BRL-CAD is a powerful cross-platform constructive solid geometry solid modeling system that includes an interactive geometry editor, ray-tracing for rendering amp; geometric analyses, network distributed framebuffer support, image & signal-processing tools.
 
BRL-CAD supports a wide variety of geometric representations, including an extensive set of traditional implicit "primitive shapes" (such as boxes, ellipsoids, cones, and tori) as well as explicit primitives made from collections of uniform B-spline surfaces, non-uniform rational B-spline (NURBS) surfaces, n-manifold geometry (NMG), and purely faceted polygonal mesh geometry. All geometric objects may be combined using boolean set-theoretic CSG operations such as union, intersection and difference.

jFreeChart is a widely used open source charting library. Its flexible design is easy to extend and targets both server-side and client-side applications. It supports many output types, including Swing components, image files (PNG and JPEG) and vector graphics file formats (including PDF, EPS and SVG). It may not provide real time charts, updating the dataset once per second is fine. Refreshing the chart less than a second will result in high cpu load. <A HREF="http://www.ujihara.jp/jbyjsharp/jfreechart/" target="_blank">jFreeChart.NET</A> - JFreeChart ported on .NET.

c3p0 is an easy-to-use library for making traditional JDBC drivers "enterprise-ready" by augmenting them with functionality defined by the jdbc3 spec and the optional extensions to jdbc2. It provides (DriverManager-based) JDBC drivers with JNDI-bindable DataSources, including DataSources that implement Connection and Statement Pooling, as described by the jdbc3 spec and jdbc2 std extension. A connection pool is used to minimize the number of connections opened between application and database. Statement pool stores a partially compiled version of a statement in order to increase performance.
