Member Function Documentation

closestPoint()

Physics::Bounding::ContactInfo Physics::Bounding::AABB::closestPoint ( const glm::vec3 &  p ) const

overridevirtual

Finds the closest point on the collider surface to a given point.

Parameters

p	Query point in the same space as the collider

Returns

ContactInfo containing closest point, normal, and penetration depth

Note

If p is inside the collider, penetration will be positive

The normal always points away from the collider surface

Use Cases

• Collision resolution (finding separation vector)
• Distance queries
• Computing contact manifolds

contains()

bool Physics::Bounding::AABB::contains ( const glm::vec3 &  p ) const

overridevirtual

Tests if a point is inside the collider volume.

Parameters

p	Point to test, in the same coordinate space as this collider

Returns

true if point is inside or on the surface, false otherwise

Note

For box colliders, "inside" includes the surface (closed volume)

This test is typically performed in world space after transformation

getAABBMin()

glm::vec3 Physics::Bounding::AABB::getAABBMin ( ) const

inlineoverridevirtual

Gets the minimum, maximum corner of the axis-aligned bounding box (AABB) that contains this collider.

Returns

Minimum or Maximum corner of AABB in local space

Note

This is used for broad-phase collision detection and spatial partitioning

For simple colliders like AABB, this is just the min,max corner. For others, it may require computation.

getTransformed()

std::unique_ptr< Physics::Bounding::ICollider > Physics::Bounding::AABB::getTransformed ( const glm::mat4 &  modelMatrix ) const

overridevirtual

Creates a transformed copy of this collider in world space.

Applies a 4x4 transformation matrix to create a new collider instance representing this shape in world coordinates. This is used to transform local-space colliders to world space for collision testing.

Parameters

modelMatrix

Transformation matrix (typically from SceneObject) Encodes translation, rotation, and scale

Returns

Unique pointer to transformed collider (ownership transferred)

Note

The transformation extracts:

• Translation: modelMatrix[3].xyz
• Rotation: Extracted via glm::decompose
• Scale: Applied to half-extents/radius

Caller receives ownership via std::unique_ptr

Returns nullptr only if transformation fails (rare)

Implements Physics::Bounding::ICollider.

Here is the caller graph for this function:

intersectRay()

std::optional< float > Physics::Bounding::AABB::intersectRay ( const Math::Ray &  ray ) const

overridevirtual

Tests ray-collider intersection.

Parameters

ray	The ray to test against this collider

Returns

Distance along ray if intersection occurs, std::nullopt otherwise

Note

Negative distances may be rejected depending on implementation
