ply_model: `ply` File Object

Description

Load an PLY file via a filepath. Note: light importance sampling currently not supported for this shape.

Usage

ply_model(
  filename,
  x = 0,
  y = 0,
  z = 0,
  scale_ply = 1,
  subdivision_levels = 1,
  recalculate_normals = FALSE,
  material = diffuse(),
  angle = c(0, 0, 0),
  order_rotation = c(1, 2, 3),
  flipped = FALSE,
  scale = c(1, 1, 1)
)

Value

Single row of a tibble describing the obj model in the scene.

Arguments

filename

Filename and path to the `ply` file. Can also be a `txt` file, if it's in the correct `ply` internally.

x

Default `0`. x-coordinate to offset the model.

y

Default `0`. y-coordinate to offset the model.

z

Default `0`. z-coordinate to offset the model.

scale_ply

Default `1`. Amount to scale the model. Use this to scale the object up or down on all axes, as it is more robust to numerical precision errors than the generic scale option.

subdivision_levels

Default `1`. Number of Loop subdivisions to be applied to the mesh.

recalculate_normals

Default `FALSE`. Whether to recalculate vertex normals based on the connecting face orientations. This can be used to compute normals for meshes lacking them or to calculate new normals after a displacement map has been applied to the mesh.

material

Default diffuse.The material, called from one of the material functions diffuse, metal, or dielectric.

angle

Default `c(0, 0, 0)`. Angle of rotation around the x, y, and z axes, applied in the order specified in `order_rotation`.

order_rotation

Default `c(1, 2, 3)`. The order to apply the rotations, referring to "x", "y", and "z".

flipped

Default `FALSE`. Whether to flip the normals.

scale

Default `c(1, 1, 1)`. Scale transformation in the x, y, and z directions. If this is a single value, number, the object will be scaled uniformly. Note: emissive objects may not currently function correctly when scaled.

Examples

#See the documentation for `obj_model()`--no example PLY models are included with this package,
#but the process of loading a model is the same (without support for vertex colors).
