Hi PaQ, yeah as various pieces speed up probably memory consumption will be a bigger barrier for you. MoI as a 32-bit program can get up to around 4GB (well in the neighborhood - maybe more like 3.6GB) on a 64-bit OS though, not just 3GB... Also I think that probably implementing an instancing mechanism may actually help out more than 64-bit-ness for a lot of cases.

I certainly understand that you'd like a 64-bit version of MoI, but in order to do it would require a major churn in my development environment needing to switch to a new compiler and updating all support libraries and dealing with various compatibility issues from that. That's going to be very disruptive for me and so I don't think it's going to be likely to happen anytime too soon.

Was this an initial concious decision, or is it just a bi-product of starting the dev cycle before the proliferation of 64 bit?

Hi Burr,

Pretty much the byproduct part...

But it also doesn't help that each new version of Visual Studio has kind of gotten worse in various ways and that's another thing that's kept me from going to new versions for a while.

Thanks Michael, I understand.

Hey Danny, how about Phineas J. Whoopee's 3D BB (Black Board)!

Hi Michael T.

Not that familiar with Tennessee Tuxedo might of been a little before my time, plus I don't think we got all the US toons here down under.
Amazing that Don Adams did Tuxedo's voice though! I still catch an episode or two of 'Get Smart' :)

Cheers

Ok, new v3 beta is out, you can get it here: http://moi3d.com/beta.htm?rev=x

It may take me a day or two to gather up more info and make the official announcement.

But briefly the new stuff is:


Multiple cpu cores used in the draw engine - should speed up the display of complex models on multi-core machines. Please let me know how it benchmarks on your system, you can get a numeric benchmark by turning on the viewport display time which will put up a number in the upper-left corner of the viewport for how long it took to render a frame. You can toggle that on and off by setting up a shortcut key with the following script on it:
script: /* Toggle redraw time display */ moi.ui.showViewportDisplayTime = !moi.ui.showViewportDisplayTime;

You can compare numbers with that turned on in the previous v3 beta or v2 to the new multi-core enabled release.


PDF import has been totally overhauled, it should be a lot more robust and some kinds of PDFs that would previously get garbled should come through ok now.

New Extrude to point and Extrude tapered options for the Extrude command (2 new buttons on the Extrude options panel).

New Isocurve command under Construct > Curve > Iso, and a new "Isoparm" option for the Trim command when trimming a single surface.


I'll try to gather up some more details and make a proper announcement within the next couple of days.

Cool
We can go to the camping with the new release!
Bravo!

Thanks Michael G.! Hope to check it out sometime today!

Michael T.

Nice new icons transform !
But maybe the generic Deform must be different than the Flow ?

Cool the new extrude functions :)


Perfect the iso curves!

Hi Michael!

...some benchmarks:

Inventor import via IGES with ~250 objects, older INTEL Quad. Selected all objects, reset view and did some "serious" rotating..

mesh angle 10:

MOI 2: ~193-207ms
MoI 3.0 beta Apr: ~200-216ms
MOI 3.0 beta Jul: ~99-103ms

mesh angle 5:

MOI 2: ~460 ms
MOI 3.0 beta Jul: ~216ms

BOOOM!
I did check the CPU Usage History. All 4 Cores online..



Great work,
~ Marco

WOW PDF import has been totally overhauled INDEED that's a game changer, no more Round-trip :)

2.5


3.0

Here is my test opening a 100Mb filesize
Windows task manager show performance when loading the file

MOI V3 20 JULY=1023 ms

MOI V3 16 APRIL=1150 ms



Intel core quad 9450-8 Gb RAM

Thanks Michael ...

Thanks Michael,
Awesome.

Hi Michael,

Thanks for the beta :

Here's a first bench,



I'm using fraps and the autorotate script, bench time : 30 sec

MOI V3 April : Frames: 293 - Time: 30000ms - Avg: 9.767 - Min: 8 - Max: 13

MOI V3 July : Frames: 583 - Time: 30000ms - Avg: 19.433 - Min: 15 - Max: 22



Me happy :) ... will try to do some other test if I find some models here on my office computer.

Great stuff Michael!

Tapered Extrude works great! That feature alone will have a lot of fans especially the product design and Mech Eng guy's,
all we need now is a separate 'Draft' feature and that toolset will be complete ;)

I'll try out the new features soon, meanwhile here are the benchmarks I'm getting with my machine;

Machine Specs
My humble CPU: Core2 Duo E6750@2.66GHz
Graphics: Nvidia Quadro FX3500

Model
36063 Edges
13611 Faces

Benchmark Results
V2....210ms-235ms
V3....160ms-180ms
30% speed increase

V2(Display Hidden Lines).....330-350ms
V3(Display Hidden Lines).....230-250ms
40% speed increase

Cheers
~Danny~

MOI V3 April : Frames: 256 - Time: 30000ms - Avg: 8.533 - Min: 7 - Max: 9

MOI V3 July : Frames: 803 - Time: 30000ms - Avg: 26.767 - Min: 17 - Max: 31

Really nice result on this one !

MOI V3 April : Frames: 175 - Time: 30000ms - Avg: 5.833 - Min: 5 - Max: 7

MOI V3 July : Frames: 357 - Time: 30000ms - Avg: 11.900 - Min: 10 - Max: 13

Hi Michael,

Great job on the new tools!!!! =-D

I like the IsoParm features on both Project and Trim commands.
The Extrude to a point is good too because you can make instant pyramids.
The Taper (draft) function is going to be useful, but I found I was able to make ugly of it when the shape to extrude was too complex.
It's nice to have icons on the Flow features now.


Okay... I'm slightly miffed about the CPU improvement.
I guess you were right when you said that results would be dependent on what you were running.

I set up the older MoI and the new release with my "Boiler Watch" model. It has 1073 ojects. at 75 megs (file).
I tried it on my home PC earlier this morning and I really didn't notice any difference in speed (when heavily rotating the 3D view).
I have some kind of old NVidia with P4 Intel CPU... But I didn't expect much on that machine.

I thought I'd get better results at work, but I guess it could already be souped up somehow...

Here is my test with the "Boiler Watch":

My Work PC has these specs:
Processor: Intel(R) Core(TM) i7-2600K CPU @ 3.40GHz
RAM: 16.0 GB System: 64-bit
Vid card: NVIDIA GeForce GTX 560
CUDA Cores: 336
Graphic clock: 850 MHz
Processor clock: 1701 MHz
Mem clock: 2052 MHz 4104 MHz data rate

Nothing is overclocked as far as I know.

This is the Fraps log:

2012-07-20 11:11:07 - MoI (for older version)
Frames: 21 - Time: 5569ms - Avg: 3.771 - Min: 4 - Max: 7
Moi's counter is aprox: 160ms

2012-07-20 11:13:29 - MoI (for newer version)
Frames: 18 - Time: 4680ms - Avg: 3.846 - Min: 4 - Max: 7
Moi's counter is aprox: 160ms

This is a real negligible difference.

With the old version I could see at least one processor going, with another two at a lower rate.
With the new one all were cranking pretty well.

Note that my CPU is really a 4-core with hyper-threading to make eight.

So, am I'm I doing something wrong, or was there something originally with my system that could be gaining an advantage?
I do, however, notice a little less lag time when zooming in and out with the mouse's scroll wheel.






So, why am I not seeing any noticeable increase when the processor use chart begs to differ?
Could it be that Moi is now just eating more CPU for kicks? ;-)
