Ultra Engine testing

[Josh]

It's not supported yet.

[Josh]

Final steps:

• The SSR shader needs to detect and calculate indirect lighting based on whether the material that wrote each pixel uses PBR, Spec/Gloss, or classic shading. These each use a different calculation of specular reflection.
• Clean shader code up a bit.
• Make sure the spec/gloss appearance is correct. A lot of Sketchfab models use this glTF extension.
• ASyncRender will be renamed to AsyncRender

Nice

I would like to add some small thing to the list:

if you clean up the shader code, then you might consider to reanable the mappingscale feature (currently SetMappingScale has no effect, pbr and terrain)

Also if possible: readd the animation texture feature with volume textures, this would make life a lot easier.

and minor feature request: add some more methods to access some major properties:

• Camera:
  • GetMatrix() (projection, view, etc.)
  • GetFrustumn
• Terrain: 
  • a way to get the heightmap texture (not only the pixmap) --> support for gpu based heightmap generation
  • a way to get  / set the alpha mask for each material --> better support for serialization

In the latest version, the UI is not rendered correclty:

There are 100 items in the list and below are 2 tabbers. If you look closely the tabbers are visible, but only the text in a dark grayish color.

#include "UltraEngine.h"
#include "ComponentSystem.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 world
    auto world = CreateWorld();

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

    //Create a camera
    auto camera = CreateCamera(world);
    camera->SetClearColor(0.125);
    camera->SetFov(70);
    camera->SetPosition(0, 0, -3);
    camera->SetViewport(200, 0, framebuffer->size.x -200, framebuffer->size.y);

    auto uiCamera = CreateCamera(world, PROJECTION_ORTHOGRAPHIC);
    uiCamera->SetRenderLayers(RENDERLAYER_1);
    uiCamera->SetClearMode(CLEAR_DEPTH);
    uiCamera->SetPosition(framebuffer->size.x / 2, framebuffer->size.y / 2);
    auto ui = CreateInterface(world, LoadFont("Fonts/arial.ttf"), iVec2(200, framebuffer->size.y));
    ui->SetRenderLayers(RENDERLAYER_1);

    auto sz = ui->root->ClientSize();
    auto listbox = CreateListBox(5, 5, sz.x - 10, 200, ui->root, LISTBOX_DEFAULT)->As<ListBox>();
    auto tabber = CreateTabber(5, 205, sz.x - 10, sz.y - 205, ui->root)->As<Tabber>();
    tabber->AddItem("Settings", true);
    tabber->AddItem("Output");

    for (int i = 0; i < 100; i++)
    {
        listbox->AddItem("Item " + String(i));
    }

    //Create a light
    auto light = CreateBoxLight(world);
    light->SetRotation(35, 45, 0);
    light->SetRange(-10, 10);

    //Create a box
    auto box = CreateBox(world);
    box->SetColor(0,0,1);

    //Entity component system
    auto actor = CreateActor(box);
    auto component = actor->AddComponent<Mover>();
    component->rotation.y = 45;

    //Main loop
    while (window->Closed() == false and window->KeyDown(KEY_ESCAPE) == false)
    {
        if (PeekEvent())
        {
            auto ev = WaitEvent();
            ui->ProcessEvent(ev);
        }

        world->Update();
        world->Render(framebuffer);
    }
    return 0;
}

Hey Josh you might want to check your EULA.

Paragraph 7 looks like it has a typo.

Yeah I know, I'm board.

[Josh]

Update

• Renamed ASyncRender to AsyncRender
• Fixed default terrain Lod distance, added Terrain::SetLodDistance()

Did this same code work correctly in previous builds?

[klepto2]

yes, it worked correctly.

This is not the complete solution, but you can call uicamera->SetDepthPrepass(false) and it will probably look right. This is something you should do anyways, as there is no reason to do a depth prepass when lighting is not in use.

[Josh]

Also, the reason your example is kind of laggy is because it only evaluates one event per loop.  Change your code to this to fix it:

        /*if*/ while (PeekEvent())
        {
            auto ev = WaitEvent();
            ui->ProcessEvent(ev);
        }

 

[klepto2]

Ok. That Was a stupid mistake. Thank you. 

[Josh]

Update is up that should fix your problem, with depth prepass enabled or disabled.

[Josh]

I think what we will do is enable purchases in a few days, so people who are hanging out on the forum can get the new engine, and then wait a couple of weeks for the email blast and big announcements to go out. Most normal people are probably very busy during Christmas.

That's a good idea. Also the forum people will probably be more understanding of any problems they might encounter.

Hopefully the transition will go smoothly. I would like to put money down for the year with my early adoption discount. 🙂

Under the weather right now so hopefully I'll feel better by then.

Creating a panel seems to disable transparency on the ui roots widget...

