Rhino can create, edit, analyze, document, render, animate, and translate NURBS* curves, surfaces, and solids and polygon meshes. There are no limits on precision, complexity, degree, or size. 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 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. Priced like other Windows software. No maintenance fees.

V-Ray for Rhino is a powerful render engine, which provides high-quality, photorealistic rendering capabilities to Rhinoceros, a popular Windows-based NURBS modeler. V-Ray for Rhino works comfortably within the Rhino environment, which allows users to render directly from Rhino, rather than worry about timely exporting.
Rhino users in all fieldsfrom engineering and architecture to design and animationneed a robust ray-tracing engine that enables them to bring their ideas to life quickly, easily, and cost-effectively.

With V-Ray for Rhino, ASGVIS offers these visualization professionals a state-of-the-art solution that generates high-quality images of unparalleled realism. Developed with the Chaos Group, V-Ray for Rhino works with Robert McNeel & Associates Rhinoceros, which is one of the most popular Windows-based NURBS modeling tools available today.

T-Splines: A new type of modeling surface
T-Splines combines classic methods from NURBS and subds with unique timesaving tools of its own to allow modelers to work with models as a single surface instead of as patches.

With its focus on keeping the surface as simple as possible, T-Splines accommodates both simple and complex modeling projects, and excels at organic shapes. T-Splines is used in applications ranging from video games to high-end human anatomy to CAD shape deformation.

Why use T-Splines?
Add detail only where you need it
Create even the most complex shapes as a single, editable surface
Create natural edge flow and non-rectangular topology

Bongo brings professional animation into Rhino 3.0 or 4.0, using familiar keyframe tools found in most high-end animation packages.
Professional animation tools

Animate moving, scaling, and rotating Rhino objects without exporting. Objects and viewport animations are editable in the Rhino window using simple drag and drop. Modify your objects and motion data without losing valuable time changing between programs.

Easily preview your animations inside Rhino, in real time, in any shading mode by scrubbing the timeline or playing the animation. Then render straight to an animation file using any Rhino renderer including wireframe, openGL, render preview, render, TreeFrog, Flamingo, and Penguin.

Bongo is also great for demonstrating moving objects using real-time playback in the Rhino viewports – just drag the timeline around to show a client how your design works.

Penguin brings freehand sketching, watercolor painting, cartoon-like rendering and technical illustration to Rhino and AutoCAD.

What is Penguin?

Penguin is a conceptual, sketch and cartoon, non-photometric scan line renderer. With Penguin you can create stylized images of your models with an artistic look for enhanced graphic and visual appeal.

Penguin 2.0 for Rhino
Penguin 2.0 runs inside Rhino and has the same hardware requirements. Rhino with Penguin runs on ordinary Windows desktop and laptop computers.
Penguin works with Rhino 4.

Penguin 2.0 for AutoCAD
No special hardware is needed beyond what is required for AutoCAD.
Penguin 2.0 works with 3D models of AutoCAD 2004 to 2008, including AutoCAD Architecture and AutoCAD Mechanical.

RhinoCAM is a Rhinoceros plug-in that runs completely inside of Rhino. This plug-in is a general purpose machining program targeted at the general machinist. RhinoCAM 1.0 includes 2-1/2 axis, 3 Axis and hole making operations. It comes with hundreds of post-processors and additionally a post-processor generator to create user definable post-processors.
