Hey I have a Mesh that consists of about 8000 evenly spaced out bars across the x-axis. I generated this Mesh by creating 8000 Meshes from a CubeGeometry and then merging them into a single Mesh. The reason I merge them into a single Mesh is to improve performance when resizing all the bars at once.

Now my question is, is it possible to somehow increase/reduce the space between the bars without losing performance. Basically I want to achieve this without going through the process of creating the bars from scratch.

I am using a OrthographicLens lense so you can think of it in 2D space.

Greetings,
OK. so you merge two things together like

cool. Well now you want to keep track of the vertices that represent tempMesh inside your FinalMesh. You do this by accessing the subgeometries of FinalMesh. But how do you know which tempMesh is the mesh your talking about? Well for me I created an object that contains this information.

So I have two numbers, the before and after size of my FinalMesh subgeometries. this way I know where in the FinalMesh my tempMesh was.

So now I create a function that goes through the subgeometries, and at the location of tempMesh I edit it’s x y and z

For a better understanding perhaps of what you want to do.

Thanks for the reply, this is exactly what I needed!

Hm repositioning 8000 bars would mean running a loop of 0 to 192000 (24 x-coordinates for each cube) which will definitely effect the FPS. I need to reposition them in a very specific way, I need to increase/decrease the space between them across the x-axis. I’m wondering if there is another way to achieve this without having such a big loop.

resize and reposition or what?

No I don’t want to resize them I just want increase the space between them.

So I start off with the attached image. What I need to do is to increase the space between the bars. In the attached image there are 4px between each bar I want to increase that to 8px for example.

Using your method I would need to loop through all the bars and adjust the verticies for each bar to reposition them to allow for more space between the bars which results in a loop of 0 to 192000 (if I have 8000 bars with 24 verticies each).

I’m wondering if there is another method to achieve this without having to do this loop. I was thinking of maybe somehow using a custom lens… not sure how though or if it’s even possible.

Hmm is it possible to create a transformation matrix for the subgeometry that could use the index of vertexData as a variable, so that the verticies repositioned disproportionally

Whoops, you want to move them all at once, so this bottom post probably means nothing to you

When you cycle through the subgeometry of the FinalMesh that contains your many meshes, you don’t need to cycle through every set of vertices for every cube..

My data object cubeDatas[] is what contains the information for each cube in my giant mesh, meshPartID is th index that represents my one cube, of many.
.start and .end represent the beginning number if the finalMesh subgeometries, before and after the merge

As you see i have mergeNum and mergeNum2, that i store into start and end of my cubeDatas[] object. I figure out the cubes name through nameAsNumber.

Since I know my cubes will never have the same X Y Z coordinates, i figure out they’re name doing this:

For lack of a better idea.

That is why you are only cycling through 1 cube x 24 vertices every time

yeah I need a way to move them all at once :/
