Using NvTriStrip library from Nvidia, http://www.nvidia.in/object/nvtristrip_library.html
I was trying to use NVTriStriper for creating triangle stripes from triangle indices. But, seems it does not work perfectly.
The following is the input indices,
PrimitiveGroup *pPrimitiveGroup = NULL;
uint16 NbGroups;
uint16 ind[] = {1, 2, 3, 1, 3, 4, 0, 1, 4, 5, 0, 4, 61, 0, 5, 60, 61, 5, 59, 60, 5, 59, 5, 6, 6, 58, 59, 57, 58, 6, 7, 57, 6, 56, 57, 7, 8, 56, 7, 21, 56, 8, 21, 8, 9, 9, 20, 21, 19, 20, 9, 18, 19, 9, 18, 9, 10, 18, 10, 17, 11, 17, 10, 16, 17, 11, 16, 11, 15, 15, 11, 12, 15, 12, 14, 14, 12, 13, 21, 22, 56, 22, 55, 56, 22, 54, 55, 23, 54, 22, 53, 54, 23, 53, 23, 24, 52, 53, 24, 36, 52, 24, 36, 24, 25, 35, 36, 25, 25, 26, 35, 27, 35, 26, 27, 34, 35, 34, 27, 33, 33, 27, 28, 32, 33, 28, 31, 32, 28, 28, 30, 31, 30, 28, 29, 51, 52, 36, 37, 51, 36, 37, 50, 51, 37, 49, 50, 37, 48, 49, 48, 37, 38, 48, 38, 47, 39, 47, 38, 47, 39, 46, 46, 39, 45, 45, 39, 40, 44, 45, 40, 44, 40, 41, 43, 44, 41, 43, 41, 42};
uint16 count=180;
GenerateStrips(ind, count, &pPrimitiveGroup, &NbGroups, true);
The output generated is,
NbGroups = 1
(*pPrimitiveGroup).numIndices = 101
And stripe indices as follows,
outputIndices={10, 10, 17, 11, 16, 11, 15, 12, 14, 13, 13, 54, 54, 54, 22, 55, 22, 56, 21, 8, 21, 9, 20, 9, 19, 9, 18, 10, 17, 17, 2, 2, 2, 3, 1, 4, 0, 5, 61, 5, 60, 5, 59, 6, 58, 6, 57, 7, 56, 8, 8, 24, 24, 24, 36, 25, 35, 26, 35, 27, 34, 27, 33, 28, 32, 28, 31, 28, 30, 29, 29, 42, 42, 43, 41, 44, 40, 45, 39, 46, 39, 47, 38, 48, 37, 37, 48, 48, 37, 49, 37, 50, 37, 51, 36, 52, 24, 53, 23, 54, 22}
Now, with this out as you can see, there are triangles with indices such as (56, 8, 8), this results in rendering lines and not triangles.
Anyone aware of such problems in NVTriStrip?
