* @property {number} [width] the width of the texture. Only used if src is an array or typed array or null.
|
|
* @property {number} [height] the height of a texture. Only used if src is an array or typed array or null.
|
|
* @property {number} [min] the min filter setting (eg. `gl.LINEAR`). Defaults to `gl.NEAREST_MIPMAP_LINEAR`
|
|
* or if texture is not a power of 2 on both dimensions then defaults to `gl.LINEAR`.
|
|
* @property {number} [mag] the mag filter setting (eg. `gl.LINEAR`). Defaults to `gl.LINEAR`
|
|
* @property {number} [format] format for texture. Defaults to `gl.RGBA`.
|
|
* @property {number} [type] type for texture. Defaults to `gl.UNSIGNED_BYTE` unless `src` is ArrayBuffer. If `src`
|
|
* is ArrayBuffer defaults to type that matches ArrayBuffer type.
|
|
* @property {number} [wrap] Texture wrapping for both S and T. Defaults to `gl.REPEAT` for 2D and `gl.CLAMP_TO_EDGE` for cube
|
|
* @property {number} [wrapS] Texture wrapping for S. Defaults to `gl.REPEAT` and `gl.CLAMP_TO_EDGE` for cube. If set takes precedence over `wrap`.
|
|
* @property {number} [wrapT] Texture wrapping for T. Defaults to `gl.REPEAT` and `gl.CLAMP_TO_EDGE` for cube. If set takes precedence over `wrap`.
|
|
* @property {number} [unpackAlignment] The `gl.UNPACK_ALIGNMENT` used when uploading an array. Defaults to 1.
|
|
* @property {number} [premultiplyAlpha] Whether or not to premultiply alpha. Defaults to whatever the current setting is.
|
|
* This lets you set it once before calling `twgl.createTexture` or `twgl.createTextures` and only override
|
|
* the current setting for specific textures.
|
|
* @property {number} [flipY] Whether or not to flip the texture vertically on upload. Defaults to whatever the current setting is.
|
|
* This lets you set it once before calling `twgl.createTexture` or `twgl.createTextures` and only override
|
|
* the current setting for specific textures.
|
|
* @property {number} [colorspaceConversion] Whether or not to let the browser do colorspace conversion of the texture on upload. Defaults to whatever the current setting is.
|
|
* This lets you set it once before calling `twgl.createTexture` or `twgl.createTextures` and only override
|
|
* the current setting for specific textures.
|
|
* @property {(number[]|ArrayBuffer)} color color used as temporary 1x1 pixel color for textures loaded async when src is a string.
|
|
* If it's a JavaScript array assumes color is 0 to 1 like most GL colors as in `[1, 0, 0, 1] = red=1, green=0, blue=0, alpha=0`.
|
|
* Defaults to `[0.5, 0.75, 1, 1]`. See {@link module:twgl.setDefaultTextureColor}. If `false` texture is set. Can be used to re-load a texture
|
|
* @property {boolean} [auto] If not `false` then texture working filtering is set automatically for non-power of 2 images and
|
|
* mips are generated for power of 2 images.
|
|
* @property {number[]} [cubeFaceOrder] The order that cube faces are pulled out of an img or set of images. The default is
|
|
*
|
|
* [gl.TEXTURE_CUBE_MAP_POSITIVE_X,
|
|
* gl.TEXTURE_CUBE_MAP_NEGATIVE_X,
|
|
* gl.TEXTURE_CUBE_MAP_POSITIVE_Y,
|
|
* gl.TEXTURE_CUBE_MAP_NEGATIVE_Y,
|
|
* gl.TEXTURE_CUBE_MAP_POSITIVE_Z,
|
|
* gl.TEXTURE_CUBE_MAP_NEGATIVE_Z]
|
|
*
|
|
* @property {(number[]|ArrayBuffer|HTMLCanvasElement|HTMLImageElement|HTMLVideoElement|string|string[]|module:twgl.TextureFunc)} [src] source for texture
|
|
*
|
|
* If `string` then it's assumed to be a URL to an image. The image will be downloaded async. A usable
|
|
* 1x1 pixel texture will be returned immediatley. The texture will be updated once the image has downloaded.
|
|
* If `target` is `gl.TEXTURE_CUBE_MAP` will attempt to divide image into 6 square pieces. 1x6, 6x1, 3x2, 2x3.
|
|
* The pieces will be uploaded in `cubeFaceOrder`
|
|
*
|
|
* If `string[]` then it must have 6 entries, one for each face of a cube map. Target must be `gl.TEXTURE_CUBE_MAP`.
|
|
*
|
|
* If `HTMLElement` then it wil be used immediately to create the contents of the texture. Examples `HTMLImageElement`,
|
|
* `HTMLCanvasElement`, `HTMLVideoElement`.
|
|
*
|
|
* If `number[]` or `ArrayBuffer` it's assumed to be data for a texture. If `width` or `height` is
|
|
* not specified it is guessed as follows. First the number of elements is computed by `src.length / numComponets`
|
|
* where `numComponents` is derived from `format`. If `target` is `gl.TEXTURE_CUBE_MAP` then `numElements` is divided
|
|
* by 6. Then
|
|
*
|
|
* * If neither `width` nor `height` are specified and `sqrt(numElements)` is an integer then width and height
|
|
* are set to `sqrt(numElements)`. Otherwise `width = numElements` and `height = 1`.
|
|
*
|
|
* * If only one of `width` or `height` is specified then the other equals `numElements / specifiedDimension`.
|
|
*
|
|
* If `number[]` will be converted to `type`.
|
|
*
|
|
* If `src` is a function it will be called with a `WebGLRenderingContext` and these options.
|
|
* Whatever it returns is subject to these rules. So it can return a string url, an `HTMLElement`
|
|
* an array etc...
|
|
*
|
|
* If `src` is undefined then an empty texture will be created of size `width` by `height`.
|
|
*
|
|
* @property {string} [crossOrigin] What to set the crossOrigin property of images when they are downloaded.
|
|
* default: undefined. Also see {@link module:twgl.setDefaults}.

