WGSL Code
fn exponentialRamp(x: f32, base: f32, scale: f32, offset: f32) -> vec2<f32> { // Ensure base is positive and not 1 (which would make it linear) let b = select(base, 2.71828, abs(base - 1.0) < 0.001); // Calculate the exponential function let result = scale * pow(b, x) + offset; // Calculate the derivative let derivative = scale * pow(b, x) * log(b); return vec2<f32>(result, derivative); }
