Hi,

I'm trying to load a 3d file (.ifc), and I'm trying to find my way with the tutorial 6 (which must be outdated I guess). After some change on tutorial's code, I still got some errors that I don't know how to fix.

Maybe someone can help :)

My issue is on the callback of the "auto complete = ..."

auto complete = sceneManager->assets()->loader()->complete()->connect([&](file::AssetLibrary::Ptr assets){
        auto root = scene::Node::create("root")->addComponent(sceneManager);

        auto camera = scene::Node::create("camera")
        ->addComponent(Renderer::create(0x7f7f7fff))
        ->addComponent(Transform::create(Matrix4x4::create()->lookAt(Vector3::create(0.f, 0.f, 0.f), Vector3::create(0.f, 0.f, 5.f))))
        ->addComponent(PerspectiveCamera::create((float) WINDOW_WIDTH / (float) WINDOW_HEIGHT, (float) PI * 0.25f, .1f, 1000.f));

        root->addChild(camera);

        auto objModel = assets->symbol(OBJ_MODEL_FILENAME);
        auto daeModel = assets->symbol(DAE_MODEL_FILENAME);
        auto ifcModel = assets->symbol(IFC_MODEL_FILENAME);

        // change scale for the obj file
        objModel->component<Transform>()->matrix()->appendScale(0.01f);

        // change position
        objModel->component<Transform>()->matrix()->translation(-1.f, -1.f, 0.f);
        daeModel->component<Transform>()->matrix()->translation(1.f, -1.f, 0.f);

        // add to the scene
        root->addChild(objModel);
        root->addChild(daeModel);
        root->addChild(ifcModel);

        auto enterFrame = canvas->enterFrame()->connect([&](Canvas::Ptr canvas, float t, float dt)
        {
            sceneManager->nextFrame(t, dt);
        });

        canvas->run();
    });

Do you have any error message? Did you try without loading only your IFC? (don't queue the DAE and OBJ files)

unco182 commented 8 years ago

For now, I'm just trying to build this tutorial with no error. But it seems that some class are not existing anymore

auto complete = sceneManager->assets()->loader()->complete()->connect([&](file::AssetLibrary::Ptr assets){

Do you know how to make this compile, I got an No viable conversion from '(lambda at /Users/albanpellegrini/Developer/openIFC/src/main.cpp:61:75)' to 'Callback' (aka 'function<void (std::__1::shared_ptr)>')

Thx in advance

Noxalus commented 8 years ago

The signature of the complete signal is not the same anymore, you get a pointer of the Loader instead of a pointer of the AssetLibrary.

auto complete = sceneManager->assets()->loader()->complete()->connect([&](file::Loader::Ptr loader)
{
    // Your code
})

All tutorials are really old and outdated, I suggest you to look at the examples instead. (cube example is a good start)

unco182 commented 8 years ago

Thx for this!

Do you know if I can find somewhere a list of the main change that happened on Minko ? (such as change of type name...)

Noxalus commented 8 years ago

Someone is currently working on the update of tutorials (code + documentation), and it should come soon.

For the main change, we had something like that for the migration of Minko beta 2 to Minko beta 3. I hope it can help.

Minko to GLM math expressions equivalent

Transform common usage

Beta 2	Beta3
`transform->x()`	`math::vec3(transform->modelToWorldMatrix() * math::vec4(math::vec3(), 1)).x`
`transform->y()`	`math::vec3(transform->modelToWorldMatrix() * math::vec4(math::vec3(), 1)).y`
`transform->z()`	`math::vec3(transform->modelToWorldMatrix() * math::vec4(math::vec3(), 1)).z`
`transform->matrix()->prependTranslation(x, y, z)`	`transform->matrix(transform->matrix() * math::translate(math::vec3(x, y, z)))`
`transform->matrix()->appendTranslation(x, y, z)`	`transform->matrix(math::translate(math::vec3(x, y, z)) * transform->matrix())`
`transform->matrix()->prependRotationX(angle)`	`transform->matrix(transform->matrix() * math::rotate(angle, math::vec3(1.f, 0.f, 0.f)))`
`transform->matrix()->appendRotationX(angle)`	`transform->matrix(math::rotate(angle, math::vec3(1.f, 0.f, 0.f)) * transform->matrix())`
`transform->matrix()->prependRotationY(angle)`	`transform->matrix(transform->matrix() * math::rotate(angle, math::vec3(0.f, 1.f, 0.f)))`
`transform->matrix()->appendRotationY(angle)`	`transform->matrix(math::rotate(angle, math::vec3(0.f, 1.f, 0.f)) * transform->matrix())`
`transform->matrix()->prependRotationZ(angle)`	`transform->matrix(transform->matrix() * math::rotate(angle, math::vec3(0.f, 0.f, 1.f)))`
`transform->matrix()->appendRotationZ(angle)`	`transform->matrix(math::rotate(angle, math::vec3(0.f, 0.f, 1.f)) * transform->matrix())`
`transform->matrix()->prependScale(x, y, z)`	`transform->matrix(transform->matrix() * math::scale(math::vec3(x, y, z)))`
`transform->matrix()->appendScale(x, y, z)`	`transform->matrix(math::scale(math::vec3(x, y, z)) * transform->matrix())`
`transform->deltaModelToWorld(v)`	`math::normalize(math::mat3(transform->modelToWorldMatrix()) * v).xyz`
`transform->matrix()->lookAt(lookAt, position, up)`	`transform->matrix(math::inverse(math::lookAt(position, lookAt, up)))`
`transform->deltaWorldToModel(v)`	`math::normalize(math::mat3(math::inverse(transform->modelToWorldMatrix())) * v).xyz`

