Question

Which function is used to activate the shader before setting uniforms? select one.

a. setint()
b. set()
c. setui()
d. use()

Answer 1

In computer graphics programming, particularly OpenGL or WebGL, the function 'use()' is called to activate a shader program before setting uniforms like integers or other variables.

Step-by-step explanation:

The function used to activate the shader before setting uniforms is use(). This is typically required in OpenGL or WebGL when working with shaders. Before you can send values (uniforms) to a shader's uniform variables, you must make the specific shader program active, which is done by calling the use() function associated with your shader object or program. After the shader program is in use, you can then call functions like setInt(), set(), or setUI() to set the uniform values.
