here is my code
FlutterMap(
mapController: mapController,
options: MapOptions(
controller: mapController,
center: LatLng(33.680088056393814, 72.7987044426807),
zoom: 14,
maxZoom: 18,
onTap: (p, k) {
final bounds = mapController.bounds;
var a = mapController;
var sw = epsg3413CRS.projection.project(bounds.southWest!);
var ne = epsg3413CRS.projection.project(bounds.northEast!);
print('Map bounds:sw.x: ${sw.x},${sw.y},${ne.x},${ne.y}');
},
),
layers: layerz,
),
i have search alot but after too much effort i only got BBOX for api. but other parameters are remaining x, y, height, width etc

I am trying to add a 3D text over the BoxGeometry sides for front, right, left and top.
I implmented this code as below :
loadFont = () =>{
const loader = new THREE.FontLoader();
loader.load( 'https://threejs.org/examples/fonts/helvetiker_regular.typeface.json', function ( response ) {
console.log("response "+response);
return response;
} );}
createText = () => {
let font = this.loadFont();
this.textGeo = new THREE.TextGeometry( "Hello", {
font: font,
size: 70,
height: 20,
curveSegments: 4,
bevelThickness: 2,
bevelSize: 1.5,
bevelEnabled: true
});
const materials = [
new THREE.MeshPhongMaterial( { color: 0xffffff, flatShading: true } ), // front
new THREE.MeshPhongMaterial( { color: 0xffffff } ) // side
];
this.textMesh1 = new THREE.Mesh(this.textGeo, materials );
this.textMesh1.position.y = 80;
this.textMesh1.position.z = 0;
this.textMesh1.rotation.x = 0;
this.textMesh1.rotation.y = Math.PI * 2;
this.scene.add(this.textMesh1);
this.root.add(this.textMesh1);
I am not able to receive a 3D text in my scene?
Getting Error - "THREE.TextGeometry: font parameter is not an instance of THREE.Font."
When I try using
const loader = new FontLoader();
this.textGeo = new TextGeometry( "Hello", {
font: font,
size: 70,
height: 20,
curveSegments: 4,
bevelThickness: 2,
bevelSize: 1.5,
bevelEnabled: true
});
I don't get exact place from where I am required to import these FontLoader and TextGeometry classes.
Any help, guidance or reference would be helpful. Thanks
TextGeometry and FontLoader have been moved out of the core some time ago so you have to import them from three/examples/jsm/geometries/TextGeometry.js and three/examples/jsm/loaders/FontLoader.js.
Next, the following line of code does not work since loadFont() actually works asynchronous:
let font = this.loadFont();
loadFont() will always return undefined since you return the font in the onLoad() callback function of FontLoader.load(). You have to rewrite your listing to account for the asynchronous nature of the code flow.
As I understand I have to use one canvas for both mapbox Gl and p5.
But how to do this? And what if I have p5 animation will it overwrite the canvas with map?
Any example or hint? Thanks.
My code, but nothing serious
mapboxgl.accessToken = 'pk.***';
var mapGL = new mapboxgl.Map({
container: 'map',
style: 'mapbox://styles/mapbox/light-v9',
center: [-120.36603539685188, 50.68667605749022],
zoom: 11.6
});
var mainCanvas;
function setup() {
mainCanvas = createCanvas(720, 400, WEBGL);
}
function draw() {
background(102);
rotate(frameCount / 100.0);
rect(30, 20, 25, 25);
}
Different drawing libraries don't usually play nice with each other on the same canvas. You could try something like overlaying the P5.js canvas on top of the mapbox canvas.
Better yet, use a map library that's already compatible with P5.js, like Mappa or p5.tiledmap. That allows you to draw a map inside P5.js, which makes drawing on top of it much easier.
This is a very old question, but for whoever revisits this question looking for an option... nowadays this could be easily done with the latest version of threebox and a few lines of code. The result looks like this:
<script>
mapboxgl.accessToken = 'pk.eyJ1IjoianNjYXN0cm8iLCJhIjoiY2s2YzB6Z25kMDVhejNrbXNpcmtjNGtpbiJ9.28ynPf1Y5Q8EyB_moOHylw';
var origin = [2.294514, 48.857475];
var map = new mapboxgl.Map({
container: 'map',
style: 'mapbox://styles/mapbox/satellite-v9',
center: origin,
zoom: 18,
pitch: 60,
bearing: 0
});
map.on('style.load', function () {
map
.addLayer({
id: 'custom_layer',
type: 'custom',
renderingMode: '3d',
onAdd: function (map, mbxContext) {
window.tb = new Threebox(
map,
mbxContext,
{
defaultLights: true,
}
);
// import tower from an external glb file, downscaling it to real size
// IMPORTANT: .glb is not a standard MIME TYPE, you'll have to add it to your web server config,
// otherwise you'll receive a 404 error
var options = {
obj: '/3D/eiffel/eiffel.glb',
type: 'gltf',
scale: 0.01029,
units: 'meters',
rotation: { x: 0, y: 0, z: 0 }, //default rotation
adjustment: { x: -0.5, y: -0.5, z: 0 } // place the center in one corner for perfect positioning and rotation
}
tb.loadObj(options, function (model) {
model.setCoords(origin); //position
model.setRotation({ x: 0, y: 0, z: 45.7 }); //rotate it
tb.add(model);
})
},
render: function (gl, matrix) {
tb.update();
}
});
})
</script>
I'm trying to show an icon on the center of a circle.
