What type of Pixel Interpolation is used by OpenGL?

Question

Hello,

I would like to know what type of Pixel Interpolation is used by OpenGL. Does it use one of the Standard Pixel Interpolation techniques like Nearest Neighbor, Bilinear or Bicubic?

Answer 1

If you mean the various texture filtering methods, you can set nearest neighbor, as well as bilinear (lerp) or even trilinear (interpolating through multiple scaled textures (mipmaps), as well as the adjacent '2d' pixels)

The filtering method van be set independently for magnification as well as minification
