I have a couple questions about glTexParameter and filtering
1) What is the scope when applying a glTexParameter (specifically the filtering)? Here's a scenario:
- Bind a texture. Set the filters to LINEAR
- Set the texture to "Sampler1" of a shader
- Bind another texture. Set its filters to NEAREST
- Set that texture to "Sampler2" of a shader
- Draw
When I use the textures in a shader, will one be linear and the other be nearest? Or will they both be nearest because it was called last?
2) Is it possible to set the filtering method in GLSL?
Thanks in advance!
