=========================================================================== GLView version 2.09 15.06.96 3D OpenGL Viewer for Windows NT 3.51/4.0/95 Copyright (C) 1994-1996 Holger Grahn All Rights Reserved =========================================================================== See the file README.TXT for installation instructions and last minute notes. For ordering information, see the file ORDER.TXT. The following changes were made in the GLView 2.09 (15.06.96) version * rendering of VRML to a BMP file in arbitrary resolution (File->RenderToFile) great for web-page image generation, creation of textures, printing .... * support for Layer Node to compose displays with underlay and overlay nodes. a layer can contain (blended / transparent) images or even full 3d VRML scenes (See LayerTest.wrl) * Image and ScaledImage node to display 2D images including alpha support (See ImageTest.wrl) * BackgroundImage support (implemented using Layer + ScaledImage nodes) * ImageElevationGrid creates a heightfield or 3D surface simply from an standard pixel image. 2d-paint programs could be used to create 3D landscapes. (See ElevatedMandril.wrl) * Save to wrl for single object scenes preservers Material, Background Color/Image, Texture settings (but with absolut pathnames to textures, filenames need to be changed to relative one manually for web-page publishing) * bug fixes * automatic adaption of default znear plane to z-buffer depth (means better 16 Bit z-buffer support) * dummy declaration of Kinetix 3D Studio Max exporter nodes * rotation field for morph node * demo version expires after a month * in Options->Register Filetypes GLView can be (re)registered automatically as Netscape viewer for mimetypes x-world/x-vrml and x-world/x-glview * additions to tree editor: New Nodes can be created via "Node->New" entering a node type or choosing from a listbox On double-click on a field in the tree view an field editor pops up SFColor + MFColor length 1 fields can be editited using the color editor Paste In allow the paste of nodes into Group nodes or SFNode fields * save of VRML to raw/pov/stl/geo dosnīt destroy internal tree structure * raw input supports mixed in ascii lines The following changes were made in the GLView 2.08 (24.04.96) version * fixed the "IntenetOpen Error 2" bug occured on some Windows 95 installation * user interface improvements * URL status bar + animation during internet operations * additions to Morph node, eg. time range control (e.g. MorphedVenus.wrl) * new color gradient animation node (See Colored*.wrl) * first version of VRML 2.0 extrusion + heightfield node (ExtrusionTest.wrl + Landscape.java) * 16 Bit Z-Buffer switch + OpenGL info box * save window size on exit option * support for Transformed Cameras (Fountain) * HTTP + FTP protocol Internet access now through Microsoft Internet SDK The following changes were made in the GLView 2.07 (08.03.96) version * HTTP + FTP protocol Internet access now through Microsoft Sweeper SDK * url loading using multiple parallel background threads * first version of VRML tree inspector / editor (Tools->Tree Editor) (Not all editing commands are available in the Demo Version) * full write for VRML scenes * support for filenames with spaces (C;\Program File\mywrl.wrl) * changed extensions of GLView url Internet Shortcut to vrl, because Microsoft Internet Explorer uses same extension * file type associations now editable (Options->register file types) * configurable limitation of texture size in Material->texture options * camera relative switch, enabled: movement is relative to view direction (like a airplane) disabled: movement is relative to the world "up" direction (like walking on a plane * changed Cylinder, Cube, Cone, Sphere texture coordinates from XYZ frame to VRML xzy frame * faster texture loading for pover of 2 sized textures * fixed a bug during Font tesselation * other bugfixes The following changes were made in the GLView 2.05 (15.12.95) version * user interface additions, more toolbar buttons, better defaults for VRML browsing * new VRML nodes TimeTransform, TextureShuttle * support for nested relative WWWInlines * registry file type association on demand only, * dragging files from the filemanager to a running GLView * url files now contain the source url caused the loading * textures can now be loaded automatically at first load of the url (WWW->Options->Texture) * global light scale factor to, scale down to bright VRML scenes (Some files contain too many unnecessary lights) * bug fixes and small enhancements The following changes were made in the GLView 2.03 (28.11.95) version * some defaults changed The following changes were made in the GLView 2.02 (21.11.95) version * Netscape DDE Support * VRML Spheres can be now textured * VRML files from cache are verified for correct URL * better support for Home Space Builder VRML files (e.g. Render Mode non-lighted) The following changes were made in the GLView 2.01 (13.11.95) version * support for WWWAnchor display during mouse move + * left mouse button double click jumps to anchor * optional view degration during moving (enable via Options->Config->degrade) * VRML bug fixes * Texture/image loading bug fixes: bug on non 4 byte aligned images, bug during gif,jpeg,tga loading * new morph type cone, transformations and box now working, see Morphed*.wrl files The following changes were made in the GLView 2.0 (26.10.95) version * compiled with MSVC 2.2, Windows NT 3.51 * support for VRML nodes in GLView scene database * automatic triangulation of indexedFaceSets if ShapeHints.faceType == UNKNOWN_FACE_TYPE * Vrml loading from file / World wide web * WWW menu * VRML Extensions Nodes BaseColor, Shuttle, Rotor, TextureRotor, Morph, Blinker AsciiText 3D Extruded text * Texture Options: perspective correction * Additional support for GIF, JPEG, TARGA texture/image files * minor modificiations for Windows 95 The following changes were made in the GLView 1.2 version * unzipping of files with .gz suffix * new Morph class * changes on camera interaction * Commandline file/url argument * Automatic association for known extensions with GLView in the system Registry (HKEY_CLASSES_ROOT) The following changes were made in the GLView 1.11 version * color map now correct on first run & window change (256 color drivers) * new File-> New Logo command to create 3D flyling logos using Windows True Type fonts * new Tools->Triangulate command to triangulate faces of current object using the GLU-Triangulator * new Tools->Info command to display some info and statistics on current object * new options->config "draw front", if checked rendering goes directly to screen, so rendering is visible (usefull to compare speed, for drawing complex objects or wireframe rendering) * new options->config "zoom by 2", if checked rendering is done half the window size, and pixels are copied to screen zoomed by 2, unfortunately the OpenGL zoom copypixel function is very slow !? * new options->update colors if checked (default): in the case focus is changed to another window with a custom palette, all pixels in the GLView window are replaced to the nearest matching new palette entry, also animation is disabled. * vrml out, stl out, geo out The following changes were made in the GLView 1.1 version * compiled with MSVC 2.0, Windows NT 3.5 * File new allows creation of different object types * fixed a bug in mesh face normal computation * raw + pov triangle output * DXF File (ACAD R 11) import + Tree database + Combine command * limited save as functionality in evaluation version The following changes were made in the GLView 1.0a version * flipping of object normals (Rendering->Options->Flip object normals) for "dark" objects. * group support for Wavefront obj files * group support for some primitives * group color setting by names (X11 color names) The following changes were made in the GLView 1.0 version * support for RAW input format (RAW contains simply one triangle per line) * optional building of triangle strips for better OpenGL drawing speed (can be enabled via the options dialog, must be enabled before reading a file) * detailed rendering style control for vertices, edges, faces, normals * more toolbar buttons GLView 0.9 initial version
