What is this BE_Velocity node doing?
What is this BE_Velocity node doing? Is it possible to calculate the speed of the vertices of a mesh whose topology is constantly changing?

Such as realflow grid maya no speed information, we can use this BE_Velocity node to calculate the realflow vertex speed?

thanks!!

Suggestion to resample
I recently encountered such problems when doing n hair. I'm n-constrained by the point before rebuilding the curve. However, after rebuildCurve is rebuilt, the position of the constrained point changes.

The advantage of this resample node is that it does not change the position and id of the previous point. This is good!

Yes, it's good.
However, I hope that after rebuilding, I can still keep the position of all the previous points and the id of the point.
rebuildCurve can not do this, it changes the position of the previous point and id, this is sometimes not what we want.

hi peter

The second suggestion is that the resample input geometry can be a curve. Now it can only be Mesh. If you can cv point of the curve resample, it will be more perfect!

Who can tell me where is wrong? Why can not get UV?
thank besha1!!! Thank you for helping me!

I understand what you mean, if this setPoints node in later versions can be achieved to create a new UV function, then it will be more perfect!

Now we can select all the points before using resample, then create the selection, and wait for the resample solution before selecting the components in the selection. But this is not very convenient. It is not program control.

hi peter

We hope that the resample node can output the added points and the previous points, respectively.

Sometimes we do something about the previous point, such as n constraints. When we use resample processing, hoping to distinguish between the previous point and increase the point. This will preserve the processing of previous points. For example, keep the same point constraints.


There is another suggestion that is not very important. Resample can enter the curve, it will be more perfect. Now, you can use the node of soup to let it process the curve. But if you can handle the curve directly, that would be better.

vdb conversion grid is not UV. I added in the middle of an automatic projection uv node. Then use the getPoints and setPoints nodes, but the final grid does not have any UV information

Can you upload a project file instance? vbd convert bifrost the grid to get the bifrost emitter generated by the UV.

Thanks besha1 !!!

Thank you for helping me!

Can you tell me what should i do?

I would like to pass the bifrost emitter created by the UV to the grid on the vdb transform.

Thanks besha1 !!!

Solver node bug and some suggestions
I believe that after you read my project documents, will understand what I mean.

Thank peter

I installed the latest version,

Important, every time soup is automatically loaded first. And then load vdb, which causes the soup menu to have no vdb menu. Then, I unloaded soup, reload soup, the menu has vdb, but the old version of the node, only the toolbox on the vdb menu node is the latest.

Will peter, how to do first to load vdb, and then in the loading soup?

Thanks peter

Solver node bug and some suggestions
In fact, we can break the time node, with the expression to achieve.
E.g,

if (frame% 20 <8) {inTime = frame;}


This can be done to play 20 times, which will calculate the iteration 8 times.

However, mel running faster than C + +, but also need to write code. If you can achieve the steps of the group node, I think, will be very good.

Thank Peter! !!
