Like said here in the doc, we can create a texture with linear filtering. But in OpenGL, we can set the filtering for example setting linear to nearest after having created the texture with glTexParameteri
.
Can we do so with CUDA?
If not, that would mean we have to recreate a texture with cudaCreateTextureObject
. So as auxiliary question, is cudaCreateTextureObject()
a cheap call ? That seems to be the case because the textures depends on array that have already been uploaded to the GPU, and this defines only the parameters on the textures.
