problem reading .raw file

I'm going to move this over to GP&T (although it could belong in GP as well) as this doesn't seem to be anything specific to the DirectX API.

From the look of your screenshot you've probably got some offsets wrong - it seems the heights are just shifted/wrapped horizontally by a constant amount.

I'd get friendly with your debugger of choice and see whats going on. Putting assertions/breakpoints in, printing out debug information is always a good idea. Can also help to run with an 8x8 (or similar) heightmap so you've got a more manageable set of data to step-through in the debugger.

Without any code theres little else that anyone here can do [smile]

Thank you jolly. :)
But i still stuck into this, think perhaps present codes is better. :/

OH BRAVO!
Nice buddy!! >=)
I got it work right now.
Okay , i actually put a header that's because it told me to do so in the first time. silly of me , thanks anyway =)
