Loading 3D Models + Textures (Read 3752 times)

Markavian Full Member Offline Posts: 174	Loading 3D Models + Textures May 16^th, 2005, 4:28am Anyone know any leads for loading 3D model files and using associated textures using processing? I was hoping to make a simple viewer for some 3D models I've been making (~600 polys), nothing fancy.

Using the MAX2OBJ export plugin for 3DSMax I was able to create an obj and mtl that works (to some degree) with SAITO's library. MAX2OBJ: http://www.habware.at/duck6.htm I couldn't get it work with an internet explorer applet though.

you could use some of my script, http://wliia.org/projects/3dcam/, i rewrote the obj-loader to http://www.xs4all.nl/~elout/ this guy, and made it into a class.. not very nice looking though.
And i made a camera-class, but the code is quite tricky, since there's no way of locking the cursor when you're online.. so if you move your mouse slowly around, it works ok, but if you drag it hard, it spins abit..

but i hope you can extract some usefull information from it, and beware, i'm not sure i'm keeping the sketch up for that long, so get it while you can..

Take a look at: http://mkv25.net/applets/camera_and_3d_mouse/ Right click to rotate. Middle button to zoom. Arrow keys move 'block' around. Press 'c' to centre on block. Press 'r' to centre on grid.

funny, i was just on that site, without knowing it was yours, and i copied your script for referance later on

but my cameraclass is with mouselook (like half life), and that was really not what i was referring to in that script.. it was actually the obj-loader, because that one works online.. you might have to rewrite alot of it though, but it displays obj files with textures, online..

Sorry I just thought I'd mention the camera thing.

I had a go with the code that you provided, I find it much messier and harder to get on with then SAITO's code. I get alot more lost polygons with that code too, but thats probably due to the way I exported.

I also had trouble getting the texture to display properly, the code seems really sensitive to calls to fill() and noFill().

Its just a shame SAITO's doesn't work online :-\
