how to draw a nice mesh

[Dave M]

hello every one, i have problem with  drawVertices ,i have a segy section data as below

gridding mesh make trips,each point with a color then i use  drawVertices code：

SkPaint filPaint;

filPaint.setAntiAlias(true);

filPaint.setStyle(SkPaint::kFill_Style);

float spaced = 200.0;

SkPoint testPts[6] = { SkPoint::Make(0, 0), SkPoint::Make(spaced, 0),

SkPoint::Make(0, spaced), SkPoint::Make(spaced, spaced),

SkPoint::Make(0, spaced * 2), SkPoint::Make(spaced, spaced * 2) };

SkColor colors[6] = { SK_ColorGREEN, SK_ColorRED, SK_ColorYELLOW, SK_ColorBLUE, SK_ColorGREEN, SK_ColorRED };

canvas->drawVertices(SkCanvas::kTriangleStrip_VertexMode, 6, &testPts[0], nullptr, &colors[0], nullptr, nullptr, 0, filPaint);

 which i supposed to be 

then i use VTK to render same data  firstly it do same thing like skia,but with vtkMapper::SetInterpolateScalarsBeforeMapping set flag true, i get it.

i want know how can i do it with skia ?
