The Contour Line Shader is a powerful shader designed for the High Definition Render Pipeline(HDRP) that visualizes mesh geometry with clean and customizable contour lines. Whether you’re developing stylized environments, scientific visualizations, or data-driven graphics, this shader enables you to display evenly spaced lines along the X, Y, and Z axes of your models with full control.
You can enable contour lines along any combination of axes (X, Y, Z), and customize line thickness(screen-space consistent), line interval and coloring options. Set gradient colors based on Zero (minimum) and Maximum contour line positions, and choose whether to base these positions on Local Space (object-relative) or World Space.
Line thickness is calculated in screen space, not world space, so the visual width of contour lines remains consistent regardless of zoom level or object scale.
Line Options:
Line Interval: Adjustable spacing between contour lines
Line Color: Three contour coloring modes
Line Thickness: calculated in screen space
Emissive Mode On/Off
Choose from three contour coloring modes:
Gradient between Min and Max line colors
Min Color Only
Max Color Only
The shader also supports:
A transparent base color or texture (Base Map)
Specular highlights for a polished appearance
Adjustable Zero and Max line positions
Smooth rendering even beyond defined color bounds by clamping to Min/Max colors
With full axis and color control, Contour Line Shader gives you artistic freedom and technical precision—all in one asset.
