This function gets the number of triangles in a surface.

Syntax

• int CountTriangles()

Returns

Returns the number of triangles in a surface, which is equal to the number of indices divided by three.

Example

#include "Leadwerks.h"

using namespace Leadwerks;

int main(int argc, const char *argv[])
{
        Leadwerks::Window* window = Leadwerks::Window::Create();
        Context* context = Context::Create(window);

        Camera* camera = Camera::Create();
        camera->SetRotation(35, 0, 0);
        camera->Move(0, 0, -3);
        Light* light = DirectionalLight::Create();
        light->SetRotation(35, 35, 0);

        Model* model = Model::Box();
        model->SetColor(0.0, 0.0, 1.0);
        Surface* surface = model->GetSurface(0);

        //Print out the triangle indices
        for (int t = 0; t < surface->CountTriangles(); t++)
        {
                System::Print(String(surface->GetTriangleVertex(t, 0)) + ", " + String(surface->GetTriangleVertex(t, 1)) + ", " + String(surface->GetTriangleVertex(t, 2)));
        }

        while (true)
        {
                if (window->Closed() || window->KeyDown(Key::Escape)) return false;

                Leadwerks::Time::Update();
                world->Update();
