WebUsing Buffers and Images Appropriately Using Buffers and Images Appropriately On both CPU and Intel® Graphics devices, buffers usually perform better than images: more data transfers per read or write operation for buffers with much lower latency. Web8 de abr. de 2024 · So I'm writing the software trilinear interpolation. It works like this: Read cube of 4x4x4 = 64 values form the texture memory. interpolate each of the 16 lines along x-direction to obtain 4x4 set of points. interpolate each of the 4 lines along y-direction to obtain 4 points. interpolate the remaining 4 points along z-direction.
