|
||
<p>This article describes two new OpenSceneGraph cross-platform examples and the
|
||
change in handling dependencies.</p>
|
||
<p><strong>Examples of HTTP client and node selection</strong></p>
|
||
<p>Once we finished working on <a href="https://github.com/OGStudio/openscenegraph-cross-platform-examples/tree/master/04.RemoteDebugging">the remote debugging example</a> and
|
||
<a href="http://opengamestudio.org/example-driven-development.html">reported its completion</a>, we were surprised by the fact
|
||
that secure HTTP connection between a debugged application and debug broker
|
||
was only working in the web version of the example. Desktop and mobile versions
|
||
only worked with insecure HTTP.</p>
|
||
<p>Since current debug scheme has no authentication, insecure debugging over HTTP
|
||
doesn't really hurt. However, if we want to access resources located at popular
|
||
sites like GitHub and BitBucket, we have to support secure HTTP.</p>
|
||
<p>The need to support HTTPS on each platform spurred us to create
|
||
<a href="https://github.com/OGStudio/openscenegraph-cross-platform-examples/tree/master/03.HTTPClient">HTTP client example</a>. Turned out, each platform had its own
|
||
preferred way of doing secure HTTP:</p>
|
||
<ul>
|
||
<li>web (Emscripten) provides Fetch API</li>
|
||
<li>desktop is fine with Mongoose and OpenSSL</li>
|
||
<li>Android provides HttpUrlConnection in Java</li>
|
||
<li>iOS provides NSURLSession in Objective-C</li>
|
||
</ul>
|
||
<p>The need to support different languages on different platforms resulted
|
||
in the creation of so-called 'host-guest' pattern:</p>
|
||
<ul>
|
||
<li>guest (platform agnostic)<ul>
|
||
<li>provides networking representation</li>
|
||
<li>used by cross-platform C++ code</li>
|
||
</ul>
|
||
</li>
|
||
<li>host (specific platform)<ul>
|
||
<li>polls guest for pending requests</li>
|
||
<li>processes them</li>
|
||
<li>reports results back to the guest</li>
|
||
</ul>
|
||
</li>
|
||
</ul>
|
||
<p><a href="https://github.com/OGStudio/openscenegraph-cross-platform-examples/tree/master/05.NodeSelection">Node selection example</a> was straightforward and caused no troubles.</p>
|
||
<p><strong>The change in handling dependencies</strong></p>
|
||
<p>For over a year we had to deal with the following
|
||
<a href="http://forum.openscenegraph.org/viewtopic.php?t=17443">shortcomings</a> when building OpenSceneGraph across platforms
|
||
using conventional methods:</p>
|
||
<ul>
|
||
<li>macOS builds failing due to certain compile flags we use</li>
|
||
<li>hacking PNG plugin safety guards to have PNG support under Android</li>
|
||
<li>iOS simulator and device builds of the same example being in separate Xcode projects</li>
|
||
<li>OpenSceneGraph taking 20-30 minutes to build</li>
|
||
</ul>
|
||
<p>These shortcomings were slowing us down and complicating the development of
|
||
new examples. Upon hitting these problems ten more times this month we decided
|
||
it was time to solve them once and for all. Now OpenSceneGraph is built as part
|
||
of each example in 2-3 minutes, and there's no more dependency magic involved.
|
||
We took the same approach of building dependencies as part of each example to
|
||
other external libraries like Mongoose and libpng-android, too.</p>
|
||
<p>With these obstacles out of the way, we can now iterate faster. Just in time
|
||
for the next technical demonstration of Mahjong 2!</p>
|
||
<p>That's it for describing two new OpenSceneGraph cross-platform examples and
|
||
the change in handling dependencies.</p><p class="subheader">Category: <a href="http://opengamestudio.org/category/news.html">News</a>
