- Added a vector of triangles (three vertex indices) to class Geometry. This is useful for later implementation of ray picking.
- Added method DrawableEntity::getTransformationMatrix().
- Added UNTESTED method Geometry::intersects(), which takes a origin point and a direction. This method computes the nearest intersection's distance between the ray with the given origin and direction, and the current Geometry instance.
- Added UNFINISHED event handler OpenGLCanvas::mousePressEvent( QMouseEvent* mousePressEvent ) for capturing user clicks for ray picking.
