SUMMARY: Is texture mapping supported by the Sun ZX graphics card?

I asked:

Only two replies on this one (Does this mean the ZX card is a great source
of revenue for Sun?). I'll include them in full - since they are both

AVS Support Said:

(Neither patch made any difference to my particular problem)

What I Am Going To Do

I'll call Sun and see what they say and also I will look into the option of
modifying the data so that it appears to be a true 3d data set (rather than
the secondary operation of mapping a texture onto a pre-calculated surface)
- as I am hoping this may be a work around. Any further late breaking news
welcome - I will re-summarize if needs be.
