ThreeDVMobject R6 Class

Base class for all 3D vector mobjects. Extends VMobject with:

• Shade/lighting metadata (ambient, diffuse, specular)

• Normal vectors for lighting calculations

• Depth sorting hints for the renderer

Super classes

manimR::MObject -> manimR::VMobject -> ThreeDVMobject

Public fields

shade

Whether to apply lighting

gloss

Specular shininess (0-1)

shadow

Shadow intensity (0-1)

ambient

Ambient light factor (0-1)

normal

Normal vector for flat surfaces
