Methods

bool intersects(const Circle& a, const Circle& b)

Description:

Checks intersection between two circles.

Parameters:

• a: First circle.
• b: Second circle.

Returns: True if circles intersect.

bool intersects(const Circle& c, const pixelroot32::core::Rect& r)

Description:

Checks intersection between a circle and a rectangle.

Parameters:

• c: The circle.
• r: The rectangle.

Returns: True if they intersect.

bool intersects(const Segment& s, const pixelroot32::core::Rect& r)

Description:

Checks intersection between a line segment and a rectangle.

Parameters:

• s: The line segment.
• r: The rectangle.

Returns: True if they intersect.

bool sweepCircleVsRect(const Circle& start, const Circle& end, const pixelroot32::core::Rect& rect, pixelroot32::math::Scalar& tHit)

Description:

Sweeps a circle against a rectangle to find time of impact.

Parameters:

• start: Circle start position.
• end: Circle end position.
• rect: The static rectangle.
• tHit: Reference to store the time of impact.

Returns: True if a hit occurs along the sweep path.
