Geometry types
| Note |
|---|
Note: Objects with geometry types "mesh" or "meshblob" can be written into BIM+ database. Geometry type "threejs" optimized for viewing on mobile devices or in browser and can not be written to the database directly. |
Mesh type
| Code Block |
|---|
mesh: {
colors: 4291993670,
vertices: [ 96.149, 179.546, ... ],
faces: [ 4,0,1,2,3, 3,4,5,6, ... ]
}
where:
color: array of decimal RGBA values;
vertices: plain array of 3D vertices coordinates like [x0, y0, z0, x1, y1, z1, ...]
faces: plain array of faces definitions like first number is quantity of vertices, than vertex indices list, see example.

Mesh BLOB type
This type generally compressed mesh format intended to be used in the desktop CAD applications. Internal CAD format of the geometry with help of client side C# DLL will be converted into BIM+ mesh format (described above) and compressed (z.b. with ZIP) in order to get smaller JSON size. In this case JSON objects looks like:
| Code Block |
|---|
meshblob: "d273f7a6a7d8f8725484fe6282..."
|
TreeJS type
as mentioned above this format is optimized for viewing on mobile devices or in browser. Native model will be filtered and tessellated in order to deliver minimal JSON size and maximal navigation speed (FPS). This model has ThreeJS JSON v 3.1 format and can be directly parsed by the client. JSON object in this case looks like:
| Code Block |
|---|
threejs: {
elementcount: 14312,
viewbox: {
x: 827364,
y: 23765,
z: 2974652,
with: 827346,
height: 2873456,
depth: 1726354
},
colors: [123414, 9817413, ....],
geometries: [ {<ThreeJS_JSON_format>}, {...}, ... ]
}
