hi, i’m currently using transformfeedback to capture some data from the geometryshader
the geometryshader doesnt create each invocation the same amount of primitives (points)
how can i query the amount of data that’s been captured ?

glBeginQuery(GL_TRANSFORM_FEEDBACK_PRIMITIVES_WRITTEN)
More explicitly, you wrap your use of feedback in a query object. A GL_TRANSFORM_FEEDBACK_PRIMITIVES_WRITTEN query will store the number of primitives generated by any feedback operation within the query’s scope.
ok, thanks, it works
