Example Base3D

«    »

3d applications can be created by extending hxd.App and then you can attach meshes to s3d, which is the root scene for 3d.

import h3d.scene.*;

class Base3D extends SampleApp {

  var time : Float = 0.;
  var obj1 : Mesh;
  var obj2 : Mesh;

  override function init() {
    super.init();

    // creates a new unit cube
    var prim = new h3d.prim.Cube();

    // translate it so its center will be at the center of the cube
    prim.translate( -0.5, -0.5, -0.5);

    // unindex the faces to create hard edges normals
    prim.unindex();

    // add face normals
    prim.addNormals();

    // add texture coordinates
    prim.addUVs();

    // accesss the logo resource and convert it to a texture
    var tex = hxd.Res.hxlogo.toTexture();

    // create a material with this texture
    var mat = h3d.mat.Material.create(tex);

    // our first cube mesh on the 3D scene with our created material
    obj1 = new Mesh(prim, mat, s3d);

    // creates another cube, this time with no texture
    obj2 = new Mesh(prim, s3d);

    // set the second cube color
    obj2.material.color.setColor(0xFFB280);

    // put it above the first cube
    obj2.z = 0.7;

    // scale it down to 60%
    obj2.scale(0.6);

    // adds a directional light to the scene
    var light = new h3d.scene.DirLight(new h3d.Vector(0.5, 0.5, -0.5), s3d);
    light.enableSpecular = true;

    // set the ambient light to 30%
    s3d.lightSystem.ambientLight.set(0.3, 0.3, 0.3);

    // disable shadows
    obj1.material.shadows = false;
    obj2.material.shadows = false;
    
    if (engine.driver.hasFeature(Wireframe)) {
      addCheck("Wireframe", function() { return obj2.material.mainPass.wireframe; }, function(v) { obj2.material.mainPass.wireframe = v; });
    }
  }

  override function update( dt : Float ) {

    // time is flying...
    time += 0.6 * dt;

    // move the camera position around the two cubes
    var dist = 5;
    s3d.camera.pos.set(Math.cos(time) * dist, Math.sin(time) * dist, dist * 0.7 * Math.sin(time));

    // rotate the second cube along a given axis + angle
    obj2.setRotationAxis(-0.5, 2, Math.cos(time), time + Math.PI / 2);
  }

  static function main() {

    // initialize embeded ressources
    hxd.Res.initEmbed();

    // start the application
    new Base3D();
  }

}
