Open Inventor Tools Issues

From MerlinWiki

This page lists known bugs, extensions and changes in Open Inventor Tools.

Known Bugs

VRML2/97 models: some utilities does not work correctly with them

Particularly, ivfix and ivAddVP are known to not handle VRML2/97 nodes correctly.

Workaround: use ivvrml to convert files to Inventor format.

Extensions for 2.0 Release

ivperf outputs HW info

Texture images are not loaded for all command-line utilities

They are not needed since the usitilies are doing just geometry processing. It brings speed-up and the user is no longer bothered by error messages of images, that can not be loaded.

Known issues:

• Coin-2 contains bug causing ivvrml still generate some error messages about missing image files.
  Status: Fixed in Coin 2.4.5 release (fixed in cvs at: 2005-02-22).
• This extension does not avoid bug of missing textures of ivvrml when exporting to VRML2.

ivToInclude added

ivperf profiler

• added scene graph profiling capabilities

Known issues:

• SoVRMLInline does not work. Reason: private destructor.
  Status: Fixed in Coin 2.4.5 release (fixed in cvs at: 2005-02-22).

• major meassuring algorithms overhaul

ivgraph added

prints scene graph tree

Known Bugs in 1.0 Release

ivvrml: NodeKits and interaction nodes did not worked

Status: resolved. Will be available in 2.0 release.

ivvrml: Missing textures (Coin bug)

This concerns just a conversion to VRML2/97.

If a texture node refers to a non-existing file, everyone could expect that everything will be ok since nothing is visualized. However a bug in Coin caused the texture to not appear in destination file when converting to VRML2/97.

Status: Fixed in Coin 2.4.5.

Workaround: provide the converted file with all textures that the file references

ivperf: fails on VRML2/97 models (Coin bug)

The ivperf fails with assert on some models containing VRML2/97 nodes. It happens in SoNode::copyContents function that behaves differently between SGI Inventor and Coin.

Status: Fixed in Coin 2.4.5 release (fixed in cvs at: 2005-02-03).

Workaround: run ivfix utility on the models (that will remove all VRML2/97 nodes).
