+	Release Notes for the Lightwave 3D Java3D Loader
+	------------------------------------------------
+			Updated May 13, 1998
+
+
+
+These release notes are intended to document the known working and
+non-working features of the loader.  This is important because the loader
+implements an important subset of Lightwave functionality, but it definitely
+skips many major features of Lightwave files.  Please read these notes
+to make sure that the features you need are actually implemented.  Or
+if you see differences between Lightwave display of your file and
+the Java3D version of that file, take a look at these notes to see
+what might not be working properly.
+
+
+Testing the Loader
+------------------
+The application in this directory (Viewer) is intended to be a very
+basic test application for loading/viewing Lightwave 3D models.  To
+use the program, type:
+	java Viewer <filename>
+where <filename> is the name of a valid Lightwave 3D scene file that is
+reachable from the current directory.  There is a very basic test file
+included in this directory called ballcone.lws.  To load/view that file,
+type:
+	java Viewer ballcone.lws
+Note that Lightwave scene files (*.lws) embed the pathnames to object
+files (*.lwo) within them, and that object files have pathnames
+to image files (for textures) embedded in them.  Whatever those
+pathnames are in those files must be valid for the directory in which
+you are running the application that loads the scene file.  For example,
+if I was loading in a scene file that referred to an object file 
+called "data/object.lwo", then the file "object.lwo" should be located in
+a subdirectory of this current directory called "data".
+
+
+Summary of Loader
+-----------------
+The Lw3d loader was intended to implement a major subset of the features in
+Lightwave 3D that would be used for realtime 3D animations.  That is, any
+features (such as Bones and other high-end rendering
+options) which would require significant rendering time were simply
+not doable.  These more advanced features are intended to be rendered
+off-line, saving each frame separately and later compositing them
+together into an animation.  But Java3D is a realtime 3D rendering
+system, so these type of animations just do not map into a Java3D viewer
+very well.
+
+Another category of non-implemented items are those that we simply have not
+yet gotten to.  There are a few known features of Lightwave files that
+would work well through Java3D but just haven't been implemented in the
+loader yet.
+
+Although there are a lot of features that are not yet implemented,
+the basics of Lightwave 3D functionality (scene creation, animating
+objects/lights/cameras, different surface properties) all work pretty
+much as expected.  So try it out and let us know non-documented items
+that didn't work properly.
+
+
+Details of Non-Implemented Features
+-----------------------------------
+This list is probably not comprehensive, but hopefully points out most of
+the features or areas where the implementation is incomplete (or not
+there at all).
+
+
+Limitations of Scene Files (*.lws)
+----------------------------------
+1) Bones/Skeleton
+Bones functionality is not implemented at all.  Unfortunately, this
+great feature of Lightwave 3D is not currently implementable in the
+loader because the processing time that it would take to compute
+frames based on Bones data would be far more than a real-time rendering
+system can afford.
+
+The loader may, at some future point, provide a mechanism to read
+in frames of geometry that were saved from Lightwave Bones descriptions.
+That is, there are plug-ins available for Lightwave 3D that allow you
+to save out files with Bones information as a series of files with
+pre-calculated geometry for each frame; eventually we would like the
+Lightwave 3D loader to support those files.
+
+Workaround: None; the best and only workaround is to find a different
+method of animating your objects.
+
+
+2) Spline paths
+Spline paths will be interpreted as linear piecewise paths instead,
+traveling between each control point specified for the spline.
+
+Workaround: Specify linear paths.  If your path looks too hard-jointed 
+through the loader, specify more keyframes for the path to smooth it out.
+
+
+3) Object Scaling
+Scaling objects in the scene (versus the object files) is currently
+ignored.
+
+Workaround: scale the objects in their individual object files.
+
+
+4) Shadows
+Shadows options are ignored in the loader.
+
+Workaround: None.
+
+
+5) Envelopes
+Most envelopes are ignored.  There are a couple of exceptions to this,
+such as light intensity envelopes, but even those features have not been 
+completely implemented and tested.
+
+Workaround: None.
