-
class
PtfxDatasetReader: public ParticleDatasetReader ParticleDatasetReader implementation for the PTFX binary particle format.

Public Functions
-
PtfxDatasetReader()
-
bool
open(const Str &filePath, Error *error = nullptr) override Opens a PTFX dataset from the given file path.
Note
The dataset opens in positions-only mode — no scalar field is auto-activated. After a successful open(), call setActiveScalarField() to enable scalar coloring. The available field names can be queried with header().scalarFieldNames.
Protected Functions
-
std::unique_ptr<FrameData>
readFrame(size_t frameIndex, const Str &activeScalar) override Reads a single PTFX frame at frameIndex and returns it as FrameData.
This method is called without holding mutex(). Member fields read here (m_pimpl members and constHeader().scalarFieldNames) are set once in open() and never modified while isReaderOpen() is true.
-
void
resetDerivedState() override Resets PTFX-specific state (called by base class close())
