Maybe, but: 1) for test renders you could use a lower resolution mesh;
2) for animatins you could do the tesselation once for the animation instead
of for every frame; and 3) possibly after you do the tesselation you could
save the mesh to a temporary binary file (platform independence of this
binary is not necessary as it is only temporary and is intended for use only
on the system on which it was created) and re-load it later.
