Imogen

GPU/CPU Texture Generator

GPU Texture generator using dear imgui for UI. Not production ready and a bit messy but really fun to code. This is an hybrid project that can run natively or on the web (thanks to emscripten). Basically, add GPU and CPU nodes in a graph to manipulate and generate images. A web build is available here : http://skaven.fr/imogen/ Currently nodes can be written in GLSL or C or Python.

Use CMake and VisualStudio to build it. Windows and web builds are available.

Web Edition limitations:

no threaded jobs
no C/Python nodes
no Python plugins
no file load/save

Features:

Node based texture editing
material library browser
edit/change node shaders inside the app
bake textures to .png, .jpg, .tga, .bmp, .hdr, mp4
PBR preview
timeline for parameters animation

Currently implemented nodes

circle and square generator
sine generator
checker transform
transform
Mul/Add
smoothstep
pixelize
blur
normal map from height map
sphere/plan previewer
Hexagon
Mul-Add colors
Blend (add, mul, min, max)
Invert color
Circle Splatter
Ramp
Tile
Polar coordinates
...

imogen's Issues

.EXR input/output

Suggestion: Vector Nodes

node list
*vector integer2
*vector integer3
*vector integer4
*vector float2
*vector float3
*vector float4
*crossProduct
*dotProduct
*length
*normalize
*distance

Imogen web version

Compiled 0.13 (because 0.14 is not ready yet) with emscripten.
http://skaven.fr/imogen/imogen.html
Many, many, like, many broken stuff BUT it runs. Pretty happy with the result.
Branch is https://github.com/CedricGuillemet/Imogen/tree/dev-0.13-emscripten
run emb.bat to compile it once you have emscripten sdk installed and activated.

C Node question

I've been playing around with the node editor and it is a ton of fun. I have a question about the C nodes. I've been trying to add more functionality to the C nodes and I am attempting to include libraries like stdio and the like, but if I add an include to any of the C node scripts I get a rotating set of errors that either say source not found, relating to the ntdll.dll or an "InProcessClient.pdb not loaded, Access violation writing location" error. Any ideas?

Thanks!

Error in C node code will result in app crash

Investigate these kind of crash. To reproduce it, add a syntax error in any node .c code

Redirect stdout & stderr to Console

This would be particularly useful with the Python interpreter

Creating looped graph leads to broken data

If you have two items with input and output, and connect them back to each other, not only does the application crash, but it saves the state of the project so that if you load the same graph again, it immediately crashes.

Crazy idea here

Would it be possible to integrate this with shadertoy? It would be ridiculously awesome

Building on linux

I have been trying to build it on Linux, but I'm having some compilation errors, the first one was regarding BGFX_CONFIG_RENDERER_OPENGLES, I manage to fix it by changing

https://github.com/CedricGuillemet/Imogen//blob/dev-0.14/CMakeLists.txt#L82
to be
ADD_DEFINITIONS(-DBGFX_CONFIG_RENDERER_OPENGLES=31)
but now I'm getting:
undefined reference to 'stbi_write_png'
when linking.

By the way, great work, with a little bit of marketing it can become a huge open source project.

Node lister

Few things about node lister.

Did not found a way to remove it without creating a node, escape key should hide it again?

Also to create it, using a key as well as button is generally nice (space key is common in many softwares).

FFmpeg Seek frame functionnality

The seek call in the FFMPeg decoder always brings back to frame 0. I tried multiple things and it's still buggy with frame TS.

https://github.com/CedricGuillemet/Imogen/blob/master/ext/ffmpegCodec.cpp#L399

Heelp!

Better UI Idea & Web Issue

Idea: Maybe you can make your UI better looking if you use blender 2.8 UI.
Issue: Material previews are blank, if I try one of the examples that happens too.

Imogen v0.4.0 Known issues

cubemap filtering is a prototype
ktx in/out is not tested

Parse .glsl code to generate meta datas

For now, the metadatas are stored in Library. I'd like to get more freedom/reactivity and generate the metadata (basically parameters and types) from a parsing (threaded/jobified) of those .glsl

Suggestion: Logical nodes

node list
*Logical AND (&&)
*Logical OR (||)
*Logical NOT (!)

