This repo is a collection of tools for working with POPs. Some of these OPs are targeted at common operations - and others are focused on data manipulation. While you're welcome to download the repo itself, you can also just use the TOX files published in the release.
This COMP converts latitude and longitude coordinates into XYZ coords. The primary mechanic for using this COMP is to load a .csv file from dist that has a column for lat and lon which contains the latitude and longitude coordinates you'd like to convert. Alternatively, you can pass in a POP that has a vec2 attribute called latLng which contains those values e.g. vec2(lat, lon)
The assumed radius of the sphere the coordinates is projected onto has a unit value of 1.
This COMP is used to load an splat generated by apple's sharp model and represent the splats as a point cloud. While the .ply files produced work well for splat viewers, retrieving the color data for a generalized point cloud requires some additional color transformation. This transformation is achieved with a Math Mix POP, and this component is intended as a convenience to no need to remember that formula.
