I'd recommend using knitr and rglwidget.  For example, put this in 
example.Rmd:

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```

```{r}
options(rgl.useNULL = TRUE)
library(rgl)
library(rglwidget)
xyz <- matrix(rnorm(30), ncol = 3)
spheres3d(xyz, col = 1:10)
rglwidget()
```


and then in RStudio, click on "knit HTML".  If you don't use RStudio, 
you can run

rmarkdown::render("example.Rmd")

and then view the "example.html" file in your browser.
