| Summary | 0006881: Truncation of double precision to floating point when rendering. | ||||||||
| Description | When rendering double precision data of 7 digits or more (e.g. Northings) the renderer seems to internally convert the data to floating point. I am attaching two .vtp file which illustrate the problem. NavXYZSRealCoords.vtp has double precision data where the x-coordinate is 7 digits. When you plot this you will see a characteristic banding pattern on the lines indicating that the data is being subsampled to a lower precision when plotted. NavXYZSNear000.vtp is the same data rescaled so that it is close to zero in the x- and y- axes. Here the plot is what we would expect. You can display these in ParaView to see the effect. NavXYZSRealCoords.vtp Bounds: (xmin,xmax,ymin,ymax,zmin,zmax) = (6167887.194354,6167937.979982,229956.716889,229999.075954,-642.855049,-641.947788) Number of points: 74548 Scalar range: (0.008196,0.030176) NavXYZSNear000.vtp Bounds: (xmin,xmax,ymin,ymax,zmin,zmax) = (-69.882646,-19.097018,16.275889,58.634954,-13.864049,-12.956788) Number of points: 74548 Scalar range: (0.008196,0.030176) | ||||||||
