void CameraOp::draw_handle ( ViewerContext * ctx )

overridevirtual

Draws a lovely camera, I think it is a Mitchell.

Reimplemented from DD::Image::AxisOp.

Reimplemented in DD::Image::LightOp, and DD::Image::ComplexLightOp.

bool CameraOp::projection_is_linear ( int mode ) const

virtual

Returns true if current projection mode can be described linearly. This only true for perspective and orthographic modes if no lens distortion in being done.

References LENS_ORTHOGRAPHIC, LENS_PERSPECTIVE, LENS_SPHERICAL, and LENS_UV.

Referenced by DD::Image::rTriangle::add_to_render().

CameraOp::LensFunc * CameraOp::lens_function ( int mode ) const

virtual

Returns the current lens function used to distort vertices during software rendering. Single VArray version returns a Vector4.

References LENS_ORTHOGRAPHIC, LENS_PERSPECTIVE, LENS_SPHERICAL, and LENS_UV.

CameraOp::LensNFunc * CameraOp::lensNfunction ( int mode ) const

virtual

Returns the current lens function used to distort vertices during software rendering. Array function version that accepts a pointer to an array of VArray structures and thier number.

References LENS_ORTHOGRAPHIC, LENS_PERSPECTIVE, LENS_SPHERICAL, and LENS_UV.

Referenced by DD::Image::Render::_validate().

void CameraOp::to_format	(	Matrix4 &	matrix,
		const Format *	format
	)

static

Multiply the passed matrix by the necessary transformation to put x=-1 at the left edge of the format, +1 at the right, and to center it vertically, and compensate for any pixel aspect. The output z and w are left unchanged.

Most Iops will need to do this using their output format to get the actual transformation from input space to output space. You would do this first, then multiply by the projection*local*parent.

References DD::Image::Format::pixel_aspect(), DD::Image::Box::r(), DD::Image::Matrix4::scale(), DD::Image::Box::t(), DD::Image::Matrix4::translate(), DD::Image::Box::w(), DD::Image::Box::x(), and DD::Image::Box::y().

void CameraOp::from_format	(	Matrix4 &	matrix,
		const Format *	format
	)

static

Opposite transformation of to_format(). Multiplies the passed matrix by a transformation that scales the input format to go from x = -1 to x = 1 and to center it vertically around y = 0, and to remove any pixel aspect ratio. You multiply by this matrix last.

The 3DCard iop scales further so the image covers a range so that if the camera lens and "taking lens" are equal the image fills the field of view.

References DD::Image::Format::pixel_aspect(), DD::Image::Box::r(), DD::Image::Matrix4::scale(), DD::Image::Box::t(), DD::Image::Matrix4::translate(), DD::Image::Box::w(), DD::Image::Box::x(), and DD::Image::Box::y().

Referenced by DD::Image::GeoOp::build_matrix_handles().

const Matrix4 & DD::Image::CameraOp::projection ( ) const

inline

Returns a transformation to an output image due to the camera lens. This will transform points at the left edge of the film to an x value of -1, and points at the right to an x value of +1. Vertically it will produce a square transform, ie for most film shapes the +/-1 value for y is outside the top or bottom of the rectangular frame.

The z output of this transformation is set to match the OpenGL near/far clipping planes at -1 and +1. These planes may be chosen by Nuke to make a nice display with OpenGL, and you should avoid having them have any effect on the output image. If you want the actual distance to an object from the camera, the w output of this transformation will give you that.

For most uses you want to multiply projection()*xform() and pass the result through to_format() to get the transformation from world space to output pixels.

Referenced by draw_handle(), and projection().

Matrix4 CameraOp::projection ( int mode ) const

virtual

Return camera projection matrix for a particular projection mode. It needs to be overridden if subclasses implement a different logic to calculate the projection matrix.

References far_, LENS_PERSPECTIVE, projection(), DD::Image::Matrix4::projection(), radians(), DD::Image::Matrix4::rotateZ(), DD::Image::Matrix4::scale(), DD::Image::Matrix4::translate(), win_roll_, win_scale_, and win_translate_.

CameraOp * CameraOp::default_camera ( )

static

Return a default camera that can be used when the there is no camera attached to your renderer. This camera is at the origin, looking along -z, and has a lens ratio focal_length/film_width of 1.
