Functions
glm::vec3	detectCollision (CylinderCollider &a, Transform &aTransform, CylinderCollider &b, Transform &bTransform)
	Detect collision between two axis-aligned cylinder colliders, and return the mtv such that if the first cylinder is translated by the mtv, the two objects no longer collide.
std::pair< glm::vec3, std::vector< Collision > >	ellipsoidTriangleCollisions (std::shared_ptr< GameWorld > world, Entity entityEllipsoid, Transform &transform, EllipsoidCollider &ellipsoidCollider, RigidBody &rigidBody, glm::vec3 move)
	Handle collisions between a moving ellipsoid and triangles in the scene. By default, this does 100 translations before dropping further movement.
void	cylinderCylinderCollision (std::shared_ptr< GameWorld > world, float deltaTime, float time)
	Process all cylinder-cylinder collisions. If two cylinders penetrate, they move by half of the minimum translation vector away from each other if they are both dynamic. Otherwise, only the dynamic one move and moves by the full mtv, plus some epsilon. By default, this only resolve 100 collisions per call.

cylinderCylinderCollision()

void Saga::Systems::anonymous_namespace{collisionSystem.cpp}::cylinderCylinderCollision	(	std::shared_ptr< GameWorld >	world,
		float	deltaTime,
		float	time
	)

Process all cylinder-cylinder collisions. If two cylinders penetrate, they move by half of the minimum translation vector away from each other if they are both dynamic. Otherwise, only the dynamic one move and moves by the full mtv, plus some epsilon. By default, this only resolve 100 collisions per call.

Parameters

world
deltaTime
time	time ellapsed since the start of the program.

detectCollision()

glm::vec3 Saga::Systems::anonymous_namespace{collisionSystem.cpp}::detectCollision	(	CylinderCollider &	a,
		Transform &	aTransform,
		CylinderCollider &	b,
		Transform &	bTransform
	)

Detect collision between two axis-aligned cylinder colliders, and return the mtv such that if the first cylinder is translated by the mtv, the two objects no longer collide.

Parameters

a	the first cylinder collider.
aTransform	the first cylinder transform, used to position the cylinder in space.
b	the second cylinder collider.
bTransform	the second cylinder transform, used to position the cylinder in space.

Returns

glm::vec3 zero if the two cylinders are not colliding. Otherwise the mtv.

ellipsoidTriangleCollisions()

std::pair< glm::vec3, std::vector< Collision > > Saga::Systems::anonymous_namespace{collisionSystem.cpp}::ellipsoidTriangleCollisions	(	std::shared_ptr< GameWorld >	world,
		Entity	entityEllipsoid,
		Transform &	transform,
		EllipsoidCollider &	ellipsoidCollider,
		RigidBody &	rigidBody,
		glm::vec3	move
	)

Handle collisions between a moving ellipsoid and triangles in the scene. By default, this does 100 translations before dropping further movement.

Parameters

world
entityEllipsoid	entity the ellipsoid is attached to.
transform	the entity's transform.
ellipsoidCollider	the entity's ellipsoid collider.
rigidBody	the entity's rigid body.
deltaTime	time since last update call, in seconds.

Returns

std::pair<glm::vec3, std::vector<Collision>> pair containing the ending position of the ellipsoid, as well as a list of all collisions that the ellipsoid triggered while moving.
