Considering thip 4x4 map:
float control_points[4][4][3] = {
{{-30.f, .0f, -30.f}, {-10.f, .0f, -30.f}, {10.f, .0f, -30.f}, {30.f, .0f, -30.f}},
{{-30.f, .0f, -10.f}, {-10.f, .0f, -10.f}, {10.f, .0f, -10.f}, {30.f, .0f, -10.f}},
{{-30.f, .0f, 10.f}, {-10.f, .0f, 10.f}, {10.f, .0f, 10.f}, {30.f, .0f, 10.f}},
{{-30.f, .0f, 30.f}, {-10.f, .0f, 30.f}, {10.f, .0f, 30.f}, {30.f, .0f, 30.f}}
};
It gives me garbage when rendered. Shouldn’t it give me a flat grid ?
I searched NV_evaluators in google, but didn’t manage to get a single tutorial or code snipet. The only example I found is the uncommented Bumpy Shiny Patch demo from cass…
