Optional colorAn expression to specify what colors to apply to mesh data.
To create expressions, you must use the factory methods in the ExpressionFactory module. The expression must be well-formed and resolve to a color value. If you want to update the styling very often, consider using parameters in your expression. Changing the values of parameters is more efficient than replacing the whole expression. If you define a colorExpression, the texture data, if any, will not be displayed. The color expression will determine the color. Note that the alpha component of the color is ignored so the color will be fully opaque, unless you enable TileSet3DLayer.transparency.<code>null</code> If not set, the mesh will use the texture data of the mesh, if any.
Optional displacementAn expression to displace mesh data.
To create expressions, you must use the factory methods in the ExpressionFactory module. The expression must be well-formed and resolve to a point value.If you want to update the styling very often, consider using parameters in your expressions. Changing the values of parameters is more efficient than replacing the whole expression.
// Example of a displacement expression that pushes down everything inside a shape.
var _ = ExpressionFactory;
var shape = _.orientedBox(layer.orientedBox);
meshStyle.displacementExpression = _.pushDown(shape);
null meshes are not displaced by default.

Optional facetThis setting determines which side of the surfaces (facets) that make up a mesh are omitted (culled) from the rendering result.
When rendering meshes, all surfaces that make up the mesh face a certain direction. This direction is often called the normal direction. This normal is used to determine if the surface is being seen from the front or the back. When rendering objects that have no holes in them, it is only possible to see the front of all surfaces. Graphics pipelines therefore often don't render the back sides of those surfaces to speed up rendering.
Apart from performance, some applications are made possible by enabling back-face culling. Consider for example a mesh that represents a room. Its normals would all point to the inside of the room. When enabling back-face culling, you can see the walls and floor of the room, without having to move the camera inside the room itself.
In some cases however, enabling back-face culling (i.e. not rendering the back-side of surfaces) can have undesired artifacts. This can for example happen:
Both can be resolved by disabling culling.
By default, no culling takes place and both sides of a surface are painted.
// Example of enabling backface culling
meshStyle.facetCulling = FacetCullingType.BACKFACE_CULLING;

Optional lightingBoolean indicating whether lighting effects should be applied to the mesh.
The graphics effects. This boolean indicates whether the lighting graphical effects should be applied to meshes styled with this style.<code>true</code>
Optional mipThis setting determines which mip map filtering to use when rendering large textures on small areas.
Mipmap filtering is a technique used in computer graphics to improve the quality of textures when they are displayed at different sizes. When a texture is displayed at a smaller size, the system selects the most appropriate smaller version (mipmap) to reduce visual artifacts.
If the mipmap filtering is set to MipmapFilteringType.BASED_ON_DATA and the data does not specify any type of filtering, then no mipmap filtering will be applied. In this specific case, mipmap filtering is only enabled if the data explicit says it is needed.
However, mipmap filtering is not compatible with every type of texture. In effect, tile sets that use a texture atlas may introduce visual artifacts. If you notice such artifacts, you should turn to MipmapFilteringType.BASED_ON_DATA or MipmapFilteringType.NO_MIPMAP_FILTERING.
This parameter should only be set during initialization. Modifying the filtering subsequently may result in the new parameter not being applied to previously loaded geometries. A warning will be issued if the filtering is changed post-initialization.
By default, MipmapFilteringType.BASED_ON_DATA is assumed.
// force linear mipmapping
meshStyle.mipMapFiltering = MipmapFilteringType.LINEAR_MIPMAPPING;

Optional selectedAn expression to specify what colors to apply to selected mesh data.
To create expressions, you must use the factory methods in the ExpressionFactory module. The expression must be well-formed and resolve to a color value. This value can also be set to null to prevent selection from changing the color. If you want to update the styling very often, consider using parameters in your expression. Changing the values of parameters is more efficient than replacing the whole expression. If you define a selectedColorExpression, the texture data, if any, will not be displayed while selection is active for the selected part of the mesh. The color expression will determine the color.import {color, defaultColor, multiply} from "@luciad/ria/util/expression/ExpressionFactory.js";

import {TileSet3DLayer} from "@luciad/ria/view/tileset/TileSet3DLayer.js";

An orange color expression.
Optional visibilityAn expression to filter mesh data.
To create expressions, you must use the factory methods in the ExpressionFactory module. The expression must be well-formed and resolve to a boolean value.If you want to update the styling very often, consider using parameters in your expressions. Changing the values of parameters is more efficient than replacing the whole expression.
// Example of a visibility expression that makes everything inside a shape invisible.
var _ = ExpressionFactory;
var shape = _.orientedBox(layer.orientedBox);
meshStyle.visibilityExpression = _.not(_.isInside(shape));
null meshes are visible by default.
