Methods

GrapheneFrustum (Handle = null)

Allocates a new #graphene_frustum_t structure. The contents of the returned structure are undefined.
- @p Handle is an optional native handle or wrapper whose handle to adopt; when the native constructor is called.
toNativeHandle (Source)

Normalizes a constructor argument into a raw pointer carrier. Accepts a raw NativeHandle, a raw NativeBuffer returned from fn.call(...), another generated wrapper exposing handle(), or null. Returns null when the argument carries no pointer.
- @p Source is the raw handle, raw buffer, wrapper, or null.
- @r A raw pointer carrier or null when no pointer is present.
getLib ()

Returns the opened native library for this generated wrapper.
- @r The opened native library.
handle ()

Returns the wrapped NativeHandle.
- @r The wrapped NativeHandle.
isNull ()

Returns true when the wrapped handle is null.
- @r A bool.
describe ()

Returns a small string for debugging generated wrappers.
- @r A string.
contains_point (object point)

Checks whether a point is inside the volume defined by the given #graphene_frustum_t.
- @p point is a #graphene_point3d_t.
- @r true if the point is inside the frustum.
equal (object b)

Checks whether the two given #graphene_frustum_t are equal.
- @p b is a #graphene_frustum_t.
- @r true if the given frustums are equal.
free ()

Frees the resources allocated by graphene_frustum_alloc().
- @r None.
get_planes ()

Retrieves the planes that define the given #graphene_frustum_t.
- @p planes is return location for an array of 6 #graphene_plane_t.
- @r None.
init (object p0, object p1, object p2, object p3, object p4, object p5)

Initializes the given #graphene_frustum_t using the provided clipping planes.
- @p p0 is a clipping plane.
- @p p1 is a clipping plane.
- @p p2 is a clipping plane.
- @p p3 is a clipping plane.
- @p p4 is a clipping plane.
- @p p5 is a clipping plane.
- @r the initialized frustum.
init_from_frustum (object src)

Initializes the given #graphene_frustum_t using the clipping planes of another #graphene_frustum_t.
- @p src is a #graphene_frustum_t.
- @r the initialized frustum.
init_from_matrix (object matrix)

Initializes a #graphene_frustum_t using the given @matrix.
- @p matrix is a #graphene_matrix_t.
- @r the initialized frustum.
intersects_box (object box)

Checks whether the given @box intersects a plane of a #graphene_frustum_t.
- @p box is a #graphene_box_t.
- @r true if the box intersects the frustum.
intersects_sphere (object sphere)

Checks whether the given @sphere intersects a plane of a #graphene_frustum_t.
- @p sphere is a #graphene_sphere_t.
- @r true if the sphere intersects the frustum.
