Detector

Module for checking if certain browser features are available, and for getting WebGL context parameters.

Methods

# .checkWebGL() → Boolean

Checks if a WebGL 1.0 context can be obtained.

# .checkWebGL2() → Boolean

Checks if a WebGL 2.0 context can be obtained.

# .checkWorkers() → Boolean

Checks if Web Workers API is available.

# .checkFileAPI() → Object

Returns last API namespace found in the list: File, FileReader, FileList, Blob.

# .genWebGLErrorMessage() → HTMLElement

Creates an HTML element with the WebGL non-availability message and the link to the troubleshooting page.

# .showWebGLErrorMessage(elem : HTMLElement)

Generates and shows the WebGL non-availability message by appending it as child to the specified element (or document body if no element is specified).

# .checkIOS() → Boolean

Retrieves user agent information and finds if it is running on iPhone, iPad, or iPod.

# .checkAndroid() → Boolean

Retrieves user agent information and finds if it is running on Android.

# .checkFloatTex(renderer : WebGLRenderer, requireLinear : Boolean) → Boolean

Check if float textures are available for rendering.

# .checkHalfFloatTex(renderer : WebGLRenderer, requireLinear : Boolean) → Boolean

Check if half-float textures are available for rendering.

# .checkHalfFloatReadPixels(renderer : WebGLRenderer) → Boolean

Check if you can read pixels from half-float render target.

# .checkFloatReadPixels(renderer : WebGLRenderer) → Boolean

Check if you can read pixels from float render target.

# .checkDepthTex(renderer : WebGLRenderer) → Boolean

Check if depth textures are available for rendering.

# .getGPUVendor(renderer : WebGLRenderer) → String

Returns the UNMASKED_VENDOR_WEBGL parameter of the WEBGL_debug_renderer_info extension. If the latter is not present, returns empty string value.

# .getGPUModel(renderer : WebGLRenderer) → String

Returns the UNMASKED_RENDERER_WEBGL parameter of the WEBGL_debug_renderer_info extension. If the latter is not present, returns empty string value.

# .checkWebXR() → Boolean

Check if WebXR API (VR) API is available.

# .checkSwiftShader(renderer : WebGLRenderer) → Boolean

Check if only Swift Shader software rasterizer is available for rendering.

# .checkWebAudio() → Boolean

Check if WebAudio API is available.

# .checkTouchDevice() → Boolean

Check if touch device is available.

Puzzles

The feature available and get GPU puzzles allow to access most of these methods without coding.
