PolylineMaterialAppearance

An appearance for PolylineGeometry that supports shading with materials.

const primitive = new Primitive({
geometryInstances : new GeometryInstance({
geometry : new PolylineGeometry({
positions : Cartesian3.fromDegreesArray([
0.0, 0.0,
5.0, 0.0
]),
width : 10.0,
vertexFormat : PolylineMaterialAppearance.VERTEX_FORMAT
})
}),
appearance : new PolylineMaterialAppearance({
material : Material.fromType('Color')
})
});

Properties

When true, the geometry is expected to be closed so PolylineMaterialAppearance.renderState has backface culling enabled. This is always false for PolylineMaterialAppearance.

The GLSL source code for the fragment shader.

The material used to determine the fragment color. Unlike other PolylineMaterialAppearance properties, this is not read-only, so an appearance's material can change on the fly.

The WebGL fixed-function state to use when rendering the geometry.

When true, the geometry is expected to appear translucent so PolylineMaterialAppearance.renderState has alpha blending enabled.

The VertexFormat that this appearance instance is compatible with. A geometry can have more vertex attributes and still be compatible - at a potential performance cost - but it can't have less.

The GLSL source code for the vertex shader.

Functions

Link copied to clipboard

Procedurally creates the full GLSL fragment shader source. For PolylineMaterialAppearance, this is derived from PolylineMaterialAppearance.fragmentShaderSource and PolylineMaterialAppearance.material.

Link copied to clipboard

Creates a render state. This is not the final render state instance; instead, it can contain a subset of render state properties identical to the render state created in the context.

Determines if the geometry is translucent based on PolylineMaterialAppearance.translucent and Material.isTranslucent.
