Module Scene

module Scene: sig .. end

Provides basic scene graph functionality.

type render_context = float * float

render_context is (jitter_x, jittery_y), which is used for antialiasing. Most nodes will ignore this or pass it off to any child nodes. Implementations of Scene.camera should use these values to jitter the perspective slightly as described in the Red Book chapter on antialiasing with the accumulation buffer.

class virtual scene_node : object .. end

Interface to a node in the scene graph.

class virtual camera : object .. end

Interface defining a camera position.

val null_camera : camera

A camera at the origin facing along the negative Z axis.

class stationary_camera : object .. end

A basic camera;;; Warning! This code is untested!

class ['a] observer : object .. end

class ['a] subject : object .. end

class displacement : ?x:float -> ?y:float -> ?z:float -> child:< draw_scene : 'a; .. > -> unit -> object .. end

A node that displaces its child.

class virtual scaleable : object .. end

Interface to nodes that have a changeable float attribute.

class virtual scaleable_2d : object .. end

class scene_node_collection : object .. end

class ['a] affector : object .. end

val null_scene_node : scene_node
