I use the Three.js canvas inside a tab container but for some unknown reason, the 3D viewport is not inhered the full width & height of the parent element.

@description

I have 2 tabs the first tab is active in the second tab is where I have the 3D viewport (canvas).

I'm trying to add a 2D overlay for a 3D scene in Java3D, part of this overlay is to draw a line from a 2D object to a corresponding point in the 3D scene...

Searched transformation from 3D to 2D and read those threads:

• Translate Java 3D coordinates to 2D screen coordinates

• 3D to 2D projection

from code inside walrus: https://github.com/CAIDA/walrus/blob/master/H3ViewParameters.java

I'm trying to load .obj file from blender to Java3D but error always occur:

com.sun.j3d.utils.image.ImageException: javax.imageio.IIOException: Can't get input stream from URL!

The weirdest thing of it all is that when i load model from web everything is ok but when i import same file to blender and then export it (without any change) it doesn't work.

I'm a beginner in WPF, so I don't understand exactly how C# works with XAML to make the application.

I'm trying to make a software to draw and manipulate 3D geometry. I've followed this example on how to create a 3D scene and was succesful.

But, when I try to put the Viewport3D inside a canvas in XAML (so that I can place other elements like buttons in the UI to manipulate the 3D scene), I can't figure out why the Viewport3D doesn't show up.

I don't want to define everything of the Viewport3D in XAML because I plan to have more complex operations of drawing and manipulation of geometry. And I think it is better to do it in C#.

The MainWindow from the C# file isn't the same on the XAML file?

Here is the window I get:

Here is the code:

I'm making a webgl demo with md2 models. I know that it is an old format but I need to use only md2.

I read the documentation for the md2 format.

I watched how this site works: and used part of it's sources in my program (i saved the author's name in the comments)

I made vertex loading, the model loads great!

But when I'm trying to map the texutre, something strange happens:

First, I thought that it's the problem of fragment shader, but I made an export by using assimp2json, used the data from it and it was drawn as it should draw.

The problem is that assimp2json changed the order vertices in triangles and uvs order, so I can't debug the program using it.

Maybe, someone could help to find the bug, to point to the error in my code?

P. S. since there is no animation, I only use the first frame

The most interesting is that if I will pass unindexed data (just the uvs from the file) it looks more right than the indexed textures:

The problem is that it is wrong in some places, like here:

I'm developing a JavaFX desktop application. In it I want to display some java 3D objects.

The way to do this, as far as I know, is using JavaFX's SwingNode. Java 3d has to be integrated in a Swing component too. So it's a two-step process.

Integrating Java 3D objects with Java Swing

Complete and minimal example composed of the panel I intend to reuse in the FX app and a JFrame that shows it works:
