WebThe basic scalar type constructors can be used to convert values from one type to another. What you get depends on the kind of conversion. from bool. If it is false, then you get 0, in whatever the output type is (floating-point types get 0.0). If it is true, then you get 1, in whatever the output type is. to bool. WebIt is possible to set the size of the points being rendered via OpenGL's glPointSize function, but we can also influence this value in the vertex shader. One output variable defined by GLSL is called gl_PointSize that is a float variable where you can set the point's width and height in pixels. By setting the point's size in the vertex shader ...
