[osg-users] float == 1.0f?

Hi Robert. I just got stuck on something I been worried about for quite some time regarding the Math library in osg: bool Matrix::isIdentity() const { return _mat[0][0]==1.0f _mat[0][1]==0.0f _mat[0][2]==0.0f _mat[0][3]== 0.0f _mat[1][0]==0.0f

Re: [osg-users] float == 1.0f?

Hi Anders, The equality test is an exact equality test, same with isIdentity(). One could relax it by adding an epilson to it, but this would not be an exact equality, so would be better placed in a separate method. Robert. On 2/26/07, Anders Backman [EMAIL PROTECTED] wrote: Hi Robert. I

Re: [osg-users] float == 1.0f?

Sure, I agree, the EPSILON was there for an example, so where the rest of the macros. I dont want to introduce a macro with a hard limit into a library, Im just pointing out that when is an exact float test really appropriate? An example: osg::Matrix m1, m2; m1.makeRotate(osg::PI_2,

Hi Elekis, It looks like you might be missing Producer now. If you don't need osgProducer/Producer then you can build the OSG without it just fine. You just need to disable the building of osgProducer/osgproducerviewer by setting the env PRODUCER_INSTALL=no or editing the Make/dependencies