Release 0.2

Previously planed for this weekend, v0.2 is a bit delayed as I rewrote the evaluation code multiple times this weekend. I'm more happy with it but it can still be better. I will release it monday or tuesday

Web build doesn't build materials / show anything

When I open any material in the web version at http://skaven.fr/imogen/ it lacks any preview, and manually hitting "Build current material" gets stuck at 0%.

I'm using Firefox 72.0.1 (64-bit).

There are some warnings and errors in my browsers debugger console, but I'm not sure which one would be relevant to this. I'm not sure if this issue only affects me or also other users / browsers. I can probably provide more details from those logs if requested. For now I'll assume that this issue is easy to reproduce (I believe #76 also mentions this problem?).

[web edition]Download generated images

Change the filewrite node for the web that will do an automatic download of the generated image instead of writing it to disk.

Suggestion: Conditional node

node list
*equal (==)
*not equal (!=)
*greater than (>)
*greater than or equal (>=)
*less than (<)
*less than or equal (<=)

Suggestion: Constant Nodes

To define static values for your graph

node list
*float
*float2
*float3
*float4
*integer
*integer2
*integer3
*integer4
*boolean

Instead of separate nodes, One single node called constant with drop down list to select data types would be great.

0.6.0 crashes immediately on start

windows 7 64bit

0.5.0 works

using gdb i found:

Node header when graph is unzoomed goes outside node boundaries

Hello, here is a small cosmetic issue as per the screenshot here :

Thanks

Is Imogen dead?

There hasn't been any development in quite some time.
Is this project still active or expected to become active again?

I've been checking for new releases, but nothing seems to have happened for more than a full year now - no commits and no releases.

I'd really love to see Imogen develop, as there isn't really any solid FOSS PBR seamless map generation tool out there, and Imogen seemed to be a very promising project.

Sadly I wasn't ever able to use it due to problems with running it on Linux.

Selecting node bounding area is incorrect

Hello, another small issue, starting to select inside the node (when zoomed in) starts the selection tool instead.

Thanks

AO computation node

From a heightmap as input compute a resulting AO.

Creating node when zoomed and pan positions it in the wrong place

Hello, as per the gif here

When creating the node I would hope to have it in the place I initially set right click.

Thanks

Creating connection between nodes, small improvement

Hello, as per the screenshot here :

Dragging the connection from the transform to the transform should pick the first available connection, this makes authoring much much faster.

iqnoise is pixelated

Arch Linux, Nvidia, driver 430.34, Imogen dev-0.14.

Linux/Macos port

Everything is coded with multiplatform in mind (mostly). And I compiled the project on a virtualized Ubuntu. It was a couple months ago and a Linux port (a solid one) would be great.
Kudos if there is a possibility to produce binaries(packages) from a bot.

Suggestion: function nodes

node list
*absolute - return absolute value
*acos - inverse of cos
*asin - inverse of sin
*atan - inverse of tan
*angle - angle between two nodes
*ceil - return the smallest integer value that is not less than the argument
*floor - return the largest integer value that is not greater than the argument
*trunc - return the largest whole value that is not greater than the argument
*clamp - clamps to the min-max range, If number is outside the range, the return value is clamped to min or max, otherwise.
*sqrt - square root

SVG input

use this lib : https://github.com/memononen/nanosvg
don't forget to update the readme

[Web Edition]Support links

In web version, update function void OpenShellURL(const std::string& url) to open link in a new browser tab.

Fix Tile Node

Link from project Does this only need an initial value of 1 or something else?

@CedricGuillemet

Replacement for libtcc

Currently some nodes (paint, file read/write) are coded in C using libtcc. There are some unrecoverable errors, will not work in JS world because of JIT and I don't feel like recompiling libtcc with emscripten. I'm looking for alternative solution. 1 might be to replace it with a JS interpreter. What are other options?
