Hi Performers,
I have written an utility to convert landscape elevation data into a
pageable ASD (using ASDGen) and from what I could tell, the landscape
although untextured seemed to be alright when viewed using ASDFly.
Furthermore, I have written an utility to mipmap huge image and split it
up a into tiles for use with the cliptexturing system of Performer. I
have checked these files using ClipFly by writing the necessary .ic and
.ct files and was quite astounded how well the cliptexture mapping
system works.
Now the big problem is how to combine the landscape model and the
cliptextures that are to be laid on top of it. As far as I could tell,
this is not possible using ASDFly, since you can only specify a pageable
ASD along with a single .rgb texture, but not with cliptextures.
Looking into the terrain.c source file of ASDFly, I saw that there are
two flags that are set, depending on the mode specified in the
configuration file (it is the first entry in the config file). The first
flag specifies usage of a pageable ASD, the second specifies usage of
cliptextures. My first attempt was to see, what happened if I enabled
both of these at the same time, but that of course didn't work -- else
it would probably already have been there.
I hope that I don't have to rewrite the utilities, because working with
such huge amounts of landscape data (600mb elevation data, 6gb
photographs) it is very convenient to treat them separately.
Any suggestions? Should I use other viewers than ASDFly?
Thanks in advance,
Jan Marguc
