Default Visualizing in Paraview

Hello,

I'm fairly new at visualizing 3D data in Paraview and I want to ask a small question:

I have a 3D surface which I have imported of size 1300*600*300. When I want to move around the sample in the 3D-view, it resamples it using the LOD. But every time I release the mouse button or change parameters or it renders the surface. This is very annoying and time consuming since the rendering each time takes aroud one minute. Is there any way that you can always look at the resampled LOD-view and manually render the surface whenever you want (after you have found the right camera angle and changed all parameters).

thanks
Tomas

Greetings Tomas and welcome to the forum!

It should be as easy as going to the menu "Edit->Settings", then on the tree item "Render View" and play with the options available there

If that doesn't work as you wanted, then use the filters "Triangulate" + "Decimate", to trim down the number of objects (triangles) to be rendered to the minimum value you want. Then on the "Pipeline Browser" tree you can toogle between visible objects when you want to move/see the geometry.

Best regards,
Bruno

The second alternative sounds pretty much what I want to do. But I'm somehow not allowed to select the triangulate or decimate filters?

The imported surface is of type .inp

regards
Tomas

There must anyway be a way of aborting the PolyPaiterDataMapper when it renders?

Hi Tomas,

The abort button depends on what's being rendered, so not all types of filters can be stopped from rendering. I'm assuming of course that the abort button still works sometimes...

When Triangulate isn't available, try other filters to bring it back. Nothing like a bit of trial-and-error to learn about some of the available filters .
For example, when I apply "Tetrahedralize" to a "Cone" geometry source, it becomes an unstructured grid, so I can't "Decimate" nor "Triangulate". So I apply "Extract Surface" to "Tetrahedralize", so it then becomes a "Polygonal Mesh" (see in the Information tab) and now I can apply "Decimate" directly to the "Extract Surface"!

Best regards and good luck!
Bruno

hi foamers. i hope that you are well. i have one question about paraview?
how can i see inside of 3D geometry, i wanna eliminte boundaries and see inside of 3d Geometry that what happen inside it,( i didnt wana use slice or clip to see contour on a surface or etc... i am gonna see countour of inside 3D geometry.)
