<div dir="ltr"><div><div><div><div><div>Hi, VTKers,<br><br></div>I have a question when I try to visualize a huge amount of data set. I am wondering if the following approach is achievable or not in VTK?<br><br></div>Say, I have a large multiblock data set. Among these blocks, there are coarse meshes and fine meshes. Say, from the coarsest to finest, I denote them as mesh = 2, 4, 8, 16, 32, etc. Instead of showing the whole data set at one time on render window, what I want to do is as follows:<br>
<br></div>From the very beginning, I just suppose all blocks are the coarsest, i.e., mesh = 2, so I treat the whole data set as coarsest mesh and show it on render window; then after this is done, I pick up those blocks whose mesh = 4 and show them on render window again, but not as another object, I want somehow update the previous renderer to make it seems the plot is keeping updating; then next step, showing those blocks whose mesh = 8, 16, 32, etc. In this way, on the render window, the plot keeps updating, from the coarsest to the finest.<br>
<br></div>I don't know if I can achieve this or not in VTK? If it can be done, please give me some advice and idea how to do it?<br></div>Thanks in advance for any help.<br><br>Chao<br></div>
