  1. Hello, friends. There was such a task. Start up one! a wave over a sphere, which, as it were, looks like a map of the planet, which (map) in turn is generated from planeBufferGeometry and then these geometries are combined using THREE.BufferGeometryUtils.mergeBufferGeometries(geometries, false); Code of vertex shader: vertexShader:` varying vec2 vUv; uniform float time; void main(){ vUv=uv; vec3 newposition = position + position*sin(position.z*12.)*0.03; gl_Position = projectionMatrix * modelViewMatrix * vec4( newposition, 1. ); } `, The question is how to make only this one "wave", i.e. so that sin does not go over the entire sphere, but only in the middle, for example. And further. How can I change the direction of this "wave", now it comes from the Z coordinate of this sphere, I need it to go from the position I have defined (for example, approximate coordinates of London).
  2. My example shows how to use Planck.js with TypeScript in Debug and Release modes: hello-planckjs-webgl10-ts You should install these modules globally: npm i typescript -g npm i browserify -g npm i uglify-js -g Install all packages from `package.json` using the command: `npm i` Comment/Uncomment Debug/Release in `index.html` and `main.ts` (see comments in these files). Use these commands to build the example: `npm run debug` - to set breakpoint in code editors and to publish on PlayGround (like Plunker), for example: Hello Planck.js. WebGL 1.0, TypeScript `npm run release` - to bundle in `bundle.min.js` for production Note.

  4. hi, found regression with alpha12 version (works well, on 10 and 11). PBR metalines materials is almost black on galaxy 8+ with webgl 1.0 PG (dont know how to force webgl 1.0 in playground) looks like light or env texture is not applied here. could be some change in these components ? Phone: Galaxy 8+ OS: Android 7.0 Browser: Chrome 67.0.3396.87 WebGl: 1.0
  5. @Sebavan Hi, checked new examples of PBR , but found some issues. It doesn't work in safari mac, probably because it uses webgl1, works great in other browsers but they have webgl2. Example On safari sphere is just black. Dont get any errors just some warnings from webgl: [Log] BJS - [08:31:35]: Babylon.js engine (v3.0) launched (babylon.js, line 3) [Warning] WebGL: INVALID_OPERATION: texImage2D: type HALF_FLOAT_OES but ArrayBufferView is not NULL (babylon.js, line 5, x54) [Warning] WebGL: INVALID_FRAMEBUFFER_OPERATION: readPixels: attachment type is not correct for attachment (babylon.js, line 6) [Warning] WebGL: INVALID_FRAMEBUFFER_OPERATION: readPixels: attachment type is not correct for attachment (babylon.js, line 6) [Warning] WebGL: INVALID_FRAMEBUFFER_OPERATION: readPixels: attachment type is not correct for attachment (babylon.js, line 6) [Warning] WebGL: INVALID_FRAMEBUFFER_OPERATION: readPixels: attachment type is not correct for attachment (babylon.js, line 6) [Warning] WebGL: INVALID_FRAMEBUFFER_OPERATION: readPixels: attachment type is not correct for attachment (babylon.js, line 6) [Warning] WebGL: INVALID_FRAMEBUFFER_OPERATION: readPixels: attachment type is not correct for attachment (babylon.js, line 6) [Warning] WebGL: drawElements: texture bound to texture unit 0 is not renderable.
