Release Notes Version 1.20.8

krpano 1.20.8 (2020-09-15)

  • New: Experimental support for using textured 3D-Models instead of depthmapped-panoramic images (Example). Such 3D-Models could be generated using Blender and the PanoCamAdder Add-on (or any other 3D-Modeling software). Potential usage cases would be better and more complete 'Dollhouse views', nicer 3D-scene-transitions and eventually also a mixed display together with a higher-resolution panoramic image.
    Note: the details, xml/usage-API and performance of that feature is still work-in-progress and will change with the next releases.
  • New: Support also the Wavefront OBJ file-format for Depthmap 3D-Models. It is similar to STL, but additionally also supports texture-mapping information.
  • New: Support RGB-encoded 16- or 24bit depthmap images for more precision (Feature Request, Example).
  • New: Special import settings for Depthmap 3D-Models: depthmap.axis, depthmap.cull and depthmap.center. They can be used to align the 3D-Model correctly for usage inside krpano. These settings work for STL, OBJ and DEPTH files and replace the previously undocumented and STL-only stlaxis, stlscale, stlmove and stlrotate settings.
  • New: depthmap.waitforload setting to tell the viewer to wait with the rendering/displaying until the depthmap is loaded and ready. Without that setting the pano would be shown in spherical or cubical projection until the depthmap is ready.
  • New: Improved xml file loading performance: <include> files will be loaded in parallel and duplicated load requests automatically be merged and cached. With this the startup time will be reduced, especially when including a lot additional xml files.
  • New: WebVR Zooming Plugin: webvr_autozoom.xml - just include it and automatically get zooming support in VR (Example).
  • New: A setting to customize the user control friction stop/cutoff-speed: control.frictionstop That setting is a relative factor that defines at what movement speed the movement should completely stop. Additionally the default value for this setting has been reduced, in previous versions it was 0.04, now it is 0.01, that means a slightly smoother fading out of the movement.
  • New: Support external mouse control on touch devices (iOS 13.4+ and Android). Can be optionally disabled by the touchdevicemousesupport setting.
  • New: isset() and isvalue() expression functions for easier checking if a variable is existing and if its value is not an empty string.
  • New: Support the 3D translations (image.ox/oy/oz, view.tx/ty/tz/ox/oy/oz, hotspot.torigin/tx/ty/tz) also fully for CSS3D hotspots.
  • New: Improved fake 'Desktop-Mode' detection of the latest mobile browsers (iOS Safari, Android Chrome, Android Firefox).
  • New: Support the webvr_highrefreshrate and webvr_foveationlevel settings also for the WebXR API. Additionally there is a new webvr_ca_correction settings to optionally enable also a CA-Lens-Correction for WebXR API.
  • New: vtourskin.xml - add scene thumbnails only when thumburl is set and when skipthumb=true is not set. Can be used to skip certain scenes for being shown in the thumbnail-images-bar.
  • Change: The xml.scene variable now always contains the name of the loaded scene instead of the value the loadscene action was called with. Previously it could have been also the index of the scene.
  • Fix: The onstart event was not called when using scene.autoload.
  • Fix: The loadstate value and the blending start when loading a pano-video was wrong. The viewer already blended to the pano-video even before the video was actually loaded.
  • Fix: In 'follow' control mode clicking on layers could have initiated an unwanted movement in some cases.
  • Fix: The size of WebGL hotspots was wrong when using zoom=false and non-zero view.oz values.
  • Fix: Support detecting the iOS Desktop Mode also with iOS 14.
  • Fix: Spheretocube & Makepreview tool - support single-channel grayscale images as input.
  • Fix: krpano tools - on OSX 'kmem' folders were sometimes wrongly created.
  • Fix: vtourskin.xml - the skin_hotspotstyle and skin_tooltips styles use independent events by using addevent to allow adding own events.
  • Fix: vtourskin.xml - use isvalue() to allow using the value "0" for linkedscene.

krpano 1.20.7 (2020-05-26)

