What is PI?

I never used to make this mistake. When I started my last project I thought something had changed but I went to 0.95 and it was the same. 

As ENSONIQ5 says it depends whether you are thinking I'm watching or I am the object  As soon as I switched my head to being the the object it all makes sense. 

I don't think it should be changed, but I do like to understand. :)

General Anim8or Forum / Re: Stereo (3D render)

I've been selecting the stereo view and doing a render. I've got the xvid codec installed.  I can create a file that is compatible with my TV, side by side stereo, reasonably sized file in 1080p or 1/2 1080p.  The stereo setup provided by Anim8or (I think) the problem is that it makes the objects appear too close with my setup - hence difficult to focus. I have been experimenting with dimensions / distances but because the render takes so long and the TV is not often available for testing, it takes ages to get any results.

I tried something similar a couple of years ago and did this "manually".  Carmer01R is parent of Camera02L, offset by about 4" (my scaling in affect, 1 Animator unit is 100mm or 4"). Cameras are parallel.  I get better stereo effect results but poor resolution because the only way I know to build the 3D file from the 2 renders is stereo movie maker (the Japanese one) that has limited output formats.  I use 640x480 (1280x720 does not produce a "valid" file for me) and I cannot find how to force it to use the xvid codec.  If I post process the output through xvid miniconvert I get an incompatible file for TV.

Iíve been using a fixed object and moving the camera.  Itís just occurred to me to use a fixed camera and several rotating objects at different distances.  Then look for which object gives the best visual result Ė next test planned.

Trial, error and patience required....

General Anim8or Forum / Stereo (3D render)

Has anyone got any tips for getting the best results from a stereo 3D render?

I just tried a quick test with a sphere, box and a cube and moved the camera around and then over the objects.  The result on my TV is very hard to focus on and something goes horribly wrong when the camera goes over the objects.

I cannot see any settings for the stereo render, can the distance between left and right be set anywhere?

That makes sense,  I was thinking from my point of view.  I knew I'd feel daft when someone answered this :)

Sorry if this is a daft question, its really basic stuff. :-[
V0.98 (any version Iíve tried), object editor. When I select left view I see a view from the right and visa versa.  Front looks from the front, back from back, etc.  Is there a setting that flips left and right or have I just got it in my head that this is flipped?

See attached env from my laptop.

I do not have any compatibilty mode set.

On the laptop I can hang in a similar way - using MorphTarget.an8, scene mode, view camera, options loop scene, play, click the checkered ground grid between the left tool bar and the camera view port (green box) twice. Same in new and old rendering modes although I clicked 4 times using the old mode before it hung.

I had only noticed this in camera view.  Raxx - the screen shot you have in front view is the same as I see in camera view and I can recreate hang in front view by clicking the ground grid as above.

Hope this is useful

My video card on this box (Dell Optiplex 790) is a Dell branded ATI radeon HD3450.

It has ATI driver which is an old driver (just spent 30 mins trying to find the updated).  This is probably why the acceleration looks unusual.  I've got 3 of these systems, the first one  runs XP and I know that it has the driver supplied on disk with the systems (this box probably got the driver from MS update).

I didn't mention before that this is not a single system problem.  My laptop does the same, I post the specs later.  I'll test the XP box as well.

Edit  [Attached environment definition with updated ATI adapter driver.  The problem is similar but not the same. If I put loop scene on and play (spinning cube) after a couple of loops Anim8or stops responding, however the rendering of the spinning cube appears behind the "greyed out" Anim8or app. (Presumably running on the graphics card now.)
OpenGL verion top right of screen is now OpenGL 3.3]


Is there a working issue list so I can check that I am not reporting a known problem?

Versions in Anim8orEnv.jpg (Win7 32, OpenGL1.1)
Open GL 1.1 shown top RHS.

I thought this was repeatable but as I write it up I find its 50-50.