#include "UltraEngine.h"
#include "ComponentSystem.h"


using namespace UltraEngine;


int main(int argc, const char* argv[])
{
    auto displays = GetDisplays();
    auto window = CreateWindow("Ultra Engine", 0, 0, 1280, 720, displays[0], WINDOW_CENTER | WINDOW_TITLEBAR);
    auto world = CreateWorld();
    world->RecordStats();

    auto framebuffer = CreateFramebuffer(window);

    auto camera = CreateCamera(world);
    camera->SetClearColor(0.125);
    camera->SetFov(70);
    camera->SetPosition(0, 2, -3);

    auto font = LoadFont("Fonts/arial.ttf");
    auto ui = CreateInterface(world, font, framebuffer->size);
    ui->SetRenderLayers(RENDERLAYER_1);
    ui->root->SetColor(0, 0, 0, 0);


    auto ui_cam = CreateCamera(world, PROJECTION_ORTHOGRAPHIC);
    ui_cam->SetPosition(framebuffer->size.x / 2, framebuffer->size.y / 2, 0);
    ui_cam->SetRenderLayers(RENDERLAYER_1);
    ui_cam->SetClearMode(CLEAR_DEPTH);

    auto panel = CreatePanel(10, 10, 100, 100, ui->root);

    auto light = CreateDirectionalLight(world);
    light->SetRotation(35, 45, 0);
    light->SetRange(-10, 10);

    auto floor = CreateBox(world, 1000.0f, 0.1f, 1000.0f);

    while (window->Closed() == false and window->KeyDown(KEY_ESCAPE) == false)
    {

        world->Update(120);
        world->Render(framebuffer);
    }
    return 0;
}

While we wait for the new editor, how one can make maps/levels for Ultra?

Perhaps using the LE Editor and then import the .map by code using C++? Right?

[klepto2]

UltraEngine has a Legacy-Importer which can load the Leadwerks files (map, mat. tex, etc.) while not everything is supported right now you already can load maps created with the Leadwerks Editor. but keep in mind, that the Legacy materials and models will use a different shader family, so you might not get PBR out of the box in Leadwerks maps.

[Josh]

Update

• Fixed GUI transparency problem reported above.

[Josh]

Update

Make sure you update your project with the updated shader files.

DDS loader will now skip mipmaps smaller then 4x4 when a compressed format is used.

SSR is working with specular / gloss shader family now. The equation is a little different, so that has to be account for in the final SSR pass:

This is a good model for testing the specular/gloss extension: https://sketchfab.com/3d-models/valley-of-kohoutovice-1-08eb64a5f54a4f8c9d2eb2f313c3b651

I will do some more testing now, but I think 1.00 is finished.

[Josh]

I renamed the default channel to 1.0.0. I recommend you uninstall and reinstall it (not the client, just the engine).

I'll check out this RC build tonight. I think it's important to double check Leadwerks compatibility is perfect.

[SpiderPig]

Did a clean reinstall like you said.  I mucking around with UI and have noticed if I simply re-run the program below seconds apart I get a different draw order (or transparency?) each time.  Project is up to date with new shaders.

#include "UltraEngine.h"
#include "ComponentSystem.h"


using namespace UltraEngine;


int main(int argc, const char* argv[])
{
    auto displays = GetDisplays();
    auto window = CreateWindow("Ultra Engine", 0, 0, 1280, 720, displays[0], WINDOW_CENTER | WINDOW_TITLEBAR);
    auto world = CreateWorld();
    world->RecordStats();

    auto framebuffer = CreateFramebuffer(window);

    auto camera = CreateCamera(world);
    camera->SetClearColor(0.125);
    camera->SetFov(70);
    camera->SetPosition(0, 2, -3);

    auto font = LoadFont("Fonts/arial.ttf");
    auto ui = CreateInterface(world, font, framebuffer->size);
    ui->SetRenderLayers(RENDERLAYER_1);
    ui->root->SetColor(0, 0, 0, 0);



    auto ui_cam = CreateCamera(world, PROJECTION_ORTHOGRAPHIC);
    ui_cam->SetPosition(framebuffer->size.x / 2, framebuffer->size.y / 2, 0);
    ui_cam->SetRenderLayers(RENDERLAYER_1);
    ui_cam->SetClearMode(CLEAR_DEPTH);

    auto panel = CreatePanel(10, 10, 100, 100, ui->root);

    auto p2 = CreatePanel(5, 5, 75, 75, panel);
    p2->SetColor(1, 0, 0);

    auto p3 = CreatePanel(5, 5, 50, 50, p2);
    p3->SetColor(0, 1, 0);

    auto light = CreateDirectionalLight(world);
    light->SetRotation(35, 45, 0);
    light->SetRange(-10, 10);

    auto floor = CreateBox(world, 1000.0f, 0.1f, 1000.0f);

    while (window->Closed() == false and window->KeyDown(KEY_ESCAPE) == false)
    {

        world->Update(120);
        world->Render(framebuffer);
    }
    return 0;
}

 

[Josh]

@SpiderPigThanks for the example, that was an easy fix. Update is available now.

The reason this was kind of tricky to get right is because Ultra does not draw 2D graphics in the order they are supposed to appear. It uses the depth buffer to determine which object should be in front of another, just like the rasterizer does in regular 3D rendering. That means it does not have to switch materials when drawing a batch, and makes it really fast with complicated interfaces.
