I am exploring the possibilities of distributed rendering on azure with batch explorer.
I loved the fact that out of the box you get a lot of tools for 3d rendering, even specifically for blender. However I am having some trouble setting it up for my needs.
On batch explorer the blender gallery template is not up to date. I tried to render something and I was getting black geometry. After some troubleshooting I understood it was because of the principled shader that has only been added in 2.79. If I don't use the principled shader all is good, so I believe the version of blender in the template is outdated.
For this reason I am trying to find a way to create a custom linux build with blender 2.79b, but I got stuck. I am a bit lost with all the guides, tutorials and so on.
It would be great if someone could point me in the right direction for what I actually need to do.
Thank you very much for any help in advance!

I work on a project with curves and sweep on Maya 2022. After testing curves, I'm a little bit dissapointed. Curves are complicated to edit/manipulate. I made some research/tests on different software (houdini, max...) and I would like to try develop a plugin for editing curves in the same way of houdini/max/c4D (a mix keeping best options/editing of these soft). I made some tests (python, openMaya) but my knowledge are limited. I come from AS3/JS so develop in C++ are really intimidating. Help on maya documentation are a bit complicated for me.
So I develop a project (preview) on JS to give you an idea of what I'm trying to do.
I managed to create curves, to apply fillet but I don't understand how I can interact with curves after creating in a panel, how I can add handle to interact with fillet, etc. I find script to add new attributes for each vertex but I would be able to edit coordinates/fillet-chamfer options and I can't edit curve (control vertex) after creation.
Here is a link for my project (develop in JS) : Preview
In the right side, I simulate my panel plugin, on left side the outliner. Instructions are on bottom...
Sorry for my awful english.
Every help, tips are welcome. Please help me.
Thanks
I want to create a 2D sprite that mimic the provided image:
http://a4.mzstatic.com/us/r1000/069/Purple2/v4/e6/0d/73/e60d73a8-6d78-64c2-dd59-9aabb54c7837/mzl.ujapwanw.320x480-75.jpg
and create different face expressions as provided sprites to unity3d in order to create an android application has multiple face expressions with those sprites... so my question... is what exactly the software I might use through out this process ??
Please, let me know the simplest step-by-step procedures, as I am in my first steps in computer graphics.
Thanks a lot.
Image manipulation is what you are looking for. To modify the current image you have and generate other facial expressions from it, you need to be very good at math. Image manipulation is not a basic stuff and I hope you are not new to programming.
Now that you understand that, you need OpenCV to be able to do this. You need to make a wrapper for it in c#. You can get the already made wrapper [here].1 https://www.assetstore.unity3d.com/en/#!/content/21088 .It works on Windows,Mac, Android and iOS and will save you time. Its NOT free but the price is worth it compare to the time you will spend building the wrappers for all platforms.
Once you get this, you can start learning OpenCV from the following link.

If you the Unity plugin I mentioned, you can ask the author of the plugin to help you out if you are tuck.
I apologize if the answer was already somewhere, searching the interwebs did not return me the answer(s) I was looking for.
Situation : I have a small graph (a set of Edges and Nodes that is) - Now I want to display it in an interactive manner, and I would like to manipulate the display styles and symbols that are used for edges and nodes, programetically.
Hence kgraphviewer wont work - i want to do it programetically as stated.
I noticed VTK, comes with a lot of built is graph drawing algorithms. But seems to be a really large one.
Question : What are some alternatives to VTK ? Graphviz is probably one, but I can not confirm that graphviz comes with all the graph drawing algorithms as VTK - any other possibly smaller options, with all the built in graphs?
Side note : Some systems uses a static drawign widget, i.e. once the drawing is displayed, in an widget that the system comes with, you can not interact with the drawing using your mouse. The GNU implementation of IDL, GDL, has this problem. I would Like to avoid this.
Yes, I agree with you regarding the VTK's consideration: it's a powerful toolkit but it is (maybe) too much "big", and it's not so easy to configure a working VTK environment.
I don't have a great experience in the field of graphs, but a search leads to this other StackOverflow post. I think that Prefuse, listed under the Java section, could be of some interest. C++ itself seems to have a lot of choices, listed in various answers, here. I hope that it will help.
I used Gephi public domain graph visualization software on Linux. It was a quick way to get a 3 D. Picture which can be modified with line thickness to show an edge weight - good for comm network work.
I'm looking for an example of multi-threading implementation inside the game toolkit? I have the MultiCube example, but that is for WinForms and I use WPF, and I can't use the game toolkit tools from Direc3D11 because I need an instance of the GraphicsDevice. The MultiCube example is not displaying anything but a black screen, I tried it on several computers. My video card doesn't support command lists, don't know if that has anything to do with it. I was wondering how many models can SharpDX handle, because I have to draw hundreds of small
scaffold couplers, and after adding about a 100 on the default GraphicsDevice, the application slows down and gets locked. Any help would be appreciated.

Haris
I was looking for the same thing but I couldn't find any examples. I tried converting the MultiCube example to use the toolkit and got it basically working, still very messy at the moment and needs optimizing, but at least it renders.

I have been tearing my hair out for a while over this. I need an OpenGL 3.2 Core (no deprecated stuff!) way to efficiently render many sprites, using batching (no instancing).
I've seen examples that do this with geometry alone, but mine also needs to send textures to it, I don't know how to do this.
I need a well done example of it working in action. And looking at how other libs like monogame and such do it isn't much help, because all I'm interested in is the GL code, and it has to have no deprecated stuff in it.
Basically I want to be able to efficiently render thousands+ of sprites, all having textures. The texture is just a spritesheet, so I just need to tell it to render a region of that spritesheet.
I'm disappointed in the amount of material available for programmable pipeline. To the point where it seems like it'd be so much easier to just say screw it and use fixed pipeline, even though I definitely don't want to do that.
So yeah, any full examples that do what I want? Or could somebody more knowledgable write one up? :)
A lot of the examples are "oh, here's how you render 1 triangle". Well that's great, except nobody needs to render only 1 triangle/quad. And they need to be textured in addition to that!
An example that uses VBOs/VAOs/EBOs
ALSO: this means the code can't use glTexPointer and that stuff, but just in raw VBOs/VAOs...
I saw this question and decided to write a little program that does some "sprite" rendering using points and gl_PointSize. I'm not quite sure what you mean by "batching" as opposed to "instancing," but my program uses the glDrawArraysInstanced() call so that I can render multiple points without needing my VBO to be variable sized. My code also doesn't texture the sprites, but that's easy enough to add in (upload the active texture index (the one that was active during your call to glTexSubImage), to a GLSL sampler2D using glUniform1i).
Anyway, here's the program I wrote: http://litherum.blogspot.com/2013/02/sprites-in-opengl-programmable-pipeline.html Hope you can learn from it!
