isWebGL2

This function checks if an existing WebGL context is a WebGL2RenderingContext

Method

isWebGL2

A major check that can be done is whether you are working with a WebGL2RenderingContext. An advantage of using this method is that it can correctly identify a luma.gl debug context (which is not a subclass of a WebGL2RendringContext).

isWebGL2(gl)

• gl (WebGLRenderingContext) - gl context Returns true if the context is a WebGL2RenderingContext.
