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 ... 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

WebApr 16, 2024 · In GLSL, the types vec2, vec3, and vec4 represent 2D, 3D, and 4D floating-point vectors. (There are also types for integer and boolean vectors, which are not discussed here.) Vector variables are defined as you would expect if C, C++ or Java had these types: The data types for floating-point 2×2, 3×3, and 4×4 matrices are: mat2, mat3, and mat4 : Webgreater than. greater than - Elemental ASL Concepts More details.

WebI basically have a GLSL fragment shader that is giving me unexpected results, depending on whether it is executed using a NVIDIA Quadro, in which works as expected, or a NVIDIA GeForce, in which does something weird. 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).

WebMay 3, 2024 · 3 Answers Sorted by: 44 What causes branching in GLSL depends on the GPU model and OpenGL driver version. Most GPUs seem to have a form of "select one of two values" operation that has no branching cost: n = (a==b) ? x : y; and sometimes even things like: if (a==b) { n = x; m = y; } else { n = y; m = x; } WebThe above code can be 2 or 3 move instructions, depending on the compiler and the GPU's capabilities. Newer GPUs can handle setting different parts of gl_FragColor, but older …

WebThe greaterThan function returns a boolean vector as result of a component-wise comparison in the form of x i > y i. The function has two input parameters of the type floating point vector or signed integer vector. Greater than or equal comparison 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. WebAug 9, 2011 · Each component is compared to 0.2 using the built-in function greaterThan, and the result is stored in the bool vector toDiscard. The greaterThan function compares the two vectors component-wise, and stores the Boolean results in the corresponding components of the return value.
