Rendering 1 million cubelets ?? Is it even possible ?
Hi,
My objective is to render a cube which has 1 million cubelets. So the dimensions are 100*100*100 cubelets. My question is there any possibilty to render 1 million cubelets at a time with a decent frame rate. Here is my code
var cubeinstance : Transform;
var dimension = 10;
function Start ()
{
for (var z = 0; z < dimension; z++)
{
for (var y = 0; y < dimension; y++)
{
for (var x = 0; x < dimension; x++)
{
Instantiate(cubeinstance, Vector3 (x, y, z), Quaternion.identity);
}
}
}
}
Created a cube prefab and assigned it to this script and attached this script with the main camera.
The Problem : If I try to render more than 30*30*30, the framerate drops severely.
Any ideas for optimization ?? Thank you.
firstly: Do you really need to render 1 mil cubes? (What the hell are you doing?)
secondly: take a look at voxels
Unless you plan some x-ray vision feature, you won't need to display all of these cubelets at once, so consider generating only those, that are required and manage them using a pool. If one needs to disappear, return it to the pool. If another one has to be drawn, get it from pool.
I'd say it's impossible to have that many seperate GameObjects, let alone instantiate them at the same time. You could do it minecraft-style and instantiate a custom mesh with textures that creates a mesh of many cubes. Check the various threads on "Minecraft in Unity3D".
