I have a truck agent that seizes a trailer resource from "trailer" resourcepoolblock (thanks to seize block). I want that both the agent both the resource make a rotation in the 3D animation. I did for the agent, while for the resource i tried: "agent.resourceUnitsOfPool(trailer).trailer1.setRotation(-PI);" But it does not work. What is the right command in order to control the 3D object of the resource? Thanks for the help.

How do I specifically check for compatibility of @keyframes translate3d animations with the browser ?

Please Don't close this question since I've tried many stackoverflow solutions before asking this question.

I want to check whether the browser my webpage runs is compatible for running animations, since many android browsers(Old Ones) are not capable of running them, they just stop displaying output text when animation fails (In MY Case). So, I would like to either stop animations or redirect them to another copy of my same website without any animations :)

P.S I've also tried using @supports, but of no use :(

I am running a model with heavy 3D animation images for agents. At the beginning, the model was running fine, but then I added new agent types with 3D images (without creating any agent instances) and now when it runs the animation window just freezes, even when the model in the background keeps running. While ignoring the 3D window the model runs without any issue. Other than decreasing the size and complexity of the 3D images, is there something that can be done for making the model run bigger 3D instances? Thank you.

I solved the N body problem with Python. My code works perfectly but I have to write manually line animation for each body. I would like to make a loop instead but I did not succeed. Here is the code :

I am reading the following articles 3D animation using matplotlib. It shows the animation in 3D.

I am considering the following scenario:

1. I have a x-y meshgrid, [1,2,...,20] X [1,2,...,20]
2. For each point, a z-value is assigned.
3. Based on 1. and 2., I plot the 3-D gradient graph as the following

Suppose I have 5 20X20 data for z values (.xlsx). Therefore, I get 5 different graphs as above.

Now, I want to plot all 5 graphs in one graph but with a slider such that when I move the slider from 1 to 5, I can get an animation (variation) of the graph but in the same meshgrid.

The code for only one graph (one data) is provided here

I'm using an iframe:

I have a 3d animation who i want to detect colitions with mouse, i try to follow with a ball and this ball is not same position than mouse.

Working example in codepen

This function is a copy paste of this other answer but it dont work for me.

I have a WebGL scene with tens of thousands of polygons (2d on the z=0 plane). Each polygon is composed of approximately 6-12 triangles (18-36 vertices). I would like to apply a random (or random-looking) 3d animation to each shape by applying a 4x4 transformation matrix to all the vertices in each shape.

I know I could do this by assigning a 16 number matrix to each vertex (the same matrix for all 18-36 vertices in the shape). I know this is just a bit the nature of WebGL but it seems somewhat inefficient to have 18-36 identical copies of the same 4x4 matrix.

I was wondering if there are any more efficient ways to do it. For example, is there a way to use only say 20 matrices and randomly assign a matrix to each shape? I am still learning webgl, so I am not sure if that is possible.

I have a file I'd like to parse to json. First item looks as follows:
