I am working out the feasibility and effort required to do the following in
Performer (using Multigen models) :-
a) Create the effect of moving water (eg sea waves and water flow down
a dam). I suspect that calls may need to be made to progressively
modify the u and v vectors for textured polygons. Am I right? If not,
how would I go about doing this.
b) Develop a simulation program with objects (eg many vehicles) moving
about in pre-defined paths. What kind of function calls do I need to
use?
c) Develop a program to interactively change colours and textures of
polygons (eg change wall paper designs and colours for different
walls in a house). Again what would be the most appropriate approach
and calls?
d) This is the ambitious one. What should I be considering if I am to
write code to interface Performer applications to a remote relational
database (eg INFORMIX), such that when I bump into an object during
flythrough, the system would respond by, for example, identifying
the object that was bumped into. The sort of messages returned by the
application should include responses to queries to a database. Some
responses could include text or image data popping up in sub-windows.
I was thinking along the lines of using something related to the
intersection traversal.
Cheers
