BTW, to you use WebGL as of now, you essentially need Canvas. WebGL is different from Canvas only in the sense that you get a WebGL Context. WebGL - document.getElementById('canvas-element').getContext( webgl );.

Convert a webgl context or a webgl canvas into a 2d canvas.

You are using an out of date browser. It may not display this or other websites correctly.You should upgrade or use an alternative browser. Anyone knows Canvas blocking extension for Opera? I use Yandex, which keeps moving towards Opera, so Chrome extensions keep stopping working, like CanvasFingeprintblock now. Anyone tried TunnelBear Blocker? It seems to work pretty well for me in Chrome. jacemace Registered Member Joined: Sep 10, 2009 Posts: 78 Hi, I got %100 on - "0 user agents have the same signature"; is this a good outcome or not? Is it easier to identify etc.? I'd say, that depends. Quite generally this result means that you're perfectly identifiable. However, if you're using an add-on like Canvas Defender which creates noise by creating a new fingerprint with every browsing session or even every x minutes this result is basically meaningless, IMHO. By any chance, is your signature 5820BEE4 ? Just thinking, that maybe blocking canvas displays some default signature/file. Attached Files: a"> The webExtension version of CanvasBlocker is available (Beta):Version 0.4.0: changes: - switched to webExtension - notifications are now done via page action - minimal and maximal fake size are now respected in all fakeable functions - fake readout now fakes one pixel at once and no longer one single channel - new icon (special thanks to Thorin-Oakenpants) new features: - information of all fake events in one tab are visible - settings page now only shows settings that are useful within the given settings set - new preferences: * minimal fake size * setting to enable the inspection of the content of the faked canvas * new random number generator "constant" * setting to not fake the most frequent colors in a canvas * setting to enable canvas cache * setting to hide expert settings * setting to control if the alpha channel should be faked as well fixes: - ask mode did not work for input types - allow page scripts to overwrite the faked funtions - getImageData also faked when using fakeInput mode Last edited by a moderator: Sep 24, 2017 I checked Chrome @ and it shows that WebGL is enabled, which is correct I guess, but should we disable it? I've found Disable WeGL in the Chrome store which works, but I don't know what the implications of disabling WeGL are?Any advice appreciated. I disabled it using the Disable WebGL extensionWhat is WebGL and why it’s dangerous?WebGL (Web-based Graphics Library) is a collection of code for JavaScript that makes it possible for a website to access your video card in order to display interactive 3D-graphics using the HTML5 Canvas element—without using any third-party plug-ins.WebGL can be a threat to your device security and online anonymity. Cool, thanks!So does disabling WebGL only stop the fingerprinting or does it disable part of the browsers capability and function too. I don't see my browser affected in any way since I'm not using any 3D software Ah, gotcha. After disabling it i don't see any negative effects