|
|
* twgl.setDefaults({ attribPrefix: 'a_' });

|
* attribPrefix: 'a_',

|
|
*
|
|
* @typedef {Object} Defaults
|
|
* @property {string} attribPrefix The prefix to stick on attributes
|
|
*
|
|
* When writing shaders I prefer to name attributes with `a_`, uniforms with `u_` and varyings with `v_`
|
|
* as it makes it clear where they came from. But, when building geometry I prefer using unprefixed names.
|
|
*
|
|
* In otherwords I'll create arrays of geometry like this
|
|
*
|
|
* var arrays = {
|
|
* position: ...
|
|
* normal: ...
|
|
* texcoord: ...
|
|
* };
|
|
*
|
|
* But need those mapped to attributes and my attributes start with `a_`.
|
|
*
|
|
* Default: `""`
|
|
*
|
|
* @property {number[]} textureColor Array of 4 values in the range 0 to 1
|
|
*
|
|
* The default texture color is used when loading textures from
|
|
* urls. Because the URL will be loaded async we'd like to be
|
|
* able to use the texture immediately. By putting a 1x1 pixel
|
|
* color in the texture we can start using the texture before
|
|
* the URL has loaded.
|
|
*
|
|
* Default: `[0.5, 0.75, 1, 1]`
|
|
*
|
|
* @property {string} crossOrigin
|
|
*
|
|
* If not undefined sets the crossOrigin attribute on images
|
|
* that twgl creates when downloading images for textures.
|
|
*
|
|
* Also see {@link module:twgl.TextureOptions}.
|
|
*
|
|
* @property {bool} enableVertexArrayObjects
|
|
*
|
|
* If true then in WebGL 1.0 will attempt to get the `OES_vertex_array_object` extension.
|
|
* If successful it will copy create/bind/delete/isVertexArrayOES from the extension to
|
|
* the WebGLRenderingContext removing the OES at the end which is the standard entry point
|
|
* for WebGL 2.
|
|
*
|
|
* Note: According to webglstats.com 90% of devices support `OES_vertex_array_object`.

* functions will create a new matrix. In other words you can do this
|
|
*
|
|
* var mat = m4.translation([1, 2, 3]); // Creates a new translation matrix

|

* or

|
|
* m4.translation([1, 2, 3], mat); // Puts translation matrix in mat.
|
|
*
|
|
* The first style is often easier but depending on where it's used it generates garbage where
|
|
* as there is almost never allocation with the second style.
|
|
*
|
|
* It is always save to pass any matrix as the destination. So for example
|
|
*
|
|
* var mat = m4.identity();
|
|
* var trans = m4.translation([1, 2, 3]);
|
|
* m4.multiply(mat, trans, mat); // Multiplies mat * trans and puts result in mat.

/**
|
|
* Various functions to make simple primitives
|
|
*
|
|
* note: Most primitive functions come in 3 styles
|
|
*
|
|
* * `createSomeShapeBufferInfo`
|
|
*
|
|
* These functions are almost always the functions you want to call. They
|
|
* create vertices then make WebGLBuffers and create {@link module:twgl.AttribInfo}s
|
|
* returing a {@link module:twgl.BufferInfo} you can pass to {@link module:twgl.setBuffersAndAttributes}
|
|
* and {@link module:twgl.drawBufferInfo} etc...
|
|
*
|
|
* * `createSomeShapeBuffers`
|
|
*
|
|
* These create WebGLBuffers and put your data in them but nothing else.
|
|
* It's a shortcut to doing it yourself if you don't want to use
|
|
* the higher level functions.
|
|
*
|
|
* * `createSomeShapeVertices`
|
|
*
|
|
* These just create vertices, no buffers. This allows you to manipulate the vertices
|
|
* or add more data before generating a {@link module:twgl.BufferInfo}. Once you're finished
|
|
* manipulating the vertices call {@link module:twgl.createBufferInfoFromArrays}.
|
|
*
|
|
* example:
|
|
*
|
|
* var arrays = twgl.primitives.createPlaneArrays(1);
|
|
* twgl.primitives.reorientVertices(arrays, m4.rotationX(Math.PI * 0.5));
|
|
* var bufferInfo = twgl.createBufferInfoFromArrays(gl, arrays);
