| | TLineSegment ()=default |
| | A line which state is unspecified.
|
| |
| | TLineSegment (const TVector3< T > &origin, const TVector3< T > &direction) |
| | A line extending form origin to the furthest point possible along direction.
|
| |
| | TLineSegment (const TVector3< T > &origin, const TVector3< T > &dir, T minT, T maxT) |
| | A line that covers the parametric range [minT, maxT).
|
| |
| TLineSegment & | flip () |
| | Point the line in opposite direction.
|
| |
| void | setMinT (T t) |
| | Set the parametric distance where the segment starts.
|
| |
| void | setMaxT (T t) |
| | Set the parametric distance where the segment ends.
|
| |
| void | setRange (T minT, T maxT) |
| | Set the parametric range where the segment extends. The range is [minT, maxT). This is equivalent to calling setMinT(T) and setMaxT(T) together.
|
| |
| void | setRange (const std::pair< T, T > &minMaxT) |
| | Same as setRange(T,T).
|
| |
| void | setOrigin (const TVector3< T > &pos) |
| | Set the origin of the line.
|
| |
| void | setDir (const TVector3< T > &dir) |
| | Set the direction vector of the line.

template<typename T>
class ph::math::TLineSegment< T >
Represents a line segment in space.
Points \( \overrightarrow{P} \) on a line are modeled using the equation
\[
\overrightarrow{P} = \overrightarrow{O} + t\overrightarrow{D}
\]
where \( \overrightarrow{O} \) is the line origin and \( \overrightarrow{D} \) is the line direction, and \( t \) is a parameter in \( [t_{min}, t_{max}) \). Note the direction vector of the line does not need to be normalized.
