npm i gl-cone3d
Creates a cone plot of a vector field.
-
params
is an object that has the following properties:-
positions
(Required) An array of positions determining the location of the cones, encoded as arrays -
vectors
(Required) An array of vectors for the vector field, encoded as arrays -
coneSize
Size of the cones, scaled so that the reference cone size for the maximum vector magnitude is 1 -
absoluteConeSize
Size of the cones, scaled so that the reference cone size for vector magnitude 1 is one grid unit. -
coneOffset
The position of the cone with regard to the cone location. Ranges from 0 to 1 where 0 puts the center of the cone base at the cone location, and 1 puts the tip at the cone location. -
colormap
Colormap for the cone plot.
-
Returns A cone plot object that can be passed to gl-mesh3d.