  • A Minor Bugfix- and Improvement-Release.
  • New: Avoid the creation of temporary files during the sphere-to-cube conversion on smaller input-images for a slightly faster pano building. Adjustable by the new converttocubemaxwidth_inmem setting.
  • New: <include> elements inside <scene> elements will be not resolved and loaded on xml loading, but later when loading the actual scene. This will speed up the startup-time when having a lot of scenes with <include> elements inside them.
  • New: Enable the Fullscreen Mode support for newer iPadOS versions.
  • New: Automatically internally downscale hotspot images that are too large for the current system. A warning will be shown in the krpano log when this happens. For manual control to avoid downscaling and directly loading a smaller image instead, there is the new device.maxtexturesize variable.
  • New: hotspot.borderhittest setting for optionally also using the border-line of polygonal hotspots for hit-testing.
  • New: Updated Postprocessing Demo: Popups with Background-Blur example - optionally add a close button to the popups and automatically close them when loading an other pano/scene.
  • Fix: WebVR - wrong (too small) 'stage' size when using the WebXR API and the latest Oculus Browser version (9.1). This browser version wasn't resizing the WebGL canvas to the requested pixelsize and this was affecting the multiresolution-level selection (too low-res view in some cases) and the size of non-distorted hotspots.
  • Fix: WebVR - rendering problems during pano-blending and when using post-processing in VR in the Oculus Browser when using the WebXR API.
  • Fix: WebVR - depthmap_navigation.xml - support VR controllers with thumbsticks when using the WebXR API.
  • Fix: WebVR - optionally support also the WebXR API in the Firefox Reality browser.
  • Fix: WebVR - support the WebXR-emulator-extension.
  • Fix: Catch and handle JS errors when trying to detect WebXR support in an iframe that doesn't allow WebXR usage.
  • Fix: Scrolling the krpano log was not possible on 'Notch'-iPhones with iOS 13.4.
  • Fix: Opening the contextmenu by long-taps wasn't working sometimes when using capturetouch=false on Android devices.
  • Fix: When using the setting safearea=false on children layers, their position was wrong.
  • Fix: When changing the display.safearea setting from test:... back to auto, the pano-canvas position wasn't correctly updated.
  • Fix: The onautorotateoneround event was using a wrong hlookat position when loading an new pano/scene without the KEEPVIEW flag within it.
  • Fix: The krpano Array getItem() function returns now null instead of the first array item when calling it with 0 or '' as parameter.
  • Fix: The loading state reported by the loadstate variable was wrong when using cubestrip or single-resolution sphere panos.
  • Fix: Makepano tool - The embedded sRGB ICC-color-profile was broken when using the NORMAL droplets.
  • Fix: Makepano tool - When using the NORMAL droplets with small images, then the output cube-images were sometimes wronlgy upscaled to the maxcubesize size.
  • Fix: Makepano tool - Generate spherical preview images instead of cubical ones (cubestrip) for sphereical panos.
  • Fix: Panotour Pro Update Package - remove several outdated device specific checks and workarounds from the Panotour Pro xml templates. This should fix some sound, video and web-content-hotspot problems on iOS devices.

krpano 1.20.6 (2020-04-15)

  • A Minor Bugfix-Release.
  • Fix: WebGL-rendered hotspots with very small scale values failed hit-testing (and didn't respond to events like clicking or hovering).
  • Fix: The onhover events added by addevent only worked when the element itself also had an onhover event.
  • Fix: The view.dir direction vectors are now also respecting the view.camroll rotation. This also affects the correct 3D location of 3D sounds when the view is rotated by the camroll setting, e.g. when using the gyro or when tilting the head left/right in VR.
  • Fix: The view.camroll rotation is also respected by the users panning controls and the viewing range-limits now.
  • Fix: The Oculus Browser will be always detected as 'Mobile VR' browser (by device.mobilevr or webvr.isvrbrowser) even when in Desktop Mode.
  • Fix: Allow the browsers default handling (panning, zooming) when using capturetouch=false.
  • Fix: Scrollarea Plugin - using overscroll=0.0 caused some unexpected behaviors.
  • Fix: WebVR Plugin - restore flat panos back to hfov=1.0 when exiting the VR mode.
  • Fix: The 64bit version of the krpano Testing Server requiered some MSVC runtime DLL files to be installed on the system. Now all is static linked and no external files are required.
  • Fix: Makepano tool - the EXIF GPS information couldn't be loaded from some images.
  • Fix: The Convert SPHERE CUBE Droplet didn't work when the input image contained embedded comments with '\#' text-parts.
  • Fix: vtour.xml - missing autotour setting.
  • Fix: vtourskin.xml - no gyro icon when starting with little-planet-intro.
  • Fix: vtourskin.xml - allow bouncinglimits controls for flat-panos.

