Point Clouds - Vector Point Rendering?

[Josh]

Here you go. Just make sure you have indices as well as vertices:

#include "UltraEngine.h"

using namespace UltraEngine;

int main(int argc, const char* argv[])
{
    //Get the displays
    auto displays = GetDisplays();

    //Create a window
    auto window = CreateWindow("Ultra Engine", 0, 0, 1280, 720, displays[0], WINDOW_CENTER | WINDOW_TITLEBAR);

    //Create a framebuffer
    auto framebuffer = CreateFramebuffer(window);

    //Create a world
    auto world = CreateWorld();
    world->SetAmbientLight(1);

    //Create a camera
    auto camera = CreateCamera(world);
    camera->SetClearColor(0.125);
    camera->SetPosition(0, 0, -1);

    auto model = CreateSphere(world);
    
    //Create point model
    auto model2 = CreateModel(world);
    std::vector<uint32_t> indices(model->lods[0]->meshes[0]->vertices.size());
    for (int n = 0; n < indices.size(); ++n) indices[n] = n;
    auto mesh = CreateMesh(MESH_POINTS, model->lods[0]->meshes[0]->vertices, indices);
    model2->AddMesh(mesh);

    model = nullptr;

    //Main loop
    while (window->Closed() == false and window->KeyDown(KEY_ESCAPE) == false)
    {
        model2->Turn(0, 1, 0);
        world->Update();
        world->Render(framebuffer);
    }
    return 0;
}

Powerfull.
