Classes

-------

vector.h -- vector of three scalars, also used for colour

matrix.h -- matrix class, currently not used

quaternion.h -- quaternion class for camera rotation

container.h  -- container for shapes, base class for octree and kd-tree

octree.h -- Octree space subdivision structure for acceleration of ray-shape intersection search

kdtree.h  -- KdTree space subdivision structure

scene.h -- scene objects: Ray, Light, Camera and shapes

raytracer.h -- ray tracer class

common.h -- Float definition (float/double) and some helper functions

Container Usage

---------------

(Container|Octree|KdTree) top;

scene.setTop(top)  // top object in hierarchy

top.optimize()     // build optimization structure

Rework camera

-------------

Sampler - generate points in screen plane

Camera - transform point from sampler to a ray

New Classes?

------------

scene.h   -- Scene, ...

reader.h  -- Reader, WavefrontReader

wf = new WavefrontReader()

wf.setContainer(top)

wf.setTransform(monkey_pos_matrix)

wf.read("monkey.obj")

// more transform&reads

destroy wf

Scene scene -- container with shapes, a camera and lights

scene = new Scene()

scene.setCamera(new Camera(eye, u, v, p))

scene.addLight(new PointLight(pos, color))

rt.setScene(scene)

rt.render(w,h)
