Основы синтаксиса языка должны быть знакомы любому C-программисту. ... bool4 greaterThan(int4 x, int4 y) bool2 greaterThan(float2 x, … WebMath functions: pow, sqrt, inversesqrt, exp, exp2, log, log2. 'sqrt' works the same as in GML, pow is the equivalent to the GML power, 'inversesqrt' is the reciprocal of the square root, the "exp" functions are exponential functions and the "log" are logarithms with different bases (The Natural Number and 2). Vector functions:

WebOne expression might be better than the other. For example: result = 0.5 * (1.0 + variable); result = 0.5 + 0.5 * variable; The first one may be converted into an add followed by a multiply. The second one is expressed in a way that more explicitly allows for a MAD operation. Assignment with MAD Webstep 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. flakes twitter

WebgreaterThanEqual — perform a component-wise greater-than-or-equal comparison of two vectors. Declaration. bvec greaterThanEqual(vec x, vec y); bvec greaterThanEqual(ivec x, ivec y); bvec greaterThanEqual(uvec x, uvec y); Parameters. x. Specifies the first vector to be used in the comparison operation. y. Specifies the second vector to be used ... WebAlso GLSL has special vector relational functions such as: lessThan(), lessThanEqual(), greaterThan(), greaterThanEqual(), equal() and notEqual(). Once we obtain the angle and length we need to “normalize” … WebNov 8, 2013 · vec3 v1 = vec3 (1,2,3); vec3 v2 = vec3 (3,2,1); bvec3 gt = greaterThan (v1, v2); Then the boolean vector gt would have the following form: gt.x = false; gt.y = false; gt.z = true; However, the biggest problem you have is you are trying to modify an input value. flake technology
