Package net.minecraft.util.math
Class MathHelper
java.lang.Object
net.minecraft.util.math.MathHelper
Contains math-related helper methods. This includes
float
-specific extensions
to Math
, linear interpolation (lerp), and color-related methods.
Trigonometric functions defined in this class use the "sine table", a pre-calculated
table of sin(N)
(0 <= N < pi * 2
).

catmullRom
public static float catmullRom(float delta, float p0, float p1, float p2, float p3) Interpolates a point on a Catmull-Rom Spline. This spline has a property that if there are two splines with argumentsp0, p1, p2, p3
andp1, p2, p3, p4
, the resulting curve will have a continuous first derivative atp2
, where the two input curves connect. For higher-dimensional curves, the interpolation on the curve is done component-wise: for inputsdelta, (p0x, p0y), (p1x, p1y), (p2x, p2y), (p3x, p3y)
, the output is(catmullRom(delta, p0x, p1x, p2x, p3x), catmullRom(delta, p0y, p1y, p2y, p3y))
.- Parameters:
delta
- the progress along the interpolationp0
- the previous data point to assist in curve-smoothingp1
- the output ifdelta
is 0p2
- the output ifdelta
is 1p3
