About Stream Tracer With Custom Source and Particle Tracer Filters

[Oracle_0 (Ravindra)]

Hi,

How do I set parameters such as Step-Size and Integrator-type for these filters? I can’t see any option in the properties panel.

I can't find an option/parameter/control in a dialog, or tab (such as the Properties tab)

Make sure to enable the advanced option by clicking on the gear icon: [2020-05-24-111301_31x30_scrot]

I tried doing it. Unfortunately, I can’t see where I can set Integrator-type like RK2 or RK4 and Step-Size. I have uploaded screenshots.

This is the ParticleTracer whic does not have these parameters exposed.

The StreamTracerWithCustomSource have them.

Oh, okay. Is there a way to set those parameters for ParticleTracer?
Also, what are default values of those parameters? Like is integrator RK2 or RK4?

@Oracle_0

Is there a way to set those parameters for ParticleTracer?

IntegratorType can be exposed with a custom XML plugin.

StepSize doesnt seems to be exposable, there is not C++ API for it as far as I can see.

what are default values of those parameters? Like is integrator RK2 or RK4?

RK4 is the default
IntegrationStep is 0.5

By the way these should be fixed in VTK/ParaView source code, it pretty simple to add there.
