JSPM – matrix-engine@1.0.4

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`

Version 1.0.4

STATUS - [NPM FIRST INTEGRATION - BETA]

For npm users

npm i matrix-engine

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)

Adding color pyramyde
Adding color square
Adding color triangle

Custom texture
First Person controller

We just override function for texture executing code. Next level is full custom opportunity , geometry , collision , networking etc.

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.female3);
      OBJ.initMeshBuffers(world.GL.gl, App.meshes.female4);
      OBJ.initMeshBuffers(world.GL.gl, App.meshes.female5);
      OBJ.initMeshBuffers(world.GL.gl, App.meshes.female6);
      OBJ.initMeshBuffers(world.GL.gl, App.meshes.female7);
      OBJ.initMeshBuffers(world.GL.gl, App.meshes.female8);
      OBJ.initMeshBuffers(world.GL.gl, App.meshes.female9);
      OBJ.initMeshBuffers(world.GL.gl, App.meshes.female10);
      OBJ.initMeshBuffers(world.GL.gl, App.meshes.female11);
      OBJ.initMeshBuffers(world.GL.gl, App.meshes.female12);
      OBJ.initMeshBuffers(world.GL.gl, App.meshes.female13);
      OBJ.initMeshBuffers(world.GL.gl, App.meshes.female14);
      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);

      textuteImageSamplers2 = {

        mix_operation : "multiply",

      setTimeout( function() {

        var animation_construct = {

            currentAni : 0 ,
            speed : 3
        };

        world.Add("obj" , 1 ,"female" , textuteImageSamplers2 , App.meshes.female , animation_construct );

        App.scene.female.position.y = -3;
        App.scene.female.rotation.rotationSpeed.z = 20;
        App.scene.female.position.z = -13;

      },100)

  }

  OBJ.downloadMeshes({

    'female18': 'res/3d-objects/female/female_000037.obj',
  } , onLoadObj  );

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

It is good to consult pwa test on page. Best way is to keep it on 100% pass. pwa-powered
