WebJust like GLSL ES 3.0, implicit casting between scalars and vectors of the same size but different type is not allowed. Casting of types of different size is also not allowed. Conversion must be done explicitly via constructors. Example: float a = 2; // valid float a = 2.0; // valid float a = float(2); // valid. WebJan 18, 2008 · So, I just multiply the result of atan by 2.0 to get the same result as the HLSL atan2 function. No, HLSL atan2(x,y) == GLSL atan(y,x) GLSL provides two atan-operators.
