 Storing a 3D scene for
Hi Folks,
I am looking for some advice for creating a very basic 3D application -
this isn't a competitor to any other product like K-3D/Blender etc, its
just a case of me wanting to learn more so I can eventually help out
projects like K-3D.
The first thing I wanted to do was to show an empty 3D scene, so I
started thinking about how I would actually store the scene and was
after some advice on ways of doing this. My initial thought would be
to set up a 3D array of some sort containing data, but after thinking
about this I had a number of questions.
For example I am not sure how the resolution of the array would
correspond to the resolution of the final image, if I set up an array
of 640x480 to contain my data - how does this - am I correct in
thinking that if I had some sort of parser to parse my array and then
output a file based on an existing file specification, for example
POV-Ray or Renderman format then the final output would be decided by
the renderer rather than the modeller?
Another question is how do I know how large to make my array?
Is there a "standard" or common way for doing something like this? Can
anyone give me opinions on ways of doing this?
I know that there are open source application available where I can
look at the source code, but many of these applications contain so much
other code that its difficult to separate out the stuff I want from the
stuff I don't want, plus much of this code contains advanced features
that complicate things.
Thanks,
Andrew McCall
