Rhino英文全名为Rhinoceros，中文称之犀牛，于1998年8月正式上市，是美国Robert McNeel & Assoc开发的PC上强大的专业3D造型软件，Rhinoceros软件在早期发展原型代号就称为“Rhino”。它能轻易整合3DS MAX 与Softimage的模型功能部分，对要求精细、弹性与复杂的3D NURBS模型，有点石成金的效能。

Rhinoceros – Versatile 3D modeler. Rhinoceros can create, edit, analyze, document, render, animate, and translate NURBS* curves, surfaces, and solids, point clouds, and polygon meshes. There are no limits on complexity, degree, or size beyond those of your hardware.
Special features include:
Uninhibited free-form 3-D modeling tools like those found only in products costing 20 to 50 times more. Model any shape you can imagine.
Accuracy needed to design, prototype, engineer, analyze, and manufacture anything from an airplane to jewelry.
Compatibility with all your other design, drafting, CAM, engineering, analysis, rendering, animation, and illustration software.
Read and repair meshes and extremely challenging IGES files.
Accessible. So easy to learn and use that you can focus on design and visualization without being distracted by the software.
Fast, even on an ordinary laptop computer. No special hardware is needed.
Affordable. Ordinary hardware. Short learning curve. Affordable purchase price. No maintenance fees.
Compatibility: macOS 10.13 or later 64-bit