Here is my code :
jsFiddle : http://jsfiddle.net/61dkv8tr/2/
(function(){
var base64img = "data:image/gif;base64,R0lGODlhPQBEAPeoAJ[...]==";
var extent = [0, 0, 400, 400];
var sourceV = new ol.source.Vector({ wrapX: false });
var map = new ol.Map({
renderer: 'canvas',
target: 'divMap',
layers: [
new ol.layer.Vector({
source: sourceV
})
],
restrictedExtent: extent,
view: new ol.View({
center: ol.extent.getCenter(extent),
extent: extent, //world limit drag map
resolution : 1
})
});
var radius = 50;
var x = 200;
var y = 200;
var circleGeom = new ol.geom.Circle([x, y], radius);
var feature = new ol.Feature(circleGeom);
feature.setStyle(new ol.style.Style ({
stroke: new ol.style.Stroke({
color: 'black',
width: 1
}),
image: new ol.style.Icon({
src: base64img,
color: '#4271AE',
crossOrigin: 'anonymous',
})
}));
sourceV.addFeature(feature);
})();
The render is just the stroke of the circle. Do I miss something ?
The icon is a small red bus.
PS : I also tried with a relative URL, an absolute URL, a canvas...
Thanks !
OK I found the solution. style.Icon only works if its property 'geometry' is of type geom.Point (or if the feature owns a point as geometry type).
To get around with any type of geometry I use the method getExtent() to calculate the center of the geometry and I create a new one of type Point.
when you drag images you can control their moving with dragBoundFunc. Is there something similar when you scaling? I want to set an image area in "part of a stage" and when i setScale for this image and make it bigger, i don't want to see parts which is bigger than image area i've set before. is it possible? Here is my fiddle..
var stage = new Kinetic.Stage({
container : 'canvas',
width : 620,
height : 236
});
var layer = new Kinetic.Layer();
var leftImage = new Image();
leftImage.src = "http://www.html5canvastutorials.com/demos/assets/darth-vader.jpg";
var leftImg = new Kinetic.Image({
x : stage.getWidth() - 480,
y : stage.getHeight() - 126,
image : leftImage,
width : 190,
height : 124,
offset : [95, 62],
draggable : true,
dragBoundFunc: function(pos) {
var x=stage.getWidth() - 480;
var y=stage.getHeight() - 126;
var radius = 50;
var scale = radius/ Math.sqrt(Math.pow(pos.x - x, 2) + Math.pow(pos.y - y, 2));
if(scale < 1)
return {
y: Math.round((pos.y - y) * scale + y),
x: Math.round((pos.x - x) * scale + x)
};
else
return pos;
}
});
var rectLeft = new Kinetic.Rect({
x : 38,
y : 20,
width : 232,
height : 184,
stroke:'red',
listening:false
});
var rectRight = new Kinetic.Rect({
x : 350,
y : 20,
width : 232,
height : 184,
stroke:'green',
listening:false
});
layer.add(leftImg);
layer.add(rectLeft);
layer.add(rectRight);
stage.add(layer);
document.getElementById('larger').addEventListener('click', function() {
leftImg.setScale(leftImg.getScale().x + 1.5);
layer.draw();
}, false);
Sure.
You can clip your scaled image into a fixed area of the stage by wrapping your image in a group and setting the clip property of that group to your fixed area.
If you set the clip property on a group like this:
var group=new Kinetic.Group({
x:100,
y:100,
width: originalImageWidth,
height: originalImageHeight,
clip: [0,0,originalImageWidth,originalImageHeight]
});
Then the image you put in the group will be clipped to stage #100,100 and size == original image size.
If you later scale the image larger, the clipping area will act as a "viewport" into part of the larger image.
I have a problem an hope to find any solution for it.
I am using Kinetic.js to create a HMI solution with special look-and-feel. Therefor I have created a function that creates 3 layers for a stage: a background layer with a grid, a layer with static shapes for the base layout of the HMI-screen and the third layer for all interactive elements (like buttons, valuedisplays and so on...). Now I want to cache the grid and the static layer to improve performance, because this layers will never change until the whole HMI-screen will change...
