Question 1

How to create an animated fly-through with rayshader?

Accepted Answer

Use render_movie() after setting up a 3D scene with plot_3d(). Script camera movements using render_camera() to define orbits or custom paths for MP4 or GIF output.

Question 2

rayshader vs ArcGIS for 3D mapping?

Accepted Answer

rayshader excels in programmatic, high-quality rendering within R for reproducible research and custom visuals. ArcGIS is better for comprehensive GIS workflows with extensive data management and GUI tools.

Question 3

How to add custom textures to terrain in rayshader?

Accepted Answer

Use create_texture() to programmatically generate textures with specified colors, or load external images in sphere_shade(). Built-in palettes like 'desert' and 'imhof1' are also available for quick styling.

Question 4

Can rayshader handle large elevation datasets efficiently?

Accepted Answer

Yes, but performance may suffer. Downscale data with resize_matrix() and enable multicore processing in functions like plot_gg() to improve speed, though high-quality rendering remains computationally heavy.

Question 5

How to export a 3D map for 3D printing?

Accepted Answer

Use the built-in STL export function; after creating a 3D scene, save it as an STL file for 3D printing, as mentioned in the overview for producing physical terrain models.

Question 6

Is rayshader compatible with R Shiny for interactive web apps?

Accepted Answer

Partially; you can render snapshots with render_snapshot() and display them in Shiny, but full interactive 3D views rely on rgl widgets, which may have browser compatibility issues and limited scalability.
