Push your simulations to new extremes with new maths/physics classes featuring double precision floating-point numbers.

可编程渲染管线（SRP）兼容性

Unity可编程渲染管线（SRP）是让您能够通过C#脚本控制渲染的一个功能。SRP是支撑通用渲染管线（URP）和高清渲染管线（HDRP）的底层技术。

描述

Vector3 and friends, but backed by doubles instead of floats.

This free library gives you new data types in Unity. They provide the same functionality as the Unity maths and physics libraries, but they are built using double precision floating-point numbers.

The classes are designed to be instantly familiar to Unity users. There are very few caveats or missing methods. The included classes and methods are fully listed with comprehensive documentation here.

Consider of course that doubling the precision will affect memory usage and performance. If there's something you think is missing, feel free to get in touch.

技术细节

Double precision implementation of the following Unity classes:

Mathf
Vector2
Vector3
Vector4
Quaternion
Matrix4x4

Note that sometimes an exact match to the Unity equivalent wasn't possible. Furthermore, not every single method from these classes has been implemented. In general, this is only for methods whose double precision equivalent likely offers little practical benefit.

The complete details of any differences between the above classes and their Unity equivalents, including which methods are/aren't implemented, can be found here in the documentation:

https://robertjclose.github.io/DPML-documentation/

If you are looking for a double-precision version of a particular method, please check the documentation to ensure that it is supported by this package.

If a method is not supported, but you have found a good reason why it should be, please get in touch and I will do my best to add it!
