Hi all! From what I’ve learned, writing to large Texture3Ds tends to be very slow (especially the Apply() method, since data has to be transferred between CPU and GPU for each operation). Is there a faster way to achieve real-time manipulation of 3D texture values in Unity? I’ve heard about RenderTe…

Thanks a lot, that’s exactly what I was looking for!

[image] Przemyslaw_Zaworski: https://discussions.unity.com/t/727335/8 Let’s say you already have voxel values stored in a Texture3D or an array of voxel values. Is there a way to initialize the RenderTexture with the predefined volume rendering at the beginning of the program?

Yes. For example, at C# side you have (fragments of code): public ComputeShader ScalarFieldCS; ComputeBuffer _VoxelBuffer; void SaveFloatArrayToFile(float[] x, string path) { byte[] a = new byte[x.Length * 4]; System.Buffer.BlockCopy(x, 0, a, 0, a.Length); System.IO.File.WriteAllBytes…
