LYGIA Shader Library

scale2d (lygia/math/scale2d)

returns a 2x2 scale matrix

Use:

<mat2> scale2d(<float|vec2> radians)
<mat2> scale2d(<float> x, <float> y)

Check it on Github


#ifndef FNC_SCALE2D
mat2 scale2d(float s) { return mat2(s, 0.0, 0.0, s); }
mat2 scale2d(vec2 s) { return mat2(s.x, 0.0, 0.0, s.y); }
mat2 scale2d(float x, float y) { return mat2(x, 0.0, 0.0,  y); }
#endif

Use:

<float2x2> scale2d(<float|float2> radians)
<float2x2> scale2d(<float> x, <float> y)