krpano 1.20.5 (2020-03-05)

  • A Minor Bugfix- and Improvement-Release.
  • New: -license=### parameter for the krpano tools: directly use the given license code and don't register the license on the system (could be used on server systems).
  • New: -needlicense parameter for the krpano tools: the krpano tools will stop with exit/return code 1 (typically means error) when there is no valid license available.
  • New: Optional toggle parameter for the showlog() action.
  • New: autorotate.oneroundrange setting for using a custom 'range' for an autorotation-round.
  • Fix: The new follow pano-dragging control mode wasn't supported on touch-devices.
  • Fix: Fully support nested styles - a <style> element can have a style attribute too.
  • Fix: The content-dependent sub-division of depth-geometry data was only done for stl files, but missing for depth files.
  • Fix: The STL-to-DEPTH converter was using a fixed number precision, now the precision is based on the actual data.
  • Fix: vtourskin.xml - use the autotour autorotate events only when the skin_settings.autotour setting is actually enabled (to avoid interference with custom autorotate usages).
  • Fix: vtourskin.xml - using the littleplanetintro disables control.bouncinglimits setting.
  • Fix: Gyro/WebVR - in iOS 13.4 beta / Safari 13.1 the DeviceMotionEvent is broken and it is unclear if Apple will fix that. Therefore the DeviceOrientationEvent, which is working, will be automatically used as alternative instead on the related systems.
  • Fix: WebVR - when the setting mobilevr_sensor=0 was used, then entering the VR mode was working only on the first time.
  • Fix: Tab-characters in the krpano log were wrongly displayed as several '&nbsp;'.
  • Fix: Bingmaps Plugin - the mouse-wheel-zooming was wrongly centered.
  • Fix: Googlemaps Plugin - UI buttons from the Googlemaps API itself were not working/touchable on iOS.
  • Fix: Makepano tool - the EXIF parsing of the Ricoh Theta heading value failed in some cases.
  • Fix: Custom Tile-URLs example - the customParseTilePath() function wasn't adding the baseindex to the level-index. This was corrected previously in the viewer and now also the example was adjusted for that correction.

krpano 1.20.4 (2020-02-04)

  • A Minor Bugfix-Release.
  • Fix: Panos with a preview-pano-image in spherical format got a wrong maxpixelzoom limitation in some cases (a bug only in version 1.20.3).

  • Fix: Missing onpreviewcomplete event when using a preview-pano-image in spherical format together with non-tiled spherical pano-image.
  • Fix: The zero-padding of the level-index doesn't match between the xml and the generated tile-names when using more then 9 resolution levels and the new shorter xml syntax.
  • Fix: Avoid a unintentionally triggering of the log-opening touch-gesture on small or hidden viewer windows. Additionally the log-opening touch-gesture can be also disabled with the logkey=false setting.

  • A Minor Bugfix- and Improvement-Release.
  • New: Improved VR Support:
    • WebXR API support - additional to the WebVR API now also the WebXR API is supported. The usage of the WebXR API can be controlled by the new webxr embedding setting.
    • New webvr_highrefreshrate and webvr_foveationlevel performance tweaking settings for Oculus Go and Quest.

