HOMEWORK 3:
AUTOMATIC MODEL GENERATION
TEXTURES
This is actually a key element in our modeling.
We think of this as being constructed
as a library of textures, properly catalogued.
The program will invoke textures which will be
provided by the library. E.g., our block generator
may ask for a texture with these parameters:
facade=BROWNSTONE,
height=80,
width=40
and it may get some close match to this description.
Here are some categories (but clearly, subcategories
ought to be defined):
- building facades
- building top features
- grass texture
- trees
- flowers
- skylines
- road textures (tarmac, cobblestone)
- pavement textures
Note: skyline texture will be used when you look down a street
(e.g., looking west of 14th Street, you might want
to show New Jersey Skyline). You may initially
default this to the clear blue sky.
How you collect textures is up to you: scanning from
magazines or other photos is the easiest. Then you need
to use a standard image editor (XV, Photoshop, etc)
to manipulate these images to produce a file of the texture.
But if you want to use digital cameras
for this purpose, please speak to me.
