file di interscambio 3D

Per un mio software di ingegneria civile ho la necessità di creare un
modulo che mi consenta di visualizzare il modello solido dei dati
geometrici di elementi solidi residenti in un mio archivio.

In passato ho utilizzato molti tipi di librerie grafiche (es Matrox o
Halo) che però non comprendevano funzioni evolute come le operazioni
booleane; per esse il 3D era solo frutto di routines e algoritmi che
io facevo all'occorrenza.

Ora ci sono le OpenGL e le directX ma non trovo tutorials in italiano
che mi aiutino e mi rendano agevole l'utilizzo.

Ho pensato di utilizzare un modellatore dei tanti esistenti passando
ad essi i dati geometrici tramite file di interscambio. Il più facile
e ricorrente, accettato da tutti i modellatori è il file DXF e l'ho
utilizzato in varie occasioni in quanto è facile da ricostruire via
software; esso però è un file 2D, per il 3D non sono riuscito a
trovare la codifica di lettura e scrittura.
Anche i files POV sono molto facili da realizzare ma il PovRay non è
vettoriale e per me non va bene.
Gli altri files 3D di interscambio in formato ascii sono il SAT
(indecifrabile anch'esso) e, ultimo trovato in rete, il file STEP che
viene realizzato con librerie ISO 10303

Su quest'ultimo sto concentrando la mia attenzione ma non trovo
documentazione sufficiente e possibilmente in italiano.

Chiedo aiuto agli esperti di grafica 3D. Una opinione, un consiglio,
una dritta giusta è bene accetta.

Il mio problema non ritengo sia OT in un NG di C che è il linguaggio
ideale per la grafica 3D

Spero ci sia qualcuno che ha avuto a che fare con questi problemi e in
ogni caso grazie a tutti dell'attenzione .
Saluti,
Tommaso

PS se non sono stato sufficientement e chiaro posso aggiungere
qualsiasi spiegazione

Unfortunately, it is OT. For three reasons:
1) it's an english ng, not an italian one;
2) it's a c++ ng, not a c one;
3) your question is definitely not about c++.

Try to ask in a more related ng.

Zeppe

I have compiled some code, some written by me, some compiled from various sources online, and basically i've got a very simple flat file photo gallery. An upload form, to upload the photos and give them a caption, storing the caption and filename in a text file. It's a bit buggy when removing the photos and captions from the file, and also in displaying them on the delete page. you can see it in action at www.4am.com.au/gallery/upload.php...

Hi There, I have a PHP script that sends an email with attachment and works great when provided the path to the file to send. However this file needs to be on the same server as the script. I want to develop a webpage where people can send attachments that are stored on their local PC.

I am pretty much lost here - I am trying to create a managed c++ wrapper for this dll, so that I can use it from c#/vb.net, however, it does not conform to any standard style of coding I have seen.

Hi, I have a problem that I have been working with for a while. I need to be able from server side (asp.net) to detect that the file i'm streaming down to the client is saved completely/succsessfully on the client's computer before updating some metadata on the server (file downloaded date for instance) However, All examples i have tried, and all examples I have found that other people says works - doesn't work for me :-(

Hello, I created a script to upload a file. To determine the file type I am using userPostedFile.ContentType. For example, for a png image I get "image/png". My questions are: 1. Where can I find a list of all the types which can be returned? For example, if it is a Word document will it return "document/doc".
