uncenter: Centered to Normalized Range Transform

Coordinate transformation from centered to normalized space

The uncenter functions transform coordinates from a centered range [-1, 1] to a normalized range [0, 1]. This is the inverse operation of the center function.

For any input value v, the transformation applies:

$$\text{uncenter}(v) = v \times 0.5 + 0.5$$

This linear transformation maps:

• -1 → 0
• 0 → 0.5
• 1 → 1

Available Functions

Function	Input Type	Output Type	Description
uncenterFloat	float	float	Transform single value
uncenterVec2	vec2	vec2	Transform 2D vector
uncenterVec3	vec3	vec3	Transform 3D vector
