objimport library issue in example file (Read 2017 times)

objimport library issue in example file
Oct 25^th, 2009, 3:44pm

I just started playing with the objimport library. When trying to run the simple example I get several errors and the obj file does not get drawn in the sketch window:

java.lang.ClassCastException: java.awt.image.DataBufferInt

Error on line: map_Kd SP_LUK.JPG
Error, could not load obj:/Users/dpcook/Desktop/Processing/libraries/objimport/examples/loadobj/data/s
ponza.obj

Is this a problem between processing and the java installed on my Mac or is it some arcane file reading problem?

Hello Victor,

objimport library is awesome! thanks for your work:)
but, I met a similar error message like the one Daniel met.
Here is the my error message (occurred by example sketch "loadobj"):

My environment are:
- Mac OSX 10.5.8 (Leopard)
- Processing 1.0.9
- objimport library version 1.1.1

when I open the "sponza.obj" file in text editor and disable its' mtl file, and then run the sketch again. The sketch can be run perfectly without texture material.

but i don't know why it does not work with material file >_<

is there any information or hacked way I can do?
any help is very appreciated!!

thank you very much!
