Ok, it works now. Is there a reason why you used 1.8*12 instead of just the focal length? Does the 1.8 come from somewhere?
For calculating the half height of a sensor I used: wFX = 36 hFX = 24 dFX = sqrt(wFX**2 + hFX**2) alpha = asin(wFX/dFX) d = dFX*lens.CropFactor h = cos(alpha)*d sensorHalfHeight = h/2 This assumes 3:2 aspect ratio at the moment. ------------------------------------------------------------------------------ Put Bad Developers to Shame Dominate Development with Jenkins Continuous Integration Continuously Automate Build, Test & Deployment Start a new project now.
