Last week I had asked questions regarding virtual cliptextures, what are
they? No one responded, so I will try to clarify my question.
Two parameters for a cliptexture, effective levels and LOD Offset, can
be set during run time. Effective Levels can be set in the ct config
file. Reading through the man pages and how a cliptexture is loaded it
appears that for any texture larger than 32K by 32K the LOD Offset must
be set. The following is an example of sample values
IMAGE SIZE |Effective Levels |LOD Offset
32k x 32k 16 0
64k x 64k 16 1
128k x 128k 16 2
...
Has anyone created cliptextures larger than 32K? Before I go out and
create all of the imagery for a 128k x 128k, I would like to make sure
this works! I created an empty 64K and 128K ic files and set the LOD
Offset in my program. It does not die or even choke. Is this a
sufficient test to see if the cliptextures are virtual and the 128K ic
is being read?
Thanks for any help,
Scott Brabson
