Poor Render Quality

Kerry Fullington · Post by **Kerry Fullington** » Sun, Oct 21 2007, 3:02PM

I am working on some moldings for pediments and even though everything is created in eCabinets, the segments show in the rendered views. Imported curved or turned items also render poorly. This wasn't the case in version 4. What has changed?

Kerry,
I am not aware of any changes to our rendering functions. Try turning up the level of detail under \"settings/preferences\". But I am not telling you anything you already know. I will check with our programmers on this one.

Todd,
It seems like eCabinets used to create more segments to make a smoother render when you model something.
I also noticed that when I save geometry for a tool that I have created using a spline, When I open that geometry again the spline is now segmented lines and can't be used .

Kerry,
The programmers say that there may have been some adjustments to the tesselation factors to help with performance. Also, we will look into a means of offering this adjustment to the user in the future.

Thanks Todd,
I can turn the curved moldings into display parts for rendered views. This will accomplish what I want for now. I would like to be able to toggle to get better quality in rendered views.

Kerry,

I'm surprised that you didn't realize that this was probably a problem with the \"tesselation factors\". That was the first thing that came to my mind.

We need to be able to adjust the darn \"tesselation factors\" even if we are clueless about them.

I like the bends you put into this Kerry. Nice work!

By the way tesselation factors control the number of lines in a 3D model. More lines use more memory and computer resourses but produce the smoothest look. I think programmers try to find a balance between performance and the final appearance.

Joe,
I thought it was the tessellation factors all along but I didn't want to say anything.

Paul,
That isn't the correct curve for the piece yet. I was trying out the tool to see how it is going to mate with the straight moldings. I still have a little problem. I have already created eight tools to model this piece and still have at least three more plus some carvings.

I hope the programmers realize that as woodworkers we should never sacrifice quality for performance or profit.

Contrary to the most obscured belief regarding the tessellation factors there is a reality that needs to be addressed here. The scientific community dating back for years now it has been sporadically referring to this as the redundancy of chiliad.

This is an overbearing controversy compared to the never ending debate concerning the vectorization module. In fact it was quoted by a major leader in the scientific community, \"The graphical matrix is getting' a junk value in the display parts translation vector\"

Regardless of the outcome there is hope. Thermwood

Thanks for reading.

Thank you so much Michael for clarifying that.

It's like I always tell people, you don't need to be a rocket scientist to use eCabs. I have no problems and I only have a BS in engineering.

It looks to me like you also hold a BS in something Michael.

Hey Rick...I think Mike confused tessellation with tesla and got zapped

Michael Yeargain · Post by **Michael Yeargain** » Tue, Oct 23 2007, 6:12AM

I hold a BS in my home and sometimes on the net. But that is only acceptable if the people have accepted the credidation from my former school of HK.

It could have been the zap from a telsa but I was clearly out of my mind when I quoted the scientific leader; Scotty from the USS enterprise. There is merit.

Here is a quote from Larry Epplin refferencing this as well.

I did find the problem though. It has to do with the graphical matrix getting a junk value in the display objects translation vector. If an object gets loaded that does not have a pre-existing matrix (such as a cube which is generated on the fly) the problem occurs. This is why ... They have a pre-existing matrix.

You see. I am not crazy!

That doesn't prove you're not crazy...just that you and Larry are playing in the same sandbox

The attached shows how easy it is to hit the tesla switch when one means to hit the tessellation switch.

While in high school, one of my science classes built a Tesla Coil. They did a demonstration on stage at school once but couldn't play with the coil much because at that time (late 60's) most of the houses still received their television signal via antennae and the arc from the coil gave off enough RF signal to destroy reception for blocks around the school. Science is great until it causes someone to miss \"As the World Turns\".
