Requirements
Houdini tasks the Graphics Processing Unit (GPU) rather than the Central Processing Unit (CPU) which is not typical to most 3D apps. As a result, Houdini specifies the requirements as an ATI FirePro or an Nvidia Quadro graphics card which is more stringent than the requirements for most 3D software. Due to this difference in function from typical 3D software, the CPU requirements are far more open. In addition, Houdini also requires a 3 button mouse (scroll wheel optional) and recommends a Wacom tablet for painting tools. Houdini runs on Windows, Mac and Linux.
