  • The Texture() method of the WebGL API specifies which texture unit to make active. This article is a continuation of WebGL Image Processing.

    Multiple textures in WebGL

    return the WebGL API; return {; activeTexture: activeTexture,; bindTexture: bindTexture. As a prerequisite you probably want to read How WebGL Works and WebGL Shaders If activeTexture and bindTexture WebGL functions were implemented in.
    I found on mozilla dev site : "GL provides 32 texture registers; the first of these is gl.

    RGBA, gl. It creates a new Image object, sets the URL to load, and sets a callback to be called when the image finishes loading.

    WebGL Using 2 or More Textures

    Hopefully this small step helps explain how to use mutliple textures in a single draw call in WebGL. Setup a private space for you and your coworkers to ask questions and share information.

    When imagesToLoad goes to 0 all the images have been loaded and we pass the array of images to a callback. In WebGL1 it's 8. Stack Overflow works best with JavaScript enabled.

    WebGL and WebGL2 have as many texture units as the driver/GPU supports activeTexture(gl.

    bind a texture to texture unit 7 var unit = 7; gl. This is made with WebGL, where the fragment shader combines two textures:. activeTexture, but we do not use them in the shader uniforms!. Name. activeTexture — select active texture unit. Specification. void activeTexture(GLenum texture). Parameters. texture specifies which.
    You can think of it as an array of references to textures.

    First we set imagesToLoad to the number of images we're going to load. WebGL has something called "texture units". In this case we'll wait for all the images to load before we draw anything. In WebGL1 it's 8. Sign up or log in Sign up using Google.

    In the book OpenGL programming guide, Example uses two texture objects and it does not call glActiveTexture before calling glBindTexture.

    webgl documentation: Textures. Calling xture binds a texture to the active texture unit like this // pseudo code xture = function(target, texture ). uDoTexturing = formLocation(glProgram, "uDoTexturing"); m1i( turing, 1); } function setupTexture(i) { Texture(gl.
    Each texture unit has 2 targets.

    So, if you used 2 in a vertex shader you could only use 6 a linked fragment shader for a total of 8.

    If you haven't read that I suggest you start there. The "active texture unit" is just a global variable that's the index of the texture unit you want to work with.

    4. If you need to use more than 8 on WebGL1 or more than 32 in WebGL2 you should query how many are available and either tell the user they can't use your site or fallback to some simpler method that works within the minimums. Featured on Meta.
