Wow, looks cool. What do I do?
Just click on the map (of Doom's episode 1, mission 1) below. A
request will be sent to our render server, and if everything goes
right, you will receive back a JPEG of the level rendered from that
point of view.
How does it work?
We've got a program running on one of our SGIs that has the geometric
information about E1M1 (extracted using wadtoiv, my Doom to Open Inventor
converter), including textures and polygons, stored in its
memory. When it receives a request from this page, it decides on a
camera height and angle using the following heuristic:
(This has the approximate effect of picking the longest viewing
distance from the given point of view, and is used mainly to prevent
the camera from pointing right at a wall.) Then it renders the scene
and sends it to your browser. The pictures are 640 by 480, with 16
million colors. All the textures are automatically smoothed. They
usually look at least slightly better than the graphics in
the game. :-)
Pick a position between the floor and the ceiling. If there is no
floor or ceiling, pick a point between the (known) highest and lowest
points in the level. The vertical camera rotation (about the x-axis)
is a function of the height of the camera.
Pick a random horizontal camera rotation (about the y-axis) between 0
and 45 degrees.
Shoot 8 rays into the world, starting at this random rotation, at 45
degree intervals. These rays stop at the first point intersected.
Pick the ray with the longest length as the viewing direction of the
camera. If no ray intersected the world (i.e. way off the map), use
the original random rotation.
The renderer can only handle one request at a time, and will ignore
other requests during processing. So far
requests have been made, and of
those requests were served successfully.
NOTE: server is down (likely permanently). Sorry.
