 | | Problem with color scaling option in LPub
|
|
Hello, I’m having a little rendering problem and I’m not quite sure what is causing it. I’m using LPub to do my BI’s, so, naturally, I use the color scaling option. However, the main construction images in mpd files render without the color scaling (...) (21 years ago, 1-Feb-04, to lugnet.cad.ray)

(...) [Lightbulb pops on] Aaaahhhh!! :) Now it all makes sense. So when the original model was created, it must not have been at <0,0,0> in MLCAD. With that in mind I checked out the coords and you all are absolutely right. I picked out one of the (...) (21 years ago, 29-Jan-04, to lugnet.cad.ray)

Hi I think that this is caused by the fact that the original MLCAD model is not centered in the virtual space. If you move it so that it's center is at 0,0,0, the camera will rotate around it. /Not 100% sure but I did replicate the above using a (...) (21 years ago, 29-Jan-04, to lugnet.cad.ray, FTX)

(...) If you just do a straight "L3P model.dat," then you're right; the whole model fits very nicely in the camera's view (though a little fish-eyed, I find). But if you switch the view to orthographic, the model can appear a bit off-center and (...) (21 years ago, 23-Jan-04, to lugnet.cad.ray)
