WebName. length — calculate the length of a vector. Declaration. float length(: genType x); WebDirect vector assignment is reference rather than copy, that is: in the following statement: var ref = original, 'ref' represents the same underlying vector as 'original', whereas in GLSL it would be a copy. To copy a vector you can do any of var copy = original.clone(), var copy = vec3(original) or var copy = original.xyz. When accessing sub ...

WebMay 18, 2024 · Uniforms are intended to be set by the user from OpenGL, rather than within the shader. However, you can initialize them to a default value using standard GLSL initalizer syntax : uniform vec3 initialUniform = vec3(1.0, 0.0, 0.0); This will cause the uniform to have this vector as its value, until the user changes it.

Web1 Answer. The easiest think to do is to pass as a uniform the position of the camera in World-Space and calculate the direction from the vertex to the camera and then calculate the dot product between that direction and the vertex normal.

WebMar 31, 2024 · In GLSL (specifically 3.00 that I'm using), there are two versions of atan(): atan(y_over_x) can only return angles between -PI/2, PI/2, while atan(y/x) can take all 4 quadrants into account so the angle range covers everything from -PI, PI, much like atan2() in C++. ... If y=0 too, the angle can be arbitrary (vector has length 0). sign(y ...
