Can anyone help?
I am trying to create a mesh3D plot in plotlyR using R studio but I am having problems with how to create a colour scale to my mesh.
I have a nice mesh plot using the code,
p <- plot_ly(
x = points[, 1], y = points[, 2], z = points[, 3],
i = faces[, 1]-1, j = faces[, 2]-1, k = faces[, 3]-1,
type = “mesh3d”,
facecolor = “red”,
intensity = intensity,
colorscale = “red”,
showscale = TRUE
I’m not very sure what face colour does, intensity does or colour scale does, but I want to map a colour scale onto the mesh based on a value called bi, that I have measured for each point (ie, each x = points[, 1], y = points[, 2], z = points[, 3] point has a value of bi assigned to it in my dataframe). And I want to scale the colour where
vert$colour[vert$bi<= 0.5] <- "red"
vert$colour[vert$bi> 0.5 & vert$bi<=1.5] <- "green"
vert$colour[vert$bi>= 1.5] <- “purple”
or similar in a blending contour fashion.
Any thoughts on how to plot this?
All help welcome
here is the plot if that helps
