Unigine::ShapeConvex Class

Header:#include <UniginePhysics.h>
Inherits:Shape

This class is used to create collision shape in the form of a convex hull.

ShapeConvex Class

Members


static ShapeConvexPtr create()

Constructor. Creates a new empty convex hull.

static ShapeConvexPtr create(const Ptr<Object> & object, int surface)

Constructor. Creates a convex hull for a given object surface.

Arguments

  • const Ptr<Object> & object - Object, which surface will be approximated.
  • int surface - Number of the surface to approximate with the convex hull.

static ShapeConvexPtr create(const Ptr<Body> & body, const Ptr<Object> & object, int surface)

Constructor. Creates a convex hull for a given object surface and adds it to a given body.

Arguments

  • const Ptr<Body> & body - Body, to which the convex hull will belong.
  • const Ptr<Object> & object - Object, which surface will be approximated.
  • int surface - Number of the surface to approximate with the convex hull.

Ptr<ShapeConvex> cast(const Ptr<Shape> & shape)

Arguments

  • const Ptr<Shape> & shape

int setObject(const Ptr<Object> & object, int surface, float error = 0.01)

Sets an object surface, for which the convex hull should be created.

Arguments

  • const Ptr<Object> & object - Object, which surface will be approximated.
  • int surface - Number of the surface to approximate with the convex hull. If -1 is passed to the function as a number of the surface then the convex hull is created for all the surfaces of the mesh.
    Notice
    For a dynamic mesh, the convex hull is not created for all the surfaces.
  • float error - Permissible error, which is used to create the convex hull. This is an optional parameter.

Return value

1 if the convex hull is created successfully; otherwise 0.
