Examples Version 1.20.9
Animated Hotspots
xml: anihotspots.xml
Image-based animated hotspots.
This example shows how to use image-strips / sprite-sheets
as animated hotspot images.
The images will be animated by dynamically changing the crop setting
(which 'cuts-out' a certain region of the image) by xml action scripting.
The do_crop_animation <action>
in this example has no dependencies and can be easily reused in own examples.
It supports vertical, horizontal and tiled image-strips and loops the images from left-top to right-bottom.
As parameters the pixel-size of one frame and the favored frame-rate need to be set.
Background Sound
xml: backgroundsound.xml
Play a sound as background music.
In this example the soundinterface plugin will be used
to extend krpano with support for sounds.
To automatically start and stop the background sound only for the current pano (e.g. when using several scenes)
the playback will be controlled by pano-local events.
Additionally a small button is included to pause and resume the sound.
Blending Demo
xml: blending-demo.xml
WebGL-Blending-Modes Demo
This is an example to demonstrate the possibilities of the new WebGL-based blending modes.
The different blending-modes are custom settings for the blend
parameter of the loadpano() / loadscene() actions.

xml: tour.xml •
depthmap_navigation.xml •
tour_edithelper.xml
Depthmap-Tour of the 'Little Temple of Abu Simbel'
A full-featured demo tour using depthmaps.
It demonstrates how to view a pano dynamically from new perspectives,
e.g. to show wall friezes undistorted.
Additionally the depthmaps allow nice 3D-transitions.
The tour offers automatic- and manually-generated hotspots for navigation.
The depthmaps were generated by the everpano 3D tool,
the tour itself manually designed and coded.
A little helper tool for finding 3D viewpoint and hotspot positions is also included.
Depthmap Demotour: Gravina Apartment
xml: main.xml •
main2.xml •
project3d.xml
Depthmap-Tour of the 'Gravina Apartment'
The whole tour was fully generated by the everpano 3D tool.
For navigation in the tour the everpano Navigator plugin is used.
That plugin allows easy navigating by automatically finding the pano next to the point where the used had clicked -
and when there is no pano near, a nice 3D-zooming-animation indicates that.
Here for more depthmap-testing the same tour also with fully free 3D-movement and pano-navigation by automatic-generated hotspots: Gravina Apartment - Example 2

Depthmap/Experimental: Textured 3D-Model
xml: test.xmlimage: texture.jpg
A very first experimental test of using a textured 3D-Model.
Instead of using one panoramic image and projecting it onto a 3D-Model or using a Depthmap-image,
here a special image/texture generated from several panoramic images is used.
This could be used in several ways, e.g. for better 'Dollhouse views', for nicer transitions, for a better walking around in 3D/VR.
Technically this example here is only a first test. There will be probably many changes and improvments in the next releases,
e.g. faster loading, multires-texture-loading, a dedicated xml syntax/usage API, maybe with keeping the 3D-Model always in memory
for quick/instand switching to it when needed (for dollhouse views or scene transitions), maybe some mixing/blending with a higher-resolution pano image.
The 3D-Model and the texture were generated with the PanoCamAdder Add-on for Blender.
More information about the texture generation.

The 'Little Planet' view itself is basically only a Stereographic Projection plus looking down.
In krpano a stereographic projection distortion can be enabled by setting the
view.distortion setting to 1.0.
And by animation (tweening) this setting and the viewing direction a nice Little Planet
transition animation can be created.
The default vtourskin.xml
skin already provides a predefined Little Planet Intro script. To enable it only change the
littleplanetintro setting in the tour.xml to true.
Loading Progress
xml: loading-progress-example.xml •

This example shows three possibility to visualize the pano image loading progress -
as image-based loop animation (an image-strip with a crop animation),
as loading bar (by changing the size of a layer element)
and as percent text.
It would be possible just to include one of the example xml files to add that kind of loading progress animation
to an own pano or tour.
