Glsl arctan
WebArctan calculator; Arctan definition. The arctangent of x is defined as the inverse tangent function of x when x is real (x ∈ℝ). When the tangent of y is equal to x: tan y = x. Then the arctangent of x is equal to the inverse tangent function of x, which is equal to y: arctan x= tan-1 x = y. Example. arctan 1 = tan-1 1 = π/4 rad = 45 ... 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 :
