Step
Generate a step function by comparing two values
Declaration
float step(float edge, float x)
vec2 step(vec2 edge, vec2 x)
vec3 step(vec3 edge, vec3 x)
vec4 step(vec4 edge, vec4 x)
vec2 step(float edge, vec2 x)
vec3 step(float edge, vec3 x)
vec4 step(float edge, vec4 x)
Parameters
edge specifies the location of the edge of the step function.
x specify the value to be used to generate the step function.
Description
step() generates a step function by comparing x to edge.
For element i of the return value, 0.0 is returned if x[i] < edge[i], and 1.0 is returned otherwise.