+
+
+6) Camera effects
+All advanced-rendering camera effects are ignored in the loader.  This
+includes the following items in Lightwave 3D files:
+	- Lens Flare
+	- F-stop
+	- Focal Distance
+	- Blur Length
+	- Dissolves
+	- Glow
+	- Zoom
+	- Intensity Falloff
+	- Antialiasing
+	
+Workaround: None.
+
+
+7) Inverse Kinematics
+IK options such as Goal Objects and Anchors are ignored.
+
+Workaround: Animate objects directly instead of indirectly via IK.
+
+
+8) Morphs
+All morph options are ignored.
+
+Workaround: None.
+
+
+9) Display properties
+Lightwave allows you to specify surface properties for different rendering
+modes (e.g., wireframe color).  All of these parameters are ignored and
+the full properties of any item are used at all times.
+
+Workaround: None.
+
+
+10) Various Surface Properties
+Various minor surface properties are currently ignored, including:
+	- Polygon size
+	- Dissolves
+	- Clip map
+	- Unaffected by fog
+	- Edge parameters
+
+Workaround: None.
+
+
+11) Lights
+The following items are currently ignored for Light objects:
+	- Target objects
+	- Flare parameters
+	- Shadow options
+
+Workaround: None for flares or shadows.  For targeting problems, animate the
+light directly (versus indirectly through using Target).
+
+
+12) Camera Targeting
+The Target option for Camera objects is currently ignored by the loader.
+
+Workaround: Animate the camera directly (versus indirectly through using
+Target).
+
+	
+13) Effects
+Most effects (from the Effects dialog box in the layout program) are
+ignored, save for fog (which should accept all parameters) and 
+backdrop colors (solid backdrops only - gradient backdrops are
+ignored).
+
+Workaround: None.
+
+
+14) Render Options
+Most options from the Render dialog box are ignored - most of these pertain 
+to saving the animation in any case (something that doesn't happen through
+the Loader).
+
+Workaround: None.
+
+
+
+Limitations of Object Files (*.lwo)
+-----------------------------------
+1) MetaNURBS
+Geometry stored in MetaNURBS format will be ignored by the loader.
+
+Workaround: pre-tessellate your MetaNURBS surfaces and save your
+geometry (object) files in that format.
+
+
+2) Layered Object Files
+There is currently no support for the "Layered Object File Format" 
+of Lightwave 3D.
+
+Workaround: None.
+
+
+3) Reflectivity
+There is no way to reproduce the reflective properties of surfaces
+through Java3D, so any reflectivity settings in Lightwave object files 
+will be ignored.
+
+Workaround: None.
+
+
+4) Refraction
+Refractive properties of surfaces are ignored.
+
+Workaround: None.
+
+
+5) Edge Transparency
+Edge transparency properties are ignored.
+
+Workaround.  None.
+
+
+6) Texture types
+Texture mapping is currently somewhat limited in the loader.  The following
+types of texture mapping effects should work:
+	- Diffuse (the texture modifies the Diffuse aspects of the surface)
+	- Color (the texture modifies the Color properties of the surface).
+Textures that attempt to modify other parameters of the surface will
+be ignored.
+
+Also, the following texture types should work:
+	- Planar Image Map
+	- Spherical Image Map
+	- Cylindrical Image Map
+Other kinds of mappings will not work (including Marble, Grid, Dots, etc.)
+
+Some Texture parameters will not work.  The following should work correctly:
+	- size
+	- center
+Advanced texture parameters such as falloff and velocity will be ignored.
+
+Summary: There are so many texture mapping parameters in Lightwave 3D that 
+it's difficult to produce a list of all of the items that won't work
+properly.  In a nutshell, basic decal-type (color modifying) or brightness
+(diffuse modifying) textures that are mapped as planes, spheres, or
+cylinders should work correctly.  Anything else will probably not work.
+
+Workaround: Use the basics.
+
+
+7) Plug-ins
+There is currently no support for any plug-in capabilities.  For example,
+if there are plug-in shaders specified for your file, those shaders will be
+ignored.
+
+Workaround: None.
+
+
+8) Image Sequences
+There is no support for image sequences - textures must be static files.
+
+Workaround: None.
