Tucano encapsulates many common OpenGL/GLSL features in C++ classes, saving a lot of coding and allowing the developer to concentrate on the core of the application and the Shader codes.

By keeping the code clean and compact, Tucano also renders the code less bug prone.

• easily create and use Textures, FBOs, Shader Programs, Textures, modern OpenGL buffers...

• common classes used in most applications, such as Mesh, Camera, Trackball, and much more

• automatic texture unit assignment when binding textures, no need to worry about keeping track of ids

• uniforms, textures, and attributes are linked with the shaders in a simple and transparent way (no need to manually set locations)

• wrapper for Eigen Geometry, e.g. directly pass an Eigen Matrix4f to a GLSL Shader mat4

• use it with Qt, Glut, Glfw, or any other window manager that supports OpenGL

• default widgets for Qt, e.g. with a few lines of code open a 3D viewer with a trackball to visualize a Mesh

• examples and a collection of common effects (Phong, Image filters, SSAO...)

Documentation is available at http://lcg-ufrj.github.io/tucano

Tucano has only two library dependencies (make sure you have a recent version of them):

• Eigen : http://eigen.tuxfamily.org/
• GLEW : http://glew.sourceforge.net/

Note that you need an OpenGL driver that supports at least version 4.3.

No need to compile Tucano, just include tucano.hpp in your project and be happy!

• use the TUCANODEBUG flag for debugging

Tucano comes with several examples and an Effects Collection.

Check out the [Samples](@ref examples) page for the examples and the [Effects](@ref effects) Collection.

Even though Tucano 0.1 is out, there are still some features that are not implemented, such as encapsulation of Tesselation Shaders, and some Buffer Objects types. Some examples are still missing, but will soon be included in Tucano. Documentation is nearly up-to-date, but not 100%, completion is underway.

Please help us improve Tucano using GitHub's Issue Tracker.

Tucano is maintained by the Computer Graphics Lab at UFRJ.
