Class UnstructGridModel

It handles surface elements with any number of nodes. A model has one or more States, which links a Geometry to scalar, displacement and transformation results for that geometry in that state.

Here is a simple example of how to create an usg model containing a single quad element with a per node scalar result in one state:

let model = new cee.usg.UnstructGridModel();
this.m_view.addModel(model);

let geometry = new cee.usg.Geometry();
let part = geometry.addPart();

// Create a single quad mesh
const nodeArr = [0,0,0, 1,0,0, 1,1,0, 0,1,0];
const elConnArr = [0,1,2,3];
part.mesh = new cee.usg.Mesh(nodeArr, 4, elConnArr);

// Configure the visual appearance of the part
part.settings.color = new cee.Color3(1,0,0);
part.settings.drawStyle = cee.usg.DrawStyle.SURFACE_MESH

// Create a state, set the geometry and add the scalar result
let state = model.addState();
state.geometry = geometry;

let scalarArr = [1,2,3,4];
state.setPartFringesAt(0, new cee.usg.PartScalars(cee.usg.ResultMapping.PER_NODE, scalarArr));

// Configure the mapper to use, and
const mapper = new cee.ScalarMapperFilledContoursUniform();
mapper.colorArray = cee.ColorTableFactory.color4TableArray(cee.ColorTable.NORMAL, 15);
mapper.setRange(1,4);
model.fringesSettings.scalarMapper = mapper;

// Add a color legend based on the mapper
this.m_view.overlay.addCustomColorLegendForScalarMapper(mapper, "Demo result", 1);
