Ongoing Anim8or Development / Bone as a Parent to another Element
« on: March 01, 2021, 07:17:50 pm »
The new build v1.01.1396 dated, Feb. 27, 2021 supports making a bone the parent of another element. A character can carry something in his hand, wear a hat, etc., which will follow wherever his hand or head move.

Here's an example of a character throwing a ball. I've attached the project file.

Note: The parent can't be changed, so I have two balls in this project. The first is attached to the character's hand and is hidden at the moment that it is thrown. The second is hidden at the start and becomes visible in the next frame to complete the throw.

Ongoing Anim8or Development / Animated Parameteric Plug-in Scripts
« on: December 24, 2020, 10:44:27 am »
I have a prelimimary version of Anim8or Build 1394+ that supports animated parameteric plug-in meshes. You can reference the frame and time variables to animate them. Here's how it works:

1. Add the new directive #animated after the #plugin("obect", ...) directive.
2. The value of the built in variable "time" will be the scene's time in seconds, and the variable "frame" will be set to the frame number.

There are still a few loose ends in this build, such as the meshes don't revert to frame 0 in the Object editor. I hope to have an oficial buld out soon.

ianross I've modified one of your wave scripts to animate the waves. I added the statement:

$time = $time + time*10.0;

and here's what it looks like in a scene:

If you add a figure to a scene in build 1383 Anim8or will crash. I'll post a fix as soon as I can.

In the mean time, you can use builds 1381 and earlier to build your scene and then switch to 1383 if you want to experiment with the phoneme track.

Ongoing Anim8or Development / Lip Sync Tool
« on: June 08, 2020, 06:52:45 pm »
With Build 1383 Anim8or has a new lip sync track to help add voice. More instructions to come in a few minutes.

Note: I updated the link to 1383 which fixes #101-036 - Anim8or crashes when reading a project that references non existent sounds.

How to use the Lip Sync track to a scene:

1. Start with an Object or Figure that has several Morph Targets that represent different speech phonemes (sounds like "AYE", "OOO", "MMM"). Give them a one letter name or the lip sync track will tend to get jumbled-up.
2. In the Scene editor, add one or more sounds. This creates a sound track.
3. Add the Object or Figure to the scene.
4. Use the Edit->EditPhonemeTrack menu command to add a lip-sync track to the EObject or EFigure. This will appear next to the sound wave in the sound window.
5. Double click on a frame in the lip-sync track to add a phoneme morph.

Existing morphs that conflict with the ones you add in the lip-sync track will be deleted, but you can still use them in other frames. All morphs that are not added to the track are not affected.

This example uses only 4 lip shapes, roughly for sounds A, O, M and N.

You can improve the quality with more shapes. For example, the very talented animator and teacher Preston Blair created a great scheme using 10 different shapes. Here is one description:

I've attached a the project for this video. You can get the .WAV sound file here. When you load the project, switch to the scene editor, double click on the small blank square in sound track at frame 5 and load the sound file.

Ongoing Anim8or Development / Sound in Anim8or
« on: May 01, 2020, 05:20:49 pm »
Beginning with build 1380 Anim8or supports sound. Use the Build->AddSound... menu command to add sound .WAV sounds to the scene. The time track shows a visualization of the sound to help synchronize speech morphs and movement.

Note: While you may use .mp3 and .wav files, only .wav files show the sound wave visualization in the track window!

More to come: Tracks for dialog and sound description, character speech morph targets, and more!

I'm working on some examples to post, so stay tuned!

Note: I updated the above link to point to the latest version on May 6.

ASL Scripts / New Write Image Functions.
« on: March 13, 2019, 05:47:45 pm »
In the latest development build 1356 you can save rendered images in BMP, JPG and PNG format.

class image {
    int WriteBMP(string fName); // All functions return 1 if OK, 0 if failed
    int WriteJPG(string fName [ , int quality = 95 ] ); // 0 = lowest, 100 = highest
    int WritePNG(string fName [, int IncludeAlpha = 0 ] );

image GetImage(int image_id); // Returns NULL if no such image.

I've attached a sample script.

Ongoing Anim8or Development / New Clay-like Display Option in Build 1348
« on: December 13, 2018, 09:09:27 pm »
I just posted a new development release Build 1348 with an option to show models using a clay-like material. This can make it easier to see the shape, especially for complex colors or transparency, without needing to change the material. Just click on the little clay pot in the upper toolbar to toggle it on and off.

Front facing polygons are shown in beige and back facing ones in blue to make it easier to find errors in the direction of normals.

General Anim8or Forum / Arrgh! Hard Disk Crash!
« on: August 10, 2018, 01:53:06 pm »
My disk crashed this week. I have a back-up service for my data. Unfortunately when I added a new disk last April it suspended backing up the Anim8or source files.   :'( :'( :'( :'( :'(

Sooooo, now I get to rewrite everything from mid April. This includes multi threaded rendering and the new bone editing code.

Don't worry, I'll rewrite it all. It was a lot of fun the first time, and it should be even more fun the second!

Ongoing Anim8or Development / New Bone Editing Tool
« on: August 06, 2018, 03:10:42 pm »
As suggested by nemyax in a previous post I'm working on a different way to edit bones (hot key 'J'). I have the first part finished where you click-drag on a joint and it only affects the bones attached directly at that joint. I'm still working on the second part where you can move a group of selected bones.

Please try build 1332 out and let me know what you think, especially the following points:

1. Do you like the new bone joints appearance?

2. Should this new mode be added to the existing Edit Bone tool (hot key 'E') or be a separate tool?

3. Any other feedback is appreciated.

Here's the original video that nemyax posted:

Ongoing Anim8or Development / Multi-Threaded Rendering
« on: July 08, 2018, 03:08:38 pm »
I just posted a new development release  v1.01.1329 dated July 7, 2018 that uses all of your CPU's cores to render ART images. It also has an improved FastAA algorithm that improves shadow edges, especially for soft shadows, and properly ignores shadows from objects marked to not cast shadows.

Note: There are some minor issues, particularly with noise in movies when the image isn't changing. These are cause by the separate threads calling the random number generator in different a different order for each render. I'm working on fixing this.

Please give this build a try. Let me know of any problems that you have, and how much it speeds up your renders.

Ongoing Anim8or Development / File Input add to ASL in Build 1321
« on: March 15, 2018, 07:34:47 pm »
Build build 1321 dated March 15, 2018 supports text file input in ASL Object Command scripts.

The ASL spec has been updated to show the new features. I've attached some sample files as well with a bit of explaination.

file_read_obj.a8s - imports .obj data files.
file_read_tokenize.a8s - lists the contents of a file as tokens.

Here's a link to the part of the spec that describes how to use the text scanner.

Anim8or can prompt the user for the out file name and location with the #file Directive in an Object Command or an Untyped Command script.

The current development release is v1.01.1403, August 29, 2022:

These notes are for the development branch of Anim8or, currently labeled v1.01.xxxx. As changes are verified many but not all will be rolled int the main branch, v1.00x.
