Work with the interface
Added buttons for creating primitives from the threejs library, the creation of which I plan to implement.
To do this, I created an array of objects with a description of my buttons, containing the text for the button, the type of geometry being created for transmission to TA_Enteties and a link to the icon:
let primitivesNamesForButtons = [ {text:'Box', type: 'BoxBufferGeometry', imgLink: './ico/cubeico.PNG'}, {text:'Sphere', type: 'SphereBufferGeometry', imgLink: './ico/sphereico.PNG'}, {text:'Circle', type: 'CircleBufferGeometry', imgLink: ''}, {text:'Cone', type: 'ConeBufferGeometry', imgLink: ''}, {text:'Cylinder', type: 'CylinderBufferGeometry', imgLink: ''}, {text:'Dodecahedron', type: 'DodecahedronBufferGeometry', imgLink: ''}, {text:'Icosahedron', type: 'IcosahedronBufferGeometry', imgLink: ''}, {text:'Octahedron', type: 'OctahedronBufferGeometry', imgLink: ''}, {text:'Plane', type: 'PlaneBufferGeometry', imgLink: ''}, {text:'Ring', type: 'RingBufferGeometry', imgLink: ''}, {text:'Shape', type: 'ShapeBufferGeometry', imgLink: ''}, {text:'Tetrahedron', type: 'TetrahedronBufferGeometry', imgLink: ''}, {text:'Text', type: 'TextBufferGeometry', imgLink: ''}, {text:'Torus', type: 'TorusBufferGeometry', imgLink: ''}, {text:'TorusKnot', type: 'TorusKnotBufferGeometry', imgLink: ''}, {text:'Tube', type: 'TubeBufferGeometry', imgLink: ''} ]
Through forEach I add them all to the buttonsDiv:
primitivesNamesForButtons.forEach(element => { taUI.addElement( buttonsDiv, 'button', element.text, element.imgLink, function () { taScene.mode.action = 'creationEntity'; taScene.mode.entity = element.type; } ); });
Added a display of material parameters in the options menu.
I made the Main menu hidden when I click on the arrow:
let hideButton = document.createElement( 'div'); hideButton.className = 'hideButton'; hideButton.id = 'hideButton'; hideButton.innerHTML = '&#9668'; mainToolbar.style.left = '0px'; hideButton.addEventListener( 'click', (e) => { if (mainToolbar.style.left === '0px') { requestAnimationFrame( function moveAnim (){ let pos = mainToolbar.style.left.replace('px',''); pos -= 10; mainToolbar.style.left = pos + 'px'; if (mainToolbar.style.left.replace('px','') > -250) { hideButton.innerHTML = '&#9658'; requestAnimationFrame(moveAnim); } } ); } else { mainToolbar.style.left = '0px'; hideButton.innerHTML = '&#9668'; } } ) mainToolbar.appendChild( hideButton);
Implemented the creation of a circle. At the same time, I ran into a problem. Threejs issued a warning in the console with each render:
three.js: 2533 THREE.Matrix3: .getInverse () can’t invert matrix, determinant is 0.
It turned out that it is impossible for the object to have a zero value (for example, height) or scale. In my case, the warning worked on creating a BoundingBox, since the circle is a flat object and the height is 0. I had to add a check:
if ( box.box.min.z === 0) { box.box.min.z = -0.001; box.box.max.z = 0.001; }
