I’ve been using ParaView for some years now, but there still are important issues that I never have been able to resolve. Now I’m writing a tutorial about my workflow in ParaView, and before publishing it I need to know if there is really no solution for it in ParaView, or if I’m missing important things.
Is it possible to use absolute value ranges? When I load a 3D model (e.g., .obj) into ParaView, and apply the “Elevation” filter, the “Color scale” will only be relative, from 0 to 1. However, the model has an actual absolute scale (in meters), which allow me to do measurements on the model. Is it possible to use the absolute scale of the model, so that my color scale goes from, e.g., 0 to 2 m?
Related to the first question: Is it possible to have absolute contour lines (i.e., contours separated by, e.g., 0.1 m)? Right now, I can only do relative contours (e.g., a fixed number of 20 contours which are then evenly spread over the whole z range).
Some elements, most importantly the axis grid (which can be activated in the Properties pane) and contour lines (from the Contour filter), do not scale with the resolution I enter in the “Save Screenshot” tool during image export. Instead, the lines and fonts stay at a fixed pixel size, and get (on the exported high-res images) incredibly small or nearly invisible. The color scale, on the other hand, scales perfectly including its fonts. The option “Scale fonts proportionally” has no effect for this problem. I know that at least for the contour lines it is possible to increase “line width” in the properties pane of the Contour filter. But if I increase line width too much (>5) there are severe rendering issues, as the individual points of the contours appear star-shaped.
Any comments/hints would be greatly appreciated!
Thank you very much!
