Documentation

Overview

package ms1 implements basic 1D math useful for 3D graphics applications. Functions in this package have their OpenGL equivalent which is usually of the same name.

Index

• func Clamp(v, Min, Max float32) float32
• func Interp(x, y, a float32) float32
• func Sign(x float32) float32
• func SmoothStep(edge0, edge1, x float32) float32

Functions

func Clamp

func Clamp(v, Min, Max float32) float32

Clamp returns value v clamped between Min and Max.

func Interp

func Interp(x, y, a float32) float32

Interp performs the linear interpolation between x and y, mapping with a in interval [0,1]. This function is known as "mix" in OpenGL.

func Sign

func Sign(x float32) float32

Sign returns -1, 0, or 1 for negative, zero or positive x argument, respectively, just like OpenGL's "sign" function.

func SmoothStep

func SmoothStep(edge0, edge1, x float32) float32

SmoothStep performs smooth cubic hermite interpolation between 0 and 1 when edge0 < x < edge1.
