Update the specified isosurface. This method must be called on the MCT. Use QueuedTask.Run.
How to Change Value and Color on an Isosurface
//var voxelLayer = ... ;
//Must be on the QueuedTask.Run()
var variable = voxelLayer.SelectedVariableProfile;
//Change the color of the first surface for the given profile
var surface = variable.GetIsosurfaces().FirstOrDefault();
if (surface != null)
{
if (voxelLayer.Visualization != VoxelVisualization.Surface)
voxelLayer.SetVisualization(VoxelVisualization.Surface);
//Change the iso surface voxel value
surface.Value = surface.Value * 0.9;
//get a random color
var count = new Random().Next(0, 100);
var colors = ColorFactory.Instance.GenerateColorsFromColorRamp(
((CIMVoxelStretchRenderer)variable.Renderer).ColorRamp, count);
var idx = new Random().Next(0, count - 1);
surface.Color = colors[idx];
//set the custom color flag true to lock the color
//locking the color prevents it from being changed if the
//renderer color range or color theme is updated
surface.IsCustomColor = true;
//update the surface
variable.UpdateIsosurface(surface);
}
Change Isourface Color Back to Default
//var voxelLayer = ... ;
//Must be on the QueuedTask.Run()
//var variable = ...;
//var surface = ...;
if (surface.IsCustomColor)
{
surface.Color = variable.GetIsosurfaceColor((double)surface.Value);
surface.IsCustomColor = false;
//update the surface
variable.UpdateIsosurface(surface);
}
