GLSL Greater Than or Equal Function Documentation

The greaterThanEqual() function in GLSL is used to compare two values and return a boolean result indicating whether the first value is greater than or equal to the second value.

Syntax

bool greaterThanEqual(T x, T y)

• x: The first value to be compared, of any type T.
• y: The second value to be compared, of the same type T as x.

Return Value

The greaterThanEqual() function returns a boolean value indicating whether x is greater than or equal to y. If x is greater than or equal to y, it returns true. Otherwise, it returns false.

Example usage:

float a = 5.0;
float b = 3.0;
bool result = greaterThanEqual(a, b); // Returns true

int x = 10;
int y = 20;
bool result = greaterThanEqual(x, y); // Returns false

vec3 p = vec3(1.0, 2.0, 3.0);
vec3 q = vec3(1.0, 0.0, 5.0);
bvec3 result = greaterThanEqual(p, q); // Returns bvec3(true, true, false)

Notes

• The greaterThanEqual() function can only be used with numerical data types (float, int, uint, double) and vectors/matrices composed of numerical data types.
• The comparison is performed element-wise in the case of vectors and matrices.
• For vectors and matrices, the greaterThanEqual() function returns a boolean vector/matrix in which each element of the result corresponds to the comparison of the respective elements of the input vectors/matrices.
• The greaterThanEqual() function is part of the GLSL version 1.20 specification and is supported by most modern GPUs.
