IWebGLContext

class IWebGLContext()

A useful wrapper over the WebGL context.

Properties

IWebGLContext.clear_color: IVec4

A vec4() instance defining the color to use when clearing the WebGL context.

IWebGLContext.div: HTMLCanvasElement
IWebGLContext.gl: WebGLRenderingContext

The raw WebGL context created for the canvas.

You can use any valid WebGL routine on that context.

Methods

IWebGLContext.checkGLError()

Verifies the state of the WebGL context, and prints any error in both the JavaScript console, and in an alert box.

Returns:any
IWebGLContext.clear()

Erases both the color and depth of the WebGLContext.

Returns:any
