Introduction

Features

Raytracing

Brazil's render engine uses the raytracing method (as opposed to scanline or hardware renderers). Raytracing has the advantage of simulating the way photons actually behave; although raytracing is not limited to realistic solutions.

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.

Toon and NPR

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

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.

High Dynamic Range colors

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

Global Illumination

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

System Requirements

• Brazil for Rhino requires Rhino 4.0 or greater.

Supplementary Information

Note:  Some users have found that Brazil Evaluation doesn't work on Windows XP and 32-bit Rhino.   The solution is to download and install this patch from Microsoft.
