render_model: Render Molecule Model

In raymolecule: Parse and Render Molecular Structures in 3D

Render Molecule Model

Description

Automatically plots the molecule with a camera position and field of view that includes the full model. For more control over the scene, pass the scene to 'rayrender::render_scene()' or 'rayvertex::rasterize_scene()' and specify the camera position manually. Note: spheres and cylinders in the scene are used to automatically compute the field of view of the scene–if rendering with rayrender, adding additional sphere (e.g. with 'rayrender::generate_ground()') will change this calculation. Use 'rayrender::render_scene()' instead if this is a problem.

Usage

render_model(
  scene,
  fov = NULL,
  angle = c(0, 0, 0),
  order_rotation = c(1, 2, 3),
  lights = "top",
  lightintensity = 80,
  ...
)

Arguments

scene	'rayrender' scene of molecule model.
fov	Default 'NULL', automatically calculated. Camera field of view.
angle	Default 'c(0,0,0)'. Degrees to rotate the model around the X, Y, and Z axes. If this is a single number, it will be taken as the Y axis rotation.
order_rotation	Default 'c(1,2,3)'. What order to apply the rotations specified in 'angle'.
lights	Default 'top'. If 'none', removes all lights. If 'bottom', lights scene with light underneath model. If 'both', adds lights both above and below model. This can also be a matrix of light information generated with 'rayvertex'.
lightintensity	Default '80'. Light intensity for pathtraced scenes.
...	Other arguments to pass to 'rayrender::render_scene()' or 'rayvertex::rasterize_scene()'

Value

Rendered image

Examples

# Generate a scene with caffeine molecule with just the atoms

get_example_molecule("caffeine") %>%
  read_sdf() %>%
  generate_full_scene() %>%
  render_model(samples=256,sample_method="sobol_blue")

#Light the example from below as well
get_example_molecule("caffeine") %>%
  read_sdf() %>%
  generate_full_scene() %>%
  render_model(lights = "both", samples=256,sample_method="sobol_blue")

#Generate a scene with penicillin, increasing the number of samples and the width/height
#for a higher quality render.
get_example_molecule("penicillin") %>%
  read_sdf() %>%
  generate_full_scene() %>%
  render_model(lights = "both", samples=256, width=800, height=800,sample_method="sobol_blue")

#Render the scene with rayvertex and custom lights
get_example_molecule("penicillin") %>%
  read_sdf() %>%
  generate_full_scene(pathtrace=FALSE) %>%
  render_model(width=800, height=800,background="grey66",
               lights = rayvertex::directional_light(c(0.2,1,1)))

#Rotate the molecule 30 degrees around the y axis, and the 30 degrees around the z axis
get_example_molecule("penicillin") %>%
  read_sdf() %>%
  generate_full_scene() %>%
  render_model(lights = "both", samples=256, width=800, height=800,
               angle=c(0,30,30),sample_method="sobol_blue")



#Add a checkered plane underneath, using rayrender::add_object and rayrender::xz_rect().
#We also pass a value to `clamp_value` to minimize fireflies (bright spots).
library(rayrender)
get_example_molecule("skatole") %>%
  read_sdf() %>%

  add_object(xz_rect(xwidth=1000,zwidth=1000,y=-4,
                     material=diffuse(color="#330000",checkercolor="#770000"))) %>%
