Three-Dimensional Scenes

Scripting in Three Dimensions

JSL includes commands for scripting three-dimensional scenes derived from OpenGL. Although not a complete OpenGL® implementation, JSL’s 3-D scene commands enable complex, interactive plots to be constructed and viewed. The Surface Plot platform in JMP is built using JSL scene commands.
