iDocument::Parse() method now accepts an optional argument
indicating whether or not extraneous whitespace in `CS_NODE_TEXT' nodes
should be condensed. Most implementations of `iDocument' will attempt to
respect this option if possible. For implementations where it does not make
sense, the option will be ignored.
Previously, XML-based implementations of the `iDocument' interface
condensed whitespace in `CS_NODE_TEXT' nodes at
Parse() time. This
is no longer the case. Whitespace is now preserved by default. If the new
behavior is unsuitable for your case, use the new argument to
iDocument::Parse() to indicate that whitespace should be condensed.
This change was made in order to conform to the latest XML specification
which states that XML scanners must preserve whitespace by default.
Consult the following documents for more information regarding this issue.
The mesh factory interfaces (`iGeneralFactoryState', `iHazeFactoryState', `iInstancingFactoryState', `iLightningFactoryState', `iSprite2DFactoryState', `iThingFactoryState' and `iSprite3DFactoryState' no longer have the following methods. Use the methods with same name from `iMeshObjectFactory' instead:
From `iGeneralMeshState', `iInstancingMeshState', `iRainState' and `iParticle' the following methods have been removed. Use the methods with the same name from `iMeshObject' instead.
The `iImage' interface has been reduced to a level where it merely serves as a container for pixel data; however, the image editing functionality was only relocated, not removed.
Forbidding direct manipulation of an `iImage''s pixel data has the following consequences:
Clone()function was removed. The `csImageMemory' class provides a constructor that copies the pixel data from another `iImage' object, providing a functionality equal to
SetFormat()call has been removed from the interface.
Sharpen()was moved into the `csImageManipulate' class.
CopyXXX()method that copied an image into another are now provided by `csImageMemory'.
As a side-effect of these changes, the `csImageFile' and `csImageMemory' were merged and the former removed.
iImageIO::Load() now requires the image source data in an
`iDataBuffer' object, instead of separate `buffer' and `size'
The `iLight' and its implementation (`csLight') have been extended to also handle spot- and directional-lights. Note that the accual computation of lighting does not yet support these, however the engine can now store and handle the required data.
There have also been two smaller changes to the interface to make it more
coherent. The influence radius have been renamed cut-off distance, and
thus the methods
have been renamed accordingly to
SetCutoffDistance(), respectively. Also,
been renamed to
SetAttenuationMode() in order to avoid confusion with
other similary named methods. For the
CS_ATTN_LINEAR attenuation type
the specification has changed slightly. As a default, the distance where light
goes out is same as the cut-off distance, but this can be changed by altering
the first attenuation constant. See comments in
`CS/include/iengine/light.h' for exact details of the different
From `iParticleState', the following methods have been removed. Use the methods with the same name from `iMeshObject' instead.
iMaterialList::NewMaterial() now needs an additional
name parameter. It is not recommended to change the name later.
The function `iObjectModel::GetObjectBoundingBox()' only has one
parameter now. The optional `type' parameter has been removed as it
was not implemented anywhere. In addition to that the constants
are also removed.
Some methods from `iSprite3DState' have been removed that basically provided functionality which was also already available through `iMeshObject':
GetFactory() method has been removed from
`iThingState'. Equivalent functionality can be achieved by using
GetFactory() from `iMeshObject' and querying the returned object
for the `iThingFactoryState' interface. Example:
csRef<iThingFactoryState> thing_fact_state = scfQueryInterface<iThingFactoryState> (mesh->GetMeshObject () ->GetFactory ());
iTextureManager::FreeImages() has been removed. It was used to release
the `iImage' objects associated with textures with the purpose of freeing
up memory. This happens automatically now; the images associated with a
texture are released by the renderer as soon as the image data is converted
into the internal texture format (that is, uploaded to the graphics hardware).
