rendering - 3D user interface

This module provides a render pipeline system featuring:

• Class Scene to gather the data to render
• Widget View that actually renders the scene
• The display protocol, that allows any object to define its Display subclass to be rendered in a scene.

The view is for window integration and user interaction. Scene is only to manage the objects to render . Almost all madcad data types can be rendered to scenes being converted into an appropriate subclass of Display. Since the conversion from madcad data types into display instance is automatically handled via the display protocol, you usually don’t need to deal with displays directly.

opengl_version

Minimum opengl version required by the rendering pipeline

Display protocol

A displayable is an object that implements the signature of Display.

Rendering system

Note

As the GPU native precision is f4 (float 32 bits), all the vector stuff regarding rendering is made using simple precision types: fvec3, fvec4, fmat3, fmat4, ... instead of the usual double precision vec3

overrides

Dictionary of callables used by Scene.display to override the display protocol method object.display(scene)

global_context

Shared open gl context, None if not yet initialized

Views classes

View projections and navigation
