BIMSurfer is a WebGL-based 3D viewer for BIMServer that's built on xeoEngine.
TODO: More info
Creating a BIMSurfer:
var bimSurfer = new BimSurfer({
domNode: "viewerContainer"
});Loading a model from BIMServer:
bimSurfer.load({
bimserver: ADDRESS,
username: USERNAME,
password: PASSWORD,
poid: 131073,
roid: 65539,
schema: "ifc2x3tc1" // < TODO: Deduce automatically
})
.then(function (model) {
// Model is now loaded and rendering.
// The following sections show what you can do with BIMSurfer at this point.
//...
});Generate a random test model if you want to test BIMSurfer without loading anything from BIMServer:
bimSurfer.loadRandom();The following usage examples in this guide will refer to objects from the generated test model.
Selecting four objects:
bimSurfer.setSelection({ids: ["object3", "object2", "object4", "object6"], selected: true });then querying which objects are selected:
bimSurfer.getSelection()The result shows that those four objects are currently selected:
["object3", "object2", "object4", "object6"]If we then deselect two objects, then query the selection again:
bimSurfer.setSelection({ids: ["object3", "object6"], selected: false });
bimSurfer.getSelection()The result shows that only two objects are now selected:
["object2", "object4"] Subscribing to selection updates:
bimSurfer.on("selection-changed",
function() {
var selected = bimSurfer.getSelection();
console.log("selection = " + JSON.stringify(selected));
});Hiding three objects by ID:
bimSurfer.setVisibility({ids: ["object3", "object1", "object6"], visible: false });Setting two objects visible by ID:
bimSurfer.setVisibility({ids: ["object1", "object6"], visible: true });Hiding all objects of IFC types "IfcSlab" and "IfcWall":
bimSurfer.setVisibility({types: ["IfcSlab", "IfcWall"], visible: false });Making two objects pink:
bimSurfer.setColor({ids: ["object3", "object6"], color: [1, 0, 1] })An optional fourth element may be specified in the color to set opacity:
bimSurfer.setColor({ids: ["object3", "object6"], color: [1, 0, 1, 0.5] })Setting the camera position:
bimSurfer.setCamera({
eye: [-20,0,20],
target: [0,10,0],
up: [0,1,0]
});Then "target" will then be the position we'll orbit about with the mouse or arrow keys (until we double-click an object to select a different orbit position).
Setting the camera projection to orthographic:
bimSurfer.setCamera({
type:"ortho"
});Setting the view volume size for orthographic, switching to orthographic projection first if necessary:
bimSurfer.setCamera({
type:"ortho",
scale: 100
});This uses the same technique as Blender, where the scale argument relates to the "real world" size of the model, meaning that if you set scale to 100, then your view would at most encompass an element of 100 units size.
Setting the camera projection to perspective:
bimSurfer.setCamera({
type:"persp"
});Setting the FOV on Y-axis for perspective, switching to perspective projection first if necessary:
bimSurfer.setCamera({
type:"persp",
fovy: 65
});Querying camera state:
var camera = bimSurfer.getCamera();The returned value would be:
{
"type": "persp",
"eye": [-20,0,20],
"target": [0,10,0],
"up": [0,1,0],
"fovy": 65
}Subscribing to camera updates:
bimSurfer.on("camera-changed",
function() {
var camera = bimSurfer.getCamera();
console.log(JSON.stringify(camera));
});Flying the camera to fit the specified objects in view:
bimSurfer.viewFit({ ids: ["object3", "object1", "object6"], animate: true });Jumping the camera to fit the specified objects in view:
bimSurfer.viewFit({ids: ["object1", "object6"], animate: false });Flying to fit all objects in view:
bimSurfer.viewFit({ animate: true });Jumping to fit all objects in view:
bimSurfer.viewFit({ animate: false });Resetting the camera to initial position:
bimSurfer.reset({ cameraPosition: true });Resetting all objects to initial visibilities:
bimSurfer.reset({ visibility: true });Resetting two objects to their initial visibilities:
bimSurfer.reset({ ids: ["object3", "object6"], visibility: true });Resetting all objects to their initial colors:
bimSurfer.reset({ elementColors: true });Resetting two objects to their initial colors:
bimSurfer.reset({ ids: ["object3", "object6"], elementColors: true });Deselecting all objects:
bimSurfer.reset({ selectionState: true });
