ivec4 y) The greaterThan function returns a boolean vector as result of a component-wise comparison in the. In case of a float vector every component is converted from radians to degrees separately. Z.0 dist.0) gl_FragColor. The reflection vector always has the same length as the incident vector. Float acos(float x) vec2 acos(vec2 x) vec3 acos(vec3 x) vec4 acos(vec4 x the acos function returns the arccosine of an angle in radians. The first two texcoords can stay as they are, and the third can be directly used to select an arbitrary blending between two neighboring slices. Bvec2 equal(vec2 x, vec2 y) bvec3 equal(vec3 x, vec3 y) bvec4 equal(vec4 x, vec4 y) bvec2 equal(ivec2 x, ivec2 y) bvec3 equal(ivec3 x, ivec3 y) bvec4 equal(ivec4 x, ivec4 y) The equal function returns a boolean vector as result of a component-wise comparison in the. Float faceforward(float N, float I, float Nref) vec2 faceforward(vec2 N, vec2 I, vec2 Nref) vec3 faceforward(vec3 N, vec3 I, vec3 Nref) vec4 faceforward(vec4 N, vec4 I, vec4 Nref) The faceforward function returns a vector that points in the same direction as a reference vector.

Float step(float edge, float x) vec2 step(float edge, vec2 x) vec3 step(float edge, vec3 x) vec4 step(float edge, vec4 x) There is also a variation of the step function where the edge parameter is always a floating scalar. The "center" of the i-th slice will lie at pi/num_layers 1 2*num_layers say you have those 3 slices for ice, stone and grass. Float step(float edge, float x) vec2 step(vec2 edge, vec2 x) vec3 step(vec3 edge, vec3 x) vec4 step(vec4 edge, vec4 x) The step function returns.0 if x is smaller then edge and otherwise.0. If that is the case, you can simply use 3D textures and use (tri)linear filtering. The variants of where a is genBType select which vector each returned component comes from. In case of a float vector the arctangent is calculated separately for every component. Rgb -.0 * gl_FragColor. Otherwise the return value is interpolated between.0 and.0 using Hermite polynomials.

Edit this page on GitHub. A vector that is perpendicular to the plane containing x and y and has a magnitude that is equal to the area of the parallelogram that x and y span. Side note: On iOS devices texture lookup functionality is only available in the fragment shader. The function has one input parameter of the type samplerCube and one input parameter of the type vec3 : sampler, the uniform the texture is bound to, and coord, the 3-dimensional coordinates of the texel to look. X / k; gl_Position vec4(x, aVertexPosition. Float mod(float x, float y) vec2 mod(vec2 x, float y) vec3 mod(vec3 x, float y) vec4 mod(vec4 x, float y) There is also a variation of the mod function where the second parameter is always a floating scalar. Float sin(float angle) vec2 sin(vec2 angle) vec3 sin(vec3 angle) vec4 sin(vec4 angle). It is the inverse function of cosine. For a point with Cartesian coordinates (x, y) the function returns the angle of the same point with polar coordinates (r, ).

Mat4 c a * b; vec4 v? In case of a float vector the cosine is calculated separately for every component. This material may be distributed subject to the terms and conditions set forth in the Open Publication License,.0. It is the inverse function of sine.
