performance drop in empty directx window
|
I wrote a MFC-based application which display a toolbar and an empty black directx window.
If I execute it just after the PC booted, the performance is quite high and I achieve approximately 500 fps. After few times that I re-execute it, the perfo... |

region filling
|
Consider a closed contour, each segment in the contour is defined by two 3D end points, the contour can thus be expressed as an ordered list of vertices, and the first and the last coincide.

Virtual Texture Demo

it looks like an impressive work.
Probably I missed something and I was wondering: in which ways it is different from a clipmap?

performance drop in empty directx window
|
Thanks for your suggestion.
I am pretty sure it is not a system memory problem, I have measured it and it never goes beyond 12 MB. Furthermore I checked for memory leaks and it seems that everything is ok.
However it may be a gpu memory problem... |

DrawIndexedPrimitive fails

I still don't get it :(
I draw using
if FAILED(manager.GetDevice()->DrawIndexedPrimitive(D3DPT_TRIANGLELIST, 0, 0, params.nVertices, 0, nbPrimitives))
hr = E_FAIL;
where params is a data structure holding the number of vertices.

Hi Tano,

Alternatively, you may look in the exporters available for ogre3d; there are several of them working with 3ds max, for example this one:
