I think I got the compositing nodes to a usable state. It consists of an object library full of nodes and an update to my rsx plugin. Also included is a bump map to normal map converter that runs faster than the script only version I posted last year. They can be downloaded here:

http://www.clintons3d.com/plugins/trues ... index.html"

you can see a list and brief description of the nodes here:

http://www.clintons3d.com/plugins/trues ... eNode.html"

I'll try to get some kind of tutorial/instructional materials out in the near future.

Hello clintonman,

I'm very interested in these compositing tools.
Question: do these take as input a sequence of images or an avi, or do they take input from the current output of a 3D window (or windows)? The latter would be outstanding!

Also, do you have a sample scene file we could look at to help learning?

Thanks a lot for this - I'm sure it was a lot of work.

It only reads image sequences. So no avi or any other movie format. They cannot read from the 3d view like perspective, right, top... but you can read images from a scene camera by using the D3D Texture render target node. You can find a sample scene in the Render to Texture library. The node has a Preview refresh input that can be turned on by changing the value from 0 to 1. It's texture output can be sent to the compositing nodes.

I'll see what I can do about the learning materials. It's in the plan but I haven't gotten around to it yet.

Hi Clinton,

The input from camera sounds interesting.
Thanks for the info.

Update:
Fixed some bugs and made small aspects for the nodes so they fit better in the link editor.

Hi Clinton,
I've been trying out the composite nodes and am having a problem.
When I hook up an image loader to a composite render node then to a camera
the image in the window looks a bit blurry compared to the original.
I made sure that the nodes and the window had the same resolution (WxH) as the image.
(646X474)
Any suggestions?
Thanks.

I just recently found out that the textures inside the composite render node had compression turned on. I added an updated composite render with compression turned off to the downloads about 2 days ago. Do you have the latest?

Oops, I just looked back through the posts and I see I forgot to mention it. The Composite Render and Composite Render with Alpha nodes were updated on May 16. The only update is that the Enable Compression check on the texture nodes was unchecked. Compression for textures is on by default but it can cause blurriness and other artifacts in a material.

Got it, Thanks.

clintonman · Post by **clintonman** » 30 May 2016, 00:48

Wow, a long time between updates.
I needed a fast blur for a project I'm working on and so I updated a few other nodes as well.

New nodes - basic perlin noise and interlace. Interlace alternates between to images every other line or so. The noise was part of an experiment that I never really finished years ago and only just discovered it sitting in the code base. The interlace was used when I needed to combine 2 image sequences, one from the truespace camera and another from a video. It was used to line up my tS animation with a real flight path for the lunar lander.

These nodes are faster by a factor of 5:
blur, convolve, channel combiner/splitter, image zoom, color difference matte and the bump2normal map
I only needed the blur and bump2normal and don't have plans to do any others. The biggest bottleneck now is the image loader node. If I can ever fix that (without much work) then it will be worth it to speed up the rest of the nodes.

Update for 2018:

Added procedural texture nodes based on Blender 3D code: perlin, cloud, marble, voronoi and wood. Uses the latest rsx plugin. These are the same nodes used in the Yafaray update.
updated color picker that works with the web based color picker( was a separate download before)

That's quite nifty. It's cool to see the realyime viewport get some nodal love.
I have to admit I used your nodes mostly in materials.

clintonman · Post by **clintonman** » 01 May 2019, 00:51

April 2019 Update:

All nodes updated to higher speed versions.
New Image Resample node for changing the size of a bitmap
Includes a missing Image Crop node
Updated Color Curves script - was changed before but never documented in any way.

Uses updated rsx plugin file.

http://clintons3d.com/plugins/truespace ... iting.html

If loading into an Unofficially updated truespace, only the Color Curves, Crop and Resample needed to be copied from the zip archive, along with the new rsx plugin file.

clintonman · Post by **clintonman** » 05 Apr 2020, 22:16

April 2020 Update

Improved Bump2Normal node for conversion of grayscale images to tangential normal maps.
Has better math for the conversion and adds a strength control

The new node and updated rsx file can be downloaded from this page:

Is it possible to save a sequence of files to disk with your Image Saver?
BTW... getting undefined errors with this object.
I notice that your are saving a sequence of bitmaps into an Encapsulate node with your 'image sequence loader with scale'.

Was trying to see if I could Import and then Export a sequence of bitmaps at 0.5 Scale.

I'll have to get back to you on that. I had no recollection of the 'image sequence loader with scale'.
Went to check it on the webpage: http://clintons3d.com/plugins/truespace ... eNode.html
and it had in bold, "An experimental/unfinished node called "image sequence loader with scale" is included in the library/zip. Do not use it."

Workaround for saving a sequence from the same page:
"Use the Truespace "Render to File" to render a dummy sequence which in turn will force each frame to be evaluated."
This would save a sequence of images from the image saver

Hummm... I'll have to disagree, it works really well!

Very useful for sharing a sequence of images in a scene and reducing the file size.

I changed it from Create to Copy so that I could experiment with changing the InputBitmap's attributes.

Code: Select all

//newimage = Node.Create("D3D View Package/InputBitmap", encaps);
newimage = Node.Copy(System.ThisOwner() + "/InputBitmap", encaps);

Still testing your workaround, but so far, since it is a jScript, it does not work with Animation. IE: Render to File

Just seems that if you can save the Bitmaps to an Encaps, you would think you could also save to disk using your Save As plugin.

I believe jscript objects work with render to file and jscript commands don't.

Both of these Image Savers creates a Model Status message "file dialog aborted" if you Cancel the Save As and it is not cleared.

I would like to update the image saver.RsObj in the Unofficial Updates with your newer version.
Is it possible to add the TIF options? That is of course if it supported with your Clintons3dPluginExt.rsx plugin.
Edit: Did a test and the image saver did not save an image using tif and or tga

clintonman · Post by **clintonman** » 13 May 2020, 17:50

Did some digging and on the surface it looks like the bitmap file save command only works with some extensions:
From the Kernel.h file

Code: Select all

enum RtBitmapFileFormat
    {	BFILEFMT_BMP	= 0,
	BFILEFMT_JPG	= 1,
	BFILEFMT_TGA	= 2,
	BFILEFMT_PNG	= 3,
	BFILEFMT_DDS	= 4,
	BFILEFMT_DIB	= 6,
	BFILEFMT_HDR	= 7,
	BFILEFMT_PFM	= 8,
	BFILEFMT_FORCE_DWORD	= 2147483647
    } ;

I'm surprised TGA doesn't work but maybe a slightly different command is needed. It uses SaveToFile, maybe it needs to use SaveToFileEx.
From the Docs:

Code: Select all

HRESULT IRdBitmap::SaveToFile ( [in] RtBitmapFileFormat  Format,	[in] BSTR  FileName	 ) 			

This method is used to save image to a file.

Code: Select all

HRESULT IRdBitmap::SaveToFileEx ( [in] RtBitmapFileFormat  Format,[in] BSTR  FileName	 ) 			

This method is used to save image to a file using external image library (alpha channel supported).

Nope, that's not it. Just did a test and TGA save was good without any changes to the saver.

Looks like formats not included in the list above would need a different way to save the images.

trueBlue · Post by **trueBlue** » 13 May 2020, 21:44

I was testing this the wrong way.
I was expecting it to save an image by just using the Save As button.
I see now that it is an jScript Object and that you need to run the Render to File.

I have updated the image saver.RsObj to your newest one and will upload to the Unofficial Updates.
The older one has a Save As tif option that does not work.

When you do the "Save As" button it should save something immediately if the "enableSave" checkbox is active.

Not even sure how it was working

Problem is, the SwitchImage script is connecting an IN attribute to another IN attribute

//	Node.ConnectTo(newimage, "Bitmap", switchnode, "Bitmap")
	Node.ConnectTo(newimage, "oBitmap", switchnode, "Bitmap")

new rsx plugin v1638431
http://clintons3d.com/plugins/truespace ... index.html

The image cloud color option only half colored bug is fixed
Also the "no undo" script commands have been altered to work more like the built in tS Node commands in that they don't error out with invalid node definitions.
The tS Node.Copy, Rename and Value all give errors with nonexistent nodes, so the "no undo" versions have not been altered.
Delete, Disconnect, DisconnectAll, ConnectTo, ConRemove along with ClearStatusMessage will no longer give errors because of invalid nodes. This should make it easier to work with them.

Image Multiply is brightness and contrast.

Maybe the render target has some default post process that's making it brighter?

Your Image Multiply seems to help

Yep. "Alpha Value Only check will multiply the rgb by the alpha in input. Unchecked and each rgba will be multiplied individually."

I'll do a test when I get a chance. I never notice the brightness issue before. Just had a thought, maybe the node is tuned for default tS lights and UU lights give a different result.

trueBlue · Post by **trueBlue** » 12 Dec 2021, 04:38

UU lights should be the same as tS lights besides the panel icon scripts and meshes

It looks like the Root has to have a valid value. If you encapsulate and set the Root properly it still works.

I didn't know you could use the EyeCamera_xxx like that. I thought it had to be a camera in the scene.
