PyQt5 und PYOPENGL landen von obj datein

[tryyan]

Hallo ich würde gerne mit PyQt5 und Opengl obj dateien dartsellen(laden). Kann mir jemand helfen? Es geibt eben kein Tourtorial.
Hier meine GUI

Du nimmst dir sowas https://pypi.org/project/PyWavefront/ und baust Deine Display Listen aus den Koordinaten. Die haben auch Code für pyglet, den du dir anschauen kannst.

[tryyan]

Ok danke schaue mir das mal an

[tryyan]

Hi irgendwie schaffe ich das nicht kann mir bitte jemand helfen

[__deets__]

Was probierst du denn? Denn "mal bitte helfen" heisst hier, dass sich wer anders ein paar Stunden hinsetzen muss. Das wird eher nicht passieren. Zeig, was du machst, und welche Probleme auftreten.

Oder benutz einfach gleich eine 3D-Engine, die mit Assets dieses (und aller anderen Formate) umgehen kann.

[tryyan]

Hi das ist mir klar und ich möchte auch nicht das jemand mir alles macht. Ich möchte in einer PYQT5 GUI ein 3D model anzeigen. Wieso PYQT5, da ich einen Minecraft Launcher mache in dem man den skin (3D Model anzeigen kann (Drehen und so.)). Ich habe leider kein Modul für das gefunden und bin deshalb auf Hilfe und Ideen angewiesen wie ich diese Problem lösen kann(welche module verwenden). Herzlichen Dank für die Hilfe

[__deets__]

Ich meinte eher, was du konkret probiert hast. Ich habe dir doch ein Modul genannt, mit dem du aus OBJ die 3D-Daten in Python bekommst. Was genau hast du damit angestellt? Denn google bedienen kannst du ja selbst, du hast ja auch schon durch andere Probleme dich erfolgreich durchgearbeitet. Eine "bessere" Integration gibt's also eher nicht, du musst da eben viel Hand anlegen.

[tryyan]

Ah ok das modul das du mir geschickt hast kann auch obj file laden dann schaue ich mir das mal noch genauer an. Danke. Ich habe einfach viel gesuch aber nichts gefunden danke. Schreibe bann so gegen Samstag ein Update

[tryyan]

Ich muss das Projekt aufgeben und als gescheitert betrachten, da ich es Komplet nicht verstehe wie ich obj file darstellen kann in PYQT5. Bin sehr dankbar wenn mir trotzdem jemand weiterhelfen kann. Das Problem inst pywavefront verstehe ich gar nicht und es gibt kein tutorial dazu. Wenn jemand Zeit und Lust hat mir zu helfen, können wir uns auf discord austauschen/ telefonieren.(discord name von mir try#0809 einfach melden).

[tryyan]

Hallo. Ich habe nun einen weg gefunden es umzusetzen habe nur ein kleines Problem, Ich möchte das 3D Modell nur auf etwa ein viertel des Fensters beschränkeng, das ich zum Beispiel noch push Buttons und so hinzufügen kann, kann mir jemand helfen. Es giebt eben immer einen Error. Ich habe ein ähnliches Beispiel gefunden mit push Buttons aber dieses ladet nicht ein obj File und ich kann das nicht einbauen HErzlichen dank
für die hilfe.

@tryyan Das mit dem `m_`-Präfix und den trivialen Gettern macht man in Python nicht. Das `m_` wird in C++ als Konvention benutzt um Member-Variablen leichter erkennen zu können und macht in Python keinen Sinn, weil bei Attributen des Objekts *immer* ein ``self.`` davor steht was diese Aufgabe schon erfüllt.

In Python 3 braucht `super()` keine Argumente.

Dann bleibt von der Klasse nur noch das hier übrig:

Code: Alles auswählen

class RenderableEntity(QEntity):
    def __init__(self, parent=None):
        super().__init__(parent)
        self.mesh = QMesh()
        self.transform = QTransform()
        self.addComponent(self.mesh)
        self.addComponent(self.transform)

Zumindest in dieser Form ist aber irgendwie fraglich ob man diese Klasse überhaupt benötigt.

Die Kommentare im Hauptprogramm die im Grunde nur den folgenden Variablennamen noch mal ”kommentieren” sind überflüssig.

`normalDiffuseSpecularMapMaterial` wird nirgends verwendet‽

Qt-Properties kann man schon beim erzeugen der Objekte angeben, dann spart man sich spätere `set*`-Aufrufe.

Ungetestet:

Code: Alles auswählen

def main():
    ...
    view = Qt3DWindow()

    camera = view.camera()
    camera.setProjectionType(QCameraLens.PerspectiveProjection)

    camera.setUpVector(QVector3D(0.0, 1.0, 0.0))
    camera.setViewCenter(QVector3D(0.0, 3.5, 0.0))
    camera.setPosition(QVector3D(0.0, 3.5, 25.0))

Guten Tag, danke für die Antwort, Sie beantwortet aber meine frage nicht wie kann ich die 3D Simulierung in einem Widget zeigen? Der Code, den du mir geschickt hast und aufgeräumter ist funktioniert nicht es gibt den Error Code Process finished with exit code -1073741819 (0xC0000005) wieder. Herzlcihen dank für die Antwort

[__blackjack__]

@tryyan: Was ist denn das konkrete Problem dabei? Du hast doch da Code gezeigt in dem das Fenster in ein Widged verpackt wird das man dann in einem anderen Fenster anzeigen kann.

[tryyan]

Das Problem ist das es nicht funktioniert. Ich habe das hier probiert und es geht nicht und ich habe keine Ahnung wieso es nicht geht. Herzlichen danke für die Antwort