Iíve had this problem with a number of recent versions.  This is tested on 1071.
Open the attached MorphTargets.an8.  Go to scene mode. Switch to view camera. Set loop scene under options loop scene.  Click play in the left tool bar. Watch the frame indicator in the lower panel and click stop when it is at about 1s (not sure if the location is relevant).  If a wait cursor is shown, Anim8or is hung.  It does not always hang, if not repeat play / stop.  I get typically 50% anim8or will hang.
Sometimes if I leave the scene playing it will hang without clicking stop.  I first noticed with Spinning cube and thought it was related to rendering the texture, not sure.
Open the attached SpinningCube.an8 (needs Penguins.jpg for a material).  Go to scene mode, view camera. (The image fills my screen). Click play. The cube rotates to about frame 36(ish) of 96 and the scene freezes. After about 10s the frame marker appears at the end of the scene and the last frame is shown.  Repeat with loop scene: Anim8or hangs.  Today this is not very repeatable - typical.  While playing click stop or click in the frame indicator (lower panel on line +scene01 :00Ö) and it will behave as I describe.  With loop scene on it hangs indefinitely.

Ctrl-N to use original OpenGL interface.  Similar problem caused by clicking in the frame indicator at about frame 36 while playing. Stop button appears more reliable (gut feel = luck) but will still hang in the same way.
Hope this is useful

I'm no morph target expert but I can manage a bendy stick.  See attached file. The object has 3 morph targets that are animated in the scene.

There is a good tutorial on morph targets here:

Hope this is what you are after.

That would be perfect. :)
Thanks for all the effort you put into Anim8or.

Hi Raxx

Tried the scripts.  Local gives me 'strange' results.  If I draw a cylinder under my mesh with the same width as the mesh (front view width is x) and run the script it shows different results for the x dimension of the mesh and the cylinder.  I think that I have rotated the mesh at some point and the local script gets the dimension from the original orientation. 
So I switched to the absolute script.
This got me closer to a result but my object that I am trying to measure consists of three meshes so I'd have to add the results together.  I moved
                            $maxx = 0;
      $maxy = 0;
      $maxz = 0;
      $minx = 0;
      $miny = 0;
      $minz = 0;
out of the loop so that the bounding box would contain all the selected meshes.  The output now shows the size of the bounding box increasing as the shapes are consumed:

 "mesh01" -> 49.826 x 95.323 x 81.620
 "mesh02" -> 99.652 x 95.323 x 81.620               Is located to the right of mesh01
 "cylinder01" -> 113.936 x 95.323 x 100.991        Protrudes to the right of mesh02
 "cylinder02" -> 122.219 x 95.323 x 119.994        Protrudes to the right of cylinder01

(Print result statement $ should be $shapes[$i].name in both scripts as all shapes were reporting the same name.)

Thanks for your help with this, I would never have got that far without your scripts as a starting point.

Thanks Raxx I'll try with your scripts.

Has anyone ever requested a measure distance facility in at least object mode?  I quite often want to sketch things to scale.  When I want to measure the length of a mesh I draw a cylinder from A to B and then open its properties to see the length.  Or is there already a quick trick for measuring objects?

« on: August 22, 2013, 09:56:06 am »
Hi Raxx, I made the object entirely in Anim8or.  Yesterday I an edge going nowhere and deleted it.  Is there an "easy way" to find unconnected edges or do you do it by inspection?
I only added the tesselation to make fill holes work.  Fill holes and I don't get along; a hole with several points at the top of my 45 degree cyclinder will not fill or it fills and and the face appears to break over into the bore of the cylinder.  I can fix this by adding egdes to each hole so it only has three edges.
Duplicate points I try to fix using merge points, it there an easy way to know when you have 2 points overlapped?
(I really struggle to "see" the correct points that need to be linked together- takes me hours.  I put it down to lack of skill :)   )

How can you tell when a face has concave polygons?

Hi Ron,   You've spotted what I'm doing - I'm using the arc rotate tool instead of rotating as Ensoniq5 suggested.

Thanks all. BTW I've printed the part and its come out OK.
