• Fixed a problem where floating point errors could happen when creating UV coordinates.

• RWX files are converted faster.

• Reading OBJ files: Fixed a problem where some data was lost because the line termination characters were changing in the file.

• Reading DXF files: Fixed a problem that caused some mesh data to be lost when DXF blocks were inserted in other DXF blocks.

• Added writing of a 3D model to a XYZ file.

Version 2.9.20: July 16, 2006

• When reading LightWave LWO2 files and a layer using multiple surfaces is divided into several layers, the names for the new layers will be a combination of the original layer name plus the surface name instead of just the surface name.

• Fixed some errors that occurred when reading the "KamaKazi Kube" OBJ files.

• When writing RWX files, the Vertex keyword is written instead of the VertexExt keyword.

Version 2.9.19: July 2, 2006

• When reading OBJ files, if a material is used several times only one layer is now created instead of multiple layers.

Version 2.9.18: May 3, 2006

• Shortcut added: To deselect a layer, place the cursor over the layer in the OpenGL view window and while holding down both the 'shift' and 'ctrl' keys click the right mouse button.

• Fixed a problem when reading LightWave files. If a surface using a UV texture was assigned to more than one layer the textures were not displayed correctly.

• Added support for saving the 3D object rendered in the view window as a thumbnail bitmap. Also added a batch mode for creating thumbnails for all the 3D files in a folder.

• Added a routine to convert bitmap files to XYZ files.

• Added a batch routine to create objects containing clip maps and to save them as LightWave LWO files.

Version 2.9.17: March 18, 2006

• Fixed a problem when inserting blocks in DXF files. Quads could not be displayed correctly and exported to files.

• XGL, ZGL files: Added support for reading meshes stored as instances \ prototypes \ blocks in the file.

Version 2.9.16: March 14, 2006

• Fixed a problem with reading vertex normals from Wavefront OBJ files.

• Fixed reading of USGS SDTS files. The reading of this file format was not updated in version 2.9.15 when regions were added to the landscape database.

• In the 'Edit Vertices' module, scroll buttons have been added for moving or translating one or more vertices and for rotating and scaling of a group of vertices.

• Added a 'Triangle Delete' module so that triangles can be selected and deleted from the layers.

• Added a 'Triangle Fracture' module which fractures or divides each selected triangle on a layer into three triangles. The 'Divide Triangles' module was renamed 'Triangle Divide'.

• Animations: A range of frames can now be deleted. A range of frames can be copied and inserted at the currently selected frame.

• VRML files: Added support for reading texture file names and texture transforms in prototype nodes. Fixed a problem when reading the Switch node.

Version 2.9.15: February 7, 2006

• Added a new feature that allows for moving triangles and quads from one layer to either another layer or to a new layer.

• VRML files : Fixed a problem with reading the Switch node and another problem that could prevent the VRML material properties and the texture name from being applied to the layer.

• Fixed three problems (space in file name, quotation marks around file name and tab character) that could prevent the MTL file referenced in the OBJ file from being read.

• Added support for RWX avatar tag numbers from 43 to 54 which are scheduled for addition to Active Worlds browser 4.1.

• The landscape can be saved to a DXF file as contour lines with a user specified contour interval.

• A region or smaller area can be set for the landscape and the region can be saved to any of the 3D file formats. The size and position of the region can be changed without reloading the landscape file.

Version 2.9.14: December 24, 2005

• Fixed a problem that caused the OpenGL viewer to crash on computers using the Windows 9x Operating Systems.

• For any 3D object, a layer can have it's pivot point changed. The layer can be rotated or scaled about it's pivot point and be moved to a new position.

• Selected layers and their polygons, lines and points can be copied from one Work Area to the clipboard and then can be pasted into a different Work Area.

• An avatar can be written to a RenderWare RWX file in a format that can be converted by the rwxtobod.pl script to make a BOD file that can be used in the WorldsPlayer browser.

• Added writing of UV texture coordinates to Lightscape LP files.

• Fixed a problem where the wrong polygon flag was written for quads to LP files for Lightscape Version 3.2.

• Added reading of Tag Image File Format TIF files.

• Reading 3DS files: Fixed a problem created in version 2.9.12, where multiple materials on a layer could cause the key frame data to be applied to the wrong layer if duplicate layer names were created.

• Fixed a problem where one or more triangles could have their surface normal flipped, when a polygon with holes was triangulated.

• DXF files: Added support for the ELLIPSE entity: Fixed a problem that could cause the bulge to be deleted when duplicate vertices were deleted for the POLYLINE and LWPOLYLINE entities.

Version 2.9.13: September 5, 2005

• Texture files can be copied from their original folders to a new folder. An option allows supported texture file formats to be saved to another supported texture file format during the copy operation.

• Added an optional header for XYZ files.

• Adding reading and writing of ArcInfo ASCII Grid files.

• Added reading and writing of Portable Network Graphics, PNG, files and reading of Graphics Interchange Format, GIF, files.

• Added writing of Open Inventor 2.0 files.

Version 2.9.12: June 19, 2005

• Changed how the axis system is handled for STL files so that the object is not mirrored on the Z axis (Y axis in AccuTrans 3D) in STL files.

• RWX files: Tags for clumps and triangles / quads are now handled separately.

• All layers that contain multiple materials are now automatically divided when a file is read.

• Faster reading of a set of VRML files that contain thousands of IndexedFaceSet nodes and that were created by Pro/ENGINEER.

• The option to write a reversed polygon to 3D Studio, LightWave, VideoScape and Wavefront files to create double sided polygons has been removed.

• When writing RWX files, only the keyword 'AddMaterialMode Double' is used for double sided polygons. The option to write a reversed polygon to the file has been removed.

• Aligning surface normals: New buttons added plus the align modes can be toggled by holding down the shift key and clicking the left, middle and right mouse buttons.

• Select a new pivot point in the OpenGL window to rotate the object about by positioning the cursor over the spot and clicking the middle mouse button. To return the pivot point to the center of the object, position the cursor over an empty area of the view window and click the middle mouse button.

• New zoom mode added which uses the mouse scroll wheel. Also toggle between the 3 zoom speeds by holding down the shift key and moving the scroll wheel.

• Quads that are read from a file are now stored as both quads and triangles in the AccuTrans 3D database.

• Layers can now be selected in many modules by moving the cursor over the object in the view window and clicking the right mouse button. In the 'Layer Transfer' module, holding down the shift key and clicking the right mouse button also selects a layer.

• Added reading of SBP files produced by the ShopBot digital probe and converting the data to a polygon mesh.

Version 2.9.11: March 1, 2005

• The texture parameters used to create UV coordinates for each layer can now be read and saved to an AUV file.

• RWX prototype names are now used for the layer names. The optional layer name is now written after the RWX ClumpBegin command and used for the layer names when the file is later read by AccuTrans 3D.

• When adding files, the original file name is maintained as additional files are added. Added the option of using the file name as a prefix rather than a number.

• Added new options for adjusting layer names on the "Layers" menu.

• Fixed a problem where some polygons were not read from LightWave LWO2 files.

• Added "drag and drop" support to open files selected in Windows Explorer and dropped anywhere on the AccuTrans 3D window or on the AccuTrans 3D icon on the Windows Desktop.

Version 2.9.10: released January 31, 2005

• Added option to change texture or mask on one layer and simultaneously change the identical texture or mask used on other layers. Change the attributes on one layer and then copy them to all layers using the same texture and mask.

• Added writing of multiple layers as a single layer with multiple materials to DirectX, LightWave, RenderWare, Softimage, StereoLithography, trueSpace, XGL and ZGL files. Note: STL files only use one material.
