Changes to the Program

 

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.
