r2vr

Compose and serve WebVR scenes using R.

Building on top of Mozilla's A-Frame Framework, a suite of objects representing A-Frame scenes, entities, and assets are provided that can be composed using a functional R interface.

Thanks to the power and versatility of A-Frame and WebVR, these scenes will be viewable on all major VR platforms/devices including smartphone platforms like Google Cardboard. There are also no 3D graphics related dependencies to install, since these are injected as javascript links into the WebVR scene and downloaded at run-time by viewers.

Installation

devtools::install_github("ACEMS/r2vr")

Hello WebVR

library(r2vr)

## Define a scene
box <- a_entity(.tag = "box", position = c(-1, 0.5, -3),
                rotaion = c(0, 45, 0), color = "#4CC3D9",
                shadow = "")

sphere <- a_entity(.tag = "sphere", position = c(0, 1.25, -5), 
                   radius = 1.25, color = "#EF2D5E",
                   shadow = "")
                   
cylinder <- a_entity(.tag = "cylinder", position = c(1, 0.75, -3),
                     radius = 0.5, height = 1.5, color = "#FFC65D",
                     shadow = "")
                     
plane <- a_entity(.tag = "plane", position = c(0, 0, -4), 
                  rotation = c(-90, 0, 0), width = 4,
                  height = 4, color = "#7BC8A4",
                  shadow = "")
                  
text <- a_label(text = "%>% This is not js %>%",
                position = c(0, 2.5, -2), color = "#F92CEF",
                font = "mozillavr")

sky <- a_entity(.tag = "sky", color = "#ECECEC")

hello_world_scene <- a_scene(.template = "empty",
                             .children = list(box, sphere, cylinder, plane, 
                             text, sky))
