Module: points/image

These are wgsl functions, not js functions. The function is enclosed in a js string constant, to be appended into the code to reference it in the string shader.

Members

staticconstantdecodeNumberSprite String

From a provided number, get the sprite in an atlas that matches the value.

Source:: core/image.js, line 203

Example

import { decodeNumberSprite } from 'points/image';

// wgsl string
${decodeNumberSprite}
let value = decodeNumberSprite(numberToDecode, start0char, image, position, startPosition, uvr, ratio, size);js

staticconstantflipTextureUV String

Flips texture in Y. This because it comes flipped, so this corrects it.

Source:: core/image.js, line 118

Example

import { flipTextureUV } from 'points/image';

// wgsl string
${flipTextureUV}
let value = flipTextureUV(uvr);js

staticconstantpixelateTexture String

Increase the aparent pixel size of the texture image using textureSample. This reduces the quality of the image.

Source:: core/image.js, line 251

Example

import { pixelateTexture } from 'points/image';

// wgsl string
${pixelateTexture}
let value = pixelateTexture(image, imageSampler, 10,10, uvr);js

staticconstantpixelateTexturePosition String

Increase the aparent pixel size of the texture image using texturePosition. This reduces the quality of the image.

Source:: core/image.js, line 282

Example

import { pixelateTexturePosition } from 'points/image';

// wgsl string
${pixelateTexturePosition}
let value = pixelateTexturePosition(image, imageSampler, vec2f(), 10,10, uvr);js

staticconstantsprite String

Sprite or Atlas. Extract a piece of the sprite with an index.

Source:: core/image.js, line 143

Example

import { sprite } from 'points/image';

// wgsl string
${sprite}
let value = sprite(texture, imageSampler, vec2f(), uvr, 0, vec2(8u,22u) );js

staticconstanttextureExternalPosition String

Places texture_external in a position. Texture external being in this case a video loaded as texture in the JS side.

Source:: core/image.js, line 76

Example

import { textureExternalPosition } from 'points/image';
await points.setTextureVideo('video', 'myvideo.mp4');

// wgsl string
${textureExternalPosition}
let value = textureExternalPosition(video, imageSampler, vec2f(), uvr, true);js

staticconstanttexturePosition String

Places texture in a position. The texture being an image loaded from the JS side.

Source:: core/image.js, line 28

Example

import { texturePosition } from 'points/image';

await points.setTextureImage('image', 'myimage.jpg');

// wgsl string
${texturePosition}
let value = texturePosition(image, imageSampler, vec2f(), uvr, true);js
