from panda3d.core import BillboardEffect
- class BillboardEffect
Indicates that geometry at this node should automatically rotate to face the camera, or any other arbitrary node.
- get_axial_rotate() bool
Returns true if this billboard rotates only around the axis of the up vector, or false if it rotates freely in three dimensions.
- get_eye_relative() bool
Returns true if this billboard interprets the up vector relative to the camera, or false if it is relative to the world.
- get_fixed_depth() bool
Returns true if this billboard always appears at a fixed distance from the camera.
- get_look_at() NodePath
Returns the node this billboard will rotate to look towards. If this is empty, it means the billboard will rotate towards the current camera node, wherever that might be.
- get_look_at_point() LPoint3
Returns the point, relative to the
look_at()node, towards which the billboard will rotate. Normally this is (0, 0, 0).
- get_offset() float
Returns the distance toward the camera (or the look_at_point) the billboard is moved towards, after rotating. This can be used to ensure the billboard is not obscured by nearby geometry.
- is_off() bool
Returns true if the
BillboardEffectis an ‘off’
BillboardEffect, indicating that it does not enable billboarding. This kind of
BillboardEffectisn’t particularly useful and isn’t normally created or stored in the graph; it might be implicitly discovered as the result of a NodePath::get_rel_state().
- static make(up_vector: LVector3, eye_relative: bool, axial_rotate: bool, offset: float, look_at: NodePath, look_at_point: LPoint3, fixed_depth: bool) RenderEffect
Constructs a new
BillboardEffectobject with the indicated properties.
- static make_point_eye() RenderEffect
A convenience function to make a typical eye-relative point-rotating billboard.
