Introduction
===============================================================================

Spark is a research shading language that aims to improve support for
separation of concerns in real-time shaders.

This package includes source code for the command-line Spark
compiler (sparkc) and runtime (Spark.dll and SparkCPP.dll), along with
example programs that can be used to compare Spark and HLSL shaders.

Prerequisites
===============================================================================

In order to run the included example binaries, you will need:

- Windows 7 or Vista
  - Spark-generated shaders use the Direct3D 11 interface
- Microsoft .NET Framework version 4.0

===============================================================================
Documentation
===============================================================================

An introduction to the Spark language and a reference to the Spark interface
for Direct3D 11 can be found in:
spark/docs/Spark User's Guide.pdf

License information for Spark can be found in license.txt.

===============================================================================
Building
===============================================================================

Information on how to build the Spark compiler, runtime or examples from
source can be found in the file building.txt.

===============================================================================
Running the Example Programs
===============================================================================

The example programs are two Direct3D 11 samples from the DirectX SDK:
BasicHLSL11 and PNTriangles11. These examples have been ported to
support Spark shaders in addition to HLSL.

To launch the examples, build Spark and use one of the executables:

spark/examples/Direct3D11/BasicHLSL11/bin/x86/Release/BasicHLSL11.exe
spark/examples/Direct3D11/CubeMapGS11/bin/x86/Release/CubeMapGS11.exe
spark/examples/Direct3D11/PNTriangles11/bin/x86/Release/PNTriangles11.exe

Upon running these executables you should see a typical DX SDK example
window. The "Use Spar(k)" checkbox may be used to switch between Spark
and HLSL shading.

More information on the examples can be found in spark/examples/about.txt.

===============================================================================
Using sparkc
===============================================================================

The command-line Spark compiler does not currently include any command-line
option processing, so it must be used in exactly the following way:

    sparkc -o <prefix> <file>

This will compile the file containing Spark code, emitting any diagnostic
messages (warnings, errors) to standard error. It will generate two
C++ files, <prefix>.h and <prefix>.cpp, which provide a wrapper interface
to the shader classes defined in the file. Any non-abstract shader
class in the file will also have shader bytecode and C++ submission
functions generated.

===============================================================================
Known Issues
===============================================================================

Known issues with the Spark compiler and runtime are detailed in the file
issues.txt.
