<h2>A Bundled BIM Viewer</h2>
<p>xeokit V1.1 includes <a href="https://xeokit.github.io/xeokit-bim-viewer/">xeokit-bim-viewer</a>,
a source 2D/3D BIM viewer built on xeokit, that runs in the browser and can load models from your
file
system.</p>
<p>This viewer is developed with support from <a href="https://www.digital-building-industries.com/">Digital
building
Industries AG</a> and
<a href="https://www.openproject.org/">OpenProject GmbH</a>.</p>
<p>The viewer is integrated within <a href="https://www.openproject.org/openproject-bim-10-4/">OpenProject
BIM 10.4</a>, and can also be used as a stand-alone JavaScript
application. In combination with open source CLI model conversion tools, it represents a low-cost,
high-performance way to get your IFC models on the Web, that allows you the freedom to convert and host
your models on your own server or GitHub repository.</p>
<p>The viewer even has its own <a href="https://xeokit.github.io/xeokit-bim-viewer/docs/">JavaScript
programming API</a>, through which you can programmatically load models, control UI state etc., to help
integrate it into your website.</p>

<p>xeokit V1.1 adds a <a

a fast HTML tree view component that can navigate

is fully customizable using CSS.</p>

<h2>Scalable Ambient Obscurrance (SAO)</h2>
<p>xeokit V1.1 adds Scalable Ambient Obscurance (SAO), which approximates <a
href="https://en.wikipedia.org/wiki/Ambient_occlusion" target="_external">Ambient
Occlusion</a> in realtime. It darkens creases, cavities
and
surfaces that are close to each other, which tend to be occluded from ambient light and appear
darker.</p>
<p>SAO was developed with support from <a href="http://dstudio.be/" target="_external">D-Studio</a>.</p>
<p>The animated GIF below shows the effect as we repeatedly enable and disable SAO. When SAO is enabled, we
can
see darkening
in regions such as the corners, and the crevices between stairs. This increases the amount of detail we
can
see when ambient
light is high, or when objects have uniform colors across their surfaces. Run the example to experiment
with
the various
SAO configurations.</p>

<h2>Improved Camera Controls</h2>
<p>xeokit V1.1 includes several improvements to xeokit's <a
href="https://xeokit.github.io/xeokit-sdk/docs/class/src/viewer/scene/CameraControl/CameraControl.js~CameraControl.html">CameraControl</a> component.</p>
<p>One useful CameraControl improvement is camera speed that automatically scales to the distance to the object
in front. This technique allows us to move quckly across open spaces and slowly across confined spaces.</p>

<p>xeokit V1.1 includes a new version of its .XKT geometry format (V3), which fixes an accuracy
issue with IFC models positioned far from the World-space origin. The <a
href="https://xeokit.github.io/xeokit-sdk/docs/class/src/plugins/XKTLoaderPlugin/XKTLoaderPlugin.js~XKTLoaderPlugin.html">XKTLoaderPlugin</a>
and the <a href="https://github.com/xeokit/xeokit-gltf-to-xkt">xeokit-gltf-to-xkt</a> conversion tool
have both
been updated with this fix.</p>

<h2>More Tips for Converting IFC Models for xeokit</h2>
<p>The <a href="https://github.com/xeokit/xeokit-sdk/wiki/Creating-Files-for-Offline-BIM">Creating
Files for Offline BIM</a> tutorial now
includes more techniques for avoiding precision loss when converting IFC files for loading into xeokit.

<h2>What's Next?</h2>
<br>
<h4>Support for larger BIM models</h4>
<p>xeolabs continues to research the best ways to view huge IFC models on the Web. Geographically large IFC
models rely on double-precision coordinates, however graphics in Web browsers only supports
single precision. At xeolabs, we are developing enhancements to xeokit's XKT geometry format, used by <a
href="https://xeokit.github.io/xeokit-sdk/docs/class/src/plugins/XML3DLoaderPlugin/XML3DLoaderPlugin.js~XML3DLoaderPlugin.html">XML3DLoaderPlugin</a>,
that
will allow us to load such models into xeokit, without loss of precision.</p>
<br>
<h4>Improved measurements UX</h4>
<p>Also, to improve the usability of xeokit's measurement tools, such as <a
href="https://xeokit.github.io/xeokit-sdk/docs/class/src/plugins/DistanceMeasurementsPlugin/DistanceMeasurementsPlugin.js~DistanceMeasurementsPlugin.html"
target="_external">DistanceMeasurementsPlugin</a> and
<a href="https://xeokit.github.io/xeokit-sdk/docs/class/src/plugins/AngleMeasurementsPlugin/AngleMeasurementsPlugin.js~AngleMeasurementsPlugin.html"
target="_external">AngleMeasurementsPlugin</a>, future versions will introduce snap-to-vertex
interaction, where the mouse or
touch pointer
will
automatically snap to the nearest vertex.</p>
