Simplex3dMath 1.0 is out!

The 1.0 version of the math library is out and the API is now stable.
There may be some future additions and improvements, but the core API
will remain unchanged.

Head to the project page for more details.

Mercury Demo.

An alpha version of Simplex3dBuffer library has been released! It naturally extends the math library capabilities into processing large sets of numertical data.

With the help of buffer library the task of generating dynamic models becomes a breathe. Take a look at the Mercury demo below (requires OpenGL 2.0):

Setting -Xmx for Scala compiler in Netbeans.

After upgrading to a latest Scala nightly I was no longer able to compile one of my projects. Clean and build would result in either "java.lang.OutOfMemoryError: GC overhead limit exceeded" or "java.lang.OutOfMemoryError: Java heap space".
An extensive google search revealed no solutions. Finally, after looking at the some source code, I was able to track down an undocumented option for Scala compiler ant plugin that Netbeans is using. I am posting a quick solution below. Hopefully it will be useful for someone who has stumbled upon the same problem.


Setting -Xmx for Scala compiler in Netbeans v6.8 using Scala-kit v0.16.1:

1. In Netbeans, open the file view of your project (tab "Files").

2. Navigate to "{project_home}/nbproject" and open "build-impl.xml".

3. find the following line:
scalac addparams="-make:transitive -dependencyfile ${basedir}/${build.dir}/.scala_dependencies @{addparams}" deprecation="${scalac.deprecation}" destdir="@{destdir}" encoding="${source.encoding}" excludes="@{excludes}" extdirs="@{extdirs}" force="yes" fork="true" includes="@{includes}" sourcepath="@{sourcepath}" srcdir="@{srcdir}" target="jvm-${javac.target}" unchecked="${scalac.unchecked}"

4. Add jvmargs option with desired jvm options (in this case jvmargs="-Xmx1024m")
scalac addparams="-make:transitive -dependencyfile ${basedir}/${build.dir}/.scala_dependencies @{addparams}" deprecation="${scalac.deprecation}" destdir="@{destdir}" encoding="${source.encoding}" excludes="@{excludes}" extdirs="@{extdirs}" force="yes" fork="true" jvmargs="-Xmx1024m" includes="@{includes}" sourcepath="@{sourcepath}" srcdir="@{srcdir}" target="jvm-${javac.target}" unchecked="${scalac.unchecked}"

5. Done. Now you can clean and build your project without OutOfMemoryError.

Released Simplex3d Math beta3

The math library has been updated. Beta3 version fixes some bugs and many corner cases. Transformations have been completely redesigned for both performance and ease of use.

Most of the code has been unit tested, though there are still some constructors and math methods remaining.
