<br>
I have an integer volume dataset. I wonder if I convert it to other data type (float, for example), would rendering of the new float volume be different from that of the original integer volume in terms of speed and quality?</blockquote></div></div></div></div></blockquote><div><br></div><div>It will affect the speed (at least the first frame) and may affect some more if are close to the GPU memory. It may not affect the quality as much other than the fact that now you are dealing with floats vs ints. I am curious on why do you want to convert your int dataset into floats? </div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex"><div class="gmail_extra"><div><div class="h5"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex"> My second question is that if I scaled down the data by dividing a scalar during the conversion, would the rendering of new volume have poorer quality?
