Python Demos

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

All demos render images and write the result to PNG file

named with same base name as the script.

Scene is constructed using classes imported from pyrit

Python module.

boxes.py

        512 cubes with reflections and refractions

        4x oversampling, two lights, octree

bunny.py

        glass bunny, ~70k polygons

        4x oversampling, two lights, kd-tree

car.py

        low poly car model, LWOB format

        9x oversampling, two lights, kd-tree

spheres_shadow.py

        three spheres, sharp shadows

        4x oversampling, two lights, kd-tree

spheres_ao.py

        three spheres, ambient occlussion

spheres_glass.py

        row of glass spheres

        4x oversampling, three lights, kd-tree

render_nff.py [input.nff] [output.png]

        renders nff files (http://tog.acm.org/resources/SPD/)

        reads stdin if no args given

triangles_*.py

        older examples using OBJ file format

C++ Demos

---------

Compiled interactive demos. Camera can move freely in the scene.

realtime.exe

        one hundred spheres with reflections

realtime_bunny.exe

        bunny model (it loads silently, so be patient)

spheres_shadow.exe

        "interactive" version of spheres_shadow.py

textures.exe

        demo of different texture mappings

Control keys:

        Up, Down, Left, Right   look around

        w/s                     forward, backward

        c                       print camera coordinates

        spheres_shadow demo supports also:

        r/t, f/g, v/b           move the light (-x/+x, -y/+y, -z/+z)

        z/x                     change camera focal length (-/+)
