Brazil for Rhino
Professional Edition

	Product Design Brazil can help you visualize your designs in a wide range of styles from high-quality photorealistic renderings, to easy to understand line drawings and illustrations.  Flexible camera settings help achieve realism. Mix and match photorealistic and Illustrative rendering styles. Simulate a vast array of complex materials -- everything from hard reflective materials to soft, translucent plastics.
	Jewelry Design Brazil is the ideal renderer for the hard-surfaces and complex light interaction needed by jewelry designers.  Diffusion in materials along with HDRI lighting create brillance in gemstones. Realistic lighting through caustic photon reflections and refractions. Advanced camera features, like depth-of-field, help show scale and make your renderings look like photographs.
	Transportation Design Sharp rendering and multilevel materials allow Brazil to simulate the complex material finishes needed for planes, trains and automobiles. Simple to use HDRI lighting makes set-up a snap. Accurate reflections communicate surface contours. Accurate shadowing and flexibility in camera lenses help create a sense of scale in your images.
	Architecture Design Brazil's render engine has the performance and flexibility to render all forms of exteriors, interiors and landscaping. Global Illumination and industry standard IES photometric datasets from lighting manufacturers can be used. Sunlighting system allows for site specific daylighting studies. Sophisticated, realistic materials allow you to work equally well whether doing interiors or exteriors.

Feature List

Raytracing Materials

Brazil's render engine uses the raytracing method. Raytracing has the advantage of simulating the way photons actually behave; although raytracing is not limited to realistic solutions it delivers some of the most photorealistic images available on any platform available today.

Brazil's advanced raytrace engine simulates a wide range of effects due to Brazil's extensive material model:

• Reflection
• Refraction (transparency)
• Dispersion (prismatic rainbow effects)
• Sub-surface scattering (diffuse light transmitting materials such as wax or skin)
• Glossy reflections (blurry or brushed materials)

Along with the Brazil's materials, we are introducing a new interface to edit the materials that includes realtime preview and support of drag and drop material assignment.

Advanced lighting

Rhino supports point, spot, directional, linear, and rectangular light objects with simple properties such as color, hotspot, and shadow casting. Brazil adds about 100 more light properties. The number of light properties can be intimidating, but most of these settings are only needed in a few specific cases.

Brazil light features include:

• Decay (darkening of light as a function of distance to the source)
• Attenuation (amplification of brightness as a function of distance to the source)
• Focus control (rectangular, conical, cylindrical etc.)
• Projections (emitting a picture or procedural texture instead of a color)
• Exclusion lists (lights ignore specified objects in the scene)

Brazil will also display focal cones and attenuation spheres for selected lights in the viewport, so you can see the affects of your settings in real-time.

Toon and NPR

Brazil includes non-photoreal (NPR) effects such as toon shaders.

(Car)Toon shaders cooperate with photoreal shaders so you can mix glass, brushed metal and toon in a single scene without losing the ability to do indirect-illumination, depth-of-field or any other effect.

You can specify the behaviour of fills and inks including:

• Multi-level paint fills (discrete colors applied based on luminosity)
• Gooch type fills, (continuous gradient)

Depth of Field

Depth-of-field (DOF) simulates the imperfect focusing properties of physical lens-systems such as biological eyes and cameras. DOF adds a measure of realism to a rendering by blurring out-of-focus areas. It can also be used to "mask" areas of the scene such as distant surroundings

Procedural Textures

Brazil supports both bitmap and procedural textures. Bitmap textures use images (a grid of colored pixels). Procedural textures, on the other hand, are defined by a mathematical function. Procedural textures do not suffer from resolution or tiling problems, and it is easy to change their behavior. Procedural textures are simulated in the Rhino viewport to make adjustments easy.

Some Brazil built-in functions:

• Checker
• Dots
• Gradient
• Marble
• Noise
• Tile
• Wrinkled

Advanced definitions can be used to create other realistic materials such as wood and stone.

High Dynamic Range colors

Brazil is a high-dynamic-range (HDR) engine

With an HDR rendering engine, colors are not limited to the black~white range. Colors can be brighter than white and darker than black. "Brighter-than-white" colors are important even though the computer screen cannot display them, because colors in a rendering are often diluted by partial reflection or refraction.

Global Illumination

Global Illumination is a feature you will find in most modern rendering platforms including Brazil.

Global Illumination uses both direct and indirect illumination to generate a realistic image. Direct illumination is the process where light objects cast light onto objects creating bright areas on surfaces that face the light source, darker areas on surfaces that do not face the light source, and shadows when surfaces cannot "see" the light source directly due to some obstruction. After a surface has been lit directly, it emits photons and some of those photons are captured by other surfaces and some of those photons are finally caught by our eyes or a camera. The effect of indirect illumination is relatively small compared to that of direct illumination. Yet, it is very important to the "realistic" quality of the image.
