<p>
Parallel raytracer / renderer that demonstrates the use of parallel_for.
</p>
<p><i>
This example includes software developed by John E. Stone. See
<a href="#copyright">here</a> for copyright information.
</i></p>
<p>
This example is a 2-D raytracer/renderer that visually shows different parallel scheduling
methods and their resulting speedup. The code was parallelized by speculating
that each pixel could be rendered in parallel. The resulting parallel code was
then checked for correctness by using Intel&reg; Thread Checker, which
pointed out where synchronization was needed. Minimal synchronization was then
inserted into the parallel code. The resulting parallel code exhibits good speedup.

<dl>
<dt><b>serial</b>
<dd>Original sequential version.
<dt><b>tbb1d</b>
<dd>Parallel version that uses Intel&reg; Threading Building Blocks (Intel&reg; TBB) and blocked_range to parallelize
over tasks that are groups of scan-lines.
<ul>
<li>By default, this version uses one thread per available processor. To change this
default, set the TBB_NUM_THREADS environment variable to the desired number of threads before running.
<li>This version uses the preview feature: auto_range_partitioner. No grain size is provided to blocked_range.
The blocked_range class uses a default grain size of 1 when none is provided. However, the auto_range_partitioner
controls the amount of range splitting dynamically at runtime, resulting in sub-ranges of varying sizes.
</ul>
<dt><b>tbb</b>
<dd>Parallel version that uses Intel TBB and blocked_range2d to parallelize
over tasks that are rectangular sub-areas.
<ul>
<li>By default, this version uses one thread per available processor. To change this
default, set the TBB_NUM_THREADS environment variable to the desired number of threads before running.
<li>This version uses a reasonable task grain size by default. To change this default,
set the TBB_GRAINSIZE environment variable to the desired grain size before running.
The grain size corresponds to the number of pixels (in the X or Y direction, for a
rectangular sub-area) in each parallel task.

<p>General build directions can be found <a href="../../index.html">here</a>.</p>
<p>
For Windows* systems Microsoft* Visual Studio* projects are provided for each of the above example versions.
</p>
<p>
The Makefile supports the following build targets (in addition to the <a href="../../index.html">general</a> ones).
Here, &lt;<i>version</i>&gt; is one of the above versions of the example, i.e., {serial, tbb1d, tbb}.
</p>
<dl>
<dt><tt>make &lt;<i>version</i>&gt;[_debug]</tt>
<dd>Build and run a single version (release or debug).
Equivalent to 'make build_&lt;<i>version</i>&gt;[_debug] run_&lt;<i>version</i>&gt;'.
<dt><tt>make build_&lt;<i>version</i>&gt;[_debug]</tt>
<dd>Compile and link a single version (release or debug).
The resulting executable is left in the directory for the example.
<dt><tt>make run_&lt;<i>version</i>&gt;</tt>
<dd>Run a single version previously produced by one of the above commands.
<dt><tt>make [(above options or targets)] DATASET={820spheres, balls, balls3, lattice, model2,
teapot, trypsin4pti}</tt>
<dd>Build and run as above, but run with the specified data set.
<dt><tt>make [(above options or targets)] ARGS=-D</tt>
<dd>Build and run as above, but run with disabled run-time display updating for use in making performance measurements
<i>(strongly recommended when measuring performance or scalability; see note below)</i>.
<dt><tt>make [(above options or targets)] UI={con, gdi, d2d, x, mac}</tt>
<dd>Build and run as usual, but build with the specified GUI driver: console, GDI+*, Direct2D*, X11, or OpenGL*
(see the description of the <a href="../../common/index.html">common GUI code</a>
for more information on available graphics support).
For Linux* and macOS* systems, the best available driver is detected automatically by the Makefile.
For Windows* systems, UI=gdi is the default GUI driver; compiling with UI=d2d may offer superior
performance, but can only be used if the Microsoft* DirectX* SDK is installed on your system.
Use UI=con to build without the GUI for use in making performance measurements
<i>(strongly recommended when measuring performance or scalability; see note below)</i>.
<dt><tt>make [(above options or targets)] XARCH=x64</tt>
<dd>Build and run as above, but
also specify XARCH=x64 (or XARCH=AMD64 for older compilers) when building the example on Windows* as a 64-bit binary.
<dt><tt>make [(above options or targets)] DDLIB_DIR=&lt;<i>specify path to Direct Draw* SDK here</i>&gt;</tt>
<dd>If you experience ddraw.lib linking problems, specify the correct library directory via this option.
