                      | Version 2.8.21: released December 9,
                        2003 
                          3DMF files: Added writing of TriMesh.
                            Pixmaps can now be saved at pixel sizes of RGB16 and
                            RGB24 as well as the previous RGB32. 
                          Added support for masks for RWX and 3DS
                            files. Display of masks in the OpenGL viewer will be
                            added at a later date. 
                          Reading 3DS files: Fixed the direction
                            of surface normals for mirror objects. Added support
                            for floating point colors and percentages for materials. 
                          AccuTrans 3D can now be associated with
                            a file type in Windows Explorer so that
							
                              right clicking on the file name, the
                                'Open with' menu item can be used to open the file
                                in AccuTrans 3D. 
                              double clicking on the file name opens
                                the file in AccuTrans 3D. | 
                    
                      | Version 2.8.20: released November 15,
                        2003 
                          Fixed a problem that had the CPU at 100%
                            usage when an object was not being displayed in the view
                            window. 
                          After clicking the 'OK' button in the
                            'Windows Save As' dialog box if the file name does not
                            have a file extension one is added. | 
                    
                      | Version 2.8.19: released November 12,
                        2003 
                          Fixed a problem when reading avatars from
                            RWX files: The joint position was overwritten by the
                            center point of the layer. 
                          Added writing of XGL files. 
                          Layer material properties known as ambient,
                            reflection, specular and transparency are represented
                            by both RGB color properties and single value properties.
                            The RGB color properties are now linked to the single
                            value properties. | 
                    
                      | Version 2.8.18: released November 1,
                        2003 
                          Added the creation of UV texture coordinates
                            based on planar, cylindrical and spherical texture mapping. | 
                    
                      | Version 2.8.17: released October 24,
                        2003 
                          Changed OpenGL viewer startup so that
                            it does not execute until after the main window is displayed. 
                          3DS Files: Objects are positioned and
                            cloned according to data read from the key frame section
                            of the file. | 
                    
                      | Version 2.8.16: released October 16,
                        2003 
                          Changes made for reading of DXF files
                            for the extrusion module. 
                          VRML files: Added support for textures
                            on the box, cone, cylinder and sphere primitives and
                            the ElevationGrid node. Also added support for the TextureTransform
                            node. When a landscape is written as an Elevation Grid
                            node, UV texture coordinates can now be created and saved
                            to the file. 
                          POV-Ray files: Changed to writing version
                            3.5 files and added writing of normals and UV texture
                            coordinates. | 
                    
                      | Version 2.8.15: released September 9,
                        2003 
                          In the 'Adjust Object' module, added controls
                            so that the location of the origin in the 3D object can
                            be adjusted using the mouse. | 
                    
                      | Version 2.8.14: released August 29, 2003 
                          Landscape elevations can now be scaled. 
                          Elevations less than zero meters can now
                            be saved to VistaPro files. | 
                    
                      | Version 2.8.13: released August 17, 2003 
                          Faster reading of LightWave files that
                            use UV texture coordinates. 
                          Fixed a problem where the OpenGL viewer
                            did not display large bitmaps. | 
                    
                      | Version 2.8.12: released August 11, 2003 
                          The 'Open As', 'DXF' and 'VRML' pages
                            have been removed from the 'Tool Palette' and replaced
                            with the 'Open With Options', 'Segments Per Arc' and
                            'VRML Primitives' dialog boxes. 
                          Added a vertical toolbar. 
                          Button size has been increased to 28 x
                            28 pixels for better visibility on screen sizes larger
                            than 800 x 600. 
                          In the avatar module, the Green Man group
                            of buttons with pictures of body parts on them has been
                            replaced by one button with multiple hot spots. Each
                            hot spot surrounds a body part. 
                          Added support for tags 31 to 42 for Active
                            Worlds avatars. 
                          Tag numbers 30, 40, 100 and 200 can be
                            set for the layers and saved to RWX files. 
                          When converting triangles to quads, the
                            angle between the edges will now be checked. The check
                            value is user adjustable. | 
                    
                      | Version 2.8.11: released April 5, 2003 
                          Fixed a problem where a binary SEQ file
                            that started at frame 0 instead of frame 1 was not read. 
                          VRML files:
						    
                              Fixed problem where crease angles were
                                not always read. 
                              Crease angles for primitives converted
                                to 3D meshes can now be set. 
                              Added reading of PointSet nodes. 
                              Added reading of Inline nodes for VRML
                                1 files. 
                              Fixed problem when reading normals. 
                              Fixed problem with clockwise and counter
                                clockwise ordering of vertex indices for triangles. 
                          Fixed a problem that occurred when texture
                            file names contained spaces. 
                          Added flag to control writing of texture
                            paths to files. 
                          Added option to display or not display
                            warning messages when writing StereoLithography files. 
                          Fixed problem that prevented reading of
                            some 3D Studio ASC files and another problem that prevented
                            reading of some Imagine IOB files. 
                          Contour lines stored in DXF files can
                            now be converted to a landscape. 
                          Code redone for checking size of objects
                            being written to files and dividing objects that are
                            too large. 
                          The default layer name used for constructing
                            layer names when reading some file formats is now user
                            adjustable. 
                          When a file is read, the layer names are
                            no longer converted to all uppercase. 
                          Fixed problem where a NAN, not a number,
                            present as a UV texture coordinate in a file caused a
                            crash. 
                          Added writing of normals to Maya MA files. 
                          The group of controls for setting maximum
                            limits for vertices, edges and triangles for file formats
                            in the 'Save Object As' dialog box has been removed. | 
                    
                      | Version 2.8.10: released February 2,
                        2003 
                          Fixed a problem where negative UV texture
                            coordinates were not correctly converted to positive
                            values when writing RWX files. 
                          Added writing of DirectX files and Softimage
                            dotXSI files. The version 3.5 dotXSI files were tested
                            in the Softimage | XSI Viewer, version 3.6.1. 
                          Fixed problem where the material properties
                            could be assigned to the wrong layer when dividing an
                            object from a 3DS file. 
                          The 'Flip YZ' check box was removed from
                            the 'Save Object As' dialog box. |
