The concept of the uncanny valley is particularly relevant to [[virtual reality ]] because the 3D graphics which are a staple of virtual environments often exhibit the phenomena when life-like avatars or characters are used. While cinematic 3D renderings have largely progressed past the point of evoking revulsion, the computational constraints of rendering in real-time for virtual reality mandate less complex results, which makes it difficult to create samples that are sufficiently lifelike to move past the uncanny valley.