javascript - passing a webgl canvas to

GlUtilsglUtils is a bare-bones WebGL library abstracting away the more common boilerplate WebGL code,while still allowing one to use the API directly.Demonstrations of glUtils functionality can be found in the examples directory and in most of my WebGL experiments.UsageThe WebGL context is acquired using glUtils.getGL(), passing a canvas element to it as argument (it is assumed the canvas has already had its width and height set): var gl = glUtils.getGL(document.getElementById("webgl"));A program is set up using glUtils.getProgram() and passing it the WebGL context, and the ids of elementsin the page containing the vertex and fragment shader code: var program = glUtils.getProgram(gl, "vertex-shader", "fragment-shader");Any errors in the compilation or linking will be printed to the console.References to shader attributes and uniforms can be acquired using glUtils.getGLVars(): var gl_vars = glUtils.getGLVars(gl, program, { attributes: ["aPosition", "aColor"], uniforms: ["uMVP"] });glUtils.getGLVars() returns an object containing the variable names as keys and their referencesas values, e.g. gl_vars.aPosition, gl_vars.uMVP.Attribute buffers can be prepared using glUtils.setBuffer(), passing the WebGL context,attribute reference, data and item size as arguments. The created buffer object is returned: var position_buffer = glUtils.setBuffer(gl, gl_vars.aPosition, vertices, 3);When switching between programs, it might be necessary to rebind buffer objects,and this can be done using glUtils.enableBuffer(), passing the WebGL context,attribute reference, buffer object and item size as arguments: glUtils.enableBuffer(gl, gl_vars.aPosition, position_buffer, 3);Textures can be loaded using glUtils.loadTexture(), which takes the WebGLcontext, texture unit and image object as arguments: glUtils.loadTexture(gl, gl.TEXTURE0, texture_image);glUtils.loadTexture() defaults to common options for filtering and wrap modes. These can be overridden by passing it additional options: glUtils.loadTexture(gl, gl.TEXTURE0, texture_image, { min_filter: gl.LINEAR, mag_filter: gl.LINEAR, wrap_s: gl.CLAMP_TO_EDGE, wrap_t: gl.CLAMP_TO_EDGE });glUtils also provides two utility methods for creating the geometry of basic shapes: var sphere = glUtils.createSphere({ long_bands: 32, lat_bands: 32, radius: 1 }); var box = glUtils.createBox({ dimensions: [1, 2, 1] });Both return objects containing properties vertices, the vertex positions, normals, the vertex normals, andtexture_coords, the texture coordinates.Math ModulesglUtils provides two modules, glUtils.vec3 and glUtils.mat4, to help with common mathematical operations on the typed arrays used by WebGL. The API for these modules is heavily influenced by gl-matrix.glUtils.vec3 provides the following functions:vec3.create(x, y, z): create a vec3 (a 3-element Float32Array). Elements will default to 0.vec3.copy(v1, v2): copy elements of v2 into v1.vec3.clone(v): create a clone of v.vec3.length(v): calculate the length of vector v.vec3.scale(v, s): scale vector v by a factor of s.vec3.normalize(v): normalize vector v.vec3.add(out, v1, v2): add vectors v1 and v2, store result in out.vec3.sub(out, v1, v2): subtract vector v2 from vector v1, store result in out.vec3.dot(v1, v2): calculate the dot product of vectors v1 and v2.vec3.cross(out, v1, v2): calculate the cross product of vectors v1 and v2, store result in out.vec3.applyMat4(out, m, v, vector_transform): apply transformation represented by matrix m to the vector

WebGL - canvas and getContext - ProgrammingTIL

--> Modern JavaScript is surprisingly powerful. Especially with support from WebGL libraries and SVG/Canvas elements.With the right tools you can build pretty much anything for the web including browser-based games and native applications. Many of the newest groundbreaking features run on 3D, and in this post I’ve curated my list of the best 3D JS libraries currently available for web developers.Three.jsThere is no doubt that Three.js deserves to be at the top of this list. It can be somewhat complex to learn from scratch but it’s also one of the better 3D libraries out there.It’s managed by a core group and released for free on GitHub. ThreeJS primarily works on canvas elements, SVG elements, and the WebGL library for rendering.Learning the ropes is a challenge and will require at least mid-level JavaScript knowledge. But you can find the complete setup in the Three.js documentation.If you’re serious about doing 3D on the web, this library is for you. It’s not the only choice, but it’s probably the most popular choice for a beginner to start building stuff fast.Babylon.jsAnother powerful library I like is Babylon.js. This one again relies on WebGL and runs solely in JavaScript.It’s a bit more popular than other libraries but doesn’t have the same reach as Three.js.Still it’s widely regarded as a powerful choice for web developers who want to create browser-based web games. On the homepage you can find a ton of demo previews and tips on how to get started with 3D game design.There’s also a bunch of important links to resources like the GitHub repo and the Babylon JS tutorials.All of those tutorials were designed by the Babylon team, so they’re an excellent place to start learning this library.Cannon.jsFor something a little off the beaten path check out Cannon.js. This doesn’t push the usual 3D concepts but instead works as a JavaScript-based physics engine for gaming.Canon is meant to load fast so you can render elements quickly on the page. It supports most modern browsers and comes with a powerful API for building your own physics ideas off of this.It works great with Canvas elements

Your existing FLA projects (of any type) to any other document type such as HTML5 Canvas, ActionScript/AIR, WebGL, or a custom document type. When you convert to a format, you can take advantage of the authoring features that Animate offers for that document type. For more information, see Convert to other document formats Converting ActionScript 3 to HTML5 Canvas document using JSFL script Animate provides a JSFL script to convert an AS3 document to HTML5 Canvas document. When run, the JSFL script does the following: Creates a new HTML5 Canvas document. Copies all layers, symbols, and library items to the new HTML5 Canvas document. Applies defaults to unsupported features, subfeatures, or feature-properties. Creates separate FLA files for each scene, because HTML5 Canvas document does not support multiple scenes. To convert an AS3 document to HTML5 Canvas document, do the following: Open the ActionScript 3 document in Animate. Select Commands > Convert AS3 to HTML5 Canvas document. This is applicable only when Combine images into spritesheet option is unchecked.. BTW, to you use WebGL as of now, you essentially need Canvas.
