Member Function Documentation

bool rPoint::add_to_render ( Scene *  scene, PrimitiveContext *  ptx  )

virtual

Adds the point to the render if it is beyond the near plane.

Apply perspective to the point.

Implements DD::Image::rPrimitive.

References DD::Image::Scene::add_clipped_render_primitive(), DD::Image::MatrixArray::matrix(), DD::Image::Matrix4::transform(), and DD::Image::VArray::w_normalize().

bool rPoint::intersect_scanline ( float  y, int &  X, int &  R, VArray &  out, VArray &  du, VArray &  dv  ) const

virtual

Intersect the point with a scanline. Return whether it was successful and the left and right intersection vertices.

Implements DD::Image::rPrimitive.

References DD::Image::Box3::f().

float rPoint::trace ( Scene *  scene )

virtual

Not implemented yet.

Implements DD::Image::rPrimitive.

float rPoint::distance ( float  x, float  y  ) const

virtual

Distance the given screen-space point is away from the object. Returns 0 or negative if inside the object.

Implements DD::Image::rPrimitive.

float rPoint::distance_squared ( float  x, float  y  ) const

virtual

Square of the distance to the nearest edge the object in screen-space. Returns 0 or negative if inside the object.

Implements DD::Image::rPrimitive.
