exist
Changed library output to not output empty library nodes so validator doesn’t complain
Add same checks in scene loading that was done in library_nodes loading so that if nodes are not found yet while loading, it will keep trying
Changed the way library_nodes is loaded so that if a referenced node from instance_node is not loaded yet, it will keep trying
Fixed bug where a triangles xml node would try to set an attribute to None
Fixed bug in handling joints that influence 0 vertices
0.2.2 (2011-05-03)¶
Changed the way instance_node is handled to actually maintain the mapping so it’s not lost when saving
Added setdata function to CImage and made Effect compare only image path
Fixed a bug when rewriting geometry sources
Change primitive sources to point to the <vertices> tag when possible since other importers don’t like not having a <vertices> tag
Export source data with only 7 decimal precision for better file size
Prevent NaN from being the result of a normalize_v3 call
Fixed bug where effect was not correctly reading all four color values
Fixed a bug where a triangleset would not create its xml node when generated from a polylist
Big speed increases for converting numpy data to strings
Moved getInputs function to Primitive
Added functions to triangleset to generate normals and get an input list
Fixed bug in saving a scene node if there was no id
Fixed some bugs/optimizations with saving
Added function to test if an Effect is almost equal to another Effect
Adding dynamic dependencies to setup.py
