AxisOp is the base class for all the 3D objects. It simply contains a transform matrix.
| void AxisOp::_validate | ( | bool | for_real | ) | [protected, virtual] |
Validate our parent axis first, then concatenate the local transform with that. If the resulting matrix has changed, update the inversion flag and XYZ vectors.
Reimplemented from DD::Image::Op.
Reimplemented in DD::Image::ComplexLightOp.
References imatrix(), DD::Image::Op::input0(), inversion_updated, localtransform_, DD::Image::LookAt::lookAt(), lookat_input(), matrix_, and DD::Image::Op::validate().
| bool AxisOp::test_input | ( | int | input, |
| Op * | op | ||
| ) | const [virtual] |
Only AxisOp and NULL work.
Reimplemented from DD::Image::Op.
| void AxisOp::build_handles | ( | ViewerContext * | ctx | ) | [virtual] |
This default version will always cause draw_handle() to be called when in 3D mode. Subclasses (ie the camera) should replace draw_handle with their own version to draw what they want.
Reimplemented from DD::Image::Op.
References DD::Image::Op::add_draw_handle(), DD::Image::Op::build_input_handles(), DD::Image::Op::build_knob_handles(), display3d_, DD::Image::ViewerContext::expand_bbox(), DD::Image::Op::input0(), DD::Image::ViewerContext::modelmatrix, DD::Image::Op::node_selected(), DD::Image::ViewerContext::transform_mode(), DD::Image::Op::validate(), DD::Image::VIEWER_2D, and DD::Image::ViewerContext::viewer_mode().
| void AxisOp::draw_handle | ( | ViewerContext * | ctx | ) | [virtual] |
Draws any geometry attached to this axis. Note that the Axis knob will draw the 3-arrow axis control in the center.
Reimplemented from DD::Image::Op.

| const Matrix4 & AxisOp::imatrix | ( | ) |
Return the inverse object matrix. If the inversion has been marked invalid, calculate it now, otherwise return the current one.
