Constructor Details

Frustum

public Frustum(MemorySegment address)

Create a Frustum proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

Frustum

public Frustum(Arena arena)

Allocate a new Frustum.

Parameters:

arena - to control the memory allocation scope

Frustum

public Frustum()

Allocate a new Frustum. The memory is allocated with Arena.ofAuto().

Frustum

public Frustum(Plane[] planes,
 Arena arena)

Allocate a new Frustum with the fields set to the provided values.

Parameters:

planes - value for the field planes

arena - to control the memory allocation scope

Frustum

public Frustum(Plane[] planes)

Allocate a new Frustum with the fields set to the provided values. The memory is allocated with Arena.ofAuto().

Parameters:

planes - value for the field planes

Method Details

getType

public static Type getType()

Get the GType of the Frustum class

Returns:

the GType

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

readPlanes

public Plane[] readPlanes()

Read the value of the field planes.

Returns:

The value of the field planes

writePlanes

public void writePlanes(Plane[] planes,
 Arena _arena)

Write a value in the field planes.

Parameters:

planes - The new value for the field planes

_arena - to control the memory allocation scope

alloc

public static Frustum alloc()

Allocates a new graphene_frustum_t structure.

The contents of the returned structure are undefined.

Returns:

the newly allocated graphene_frustum_t structure. Use graphene_frustum_free() to free the resources allocated by this function.

containsPoint

Checks whether a point is inside the volume defined by the given graphene_frustum_t.

Parameters:

point - a graphene_point3d_t

Returns:

true if the point is inside the frustum

equal

public boolean equal(Frustum b)

Checks whether the two given graphene_frustum_t are equal.

Parameters:

b - a graphene_frustum_t

Returns:

true if the given frustums are equal

free

public void free()

Frees the resources allocated by graphene_frustum_alloc().

getPlanes

public void getPlanes(Plane[] planes)
