Why Is the T Pose the Default Stance for Human Models in 3D Graphics? Why Not Use the Standard Anatomical Position?
In the realm of 3D graphics, the T pose serves as the standard default stance for human models. This position, with arms outstretched horizontally and legs apart, may seem unconventional compared to the anatomical position typically used in human anatomy texts. However, there are specific reasons why the T pose has become the industry norm.
Reasons for Using the T Pose:
- Ease of Animation: The T pose provides a clear and consistent starting point for animators. It allows them to easily rotate and move the limbs without encountering any obstructions or overlapping.
- Efficient Rigging: The T pose simplifies the process of "rigging," which involves connecting the bones and joints of a 3D model. It creates a standard base position from which the animations can be built.
- Compatibility: The T pose is widely supported by different 3D modeling software and engines, ensuring compatibility and easy transfer of models between projects.
Why Not Use the Anatomical Position?
While the anatomical position is commonly used for медицинские and educational purposes, it is less suitable for 3D graphics due to:
- Obstructions: The anatomical position has arms hanging by the sides, which can create obstructions during animation.
- Rigging Complexity: Rigging the anatomical position is more complex and time-consuming, as it involves creating additional joints to account for the bent arms.
- Standard Deviation: The anatomical position lacks the clear and consistent base pose provided by the T pose.
