save_obj file output over 1GB

RussellGrayxd commented 4 years ago

Is there any way to reduce the file output of the save_obj function? I've tried reducing all parameters and they only make the model lower quality, but not lower file size.

The save_obj function saves exactly what you have on the screen--to make the size smaller, you have to reduce the size of the original height matrix. You can do this by using the reduce_matrix_size() function to reduce the resolution of the heightmap (while maintaining the full resolution hillshade by only reducing in the call the plot_3d())

library(rayshader)
#Reduce by a factor of 1/2
heightmap %>% 
  sphere_shade() %>%
  plot_3d(reduce_matrix_size(heightmap, 1/2))

Similarly, if you're using plot_gg(), pass the amount you want to decrease the resolution to the argument reduce_size and it will do the same:

library(ggplot2)
#Reduce by a factor of 1/2
ggmtcars = ggplot(mtcars) +
  geom_point(aes(x=mpg,y=disp,color=cyl),size=5)

plot_gg(ggmtcars, reduce_size=0.5)
