fNormalJ has wrong value.

Post by kimpaul »

Hi,

I'm using RequestGroundInfoOnSimObject for get the SIMCONNECT_DATA_GROUND_INFO.

The class variables like fAlt, eSurfaceType, eSurfaceCondition has correct value.

But the fNormal value something doubtable, specially fNormalJ.

fNormalI, fNormalK value was changed range in 0.0 ~ 0.3.

only fNormalJ value was changed range in 0.95 ~ 1.0.

I think fNormalJ mean up vector like(0, 1, 0). So it has 1.0 value in runway. It is Good.

But In slope like hills, the value changed very small. I want get correct value.

Please help me for care of this problem.

Thank you!

Hello,

Can you provide a test case/location where you believe the SimConnect call is providing inaccurate normal information?

Thanks.

Thank you for reply.

The test case or location is not matter.

Because I never see that the fNormalJ has value of under 0.95.

Another variable like fNormalI, fNormalK has changed range in 0.0 ~ 0.3. It has 0.3 gap.

But fNormalJ's gap is only 0.05.

If my expecting is wrong you can talk to me.

Thank you!
