i dont think that patch is correct ... the demo will break with that patch if you disable double precision correct ?

Do You test it? I do and have no problems. ;-)
createVertexBuffer(vertexDecl->getVertexSize(0), vertexData->vertexCount, ...) creates buffer for three float cells. When using Real *pVertex=... and double_precision were enabled "Read" changes to "double". As result operations *pVertex++ = x0;*pVertex++ = y0;*pVertex++ = z0; outs of buffer...

To do this patch I were analise other demos, which uses createVertexBuffer and works with double_precision... ;-)
