FixGlbLinesPrimitives()

bool FixGlbLinesPrimitives

(

const wxString &

aFilePath

)

Fix LINES primitives in a GLB file that have odd index counts.

OCCT 7.9+ can emit glTF LINES primitives with odd index counts for degenerate BSpline edges. The glTF spec requires LINES (mode 1) to have an even number of indices since each pair defines one line segment. Blender and other strict importers reject files that violate this constraint.

This function reads the GLB, adjusts any offending accessor counts to be even, and rewrites the file in place.

Parameters

aFilePath

path to the GLB file to fix

Returns

true if the file was processed successfully (or needed no changes)
