Re: [visad] Strange rendering depending on axis range

Hello Sir...

Actually there will be no effect of setting texture ON or OFF when using ShadowImageByRef renderer.
You can try that.
I dont know when it will become part of the source code. For time being keep a copy of the two classes.

Its really nice to hear that our work is useful to you.

regards
Ghansham

Hello Ghansham,

I can confirm that using your updated classes, the rendering of the mass 
spectrometry data set (with texture = OFF) looks good, and there are no 
artifacts when rendering high resolution data. Good job, thank you very much!

Are you planning to include this change in the official VisAD source code, or 
should I keep my own modified version for the time being?

Best regards,

Tomas

Hello Sir

Attached herewith a modified version of ShadowImageByRefFunctionTypeJ3D and a 
slightly modified version of ShadowFunctionSetTypeJ3D.
Keep the old jars.

Kindly recompile them and just see this time you will be able to see the 
details you have been looking for.
Just confirm me if there any artifact that is coming higher resolution. I have 
tested in both the programs that you sent me. I am seeing no issues.
Just let me know if there are any.

I will again quote the same DISCLAIMER NOTICE:
It is pretty much a TEMPORARY (not very TESTED) solution but still very 
EFFICIENT ;-)

This is something pretty New as Tom Rink Sir says "DISCOVERY BY ACCIDENT" :-)
because we are able to generate this type of surface details using geometry 
only.

But now we are doing it using Textures.

It is gonna change our way we were thinking till now in visAD.


with regards
Ghansham

R/Sir

I would suggest you to just check with the modified render for the range
setting issue.
That will be really appreciated.

Hi Tom,


formally setting the ranges to decimal values fixes the problem for me.

Just a followup to this issue: setting the range to 44027 -  44028 shows the 
same problem, despite using decimal values (screenshot is attached).

Dear Gransham,

Please note that this issue only appears with texture set to OFF.
When I set textures to ON, I get a nice flat plane (using default renderer) .
When I use your modified DisplayRendererJ3D, I also get a nice flat plane.

Best regards,

Tomas
