Methods

GraphenePoint3D (Handle = null)

Allocates a #graphene_point3d_t structure.
- @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.
cross (object b)

Computes the cross product of the two given #graphene_point3d_t.
- @p b is a #graphene_point3d_t.
- @p res is return location for the cross product.
- @r None.
distance (object b)

Computes the distance between the two given #graphene_point3d_t.
- @p b is a #graphene_point3d_t.
- @p delta is return location for the distance components on the X, Y, and Z axis.
- @r the distance between two points.
dot (object b)

Computes the dot product of the two given #graphene_point3d_t.
- @p b is a #graphene_point3d_t.
- @r the value of the dot product.
equal (object b)

Checks whether two given points are equal.
- @p b is a #graphene_point3d_t.
- @r true if the points are equal.
free ()

Frees the resources allocated via graphene_point3d_alloc().
- @r None.
init (double x, double y, double z)

Initializes a #graphene_point3d_t with the given coordinates.
- @p x is the X coordinate of the point.
- @p y is the Y coordinate of the point.
- @p z is the Z coordinate of the point.
- @r the initialized #graphene_point3d_t.
init_from_point (object src)

Initializes a #graphene_point3d_t using the coordinates of another #graphene_point3d_t.
- @p src is a #graphene_point3d_t.
- @r the initialized point.
init_from_vec3 (object v)

Initializes a #graphene_point3d_t using the components of a #graphene_vec3_t.
- @p v is a #graphene_vec3_t.
- @r the initialized #graphene_point3d_t.
interpolate (object b, double factor)

Linearly interpolates each component of @a and @b using the provided
- @factor, and places the result in @res.
- @p b is a #graphene_point3d_t.
- @p factor is the interpolation factor.
- @p res is the return location for the interpolated #graphene_point3d_t.
- @r None.
length ()

Computes the length of the vector represented by the coordinates of the given #graphene_point3d_t.
- @r the length of the vector represented by the point.
near (object b, double epsilon)

Checks whether the two points are near each other, within an @epsilon factor.
- @p b is a #graphene_point3d_t.
- @p epsilon is fuzzyness factor.
- @r true if the points are near each other.
normalize ()

Computes the normalization of the vector represented by the coordinates of the given #graphene_point3d_t.
- @p res is return location for the normalized #graphene_point3d_t.
- @r None.
normalize_viewport (object viewport, double z_near, double z_far)

Normalizes the coordinates of a #graphene_point3d_t using the given viewport and clipping planes. The coordinates of the resulting #graphene_point3d_t will be in the [ -1, 1 ] range.
- @p viewport is a #graphene_rect_t representing a viewport.
- @p z_near is the coordinate of the near clipping plane, or 0 for the default near clipping plane.
- @p z_far is the coordinate of the far clipping plane, or 1 for the default far clipping plane.
- @p res is the return location for the normalized #graphene_point3d_t.
- @r None.
scale (double factor)

- @factor. ``
- @p factor is the scaling factor.
- @p res is return location for the scaled point.
- @r None.
to_vec3 ()
