as the right edge. GenType step(genType edge, genType value genType step(float edge, genType value Like many functions in, gLSL, has parameters and return values with the type. Later chapters will build on these examples. Float sign(float x) vec2 sign(vec2 x) vec3 sign(vec3 x) vec4 sign(vec4 x) The sign function returns.0 when x is positive,.0 when x is zero and -1.0 when x is negative.

The function has three input parameters of the type floating scalar or float vector: N, the vector to orient, I, the incident vector, and Nref, the reference vector. Rotated circle fragment shader 1 #define M_PI. Hermite polynomial, between 0 and 1 otherwise. In Figure 11, Output of circle fragment shader that uses the black pixels are the background color. The function has two input parameters of the type floating scalar or float vector and one input parameter of the type floating scalar: I, the incident vector, N, the normal vector of the refracting surface, and eta, the ratio of indices of refraction. The following implementations produce viable raw noise for 2d or 3d coordinates: float rand2D(in vec2 co) return fract(sin(dot(co. GenType smoothstep (genType low_edge, genType high_edge, genType value genType smoothstep (float low_edge, float high_edge, genType value Figure. .
