How to map pointData in a DataDisplay using C++

[César]

How are you,

I am translating a scene from XML to C ++, but I am stuck trying to map a pointData to a DataDisplay using C ++.

Below is an example of what works for me in XML and what I have in C ++. Thanks!

XML

<DataDisplay pointData=”@../dist.distance” />

C++

DataDisplay::SPtr bed_data_DataDisplay = addNew<DataDisplay>(bed_data);

XML

<EvalPointsDistance name=”dist” object1=”@/mesh_bed/MS” object2=”@.” listening=”true” period=”0.05″ draw=”true” />

<Node name=”data”>
<DataDisplay pointData=”@../dist.distance” />
<OglColorMap colorScheme=”Blue to Red” />
<IdentityMapping input=”@../.” output=”@.”/>
</Node>

C++

valPointsDistance3::SPtr bed_EvalPointsDistance = addNew<EvalPointsDistance3>(bed);
bed_EvalPointsDistance->setName(“dist”);
bed_EvalPointsDistance->setPeriod(0.05);
bed_EvalPointsDistance->setPathToMS1(“@../mesh_bed/.”);
bed_EvalPointsDistance->setPathToMS2(“@.”);

Node::SPtr bed_data = bed->createChild(“data”);

DataDisplay::SPtr bed_data_DataDisplay = addNew<DataDisplay>(bed_data);

OglColorMap::SPtr bed_data_OglColorMap = addNew<OglColorMap>(bed_data);
bed_data_OglColorMap->f_colorScheme.beginEdit()->setSelectedItem(“Red to Blue”);

IdentityMapping3::SPtr bed_data_IdentityMapping = addNew<IdentityMapping3>(bed_data);
bed_data_IdentityMapping->setPathInputObject(“@../.”);
bed_data_IdentityMapping->setPathOutputObject(“@.”);

Hi @cesar-vargas

I guess you are having an error right? runtime or compilation one?
Could you share it with us please?

Hi Hugo.

Thank you for your response. Actually, I am not having an error, I am just figuring out how to implement the following XML in C++, especially this part

<DataDisplay pointData=”@../dist.distance” />

<EvalPointsDistance name=”dist” object1=”@/mesh_bed/MS” object2=”@.” listening=”true” period=”0.05″ draw=”true” />

<Node name=”data”>
<DataDisplay pointData=”@../dist.distance” />
<OglColorMap colorScheme=”Blue to Red” />
<IdentityMapping input=”@../.” output=”@.”/>
</Node>

This is what I have:

valPointsDistance3::SPtr bed_EvalPointsDistance = addNew<EvalPointsDistance3>(bed);
bed_EvalPointsDistance->setName(“dist”);
bed_EvalPointsDistance->setPeriod(0.05);
bed_EvalPointsDistance->setPathToMS1(“@../mesh_bed/.”);
bed_EvalPointsDistance->setPathToMS2(“@.”);

Node::SPtr bed_data = bed->createChild(“data”);

DataDisplay::SPtr bed_data_DataDisplay = addNew<DataDisplay>(bed_data);

OglColorMap::SPtr bed_data_OglColorMap = addNew<OglColorMap>(bed_data);
bed_data_OglColorMap->f_colorScheme.beginEdit()->setSelectedItem(“Red to Blue”);

IdentityMapping3::SPtr bed_data_IdentityMapping = addNew<IdentityMapping3>(bed_data);
bed_data_IdentityMapping->setPathInputObject(“@../.”);
bed_data_IdentityMapping->setPathOutputObject(“@.”);

Thank you so much!

Alright @cesar-vargas ! My bad I did not get your point.

Most of it looks correct, just for the OglColorMap I would rather write:

bed_data_OglColorMap->f_colorScheme.setValue("Red to Blue");

Else :+1:

Best