  • Change: vtourskin.xml - allow selecting the new follow control mode.
  • Change: Updated splitscreen example - allow also to view only the left or right images.
  • Fix: The 'krpano Tools' app was broken in the previous Linux versions.
  • Fix: Cubestrip preview-pano-images were not shown when using spherical or cylindrical multires-panos.
  • Fix: Spherical preview-pano-images were not supported.

  • Fix: The mouse/touch controls were partially not working in older IE11 versions when using touch-screens systems.
  • Fix: vtourskin.xml - the skin settings thumbs_opened=true and littleplanetintro=true were not working together, the thumbs were not shown after the intro.
  • Fix: When using custom levelsizes for the multires tile generation, the tile-index zero-padding of the tile-filenames was depending on the size of the input image and not on the custom levelsizes.
  • Fix: When using custom levelsizes for the multires tile generation, the level order was wrongly inverted.
  • Fix: Soundinterface Plugin - update to howler.js v2.1.3, that fixes 3D sounds in Chrome when using the panningmodel settings 'equalpower' or 'HRTF'.
  • Fix: Soundinterface Plugin - accessing sound[name].position wasn't working correctly.
  • Fix: Soundinterface Plugin - getting the value of sound[name].volume wasn't correct until the sound has been loaded.
  • Fix: Soundinterface Plugin - getting the value of sound[name].muted was wrong.
  • Fix: Soundinterface Plugin - the initial sound volume could be wrong in some cases.
  • Fix: The view.rx / view.ry settings were not used on CSS3D-rendered hotspots and non-distorted WebGL-rendered hotspots got wrongly distorted.

krpano 1.20 (2019-09-02)

  • New version number 1.20, no 'pre-release' / 'pr' state anymore.
  • The previous krpano-license and the krpano-maps-plugin-license were merged into one new single license. Additionally the new license offers also new features. Upgrading is possible here. Old licenses still fully work, but only without the new features.
  • New support for Multi-Resolution spherical and cylindrical panos (with any field-of-view, 360-around or partial-panos). Optimized for image-quality and rendering-performance.
    Especially very suitable for very large panos (Gigapixel and up) to avoid the need to convert to cube and for partial-panos.
  • New support for Depthmaps for adding 3D-depth to panoramic images. Allows 3D-stereo-depth without the need for stereo-images, post-perspective changes / 3D-movements, 3D-transitions between panos. Easy to use tools for creating the depthmaps are also available.
  • Much improved VR-Support: 6DoF positional-tracking, VR-controllers, improved devices support, faster Cardboard rendering. All fully customizable.
  • Polygonal hotspots rendering via WebGL: stereo and VR-support, faster rendering.
  • Improved cross-browser / cross-device mouse-wheel and touch-pad support - get the same zoom-amount and zoom-speed on all systems.
  • HTTPS support for the krpano Testing Server.
  • Many device- and browser-support updates.
  • New and slightly updated and restructured web design.
  • The download packages include now also a full offline documentation.
  • Only 64-bit versions for Windows by default. Technically 32-bit versions would be still easily possible, but normally there should be no need for them anymore. But if there is a need, then on request it would be still possible to provide 32-bit versions.
  • On Mac OSX all applications are now also available as 64-bit version.
  • All Windows executables are now code-signed.

embedpano (docu)

  • Change: The mobilescale setting is 1.0 by default now.
  • Change: The WebGL stencil and depth settings are enabled by default now. They are requiered for correct depthmap- and polygonal-hotspot rendering support.
  • Change: The WebGL antialias setting is not-set/undefined by default now. In this case the viewer tries to automatically decides which setting would be the best for the best performance on the current system.
  • Change: Do the local-file-access tests on the given xml file (instead of on the html file) when there is one. When there is no xml file set at startup, check inside the viewer the first loaded xml file for local-file-access problems and report back to the embedding script.
  • Fix: When using localfallback=none skip the local-file-access test.

krpano Viewer

  • New: Support for multi-resolution spherical and cylindrical pano-images in HTML5 (requires WebGL support from the browser).
