Detailed Description

Abstract class for display of VRML models using OpenGL/Mesa.

A window-system specific subclass needs to redefine the pure virtual methods.

---

Constructor & Destructor Documentation

ViewerOpenGL (  Browser &    browser )  [explicit]

Construct a viewer for the specified Browser. Parameters: browser  the Browser.

---

Member Function Documentation

bool checkSensitive (  int    x, int    y, EventType    mouseEvent )  [protected]

Check for pickable objects.

void transform (  const VrmlMatrix &    mat )  [virtual]

Multiply the current modelview matrix by mat. Parameters: mat  a matrix. Implements Viewer.