Matrices

Beta 2	Beta3
`Matrix4x4::create()`	`math::mat4()`
`matrix->determinant()`	`math::determinant(matrix)`
`matrix->rotationQuaternion()`	`math::quat(matrix)`
`matrix->translation()`	`matrix[3]`
`matrix->invert()`	`math::inverse(matrix)`

Vectors

Beta 2	Beta3
`Vector3::create()`	`math::vec3()`
`vector3->x()`	`vector3.x`
`vector3->y()`	`vector3.y`
`vector3->z()`	`vector3.z`
`vector3->length()`	`math::length(vector3)`
`Vector3::zero()`	`math::vec3(0)`

Data

Container class is now called Store instead.

Please use three blackquotes (```) to surround a block of code instead a single one (that is used for inline code).

This code is still wrong on many points. Here is what you should have instead:

    auto canvas = Canvas::create("Minko Tutorial - Loading 3D files", WINDOW_WIDTH, WINDOW_HEIGHT);
    auto sceneManager = component::SceneManager::create(canvas);

    sceneManager->assets()->loader()->options()

Also I saw this info: Logger.hpp:45 write(): Debug, T0: IFC: skipping IfcAnnotation entity due to importer settings and I would like to be able to get these annotation if I succeed in displaying my file. Where should I look to change this importer settings ?

Thanks in advance

warrenseine commented 8 years ago

You should look at the Assimp plugin IFC parser (here).

unco182 commented 8 years ago

Thanks warrenseine,

While loading my file I got this error happening in Renderer.cpp:

Any idea why this error happen ? I'm going to try with an other ifc but I'm not sure it gonna change anything

EDIT : With an other .ifc I have the same behavior (see the log in my previous post)

Noxalus commented 8 years ago

Yes, it seems that some surfaces of your IFC files don't have effect associated. You can set a default effect on each surfaces in the loader options.

sceneManager->assets()->loader()->options()->effect(sceneManager->assets()->effect("effect/Basic.effect"));

Obviously, to do that, you need to load the Basic effect before to load your IFC file.

unco182 commented 8 years ago

Thanks, but I think its not working (Or I'm doing sthg wrong again !).

I put sceneManager->assets()->loader()->options()->effect(sceneManager->assets()->effect("effect/Basic.effect")); at the beginning of my code and I got the same error

Full code :

#include "minko/Minko.hpp"
#include "minko/MinkoSDL.hpp"
#include "minko/MinkoASSIMP.hpp"

using namespace minko;
using namespace minko::component;

const math::uint WINDOW_HEIGHT = 600;

const std::string IFC_MODEL_FILENAME = "pirate.ifc";
//const std::string IFC_MODEL_FILENAME = "4333_EGI_ARC_0000_ECP_GSY_A-Niveau_1.ifc";

int main(int argc, char** argv)
{
    auto canvas = Canvas::create("Minko Tutorial - Loading 3D files", WINDOW_WIDTH, WINDOW_HEIGHT);
    auto sceneManager = component::SceneManager::create(canvas);

    sceneManager->assets()->loader()->options()->effect(sceneManager->assets()->effect("effect/Basic.effect"));

    sceneManager->assets()->loader()->options()
    ->registerParser<file::IFCParser>("ifc") // We need to register the IFC parser to load ".ifc" files
    ;

    sceneManager->assets()->loader()
    ->queue("effect/Basic.effect")
    ->queue("effect/Phong.effect")
    ->queue(IFC_MODEL_FILENAME)
    ;

    auto root = scene::Node::create("root")
    ->addComponent(sceneManager);

    auto camera = scene::Node::create("camera")
    ->addComponent(Renderer::create(0x7f7f7fff))

