I’m confused now. The class is named WebGLRenderingContext in JS (I think
that’s what it’s called by JS doesn’t really have classes does it?) so how does
it look?
// no external name because the names are the same
type
WebGLRenderingContext = class
procedure clearColor (red, green, blue, alpha: GLfloat);
end;
So constants must be part of the class? In the example below
gl.COLOR_BUFFER_BIT is scoped to WebGLRenderingContext so I guess that’s the
reason.
Also I mistyped, GLfloat is a type so how do this map to JS, or do I even need
to since the names are the same?
How does this JS translate to Pascal then? drawingBufferWidth are read only
properties but no type is specified so how does Pascal handle all the untyped
variables we see in JS?
var canvas = document.createElement("canvas");
var gl = canvas.getContext("webgl")
gl.viewport(0, 0, gl.drawingBufferWidth, gl.drawingBufferHeight);
gl.clearColor(0, 0, 0, 0);
gl.clear(gl.COLOR_BUFFER_BIT);
