# RTAnalyticSource

VTKEx/Java/Images/RTAnalyticSource

### Description

Example to Create an image for regression testing. vtkRTAnalyticSource object just produces images with pixel values determined by a MaximumGaussianXMagsin(XFreqx)sin(YFreqy)cos(ZFreqz) Values are float scalars on point data with name "RTData".

Other languages

See (Cxx)
