a. glUniform1i
b. g|TextureView
c. glUniform
d. glUnitTex

Answer 1

Option A is answer. The function used to manually set a uniform sampler to the correct texture unit in OpenGL is glUniform1i.

Step-by-step explanation:

The function used manually to set a uniform sampler to the proper texture unit is glUniform1i. When working with shaders in OpenGL, uniform variables are used to communicate with the shader programs from the application. In the context of texture units, you first activate a texture unit using glActiveTexture, bind your texture with glBindTexture, and then with glUniform1i, you assign the activated texture unit to the sampler uniform variable in your shader. This process tells the shader which texture unit a sampler should use.

The command takes two arguments: the location of the uniform in the shader, which you can get by using glGetUniformLocation, and the index of the texture unit.The correct function used manually to set a uniform sampler to the proper texture unit is glUniform1i. This function is part of the OpenGL graphics library and is typically used when working with shaders in computer graphics programming. It allows you to specify the texture unit index that corresponds to the uniform sampler in your shader program.