    ->addComponent(PerspectiveCamera::create((float) WINDOW_WIDTH / (float) WINDOW_HEIGHT, (float) M_PI * 0.25f, .1f, 1000.f));

    root->addChild(camera);

    auto complete = sceneManager->assets()->loader()->complete()->connect([&](file::Loader::Ptr loader)
    {
        // Retrieve our IFC model
        auto symbol = sceneManager->assets()->symbol(IFC_MODEL_FILENAME);

        // Add the symbol to the scene
        root->addChild(symbol);
    });

    auto enterFrame = canvas->enterFrame()->connect([&](Canvas::Ptr c, float t, float dt)
    {
        sceneManager->nextFrame(t, dt);
    });

    sceneManager->assets()->loader()->load();
    canvas->run();

    return 0;
}

warrenseine commented 8 years ago

You should put that line in your complete handler. The effect is not yet loaded when you try to use it.

unco182 commented 8 years ago

Thx, but It's still not working wherever I put the line of code in the complete handler

Noxalus commented 8 years ago

You need to load the Basic effect with another loader to do what you want. Thus, you can load your file only when the other loader has loaded the Basic effect. This should looks like that:

#include "minko/Minko.hpp"
#include "minko/MinkoSDL.hpp"
#include "minko/MinkoASSIMP.hpp"

using namespace minko;
using namespace minko::component;

const math::uint WINDOW_WIDTH = 800;
const math::uint WINDOW_HEIGHT = 600;

const std::string IFC_MODEL_FILENAME = "model/myfile.ifc";

int
main(int argc, char** argv)
{
    auto canvas = Canvas::create("Minko Tutorial - Loading 3D files", WINDOW_WIDTH, WINDOW_HEIGHT);
    auto sceneManager = component::SceneManager::create(canvas);

    // Create a loader to load effect files
    auto effectLoader = file::Loader::create(sceneManager->assets()->loader());
    effectLoader->options(effectLoader->options()->clone());

    // Add effect files to load
    effectLoader
        ->queue("effect/Basic.effect")
        ->queue("effect/Phong.effect");

    // Set options for the default loader (the one use to load our file)
    sceneManager->assets()->loader()->options()
        ->registerParser<file::IFCParser>("ifc");

    sceneManager->assets()->loader()
        ->queue(IFC_MODEL_FILENAME);

    auto root = scene::Node::create("root")
        ->addComponent(sceneManager);

    auto camera = scene::Node::create("camera")
        ->addComponent(Renderer::create(0x7f7f7fff))
        ->addComponent(Transform::create(math::inverse(math::lookAt(math::vec3(0.f, 0.f, 5.f), math::vec3(), math::vec3(0.f, 1.f, 0.f)))))
        ->addComponent(PerspectiveCamera::create((float) WINDOW_WIDTH / (float) WINDOW_HEIGHT, (float) M_PI * 0.25f, .1f, 1000.f));

    root->addChild(camera);

    auto effectLoaderComplete = effectLoader->complete()->connect([&](file::Loader::Ptr loader)
    {
        // Retrieve the Basic effect from loaded assets library
        auto basicEffect = sceneManager->assets()->effect("effect/Basic.effect");
        // Set the default effect to apply on each surface
        sceneManager->assets()->loader()->options()->effect(basicEffect);

        // Start the file loading
        sceneManager->assets()->loader()->load();
    });

    auto fileLoaderComplete = sceneManager->assets()->loader()->complete()->connect([&](file::Loader::Ptr loader)
    {
        // Retrieve our IFC model
        auto symbol = sceneManager->assets()->symbol(IFC_MODEL_FILENAME);

        // Add the symbol to the scene
        root->addChild(symbol);
    });

    auto enterFrame = canvas->enterFrame()->connect([&](Canvas::Ptr c, float t, float dt)
    {
        sceneManager->nextFrame(t, dt);
    });

    // Start the effects loading
    effectLoader->load();

    canvas->run();

    return 0;
}

Yaaay ! It kinda works ! Thanks !

I now can load my file, but it display nothing but a grey screen (see screenshot).

Your model might be too small/large, try to scale it:

symbol->component<Transform>()->matrix(symbol->component<Transform>()->matrix() * math::scale(math::vec3(0.01f)));

What I'm doing wrong?

Please use the latest version of minko on master or dev branches if you're building new projects.

Ok I use master, but now have another issue.

Just use load 3d files tutorial.

File does not exist But all files in asset folder. I checked.

Noxalus commented 8 years ago

This is due to the fact that some assets copy instructions are missing to the premake5.lua file. Try adding this at the end of the file:

minko.package.assets {
    ['**'] = { 'copy' }
}

I just edited shell script like on screenshot below and it works now. Thanks a lot. screen shot 2016-03-08 at 7 24 10 pm

Need to fix it. Otherwise for beginners like me it's taking a lot of time to get started. I spent whole day just to fix this issue.
