Render-able Annotation types - 2, 3, 4, 5...n point relationsI'd like to be able to use a node type that took point selections
across one or more other nodes (mesh etc.) and output a set of floating point values that described the relationships between the points. These relationships would at a minimum include distance, angle, normal and center. This data could then be used by special annotation nodes that used established CAD standards to represent the relationships numerically and diagrammatically. These annotations (and ideally all annotations) would be render-able. I have notices there is some code in the API to do some of this, is it an existing WIP? ------------------------------------------------------------------------------ Come build with us!

Taking a simple example, if you mean "make dimension lines a primitive type, and provide painters for them", that's what I've had in mind. > I have notices there is some code in the API to do some of this, is it > an existing WIP?

Yes, but split the data calculation from the representation because the data is handy for other tasks such as parametrics or animation. The code needs to be smart enough to handle sets of 1-n selected points across multiple nodes. 1 point could have XYZ absolute position and polar coordinates 2 points can have distance, center, vector, as well as the 1 point data for each point. 3 points has center, plus the data for three sets of two points. Then there are the calculation of angles for the combinations of all set of three points in the selected points and bounding rectangles and boxes. The idea being that there is a set of routines for calculating useful geometric data from sets of points and that data can be used by a set of nodes that present the data in appropriate ways. >> I have notices there is some code in the API to do some of this, is it >> an existing WIP? > > Not sure what you're referring to here ... I thought I saw some relevant routines for calculating some of required data. It was probably just part of something else like the physics stuff. ------------------------------------------------------------------------------ Come build with us!

Sure, with this model, you have a modifier that takes geometry as input, and produces geometry + dimension lines as output. As always, you can have as many different modifier types as you like.
