<div dir="ltr">Looks like:<div><br><div>1) I was wrong, you don't need to scale and bias the input array into 0..1. The transfer function editor widget's piecewise range controls let you specify what the input domain extent.</div><div><br></div><div>2) You are correct that there isn't currently a way to get the radii to be > 1.0 when applying the transfer function. Without the transfer function, the point size control sets the radii for all points. With it the transfer function's output (which is defined to be 0..1) controls the radii of each point. Please file a bug report.</div><div><br></div><div>Notes: With Point Gaussian representation there is an extra "point gaussian radius" control that gets factored in. We could do that with ospray, or factor in the existing point size, or possible extend the transfer function editor widget to change the range extent to something other than 0..1.</div></div><div><br></div></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div>David E DeMarle<br>Kitware, Inc.<br>Principal Engineer<br>21 Corporate Drive<br>Clifton Park, NY 12065-8662<br>Phone: 518-881-4909</div></div></div></div></div></div>

In my Pgmable Source PolyData, I render Points and love the OSPRay-rendered spheres. However, is there any mechanism for (independently) scaling these, i.e., other than the fixed Point Size? Or is the only way to get scalar-value scaled spheres via the Glyph filter? If so, is it possible to control the resolution/triangulation of that glyph? Basically, I’m looking for ways of getting high-res spheres, but will also want to use vtkCutter on them later.<br>
