.vertices array does not give the vertices in THREE.js

由 丶灬走出姿态 提交于 2019-12-11 04:49:16
问题 I am using OBJloader to load an .obj file in WEBGL , Three.js. I want to access the vertices and faces of the objects but the geometry.vertices does not return the vertices positions and it gives me undefined. Here is a piece of code: var tool= new THREE.OBJLoader(); tool.load( '../obj/tool.obj', function ( object ) { var material = new THREE.MeshLambertMaterial({color:0xA0A0A0}); object.traverse( function ( child ) { if ( child instanceof THREE.Mesh ) { child.material = material; console.log

List all registered routes in Vertx

由 情到浓时终转凉″ 提交于 2019-12-10 21:26:01
问题 Is there any way (like in a symfony application) to list down all the available/register routes on a vertx server? I am facing an issue that my registered route is returning a 404 on running restassure tests. 回答1: Yes, but you have to write a bit of code to achieve that. // Example router setup Router router = Router.router(vertx); router.route(HttpMethod.GET, "/").handler(routingContext -> { routingContext.response().end("Root"); }); router.route(HttpMethod.GET, "/users").handler

OpenGL: Are VAOs and VBOs practical for large polygon rendering tasks?

问题 If you wanted to render a large landscape with thousands of polygons in the viewing frustum at a time as well as the user's viewpoint changing constantly, is it practical to use VAOs or VBOs? I mean, every time the player's position or camera rotation changed, you would have to recompute the vertex data in order to properly cull any vertices or scenes which are no longer seen in order to keep a good FPS count. But in doing this, your FPS count would go down because you are, well, repacking

Find Corners of Rectangle, Given Plane equation, height and width

由 江枫思渺然 提交于 2019-12-07 15:11:41
问题 Essentially I want to make a rectangular plane face an object at all times. 1) I have found my plane equation (ax + by + cz + d = 0) 2) I have the center point of the rectangle (P0 = (x0,y0,z0)), which lays on the plane. 3) I have the width and Height of the rectangle. (W, H) 4) I know that the top two corners of the rectangle will have equal Y values, this goes for bottom 2 corners also. (Y is my up and down axis, the rectangle top and bottom lines will always be parallel to the x,z plane)

draw texture in OpenGL Android from 0,0 coordinates

问题 I'm new to opengGL and excuse if the questions are too naive. I'm going through some tuturials for seeking help on learning this. I have a small program written where i'm drawing a texture on a GLSurfaceView. I want to draw a number of textures(bitmap images) in a sequential order starting from 0,0 coordinates. Also I need some gap in images on the screen. Please help. Do I need to change the positioning of vertices buffer. please suggest. Here is my renderer Code. public class GlRenderer

Cube with triangle strips and vector normals in openGL

由 偶尔善良 提交于 2019-12-06 14:21:33
问题 I'm trying to create a cube using one series of vertices such as attempted in this example (which I believe is wrong) and also talked about on this forum. The answer I'm looking for should look something like this: 1, 1, -1 -1, -1, -1, 1, 1, 1 ... and so on. I'm hoping to get this down to a minimum of 13 vertices (6 sided cube = 12 triangles). Is this possible? 回答1: There's little benefit in minimizing the vertices of a triangle / quad strip. One advantage of having each face has its own

Three.js shape from random points

由 纵饮孤独 提交于 2019-12-04 19:30:21
I have a N number of random points (in this case 20), with a X,Y and Z constrains. How can I create ANY (preferably closed) shape (using Three.js library) , given and starting only from N random points. There are probably many variants, please share yours. var program = new Program(reset,step) program.add('g',false) function reset() { scene.clear() scene.add(new THREE.GridHelper(100,1)) } function step() { } program.startup() var numpoints = 20; var dots = []; //If you want to use for other task for (var i = 0 ; i < numpoints ; i++){ var x = Math.random() * (80 - 1) + 1 //Math.random() * (max
