meshc — Render a wireframe surface with contour lines projected onto the base plane.

meshc(X, Y, Z) draws a wireframe mesh and overlays contour lines on the XY plane.

GPU behavior

Single-precision gpuArrays stream directly into the shared WebGPU renderer.

Double precision falls back to host gathers until SHADER_F64 is available.
