VEX evaluation is typically very efficient giving performance close to compiled C/C++ code. VEX is not an alternative to scripting, but rather a smaller, more efficient general purpose language for writing shaders and custom nodes. VEX is loosely based on the C language, but takes ideas from C++ as well as the RenderMan shading language. VEX is used in several places in Houdini such as rendering, compositing, particles, modeling and more.
