DebugAppearance
Visualizes a vertex attribute by displaying it as a color for debugging.
Components for well-known unit-length vectors, i.e., normal, tangent, and bitangent, are scaled and biased from -1.0, 1.0 to (-1.0, 1.0).
const primitive = new Primitive({
geometryInstances : // ...
appearance : new DebugAppearance({

Types
Properties
The name of the attribute being visualized.
The GLSL source code for the fragment shader. The full fragment shader source is built procedurally taking into account the DebugAppearance.material. Use DebugAppearance.getFragmentShaderSource to get the full source.
The GLSL datatype of the attribute being visualized.
This property is part of the Appearance interface, but is not used by DebugAppearance since a fully custom fragment shader is used.
The WebGL fixed-function state to use when rendering the geometry.
When true, the geometry is expected to appear translucent.
The GLSL source code for the vertex shader.
Functions
Returns the full GLSL fragment shader source, which for DebugAppearance is just DebugAppearance.fragmentShaderSource.
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 DebugAppearance.translucent.