As a test I started to code the caching for the grid layer using the following code:
// Create a grid layer if showGrid is set to TRUE...
console.log('Start to create background grid if required');
if (this.actualPageConfig.showGrid) {
var grid = new Kinetic.Layer();
for (var x=1; x <= this.cols; x++) {
var eLoc = LCARSElements.posToRealPos(x, 1, this.cols, this.rows);
if (x <= this.actualPageConfig.columns) {
grid.add(new Kinetic.Line({
points: [eLoc.x, eLoc.y, eLoc.x, eLoc.height],
stroke: "red",
strokeWidth: 1,
lineCap: "round",
lineJoin: "round"
}));
}
}
for (var y=1; y <= this.rows; y++) {
var eLoc = LCARSElements.posToRealPos(1, y, this.cols, this.rows);
if (y <= this.actualPageConfig.rows) {
grid.add(new Kinetic.Line({
points: [eLoc.x, eLoc.y, eLoc.width, eLoc.y],
stroke: "red",
strokeWidth: 1,
lineCap: "round",
lineJoin: "round"
}));
}
}
// Add grid layer to stage
//this.stage.add(grid); <-- to be replaced by cache image
// Convert grid into an image and add this to the stage
console.log('convert grid to image to increase performance');
grid.toImage({
width: displayManager.stage.getWidth(),
height: displayManager.stage.getHeight(),
callback: function(img) {
var cacheGrid = new Kinetic.Image({
image: img,
x: 0,
y: 0,
width: displayManager.stage.getWidth(),
height: displayManager.stage.getHeight()
});
console.log('insert grid-image to stage');
displayManager.stage.add(cacheGrid);
console.log('redraw stage...');
displayManager.stage.draw();
}
});
}
My problem is, that's not working. The grid is not visible any more and the console log shows the following error information:
Type error: layer.canvas is undefined
layer.canvas.setSize(this.attrs.width, this.attrs.height); kinetic.js (Zeile 3167)
As I already figured out the error rise when the code "displayManger.stage.add(cacheGrid) will be executed (displayManager is the outside-class where this code snipped reside).
Can anyone see where I made the mistake? When I directly add the layer grid anything works fine...
I have created a jsfiddle to demonstrate the problem: jsfiddle
In fiddle you can run both versions by changing one parameter. Hope this helps....
Thanks for help.
Best regards

Actually, the problem is simpler than you might think - after caching the layer into an image, you're trying to add an image object directly to the stage (you can't do that).
To fix the problem, you need to create a new layer, say cahcedLayer, add the image to cachedLayer, and then add cachedLayer to the stage.

I've made this test and it worked. First, I draw 1000 squares to a layer, add this layer to a hidden stage then make an image from this stage using stage.toDataURL(). When the callback returns, I just create an Image from the data and a Kinetic.Image from the Image. Then I add it to a layer on my main (visible) stage.
Code (be sure to have a div called 'invisible'):
window.onload = function()
{
var stage = new Kinetic.Stage({
width: 520,
height: 480,
container: 'container'
});
var outerStage = new Kinetic.Stage({
width: stage.getWidth(),
height: stage.getHeight(),
container: 'invisible'
});
var layerToCache = new Kinetic.Layer();
var layer = new Kinetic.Layer();
var group = new Kinetic.Group({offset: [stage.getWidth(), stage.getHeight()]});
var anim = new Kinetic.Animation(function(frame){
group.rotate(0.02);
}, layer);
var fills = ['red', 'green', 'blue', 'orange', 'purple', 'cyan',
'black', 'brown', 'forestgreen', 'gray', 'pink'];
for (var i = 0; i < 10000; ++i)
{
(function ()
{
var size = Math.random() * 60 + 20;
var square = new Kinetic.Rect({
width: size,
height: size,
fill: fills[i % fills.length],
x: Math.random() * stage.getWidth() - 20,
y: Math.random() * stage.getHeight() - 20
});
layerToCache.add(square);
})();
}
var squaresImg = new Kinetic.Image();
outerStage.add(layerToCache);
outerStage.toDataURL({
callback: function (dataURL){
outerStage.clear();
var img = new Image();
img.src = dataURL;
img.onload = function () {
squaresImg.setImage(img);
squaresImg.setX(squaresImg.getWidth() >> 1);
squaresImg.setY(squaresImg.getHeight() >> 1);
group.setX(stage.getWidth() >> 1);
group.setY(stage.getHeight() >> 1);
group.add(squaresImg);
layer.add(group);
layer.draw();
anim.start();
}
}
});
var div = document.getElementById('invisible');
div.parentNode.removeChild(div);
stage.add(layer);
}
