A quadratic function is a polynomial equation of degree two which typically takes the form of y = ax^2 + bx + c, where a, b, and c are constants. The vertex of a quadratic function is the point that ...

where a, b, and c are numerical constants and c is not equal to zero. Note that if c were zero, the function would be linear. An advantage of this notation is that it can easily be generalized by ...

Currently, in webgl, when the fill function is called immediately before the vertex function in immediateMode to determine the color, each vertex is colored and a gradation is applied. However, doing ...
