Improve import export adding bundle build options with browserify, PWA Fully powered with static/dynamic cache , add to home page in same time fixed autoplay audio/video context construction.

Package Exports

  • matrix-engine

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (matrix-engine) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

About Matrix Engine project

Name: MATRIX-ENGINE 1.2.0

STATUS - [Integrated fully pwa addToHomePage/cache]

For npm users

Use starter project: https://github.com/zlatnaspirala/matrix-engine-starter

  • The benefits of this project is offering an overview of the entire application logic, easy native implementations (hybrid app), object structural. Thanks to Mr.Keestu i use (gl-program-structure) new version of glmatrix (2.0). Push&Pop matrix just like in opengles 1.1. First level of customisation is texture part of code. Best view in example custom_texture.js. I implemented webcam quick access call with custom active texture (porting canvas2d work to 3d faces)

Help for localhost dev stage

Switch example with url params

Code access:

const QueryString = matrixEngine.utility.QueryString;

Build Application bundle script

  • Before any operation install npm deps:
  npm i

@Note: If you use unsecured http protocol no build needed at all just navigate to the app.html. app.html load App.js like script type module. Same roles for all others instance build entries.

app-build.html , examples-build.html loads javascript type text/javascript. app.html , examples.html loads javascript type module.

  • Build entry App.js
  npm run build.app

Now navigate to the app-build.html page.

  • Build entry App-Examples.js
  npm run build.examples

Now navigate to the examples-build.html page.

  • Build just library
  npm run build.lib

Now navigate to the me-library.html page , represent empty page with loaded matrix-engine.

Custom textures

  App.scene.MySquareTexure1.custom.gl_texture = function ( object , t ) {

  world.GL.gl.bindTexture(world.GL.gl.TEXTURE_2D, object.textures[t] );
  world.GL.gl.texParameteri(world.GL.gl.TEXTURE_2D, world.GL.gl.TEXTURE_MAG_FILTER, world.GL.gl.LINEAR);
  world.GL.gl.texParameteri(world.GL.gl.TEXTURE_2D, world.GL.gl.TEXTURE_MIN_FILTER, world.GL.gl.LINEAR);
  world.GL.gl.texParameteri(world.GL.gl.TEXTURE_2D, world.GL.gl.TEXTURE_WRAP_S, world.GL.gl.CLAMP_TO_EDGE);
  world.GL.gl.texParameteri(world.GL.gl.TEXTURE_2D, world.GL.gl.TEXTURE_WRAP_T, world.GL.gl.CLAMP_TO_EDGE);

      world.GL.gl.texImage2D(
                    world.GL.gl.TEXTURE_2D,
                    0, // Level of details
                    world.GL.gl.RGBA, // Format
                    world.GL.gl.RGBA,
                    world.GL.gl.UNSIGNED_BYTE, // Size of each channel
                    object.textures[t].image
                    );

      world.GL.gl.generateMipmap(world.GL.gl.TEXTURE_2D);

  }

First person controller:

  //In one line activate also deactivate .
  App.camera.FirstPersonController = true;

  // Look in manifest.js

  camera : {
    viewAngle: 45,
    nearViewpoint: 0.1,
    farViewpoint: 1000,
    edgeMarginValue: 100,
    FirstPersonController: false
  }

Animated female droid:

  // LOAD MESH FROM OBJ FILES...
  // if you dont use obj or complex mesh you no need for this func
  // Must be improved loading sequences

  function onLoadObj(meshes) {

      App.meshes = meshes;
      OBJ.initMeshBuffers(world.GL.gl, App.meshes.female);
      OBJ.initMeshBuffers(world.GL.gl, App.meshes.female1);
      OBJ.initMeshBuffers(world.GL.gl, App.meshes.female2);

      OBJ.initMeshBuffers(world.GL.gl, App.meshes.female9);
      OBJ.initMeshBuffers(world.GL.gl, App.meshes.female10);

      OBJ.initMeshBuffers(world.GL.gl, App.meshes.female15);
      OBJ.initMeshBuffers(world.GL.gl, App.meshes.female16);
      OBJ.initMeshBuffers(world.GL.gl, App.meshes.female17);
      OBJ.initMeshBuffers(world.GL.gl, App.meshes.female18);

Blending:

  // Use it
  App.scene.female.glBlend.blendEnabled = true;
  App.scene.female.glBlend.blendParamSrc = ENUMERATORS.glBlend.param[4];
  App.scene.female.glBlend.blendParamDest = ENUMERATORS.glBlend.param[4];
  • Load Obj with UV map (Blender export tested):

For more details dee this example script: load_obj_file.js

Video texture:

world.Add("cubeLightTex" , 1 ,"TV" , textuteImageSamplers , App.meshes.TV );
App.scene.TV.streamTextures = new VIDEO_TEXTURE( "Galactic Expansion Fractal Morph [Official Video]" );

Camera texture:

  App.scene.TV.streamTextures = new ACCESS_CAMERA( "webcam_beta" );

Texture editor (runtime):

In examples : porting2d.js, porting_text.js, porting2d_particle.js you can found source code. It is very powerfull tool but you will need to use visual-js 2d canvas api part of project. Research 2dcanvas examples at: Online code snippet ( jsFiddle ) https://jsfiddle.net/user/zlatnaspirala/fiddles/

I put 2d program instance intro app/canvas2d folder. Than i use iframe for access and preview. Code for 2d program you can found at : app/canvas2d/starter/

To show/hide iframe use:

App.scene.outsideBox - is any object who have streamTextures LOADED with 2DCANVAS .

  App.scene.outsideBox.streamTextures.showTextureEditor()
  E('HOLDER_STREAMS').style.display = 'none';

Access to the canvas2d program:

  App.scene.outsideBox.streamTextures.iframe.contentWindow.

PWA Fully runned

Integrated Add to Home page and regular html5 page options. In same time fixed all autoplay audio and video context construction. It is good to consult pwa test on page. Best way is to keep it on 100% pass. pwa-powered
