Transforms the input image by a 4x4 transformation matrix.

_validate() calls this when the output image is invisible or otherwise cannot be calculated. It deletes the tp object to indicate this.

For implementing motion blur, return the matrix at various times. Default version changes the knobs and calls validate(), but a subclass can replace this if there is a faster way.
References matrix(), DD::Image::Op::outputContext(), DD::Image::Op::setKnobsToContext(), and DD::Image::Op::validate().
|
protectedvirtual |
Since _validate is fetching out values of knobs at nearby times to do motionblurring, we have to hash those in here, otherwise changing the velocity of the curve without changing its value will not result in the hash changing.
Reimplemented from DD::Image::Op.

virtual |
_validate() will combine all adjacent Transform operators into a single one. When you call engine() it will skip the earlier operators, read from the input to the first one (concat_input()), and process by a concatenated transformation matrix (concat_matrix()).
Reimplemented from DD::Image::Iop.
References _motionblur, _shutter, DD::Image::IopInfo::black_outside(), DD::Image::ShutterControls::calcOffset(), DD::Image::IopInfoOwner::channels(), degenerate(), DD::Image::ShutterControls::getDuration(), DD::Image::Box::h(), DD::Image::IopInfoOwner::info(), DD::Image::IopInfoOwner::info_, DD::Image::Iop::input0(), DD::Image::Filter::interpolative(), matrix(), DD::Image::Box::merge(), DD::Image::Box::move(), DD::Image::Op::outputContext(), DD::Image::Box::pad(), DD::Image::Box::set(), DD::Image::Op::slowness(), DD::Image::IopInfoOwner::t(), updateConcat(), DD::Image::Op::validate(), DD::Image::IopInfoOwner::w(), DD::Image::Box::w(), DD::Image::Box::x(), DD::Image::Box::y(), DD::Image::IopInfo::ydirection(), and DD::Image::IopInfoOwner::ydirection().
void Transform::setclip | ( | const Box & | box | ) |
After _validate() is called a subclass can call this to force the Transform to clip the output to a rectangle and put black outside it. The rectangle is exactly 1 pixel inside the passed Box (ie the box includes the black edge). The info() is set to this box. This is used by Reformat.
References DD::Image::IopInfoOwner::info_, and DD::Image::Box::set().
|
virtual |
this needs calling whenever the input pointers change even if they are pointing to equivalent Ops, as the Transform keeps its own pointers to its inputs.
Reimplemented from DD::Image::Op.
References DD::Image::Iop::input(), DD::Image::Op::setInputsValid(), and updateConcat().

draw_handle() will draw the input texture map. We only want this to happen for the first operator, so that if the user has several open at once the texture is only drawn once.

Evaluate a Mitchell filter at position x. This can be used by Nuke to view the filter shapes.
Matrix4 * Transform::matrix | ( | ) |
This virtual function should return the matrix used. A subclass can call reset() and then scale, translate, etc to get the matrix wanted and then return Transform::matrix(). You can also skip doing anything and return Transform::matrix() if valid() is true, since you know the matrix has been calculated then.

bool Transform::transform | ( | double | x, |
double | y, | ||
double & | X, | ||
double & | Y, | ||
double & | Z | ||
) |
Transform an input uv position into an output xyw.
Returns false for w <= 0. Such a point is not visible and has no output x/y position. However this version makes a "guess" as to what direction visible pixels that are near uv are and returns very large values for x,y in that direction. This is useful for calculating resulting bounding boxes.
bool Transform::concat_transform | ( | double | x, |
double | y, | ||
double & | X, | ||
double & | Y, | ||
double & | Z | ||
) |
Same as transform() but it uses the concatenated matrix, thus transforming coordinates from concat_input(). This only works after validate() has been called.

Set the transformation to the identity.

Transform further by an arbitrary transformation matrix. Like OpenGL all transformation operations are done by post-multiply, so this transformation is applied in the object's space. For instance a rotate(1) followed by a translate(1,0) will move the center of the object along a diagonal line.

Set what filter to use. This is an index into a table presented to the user in the Nuke GUI. Index 0 is impulse, index 1 is our default filter (Cubic). Others are not defined and may change at any time.
Return the current filter type.
|
inline |
If true then any negative intermediate results are set to zero. This can improve the results from high-contrast images and filters with negative lobes if you know nothing in the input is negative, by deleting a lot of the ringing in black areas.
The default value is false.
|
inline |
If true the transform will act as though any data outside the incoming bounding box is black. It will also produce an alpha channel if there is none in the input.
If this is false, Transform will replicate the pixels outside the bounding box instead. This will prevent any antialiasing on the edge. This is used by the Reformat operator, and may be useful for tile or camera shake type operators.
The default value is true.

All transform operators default to a purpleish color.

After _validate() is done, this returns the transformation between the concat_input() and the output of this operator.
