scene_from_list {rayvertex}

Scene From List

Description

Fast generation of rayvertex scenes from a list of objects (much faster than calling add_shape() on each object individually to build the scene). This returns a ray_scene object that cdoes

Usage

scene_from_list(scene_list)

Arguments

scene_list

List containing rayvertex mesh objects.

Value

ray_scene containing mesh info.

Examples

if(run_documentation()) {
 #Build a scene out of cubes including 87 * 61 = 5307 objects
 scene = list()
 volcol = rainbow(103)
 counter = 1
 for(i in 1:nrow(volcano)) {
   for(j in 1:ncol(volcano)) {
     scene[[counter]] = cube_mesh(position = c(i,(volcano[i,j]-94),j), 
                                  material = material_list(diffuse = volcol[volcano[i,j]-92],
                                                           ambient = volcol[volcano[i,j]-92],
