Interface: MeshShaderHooks
Experimental
GLSL spliced into the Plotly-model shader ('plotly' / 'flat' materials) at its hooks, e.g. surface contours or a wireframe overlay. Varyings available to fragment hooks: vLocal (RTC position), vViewPos, vNormal, vValue (intensity relative to its origin, with intensity); color is the straight-alpha sRGB color. Vertex hooks also apply to the pick pass (e.g. a displacement); uResolution / uPixelRatio (CSS px) are available to declare.
