HOMEWORK 3:
AUTOMATIC MODEL GENERATION
GENERATOR COMPONENTS
There are 4 components:
- NEIGHBORHOOD GENERATOR
--
input is a file of parameters for a neighborhood.
The default file name is "nbhd.param".
If you have several neighborhoods, we suggest the
name "nbhd0.param, nbhd1.param, etc".
--
this program generates three output files
(street.param, block.param, nbhd.details).
--
The street.param file is a list of blocks and
their parameters.
--
The block.param is
a list of street segments and street intersections
and their parameters.
- BLOCK GENERATOR
--
input is block.param file from neigbhorhood generator
--
output file is block.details, containing
detailed description of the blocks.
--
this output is NOT a sequence of
OpenGL commands!
--
rather, it should be in some higher level
language that is specially designed.
--
We suggest that you make a series of
function calls (which in turn calls openGL).
--
this detail commands will refer to
various texture maps. These texture
maps are defined in a file called
"block.tex".
- STREET GENERATOR
--
input is a street file from the neighborhood generator
--
output file is street.details, containing
a detail description of the streets
--
pavements are included in this generator
--
various street details, including street life!
--
as for block generator output, this
output is NOT a sequence of OpenGL commands,
but some abstract language (perhaps openGL function
calls)
--
the street.detail commands will refer to
various texture maps. These texture
maps are defined in a file called
"street.tex".
- INTEGRATOR GENERATOR
--
This program combines the details in the files
nbhd.details, street.details, block.details to
produce an image for any eye/camera specification.
--
You need to be able to combine several neighborhood
files together.
E.g., for 2 neighborhoods, you have the following
6 files:
nbhd1.details, street1.details, block1.details,
nbhd2.details, street2.details, block2.details.
--
Certain details needs to be filled in by the integrator.
