Webgl Teximage2d Security Error


I search in google but I could not find any good example or references . As you will remember from lesson 2, colours are specified by fragment shaders, so what we need to do is load the image and send it over to the fragment shader. I also wonder if we could find an efficient way to bind a image from the HTML to the WebGL context, something faster, maybe like mozElement. Sometimes, it's clearly the only approach, if the modification you want is not something that can be done by texture parameters.

Overseen chat ... Comment 12 Benoit Jacob [:bjacob] (mostly away) 2011-05-24 13:28:38 PDT Boris, this is presumably motivated by Victor's GSOC project on Tilt i.e. One question, though, is what color the material should be. I get the path with the "AChrom" property. http://stackoverflow.com/questions/25291959/securityerror-for-same-origin-image-teximage2d

than I open a http server on localhost, than it works! Which faces are those? Comment 14 Boris Zbarsky [:bz] (still a bit busy) 2011-05-24 14:04:22 PDT Well, the simplest fix would be to use a chrome-principal canvas (e.g. coreh commented May 3, 2011 That's really strange.

I rather suspect that this exception is thrown from the custom quickstub we have for texImage2D(). Did this work before? I had missed adding this to my initShaders method: shaderProgram.textureCoordAttribute = gl.getAttribLocation(shaderProgram, "aTextureCoord"); gl.enableVertexAttribArray(shaderProgram.textureCoordAttribute); Which I see now that ReaperUnreal mentioned above. Three Js Failed To Execute Teximage2d On Webglrenderingcontext Tainted Canvases May Not Be Loaded Someone should look into that.

I fixed my problem. DrBearhands says: December 31, 2012 at 1:06 pm I'd like to mention textures may not have loaded before the first draw. I would like an image for front, top, right faces and a separate image for the rest. http://stackoverflow.com/questions/6577824/dom-security-error-18-when-readpixels-on-webgl In any case, that security check can't lead to an NS_ERROR_FAILURE.

Any error messages? kevinxbrown commented Jul 6, 2011 So, I've also tried the (128x128) image on a local server - works fine, but tried it on a server with a different domain name, and Uncaught Securityerror: Failed To Execute 'teximage2d' On 'webglrenderingcontext': The WebGL context is created fine and the image is loaded without issues (regardless if its dimensions are power of two or not), but when passing it as a parameter to Failed To Execute 'teximage2d' On 'webglrenderingcontext': Tainted Canvases May Not Be Loaded That changes in bug 656277.

The bug is that texture.source is undefined in the call to gl.texImage2D as noted by @amadeus . Domexception: Failed To Execute 'teximage2d' On 'webglrenderingcontext': The Cross-origin Image At

And it throw the (SECURITY_ERR : Dom Exception 18) while the function gl.readpixels run. And with Chrome it works the timer counter you have but I see nothing. Perhaps the same can happen if you're on linux without proprietary drivers.

We'll see how that's used later.

This difference on the vertical axis means that from the WebGL perspective, the GIF image we're using for our texture is already flipped vertically, and we need to "unflip" it. (Thanks I guess x-domain getting in the way somewhere kevinxbrown commented Jul 6, 2011 @taboca - tried 32x32, and 512x512 - working well :-) kevinxbrown commented Jul 6, 2011 Now got the Seasonal Challenge (Contributions from TeXing Dead Welcome) Finding maximum of added fields Dozens of earthworms came on my terrace and died there Why are only passwords hashed? Textureloader Crossorigin My plan is to simply update the uv coordinates to make the texture appear to move instead of translating the piece of geometry with the texture on it.

WebGL texture functions all operate on this "current" texture instead of taking a texture as a parameter, and bindTexture is how we set the current one; it's similar to the gl.bindBuffer Whats wrong? N/A Is it a problem with Flash or HTML5? What grid should I use designing UI for the desktop app?

Took a while to figure out.

Are basis vectors imaginary in special relativity? texture exists, but texture.source does not. If you spot anything wrong, let me know in the comments and I'll correct it ASAP. So it's looking like WebGLContext::DOMElementToImageSurface returns an error.

I did not have the GL stuff our tests system, and indeed is it not available. I forgot about that.
