Jirr & E_MATERIAL_TYPE

Post by Serg Nechaeff »

Hi everyone,
I am playing with the JIRR thing at the moment and everything works fine, Jirr is grear, Irr is great but there is no shaders example in the Jirr distribution package. I tried to convert it myself and I am stuck on the following line:

Code: Select all

node.setMaterialType((E_MATERIAL_TYPE)newMaterialType1);
Java doesn't perform such a cast, I tried to do the

Code: Select all

node.setMaterialType(E_MATERIAL_TYPE.swigToEnum(newMaterialType1));
that gave me the exception: No enum class net.sf.jirr.E_MATERIAL_TYPE with value 23

If anyone knows how to solve this or has had luck with shaders code for Jirr, your help would be highly appreciated. Thanks!

I think maybe Jirr just doesn't work for some things, things that Stefan hasn't got round to fixing up quite yet, and this may be one of them. I think i ran into something similar myself a while ago. Have you asked on the Jirr forum?

But there must be a way to change the material type!

Thanks everyone. However I have decompiled the Shaders example code that for some reason is not in the Jirr source package. Here you go:
