animate_objects: Animate Objects

Description

This function animates an object between two states. This animates objects separately from the transformations set in `group_objects()` and in the object transformations themselves. This creates motion blur, controlled by the shutter open/close options in `render_scene()`.

Usage

animate_objects(
  scene,
  start_time = 0,
  end_time = 1,
  start_pivot_point = c(0, 0, 0),
  start_position = c(0, 0, 0),
  start_angle = c(0, 0, 0),
  start_order_rotation = c(1, 2, 3),
  start_scale = c(1, 1, 1),
  start_axis_rotation = NA,
  end_pivot_point = c(0, 0, 0),
  end_position = c(0, 0, 0),
  end_angle = c(0, 0, 0),
  end_order_rotation = c(1, 2, 3),
  end_scale = c(1, 1, 1),
  end_axis_rotation = NA
)

Value

Tibble of animated object.

Arguments

scene

Tibble of pre-existing object locations.

start_time

Default `0`. Start time of movement.

end_time

Default `1`. End time of movement.

start_pivot_point

Default `c(0,0,0)`. The point about which to pivot, scale, and move the objects.

start_position

Default `c(0,0,0)`. Vector indicating where to offset the objects.

start_angle

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

start_order_rotation

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

start_scale

Default `c(1,1,1)`. Scaling factor for x, y, and z directions for all objects.

start_axis_rotation

Default `NA`. Provide an axis of rotation and a single angle (via `angle`) of rotation

end_pivot_point

Default `c(0,0,0)`. The point about which to pivot, scale, and move the group.

end_position

Default `c(0,0,0)`. Vector indicating where to offset the objects.

end_angle

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

end_order_rotation

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

end_scale

Default `c(1,1,1)`. Scaling factor for x, y, and z directions for all objects.

end_axis_rotation

Default `NA`. Provide an axis of rotation and a single angle (via `angle`) of rotation around that axis.
